The Relevance of Attention Control, Not Working Memory, in Human Factors

OBJECTIVE

Discuss the human factors relevance of attention control (AC), a domain-general ability to regulate information processing functions in the service of goal-directed behavior.

BACKGROUND

Working memory (WM) measures appear as predictors in various applied psychology studies. However, measures of WM reflect a mixture of memory storage and controlled attention making it difficult to interpret the meaning of significant WM-task relations for human factors. In light of new research, complex task performance may be better predicted or explained with new measures of attention control rather than WM.

METHOD

We briefly review the topic of individual differences in abilities in Human Factors. Next, we focus on WM, how it is measured, and what can be inferred from significant WM-task relations.

RESULTS

The theoretical underpinnings of attention control as a high-level factor that affects complex thought and behavior make it useful in human factors, which often study performance in complex and dynamic task environments. To facilitate research on attention control in applied settings, we discuss a validated measure of attention control that predicts more variance in complex task performance than WM. In contrast to existing measures of WM or AC, our measures of attention control only require 3 minutes each (10 minutes total) and may be less culture-bound making them suitable for use in applied settings.

CONCLUSION

Explaining or predicting task performance relations with attention control rather than WM may have dramatically different implications for designing more specific, equitable task interfaces, or training.

APPLICATION

A highly efficient ability predictor can help researchers and practitioners better understand task requirements for human factors interventions or performance prediction.

Ensuring Intervention Fidelity of an Attention Control Arm in a Multisite Randomized Controlled Trial

BACKGROUND

Intervention fidelity is a critical element of randomized controlled trials, yet reporting of intervention fidelity among attention control arms is limited. Lack of fidelity to attention control procedures can affect study outcomes by either overestimating or underestimating the efficacy of the intervention under examination.

OBJECTIVES

This brief report describes the approach researchers took to promote fidelity to the attention control arm of a pediatric palliative care randomized controlled trial funded by the National Institutes of Health.

METHODS

The Informational Meetings for Planning and Coordinating Treatment trial aims to determine the efficacy of a communication intervention that uses care team dyads (i.e., physicians partnered with nurses or advanced practice providers) to engage parents of children with cancer who have a poor prognosis in structured conversations about prognostic information, goals of care, and care planning. The intervention is compared with an attention control arm, which provides parents with structured conversations on common pediatric cancer education topics, such as talking to their child about their cancer, clinical trials, cancer treatment, side effects, and so forth. National Institutes of Health guidelines for assessing and implementing strategies to promote intervention fidelity were used to design (a) the attention control arm of a randomized controlled trial, (b) related attention control arm training, and (c) quality assurance monitoring.

RESULTS

Attention control study procedures were designed to mirror that of the intervention arm (i.e., same number, frequency, and time spent in study visits). Cluster randomization was used to allocate care team dyads to one arm of the randomized controlled trial. Care team dyads assigned to the attention control arm participated in online training sessions to learn attention control procedures, the different roles of research team members, and quality assurance methods. Fidelity to attention control procedures is assessed by both the interveners themselves and a quality assurance team.

DISCUSSION

Study design, training, and delivery are all critical to attention control fidelity. Baseline training often needs to be supplemented with booster training when time gaps occur between study start-up and implementation. Quality assurance procedures are essential to determine whether interveners consistently deliver attention control procedures correctly.

The relationship between worry and academic performance: examining the moderating role of attention control

BACKGROUND

Worry is frequently associated with reduced cognitive performance, through consumption of attention control resources. Assessing attention control during acute worry may better reflect cognitive performance in real-world scenarios. This study examined whether attention control (assessed at rest and under acute worry) moderates the relationship between worry and academic performance.

METHODS

Worry (Penn State Worry Questionnaire) and academic performance (examination grades) were assessed in 87 undergraduates, with attention control (antisaccade performance) measured at baseline and following worry induction.

RESULTS

When assessed at rest, attention control did not moderate the relationship between trait worry and academic performance. However, under acute worry, attention control significantly moderated the relationship between worry and academic performance (p = .05, f2 = 0.14), such that at low levels of attention control under worry, higher trait worry was significantly associated with lower academic performance. At high levels of attention control under worry, however, the relationship between trait worry and academic performance was not significant.

CONCLUSIONS

Findings suggest that worry may shape performance according to attention control levels, with attention control's moderating role being more pronounced under conditions of acute worry. These results provide preliminary evidence that attention control assessed under worry may better predict real-world performance, compared to assessment at rest.

Induced emotion counter-regulation affects attentional inhibition of emotional information: ERP evidence from a randomized manipulation approach

Automatic emotion counter-regulation refers to an unintentional attentional shift away from the current emotional state and toward information of the opposite valence. It is a useful emotion regulation skill that prevents the escalation of current emotional state. However, the cognitive mechanisms of emotion counter-regulation are not fully understood. Using a randomization approach, this study investigated how automatic emotion counter-regulation impacted attentional inhibition of emotional stimuli, an important aspect of emotion processing closely associated with emotion regulation and mental health. Forty-six university students were randomly assigned to an emotion counter-regulation group and a control group. The former group watched an anger-inducing video to evoke automatic emotion counter-regulation of anger, while the latter group watched an emotionally neutral video. Next, both groups completed a negative priming task of facial expressions with EEG recorded. In the emotion counter-regulation group, we observed an enhanced attentional inhibition of the angry, but not happy, faces, as indicated by a prolonger response time, a larger N2, and a smaller P3 in response to angry versus happy stimuli. These patterns were not observed in the control group, supporting the role of elicited emotion counter-regulation of anger in causing these modulation patterns in responses.

Explaining the Validity of the ASVAB for Job-Relevant Multitasking Performance: The Role of Placekeeping Ability

Scores on the Armed Services Vocational Aptitude Battery (ASVAB) predict military job (and training) performance better than any single variable so far identified. However, it remains unclear what factors explain this predictive relationship. Here, we investigated the contributions of fluid intelligence (Gf) and two executive functions-placekeeping ability and attention control-to the relationship between the Armed Forces Qualification Test (AFQT) score from the ASVAB and job-relevant multitasking performance. Psychometric network analyses revealed that Gf and placekeeping ability independently contributed to and largely explained the AFQT-multitasking performance relationship. The contribution of attention control to this relationship was negligible. However, attention control did relate positively and significantly to Gf and placekeeping ability, consistent with the hypothesis that it is a cognitive "primitive" underlying the individual differences in higher-level cognition. Finally, hierarchical regression analyses revealed stronger evidence for the incremental validity of Gf and placekeeping ability in the prediction of multitasking performance than for the incremental validity of attention control. The results shed light on factors that may underlie the predictive validity of global measures of cognitive ability and suggest how the ASVAB might be augmented to improve its predictive validity.

The use of mentalization-based techniques in online psychodynamic child psychotherapy

Objective: Psychodynamic child psychotherapy is an evidence-based approach for a range of child mental health difficulties and needs to constantly adapt to meet the needs of children. This study is the first to investigate whether the use of mentalization-based interventions (i.e., a focus on promoting attention control, emotion regulation, and explicit mentalization) predicted a good therapeutic outcome in online psychodynamic child therapy sessions conducted during the COVID-19 pandemic. Methods: The sample included 51 Turkish children (Mage = 7.43, 49% girls) with mixed emotional and behavioral problems. Independent raters coded 203 sessions from different phases in each child's treatment using the Mentalization-Based Treatment for Children Adherence Scale (MBT-CAS). Results: Multilevel modeling analyses showed children with higher emotional lability benefited more from attention control interventions compared to those with lower emotional lability. Discussion: Interventions that focus on developing the basic building blocks of mentalizing may be effective components of therapeutic action for online delivery of psychodynamic child psychotherapy, especially for children with greater emotional lability.

Individual differences in attention control and the processing of phonological contrasts in a second language

This study investigated attention control in L2 phonological processing from a cognitive individual differences perspective, to determine its role in predicting phonological acquisition in adult L2 learning. Participants were 21 L1-Spanish learners of English, and 19 L1-English learners of Spanish. Attention control was measured through a novel speech-based attention-switching task. Phonological processing was assessed through a speeded ABX categorization task (perception) and a delayed sentence repetition task (production). Correlational analyses indicated that learners with more efficient attention switching skill and faster speed in correctly identifying the target phonetic features in the speech dimension under focus could perceptually discriminate L2 vowels at higher processing speed, but not at higher accuracy rates. Thus, attentional flexibility provided a processing advantage for difficult L2 contrasts but did not predict the extent to which precise representations for the target L2 vowels had been established. However, attention control was related to L2 learners' ability to distinguish the contrasting L2 vowels in production. In addition, L2 learners' accuracy in perceptually distinguishing between two contrasting vowels was significantly related to how much of a quality distinction between them they could make in production.

Allostasis and metastasis: The yin and yang of childhood self-regulation

Most research has studied self-regulation by presenting experimenter-controlled test stimuli and measuring change between baseline and stimulus. In the real world, however, stressors do not flash on and off in a predetermined sequence, and there is no experimenter controlling things. Rather, the real world is continuous and stressful events can occur through self-sustaining interactive chain reactions. Self-regulation is an active process through which we adaptively select which aspects of the social environment we attend to from one moment to the next. Here, we describe this dynamic interactive process by contrasting two mechanisms that underpin it: the "yin" and "yang" of self-regulation. The first mechanism is allostasis, the dynamical principle underlying self-regulation, through which we compensate for change to maintain homeostasis. This involves upregulating in some situations and downregulating in others. The second mechanism is metastasis, the dynamical principle underling dysregulation. Through metastasis, small initial perturbations can become progressively amplified over time. We contrast these processes at the individual level (i.e., examining moment-to-moment change in one child, considered independently) and also at the inter-personal level (i.e., examining change across a dyad, such as a parent-child dyad). Finally, we discuss practical implications of this approach in improving the self-regulation of emotion and cognition, in typical development and psychopathology.

Working Memory Capacity Depends on Attention Control, but Not Selective Attention

Working memory and attention are interrelated constructs that are sometimes even considered indistinguishable. Since attention is not a uniform construct, it is possible that different types of attention affect working memory capacity differently. To clarify this issue, we investigated the relationship between working memory capacity and various components of attention. The sample consisted of 136 healthy adult participants aged 18 to 37 years (M = 20.58, SD = 2.74). Participants performed tasks typically used to assess working memory (operation span, change detection, simple digit span, and adaptive digit span tasks), selective attention (visual search task), and attention control (Stroop and antisaccade tasks). We tested several models with working memory and attention, either as a unitary factor or being divided into selective attention and attention control factors. A confirmatory factor analysis showed that the model with three latent variables-working memory capacity, attention control, and selective attention-fit the data best. Results showed that working memory and attention are distinct but correlated constructs: working memory capacity was only related to attention control, whereas attention control was related to both constructs. We propose that differences in working memory capacity are determined only by the ability to maintain attention on the task, while differences in the ability to filter out non-salient distractors are not related to working memory capacity.

The effect of mindfulness on social media addiction among Chinese college students: A serial mediation model

Introduction

The COVID-19 pandemic has exacerbated social media addiction (SMA), making it urgent to find effective interventions for social media addiction. Evidence has shown that mindfulness might be an effective intervention for social media addiction. However, psychological mechanisms by which mindfulness reduce social media use remain unclear. Here, we further addressed this issue to examine whether attentional control and fear of missing out (FOMO) mediate the relationship between mindfulness and SMA.

Methods

We recruited 446 college students from two universities in China and analyzed the data.

Results

The results suggest that there are mediation effects of attentional control and FOMO between mindfulness and SMA through 3 paths: path 1, mindfulness → attention control → SMA (-0.04); path 2, mindfulness → FOMO → SMA (-0.22); and path 3, mindfulness → attention control → FOMO → SMA (-0.05).

Discussion

Therefore, mindfulness-based interventions may be an effective way to alleviate social media addiction, especially mindfulness-based interventions targeting FOMO. At the end of the article, we also discussed the limitations of this study.

Intra-individual variability in task performance after cognitive training is associated with long-term outcomes in children

The potential benefits and mechanistic effects of working memory training (WMT) in children are the subject of much research and debate. We show that after five weeks of school-based, adaptive WMT 6-9 year-old primary school children had greater activity in prefrontal and striatal brain regions, higher task accuracy, and reduced intra-individual variability in response times compared to controls. Using a sequential sampling decision model, we demonstrate that this reduction in intra-individual variability can be explained by changes to the evidence accumulation rates and thresholds. Critically, intra-individual variability is useful in quantifying the immediate impact of cognitive training interventions, being a better predictor of academic skills and well-being 6-12 months after the end of training than task accuracy. Taken together, our results suggest that attention control is the initial mechanism that leads to the long-run benefits from adaptive WMT. Selective and sustained attention abilities may serve as a scaffold for subsequent changes in higher cognitive processes, academic skills, and general well-being. Furthermore, these results highlight that the selection of outcome measures and the timing of the assessments play a crucial role in detecting training efficacy. Thus, evaluating intra-individual variability, during or directly after training could allow for the early tailoring of training interventions in terms of duration or content to maximise their impact.

Strategy and processing speed eclipse individual differences in control ability in conflict tasks

Response control or inhibition is one of the cornerstones of modern cognitive psychology, featuring prominently in theories of executive functioning and impulsive behavior. However, repeated failures to observe correlations between commonly applied tasks have led some theorists to question whether common response conflict processes even exist. A challenge to answering this question is that behavior is multifaceted, with both conflict and nonconflict processes (e.g., strategy, processing speed) contributing to individual differences. Here, we use a cognitive model to dissociate these processes; the diffusion model for conflict tasks (Ulrich et al., 2015). In a meta-analysis of fits to seven empirical datasets containing combinations of the flanker, Simon, color-word Stroop, and spatial Stroop tasks, we observed weak (r < .05) zero-order correlations between tasks in parameters reflecting conflict processing, seemingly challenging a general control construct. However, our meta-analysis showed consistent positive correlations in parameters representing processing speed and strategy. We then use model simulations to evaluate whether correlations in behavioral costs are diagnostic of the presence or absence of common mechanisms of conflict processing. We use the model to impose known correlations for conflict mechanisms across tasks, and we compare the simulated behavior to simulations when there is no conflict correlation across tasks. We find that correlations in strategy and processing speed can produce behavioral correlations equal to, or larger than, those produced by correlated conflict mechanisms. We conclude that correlations between conflict tasks are only weakly informative about common conflict mechanisms if researchers do not control for strategy and processing speed.

An examination of relations between baseline pupil measures and cognitive abilities

Examining individual differences in pupil size and pupillary dynamics have revealed important insights into the nature of individual differences in cognitive abilities like working memory capacity, long-term memory, attention control, and fluid intelligence. These findings are often tied to the locus coeruleus-norepinephrine (LC-NE) system, as this system has a tight temporal correlation with pupil diameter. Some recent research has demonstrated positive correlations between resting pupil size and cognitive ability, specifically fluid intelligence. The present study attempted to replicate such relations. Across three studies, a large sample of participants (N = 845) completed batteries of cognitive ability measures and measures of resting pupil size and pupillary hippus (fluctuations in pupil diameter). The cognitive measures comprised tasks previously used to measure attention control, visual short-term memory capacity, fluid intelligence, working memory capacity, and visuospatial ability. At the factor level, cognitive ability and pupil size correlated near zero. We did observe some limited evidence for a negative correlation between resting pupillary hippus and cognitive ability. Given the null findings in the present data, we encourage further replication of relations between resting pupil measures and cognitive abilities before making any strong theoretical conclusions about such relations.

Attention Control in Children With ADHD: An Investigation Using Functional Near Infrared Spectroscopy (fNIRS)

Attention problems are a predominant contributor to near- and far-term functional outcomes in attention-deficit/hyperactivity disorder (ADHD); however, most interventions focus on improving the alerting attentional network, which has failed to translate into improved learning for a majority of children with ADHD. Comparatively less is known regarding the executive attentional network and its overarching attention control process, which governs the ability to maintain relevant information in a highly active, interference-free state, and is intrinsic to a broad range of cognitive functions. This is the first study to compare attention control abilities in children with ADHD and typically developing (TD) children using the Visual Array Task (VAT) and to simultaneously measure hemodynamic functioning (oxyHb) using functional Near-Infrared Spectroscopy (fNIRS). Nineteen children with ADHD Combined type and 18 typically developing (TD) children aged 8 to 12 years were administered the VAT task while prefrontal activity was monitored using fNIRS. Results revealed that children with ADHD evinced large magnitude deficits in attention control and that oxyHb levels in the left dorsal lateral prefrontal cortex (dlPFC) were significantly greater in children with ADHD relative to TD children. These findings suggest that poor attention control abilities in children with ADHD may be related to increased left dlPFC activation in response to an underdeveloped and/or inefficient right dlPFC. The need to design interventions that target and strengthen attention control and its corresponding neural network is discussed based on the likelihood that attention control serves as the potential quaesitum for understanding a wide array of ADHD-related deficits.

Roles of P300 and Late Positive Potential in Initial Romantic Attraction

Initial romantic attraction (IRA) refers to a series of positive reactions to potential romantic partners at the initial encounter; it evolved to promote mate selection, allowing individuals to focus their mating efforts on their preferred potential mates. After decades of effort, we now have a deeper understanding of the evolutionary value and dominant factors of IRA; however, little is known regarding the brain mechanisms related to its generation and evaluation. In this study, we combined classic event-related potential analysis with dipole-source analysis to examine electroencephalogram (EEG) signals generated while participants assessed their romantic interest in potential partners. The EEG signals were categorized into IRA-engendered and unengendered conditions based on behavioral indicators. We found that the faces elicited multiple late positivities, including P300 over the occipital-parietal regions and late positive potentials (LPPs) over the anterior regions. When compared to faces that did not engender IRA, faces that did engender IRA elicited (1) enhanced P300 over the parietal regions and heightened neural activity in the insula and cingulate cortex and (2) larger LPPs over the anterior regions and heightened neural activity in the orbitofrontal cortex, dorsolateral prefrontal cortex, cingulate cortex, frontal eye field, visual cortex, and insula. These results suggest IRA is generated and evaluated by an extensive brain network involved in emotion processing, attention control, and social evaluations. Furthermore, these findings indicate that P300 and LPP may represent different cognitive processes during IRA.

The Moderating Role of Attention Control in the Relationship Between Pain Catastrophizing and Negatively-Biased Pain Memories in Youth With Chronic Pain

The present study examined the role of attention control in understanding the development of negatively-biased pain memories as well as its moderating role in the relationship between pain catastrophizing and negatively-biased pain memories. Youth with chronic pain (N = 105) performed a cold pressor task (CPT) and completed self-report measures of state/trait pain catastrophizing and attention control, with the latter comprising both attention focusing and attention shifting. Two weeks after the CPT, youth's pain-related memories were elicited via telephone allowing to compute pain and anxiety memory bias indices (ie, recalling pain intensity or pain-related anxiety, respectively, as higher than initially reported). Results indicated no main effects of attention control and pain catastrophizing on pain memories. However, both components of attention control (ie, attention focusing and attention shifting) moderated the impact of pain catastrophizing on youth's memory bias, with opposite interaction effects. Specifically, whereas high levels of attention shifting buffered the influence of high pain catastrophizing on the development of pain memory bias, high levels of attention focusing strengthened the influence of high pain catastrophizing on the development of anxiety memory bias. Interaction effects were confined to trait catastrophizing (ie, not state catastrophizing). Theoretical and clinical implications are discussed. PERSPECTIVE: This article investigates the role of attention control in the development of negatively-biased pain memories in children with chronic pain. Findings underscore the importance of targeting differential components of attention control and can inform intervention efforts to minimize the development of negatively biased pain memories in youth with chronic pain.

Context and attention control determine whether attending to competing information helps or hinders learning in school-aged children

Attention control regulates efficient processing of goal-relevant information by suppressing interference from irrelevant competing inputs while also flexibly allocating attention across relevant inputs according to task demands. Research has established that developing attention control skills promote effective learning by minimizing distractions from task-irrelevant competing information. Additional research also suggests that competing contextual information can provide meaningful input for learning and should not always be ignored. Instead, attending to competing information that is relevant to task goals can facilitate and broaden the scope of children's learning. We review this past research examining effects of attending to task-relevant and task-irrelevant competing information on learning outcomes, focusing on relations between visual attention and learning in childhood. We then present a synthesis argument that complex interactions across learning goals, the contexts of learning environments and tasks, and developing attention control mechanisms will determine whether attending to competing information helps or hinders learning. This article is categorized under: Psychology > Attention Psychology > Learning Psychology > Development and Aging.

Vocabulary Size Is a Key Factor in Predicting Second Language Lexical Encoding Accuracy

This study investigates the relationship between the accuracy of second language lexical representations and perception, phonological short-term memory, inhibitory control, attention control, and second language vocabulary size. English-speaking learners of Spanish were tested on their lexical encoding of the Spanish /ɾ-r/, /ɾ-d/, /r-d/, and /f-p/ contrasts through a lexical decision task. Perception ability was measured with an oddity task, phonological short-term memory with a serial non-word recognition task, attention control with a flanker task, inhibitory control with a retrieval-induced inhibition task, and vocabulary size with the X_Lex vocabulary test. Results revealed that differences in perception performance, inhibitory control, and attention control were not related to differences in lexical encoding accuracy. Phonological short-term memory was a significant factor, but only for the /r-ɾ/ contrast. This suggests that when representations contain sounds that are differentiated along a dimension not used in the native language, learners with higher phonological short-term memory have an advantage because they are better able to hold the relevant phonetic details in memory long enough to be transferred to long-term representations. Second language vocabulary size predicted lexical encoding across three of the four contrasts, such that a larger vocabulary predicted greater accuracy. This is likely because the acquisition of more phonologically similar words forces learners’ phonological systems to create more detailed representations in order for such words to be differentiated. Overall, this study suggests that vocabulary size in the second language is the most important factor in the accuracy of lexical representations.

The mediating role of attention control in the link between multitasking with social media and academic performances among adolescents

Prevalence of using social media services while learning, studying and doing homework is increasing rapidly among adolescents in the digital age. Although there is evidence for negative consequences of multitasking with social media, little is known about impact of social media multitasking from perspective attention control of self-regulation. This study examined the mediating role of attention control as a component of self-regulation in the link between social media multitasking and academic performances in a sample of adolescents who were recruited from high school students (N = 637). A correlational research design was used in the study. To examine study hypothesis, a mediation model was tested using simple mediation analysis in macro PROCESS (model 4). Results have revealed that attention control of self-regulation mediated the negative relationship between multitasking with social media and academic performances of the students. Multitasking with social media was a negatively significant predictor of academic performance, whereas attention control positively predicted academic performance. It implies that more frequent multitasking behavior with social media had lower attention control and poorer academic performances. The conclusions of the study suggest a critical role for attention control in decreasing negative effect of multitasking with social media on academic performances of adolescents in high school setting. Implications and suggestions for future studies are proposed.

Attention or Distraction? The Impact of Mobile Phone on Users' Psychological Well-Being

Cumulative evidence has demonstrated that mobile phone distraction, in particular among emerging adults, is a growing problem. Considerable efforts have been made to contribute to the literature by proposing cognitive emotion pre-occupation which acts as an underlying mechanism through which mobile phone distraction results in a reduction in psychological well-being. The proposed model is supported by distraction-conflict theory which reveals that users, with high attention control, are better at coping with the negative consequences of mobile phone distraction. The data, consisting of 914 University students in China, was analyzed using statistical tools. The results support that mobile phone distraction has a significant positive relationship with cognitive emotional pre-occupation which negatively affects users' psychological well-being. Our findings also reveal that attention control moderated the mediation effect of cognitive emotional pre-occupation in association with mobile phone distraction and psychological well-being. The theoretical and practical implications are also discussed along with limitations and future research.

An Adaptable, Open-Access Test Battery to Study the Fractionation of Executive-Functions in Diverse Populations

The umbrella-term 'executive functions' (EF) includes various domain-general, goal-directed cognitive abilities responsible for behavioral self-regulation. The influential unity and diversity model of EF posits the existence of three correlated yet separable executive domains: inhibition, shifting and updating. These domains may be influenced by factors such as socioeconomic status (SES) and culture, possibly due to the way EF tasks are devised and to biased choice of stimuli, focusing on first-world testees. Here, we propose a FREE (Free Research Executive Function Evaluation) test battery that includes two open-access tasks for each of the three abovementioned executive domains to allow latent variables to be obtained. The tasks were selected from those that have been shown to be representative of each domain, that are not copyrighted and do not require special hardware/software to be administered. These tasks were adapted for use in populations with varying SES/schooling levels by simplifying tasks/instructions and using easily recognized stimuli such as pictures. Items are answered verbally and tasks are self-paced to minimize interference from individual differences in psychomotor and perceptual speed, to better isolate executive from other cognitive abilities. We tested these tasks on 146 early adolescents (aged 9-15 years) of both sexes and varying SES, because this is the age group in which the executive domains of interest become distinguishable and in order to confirm that SES effects were minimized. Performance was determined by Rate Correct Scores (correct answers divided by total time taken to complete blocks/trial), which consider speed-accuracy trade-offs. Scores were sensitive to the expected improvement in performance with age and rarely/inconsistently affected by sex and SES, as expected, with no floor or ceiling effects, or skewed distribution, thus suggesting their adequacy for diverse populations in these respects. Using structural equation modeling, evidence based on internal structure was obtained by replicating the three correlated-factor solution proposed by the authors of the model. We conclude that the FREE test battery, which is open access and described in detail, holds promise as a tool for research that can be adapted for a wide range of populations, as well as altered and/or complemented in coming studies.

Polish adaptation of emotional Stroop test in assessment of pedophilia - a pilot study

OBJECTIVES

A pilot study was conducted in order to construct a Polish adaptation of emotional Stroop test in assessment of pedophilia.

METHODS

The study consisted of two stages. The first stage involved creating test material by ranking words in adequate lists by competent experts. The second stage consisted of empirical verification of the principle of emotional Stroop test in a non-clinical population.

RESULTS

Based on the assessment of five competent experts, words were ordered from the most to the least sexually arousing (Kendall's W from 0.368 to 0.693). Six ranked lists were obtained, and the competent experts were subsequently asked to assess whether these lists were suitable for the study (Lawshe's Content Validity Ratio from 0.6 to 1.0). Two categories of words were merged. Five ranked lists were obtained, and the competent experts were subsequently asked again to assess whether these lists were suitable for the study (Lawshe's Content Validity Ratio 1.0). The created lists of words were approved by allcompetent experts. Based on the experimental study conducted on a non-clinical population, it was shown that, in accordance with the principle of the test, the mean response time for sexually related words was longer that for neutral words. The mean response time for children-related words did not differ significantly from response time for neutral words.

CONCLUSIONS

Based on the study with competent experts and conducted experiments, an initial Polish adaptation of the emotional Stroop test for diagnosis of pedophilia has been created. Further studies with persons with pedophilia are needed to implement the test in clinical setting.

Cognitive Control in Suicide Ideators and Suicide Attempters

There is a need to understand more of the risk factors involved in the process from suicide ideation to suicide attempt. Cognitive control processes may be important factors in assessing vulnerability to suicide. A version of the Stroop procedure, Delis-Kaplan Executive Function System (D-KEFS) Color-Word Interference Test (CWIT) and Behavior Rating Inventory of Executive Function (BRIEF-A) were used in this study to test attention control and cognitive shift, as well as to assess everyday executive function of 98 acute suicidal psychiatric patients. The Columbia Suicide History Form (CSHF) was used to identify a group of suicide ideators and suicide attempters. Results showed that suicide attempters scored lower on attention control than suicide ideators who had no history of attempted suicide. The self-report in the BRIEF-A inventory did not reflect any cognitive differences between suicide ideators and suicide attempters. A logistic regression analysis showed that a poorer attention control score was associated with the suicide attempt group, whereas a poorer cognitive shift score was associated with the suicide ideation group. The results found in this study suggest that suicide attempters may struggle with control of attention or inhibiting competing responses but not with cognitive flexibility.

Spontaneous Distractor Reactivation With Age: Evidence for Bound Target-Distractor Representations in Memory

Reduced attentional control with age is associated with the processing and maintenance of task-irrelevant information in memory. Yet the nature of these memory representations remains unclear. We present evidence that, relative to younger adults (n = 48), older adults (n = 48) both (a) store simultaneously presented target and irrelevant information as rich, bound memory representations and (b) spontaneously reactivate irrelevant information when presented with previously associated targets. In a three-stage implicit reactivation paradigm, re-presenting a target picture that was previously paired with a distractor word spontaneously reactivated the previously associated word, making it become more accessible than an unreactivated distractor word in a subsequent implicit memory task. The accessibility of reactivated words, indexed by priming, was also greater than the degree of distractor priming shown by older adults in a control condition (n = 48). Thus, reduced attentional control influences the processing and representation of incoming information.

The Predicting Power of Cognitive Fluency for the Development of Utterance Fluency in Simultaneous Interpreting

Although simultaneous interpreting (SI) is generally recognized as a highly demanding cognitive activity in nature, the role of cognitive processes in SI fluency is yet to be determined. While utterance fluency refers to the set of objectively determined oral features of utterances, cognitive fluency means the speaker’s efficient mobilization and integration of underlying cognitive processes responsible for utterance production. An investigation into the relationship of the two dimensions of fluency helps to reveal the cognitive bases of interpreting. This study explores the predicting power of cognitive fluency in the utterance fluency development of L2 (English)–L1 (Chinese) SI output of trainee interpreters. Cognitive fluency was operationalized as measures of lexical access, linguistic attention control, and working memory capacity. Measures of utterance fluency were obtained through simulated SI tasks under conditions of low and high input rates. Twenty-eight trainees interpreted two speeches, one with a high input rate and the other with a low input rate, at the beginning and end of an SI training period of 13 weeks. A bilingual corpus of the participants’ SI output was built, and indicators of SI utterance fluency were annotated systematically. Utterance fluency was indexed by the speech rate, mean length of run, phonation time ratio, mean number of silent pauses, and mean number of disfluencies. Results of analyses indicated that (1) the predicting power of cognitive fluency for SI utterance fluency development was only shown under high cognitive load over a training period of 13 weeks; (2) predictors for the development of SI utterance fluency tended to be the efficiency of cognitive processes involved in the target language production stage; and (3) the inclusion of measures of working memory capacity significantly increased the predicting power of cognitive fluency for SI utterance fluency development. This study for the first time provides evidence for the role of cognitive fluency in trainee interpreters’ SI utterance fluency development, having implications for the theoretical framework of cognitive fluency and the information processing mechanism in interpreting process, as well as for interpreter aptitude tests and interpreting pedagogy.

The Effects of a Mindfulness-Based Program on the Incidence of Injuries in Young Male Soccer Players

The authors tested the effectiveness of a mindfulness-based program in reducing sport-injury incidence. A total of 168 young male elite soccer players were randomly assigned to mindfulness and control groups. The mindfulness group consisted of seven sessions based on the mindfulness-acceptance-commitment approach, while the control group consisted of seven presentations on sport-injury psychology. Athlete exposure and injury data were recorded during one season. State and trait mindfulness, sport anxiety, stress, and attention control of participants were assessed. Number of injuries, average of injuries per team, and days lost to injury in the mindfulness group were significantly lower than those in the control group. Mindfulness and attention control were lower and sport anxiety and stress were higher in injured players than in noninjured players. Psychological variables were associated with injury. Mindfulness training may reduce the injury risk of young soccer players due to improved mindfulness and attention control and reduced sport anxiety.

Strength of Ventral Tegmental Area Connections With Left Caudate Nucleus Is Related to Conflict Monitoring

Successful learning requires the control of attention to monitor performance and compare actual versus expected outcomes. Neural activity in the ventral tegmental area (VTA) has been linked to attention control in animals. However, it is unknown whether the strength of VTA connections is related to conflict monitoring in humans. To study the relationship between VTA connections and conflict monitoring, we acquired diffusion tensor imaging (DTI) data on 50 second language learners who we have previously studied. We performed probabilistic tractography to document VTA connections with the dorsal striatum and the anterior cingulate cortex (ACC), and administered the Flanker task in which subjects were required to monitor and report conflicts in visual stimuli. Reaction times (RTs) indexed students’ conflict monitoring. Probabilistic tractography revealed distinct neural connections between the VTA and the dorsal striatum and ACC. Correlational analyses between tractography and flanker RTs revealed that the strength of VTA connections with the left caudate nucleus was negatively correlated with RTs recorded in the presence of conflicts. This provides the first evidence to suggest that VTA connections with the left caudate nucleus are related to conflict monitoring in humans.

Does Maternal Warmth Moderate Longitudinal Associations Between Infant Attention Control and Children's Inhibitory Control?

Attention control (AC) is thought to play an important role in the development of inhibitory control (IC) in children, yet there are few longitudinal studies of this association. This study used a prospective parent-child adoption design (N = 361 children) to examine whether maternal warmth at child age 27 months moderated the link between AC during infancy and IC during childhood. Tobit regression analyses indicated that low levels of infant AC at 9 months predicted low levels of IC at 6 years, controlling for birth parent IC, prenatal risk, infant distress to limitations, child sex, and openness of adoption. Adoptive mother warmth at 27 months moderated this association. In the context of higher levels of maternal warmth, the longitudinal association between low AC and low IC was attenuated. Thus, high levels of early maternal warmth may help diminish the effects of extant risk for IC deficits.

Fidelity of a peer-led asthma self-management intervention and its attention control in a multisite study of urban adolescents

In this paper we compare the fidelity of a Peer-Led Asthma Self-Management Program for Adolescents (PLASMA) and its attention control. A randomized controlled trial involving two groups-the PLASMA group and the attention control group-was conducted between 2015 and 2018. Adolescents 12-17 years old (N = 259) in three cities in the United States received asthma self-management education implemented at a day camp, followed by bi-monthly, follow-up contact for 12 months. Thirty-five peer leaders and six adult educators implemented education sessions for the PLASMA and the attention control groups, respectively. The intervention was the peer-led delivery of the content instead of the educational content itself. This study compares the extent to which the education sessions and follow-up contacts were implemented in accordance with the study protocol by the peer and adult educators. Most topics on asthma knowledge and skills (85-95%) were delivered as intended at an adequate pace in both groups. Peer leaders missed more content in the psychosocial domain than adult educators-14% versus 0%, respectively (t = -3.7; p = .010). PLASMA participants reported high content and time fidelity for all education sessions (94% to 97.6%). Greater success in bimonthly follow-up contacts was reported in the attention control groups, with 4.6 ( ± 1.5) contacts on average compared to 2.6 (±2.02) in the PLASMA groups (t = 9.02; p < .001). Most components of the asthma self-management program were implemented with high fidelity in both groups. The relatively low fidelity in delivering psychosocial content and performing follow-up contacts in the PLASMA groups underscores the need for intensive training to enhance peer leaders' competency with managing these aspects of PLASMA to maximize fidelity. Peer leaders can implement asthma self-management educational components of the intervention with high fidelity similar to adult educators.

Attention control group activities and perceived benefit in a trial of a behavioral intervention for older adults

Researchers trialing behavioral interventions often use attention control groups, but few publish details on attention control activities or perceived benefit. Attention control groups receive the same dose of interpersonal interaction as intervention participants but no other elements of the intervention, to control for the benefits of attention that may come from behavioral interventions. Because intervention success is analyzed compared to control conditions, it is useful to examine attention control content and outcomes. The purpose of this study is to report on attention control visit activities and their perceived benefit in a randomized control trial. The trial tested an aging-in-place intervention comprised of a series of participant goal-directed visits facilitated by an occupational therapist, nurse, and handyman. The attention control group participants received visits from a lay person. We report on the number and length of visits received, types of visit activities that participants chose, and how much visit time was spent on each activity, based on the attention visitor's records. We report on participant perceptions of benefit based on a 10-item Likert-scale survey. The attention control group participants (n = 148) were cognitively intact, at least 65 years old, with at least one Instrumental Activities of Daily Living. Attention control group participants most often chose conversation (20.1% of visit time), and playing games (18.7%), as visit activities. The majority of attention control group participants (63.4%) reported "a great deal" of perceived benefit. Attention control group visits may be an appropriate comparison in studies of behavioral interventions for community-dwelling older adults.

Threat-of-shock decreases emotional interference on affective stroop performance in healthy controls and anxiety patients

Patients with anxiety disorders suffer from impaired concentration, potentially as a result of stronger emotional interference on attention. Studies using behavioural measures provide conflicting support for this hypothesis. Elevated state anxiety may be necessary to reliably document differences in emotional interference in patients versus healthy controls. The present study examines the effect of experimentally induced state anxiety (threat-of-shock) on attention interference by emotional stimuli. Anxiety patients (n = 36) and healthy controls (n = 32) completed a modified affective Stroop task during periods of safety and threat-of-shock. Results indicated that in both patients and controls, threat decreased negative, but not positive or neutral, emotional interference on attention (both p < .001). This finding supports a threat-related narrowing of attention whereby a certain level of anxiety decreases task-irrelevant processing.

Exposure to infant images enhances attention control in mothers

Viewing cute images has been reported to promote performance on tasks requiring carefulness, possibly related to an enhanced positive emotional state. However, it is unclear whether viewing infant images also enhances attention control in mothers. Therefore, this experimental study examined whether exposure to images of infants affected mothers' performance on a visual search task, studying associations with happy facial expressivity. Mothers (N = 101, M_age  = 30.88) were randomly assigned to one of two conditions in which they either viewed images of infants or images of adults. Before and after viewing images, mothers performed a visual search task. Mothers' happy facial expressions at baseline and when viewing images were analysed. Viewing images of infants, in contrast to viewing images of adults, improved task performance indexed by accurateness, but not the number of correct responses. Images of infants elicited happy facial expressivity, which was associated with the number of correct responses on the visual search task. This study showed that viewing images of infants evokes happy facial expressions in mothers and can improve mothers' performance on a perceptual-cognitive task requiring attention control. Mothers' responses to infant images may be explained as an attentional preparedness for caregiving.

Approaching Cognitive Behavior Therapy For Generalized Anxiety Disorder From A Cognitive Process Perspective

Generalized anxiety disorder (GAD), with uncontrollable worry at its core, is a common psychological disorder with considerable individual and societal costs. Cognitive behavior therapy (CBT) is recommended as the first-line treatment for GAD; however, further investigation into its effectiveness in routine clinical care is indicated and improvement is required in treatment outcomes for worry. Improvements to CBT need to be guided by experimental research that identifies key mechanisms maintaining core aspects of the disorder. This paper summarizes how theory-driven experimental research guided selection and refinements of CBT techniques originally developed by Borkovec and Costello, to target key cognitive processes that maintain worry in GAD. Hirsch and Mathews' model specifies three key research-supported processes that maintain uncontrollable worry in GAD: implicit cognitive biases such as negative interpretation bias and attention bias, generalized verbal thinking style, and impaired ability to re-direct attentional control away from worry. Specific CBT techniques outlined in this paper aim to target these key processes. Clinical data from clients treated using our refined CBT protocol for GAD in a routine clinical care service with a special interest in anxiety disorders were collected as part of service procedures. Large pre-to-posttreatment effect sizes were obtained for anxiety (GAD-7), depression (PHQ-9), and worry (PSWQ) (d=.90-2.54), and a moderate effect size was obtained for quality of life (WASA; d=.74). Recovery was indicated for 74% of cases for anxiety, 78% for depression, and 53% for worry. These findings exceeded most previous effectiveness studies in routine care and were in-line with GAD efficacy trials. This paper also outlines the application of specific clinical techniques selected, adapted or developed to target key cognitive mechanisms which maintain worry in GAD.

Modeling the Relationships Between Metacognitive Beliefs, Attention Control and Symptoms in Children With and Without Anxiety Disorders: A Test of the S-REF Model

In the metacognitive model, attentional control and metacognitive beliefs are key transdiagnostic mechanisms contributing to psychological disorder. The aim of the current study was to investigate the relative contribution of these mechanisms to symptoms of anxiety and depression in children with anxiety disorders and in non-clinical controls. In a cross-sectional design, 351 children (169 children diagnosed with a primary anxiety disorder and 182 community children) between 7 and 14 years of age completed self-report measures of symptoms, attention control and metacognitive beliefs. Clinically anxious children reported significantly higher levels of anxiety, lower levels of attention control and higher levels of maladaptive metacognitive beliefs than controls. Across groups, lower attention control and higher levels of maladaptive metacognitive beliefs were associated with stronger symptoms, and metacognitions were negatively associated with attention control. Domains of attention control and metacognitions explained unique variance in symptoms when these were entered in the same model within groups, and an interaction effect between metacognitions and attention control was found in the community group that explained additional variance in symptoms. In conclusion, the findings are consistent with predictions of the metacognitive model; metacognitive beliefs and individual differences in self-report attention control both contributed to psychological dysfunction in children and metacognitive beliefs appeared to be the strongest factor.

Control Conditions That Are Neither Usual Care Nor No Treatment in Randomized Trials of Psychoeducational Palliative Care Interventions: A Systematic Review

BACKGROUND:

Determining intervention efficacy depends as much on the control group as on the intervention, but little attention has been given to the control condition in psychoeducational trials in palliative care.

OBJECTIVES:

To examine (1) research practice regarding control conditions that are neither usual care nor no-treatment controls in randomized trials of psychoeducational palliative care interventions and (2) the rationale and completeness of the descriptions of control conditions in trial reports.

METHODS:

PubMed, EMBASE, PsycINFO, and Web of Science were searched. After screening 1603 articles, 70 full-text articles were assessed for eligibility. The final sample included 9 trial reports. We used the Delphi list for quality assessment and the modified intervention taxonomy checklist to assess active intervention and control conditions.

RESULTS:

Four trials used an attention control designed to be equivalent to the structure of the active intervention. In another 4, the control condition included some aspects of attention control such that the mode of contact was similar to that in the active intervention, but either the amount or the intensity of attention was not similar. Only 3 trial reports explicitly stated the rationale for the choice of control condition. Although most reports contained delivery mode, materials, duration, frequency, and sequence, none described the qualifications or training required to deliver the control condition. Only 1 report mentioned the fidelity monitoring method, and none included fidelity data.

CONCLUSION:

Our review of psychoeducational trials in palliative care calls for researchers' attention to appropriate selection, design, conduct and report of control conditions.

Delay of gratification in preschoolers with and without autism spectrum disorder: Individual differences and links to executive function, emotion regulation, and joint attention

This study examined delay of gratification behaviors in preschool-aged children with and without autism spectrum disorder. Recent research has found that elementary-aged children with autism spectrum disorder showed challenges with delay of gratification and that there were individual differences in terms of children's behaviors during the wait. We extend this work to a younger sample of children with autism spectrum disorder to understand whether these difficulties emerge by the preschool years. Moreover, we assessed whether individual differences in other key self-regulatory capacities (i.e. effortful control, emotion regulation, executive function, and joint attention) were related to delay of gratification wait durations or behavioral strategies. Findings revealed that preschoolers with autism spectrum disorder waited for a shorter duration, demonstrated more temptation-focused behaviors, and expressed less positive affect than their typical peers during the delay of gratification task. At the full-sample level, individual differences in children's temptation-focused behaviors (i.e. visual attention and verbalizations focused on the temptation) were related to children's executive function, joint attention, and parents' ratings of emotion regulation. When we examined associations within groups, the associations were not significant for the autism spectrum disorder group, but for typically developing children, there was a positive association between temptation-focused behaviors and emotion regulation.

Does Change in Attention Control Mediate the Impact of tDCS on Attentional Bias for Threat? Limited Evidence from a Double-blind Sham-controlled Experiment in an Unselected Sample

Neurocognitive models of attentional bias for threat posit that attentional bias may result from a decreased activation of the left prefrontal cortex, and especially of its dorsolateral part (dlPFC), resulting in an impaired attention control. Consequently, a transient increase of neural activity within the left dlPFC via non-invasive brain stimulation reduces attentional bias among both anxious and nonanxious participants. Yet, it is still unclear whether the impact of dlPFC activation on attentional bias is mediated by improvement in attention control. In this experiment, we sought to test this hypothesis in an unselected sample (n = 20). Accordingly, we adopted a double-blind within-subject protocol in which we delivered a single-session of anodal versus sham transcranial Direct Current Stimulation (tDCS) over the left dlPFC during the completion of a task assessing attention control. We also assessed its subsequent impact on attentional bias. Neither attention control nor attentional bias did significantly improve following anodal tDCS. Although our results do not support our main hypothesis, we believe the present null results to be particularly useful for future meta-research in the field. We also formulated a series of methodological recommendations for future research aiming at testing the tDCS-induced modification of attentional bias.

Visuospatial working memory, auditory discrimination, and attention

The present study examined the degree to which tests of visuospatial storage capacity tap into domain-general storage and attention processes. This was done by comparing performance of visuospatial memory tasks with performance on sound-based sensory discrimination tasks. We found that memory task- and discrimination task performance both tapped into a cross-modality factor (visual and auditory). We further examined the degree to which this common variance could be explained by attention control and sustained attention. These attention factors accounted for roughly 60% of the variance in memory. This indicates that tests of visuospatial memory capacity reflect more than modality-specific memory.

Ego Depletion Reduces Attention Control: Evidence From Two High-Powered Preregistered Experiments

Two preregistered experiments with more than 1,000 participants in total found evidence of an ego depletion effect on attention control. Participants who exercised self-control on a writing task went on to make more errors on Stroop tasks (Experiment 1) and the Attention Network Test (Experiment 2) compared with participants who did not exercise self-control on the initial writing task. The depletion effect on response times was nonsignificant. A mini meta-analysis of the two experiments found a small ( d = 0.20) but significant increase in error rates in the controlled writing condition, thereby providing evidence of poorer attention control under ego depletion. These results, which emerged from preregistered experiments in large samples of participants, represent some of the most rigorous evidence yet of the ego depletion effect.

Essential considerations in developing attention control groups in behavioral research

Attention control groups strengthen randomized controlled trials of behavioral interventions, but researchers need to give careful consideration to the attention control activities. A comparative effectiveness research framework provides an ideal opportunity for an attention control group as a supplement to standard care, so participants potentially receive benefit regardless of group assignment. The anticipated benefit of the control condition must be independent of the study outcome. Resources needed for attention control activities need to be carefully considered and ethical considerations carefully weighed. In this paper we address nine considerations for the design and implementation of attention control groups: (1) ensure attention control activities are not associated with the outcome; (2) avoid contamination of the intervention or control group; (3) design comparable control and intervention activities; (4) ensure researcher training to adequately administer both treatment arms; (5) design control activities to be interesting and acceptable to participants; (6) evaluate attention control activities; (7) consider additional resources needed to implement attention control activities; (8) quantifying the effects of attention control and intervention groups; and (9) ethical considerations with attention control groups. Examples from the literature and ongoing research are presented. Careful planning for the attention control group is as important as for the intervention group. Researchers can use the considerations presented here to assist in planning for the best attention control group for their study.

Exercise modulates the interaction between cognition and anxiety in humans

Despite interest in exercise as a treatment for anxiety disorders the mechanism behind the anxiolytic effects of exercise is unclear. Two observations motivate the present work. First, engagement of attention control during increased working memory (WM) load can decrease anxiety. Second, exercise can improve attention control. Therefore, exercise could boost the anxiolytic effects of increased WM load via its strengthening of attention control. Anxiety was induced by threat of shock and was quantified with anxiety-potentiated startle (APS). Thirty-five healthy volunteers (19 male, age M = 26.11, SD  = 5.52) participated in two types of activity, exercise (biking at 60-70% of heart rate reserve) and control-activity (biking at 10-20% of heart rate reserve). After each activity, participants completed a WM task (n-back) at low- and high-load during safe and threat. Results were not consistent with the hypothesis: exercise vs. control-activity increased APS in high-load (p = .03). However, this increased APS was not accompanied with threat-induced impairment in WM performance (p = .37). Facilitation of both task-relevant stimulus processing and task-irrelevant threat processing, concurrent with prevention of threat interference on cognition, suggests that exercise increases cognitive ability. Future studies should explore how exercise affects the interplay of cognition and anxiety in patients with anxiety disorders.

Working memory capacity and the antisaccade task: A microanalytic-macroanalytic investigation of individual differences in goal activation and maintenance

The association between working memory capacity (WMC) and the antisaccade task, which requires subjects to move their eyes and attention away from a strong visual cue, supports the claim that WMC is partially an attentional construct (Kane, Bleckley, Conway, & Engle, 2001; Unsworth, Schrock, & Engle, 2004). Specifically, the WMC-antisaccade relation suggests that WMC helps maintain and execute task goals despite interference from habitual actions. Related work has recently shown that mind wandering (McVay & Kane, 2009, 2012a, 2012b) and reaction time (RT) variability (Unsworth, 2015) are also related to WMC and they partially explain WMC's prediction of cognitive abilities. Here, we tested whether mind-wandering propensity and intraindividual RT variation account for WMC's associations with 2 antisaccade-cued choice RT tasks. In addition, we asked whether any influences of WMC, mind wandering, or intraindividual RT variation on antisaccade are moderated by (a) the temporal gap between fixation and the flashing location cue, and (b) whether targets switch sides on consecutive trials. Our quasi-experimental study reexamined a published dataset (Kane et al., 2016) comprising 472 subjects who completed 6 WMC tasks, 5 attentional tasks with mind-wandering probes, 5 tasks from which we measured intraindividual RT variation, and 2 antisaccade tasks with varying fixation-cue gap durations. The WMC-antisaccade association was not accounted for by mind wandering or intraindividual RT variation. WMC's effects on antisaccade performance were greater with longer fixation-to-cue intervals, suggesting that goal activation processes-beyond the ability to control mind wandering and RT variability-are partially responsible for the WMC-antisaccade relation.

Reluctance to express emotion explains relation between cognitive distortions and social competence in anxious children

Guided by social information processing and affective social competence models, the focal objective of this research was to examine the relations among anxious children's cognitive distortions, social skill competence, and reluctance to express emotion. In addition, we explored whether children's attention control played any meaningful role. Using a sample of 111 anxious children (M_age  = 9.63, SD = 0.73; 75.7% girls; 56% Hispanic/Latino), we found that cognitive distortions were negatively related to social competence. In addition, tests of moderated mediation showed that the negative association between cognitive distortions and social skill competence was indirect via reluctance to express emotion, but this only was the case for anxious children with high attention control and for distortions in the academic domain. The findings of this study may set the stage for new ways to conceptualize the role of higher attention control among anxious youth. Statement of contribution What is already known on this subject? Cognitive errors are prevalent in anxious youth Anxious children show socio-emotion deficits What does this study add? Cognitive errors are related to socio-emotion deficits in anxious youth Relations depend on attention control.

Switching to the Rubber Hand

Inducing the rubber hand illusion (RHI) requires that participants look at an imitation hand while it is stroked in synchrony with their occluded biological hand. Previous explanations of the RHI have emphasized multisensory integration, and excluded higher cognitive functions. We investigated the relationship between the RHI and higher cognitive functions by experimentally testing task switch (as measured by switch cost) and mind wandering (as measured by SART score); we also included a questionnaire for attentional control that comprises two subscales, attention-shift and attention-focus. To assess experience of RHI, the Botvinick and Cohen (1998) questionnaire was used and illusion onset time was recorded. Our results indicate that rapidity of onset reliably indicates illusion strength. Regression analysis revealed that participants evincing less switch cost and higher attention-shift scores had faster RHI onset times, and that those with higher attention-shift scores experienced the RHI more vividly. These results suggest that the multi-sensory hypothesis is not sufficient to explain the illusion: higher cognitive functions should be taken into account when explaining variation in the experience of ownership for the rubber hand.

Working Memory Capacity and Fluid Intelligence: Maintenance and Disengagement

Working memory capacity and fluid intelligence have been demonstrated to be strongly correlated traits. Typically, high working memory capacity is believed to facilitate reasoning through accurate maintenance of relevant information. In this article, we present a proposal reframing this issue, such that tests of working memory capacity and fluid intelligence are seen as measuring complementary processes that facilitate complex cognition. Respectively, these are the ability to maintain access to critical information and the ability to disengage from or block outdated information. In the realm of problem solving, high working memory capacity allows a person to represent and maintain a problem accurately and stably, so that hypothesis testing can be conducted. However, as hypotheses are disproven or become untenable, disengaging from outdated problem solving attempts becomes important so that new hypotheses can be generated and tested. From this perspective, the strong correlation between working memory capacity and fluid intelligence is due not to one ability having a causal influence on the other but to separate attention-demanding mental functions that can be contrary to one another but are organized around top-down processing goals.

Amplitude of Sensorimotor Mu Rhythm Is Correlated with BOLD from Multiple Brain Regions: A Simultaneous EEG-fMRI Study

The mu rhythm is a field oscillation in the ∼10Hz range over the sensorimotor cortex. For decades, the suppression of mu (event-related desynchronization) has been used to index movement planning, execution, and imagery. Recent work reports that non-motor processes, such as spatial attention and movement observation, also desynchronize mu, raising the possibility that the mu rhythm is associated with the activity of multiple brain regions and systems. In this study, we tested this hypothesis by recording simultaneous resting-state EEG-fMRI from healthy subjects. Independent component analysis (ICA) was applied to extract the mu components. The amplitude (power) fluctuations of mu were estimated as a time series using a moving-window approach, which, after convolving with a canonical hemodynamic response function (HRF), was correlated with blood-oxygen-level-dependent (BOLD) signals from the entire brain. Two main results were found. First, mu power was negatively correlated with BOLD from areas of the sensorimotor network, the attention control network, the putative mirror neuron system, and the network thought to support theory of mind. Second, mu power was positively correlated with BOLD from areas of the salience network, including anterior cingulate cortex and anterior insula. These results are consistent with the hypothesis that sensorimotor mu rhythm is associated with multiple brain regions and systems. They also suggest that caution should be exercised when attempting to interpret mu modulation in terms of a single brain network.

Effects of a Responsiveness-Focused Intervention in Family Child Care Homes on Children's Executive Function

Caregiver responsiveness has been theorized and found to support children's early executive function (EF) development. This study examined the effects of an intervention that targeted family child care provider responsiveness on children's EF. Family child care providers were randomly assigned to one of two intervention groups or a control group. An intervention group that received a responsiveness-focused online professional development course and another intervention group that received this online course plus weekly mentoring were collapsed into one group because they did not differ on any of the outcome variables. Children (N = 141) ranged in age from 2.5 to 5 years (mean age = 3.58 years; 52% female). At pretest and posttest, children completed delay inhibition tasks (gift delay-wrap, gift delay-bow) and conflict EF tasks (bear/dragon, dimensional change card sort), and parents reported on the children's level of attention problems. Although there were no main effects of the intervention on children's EF, there were significant interactions between intervention status and child age for delay inhibition and attention problems. The youngest children improved in delay inhibition and attention problems if they were in the intervention rather than the control group, whereas older children did not. These results suggest that improving family child care provider responsive behaviors may facilitate the development of certain EF skills in young preschool-age children.

Frontopolar Resource Allocation in Human and Nonhuman Primates

A recent report suggested that monkey frontopolar cortex (FPC) is vital for the reallocation of cognitive resources among potential goals in complex underspecified situations. These findings nicely complement evidence from human neuroimaging and patient studies, leading to a common conceptual framework of FPC function across species.

Caspase-3 deficiency results in disrupted synaptic homeostasis and impaired attention control

The ability to attend to relevant stimuli and to adapt dynamically as demands change is a core aspect of cognition, and one that is impaired in several neuropsychiatric diseases, including attention deficit/hyperactivity disorder. However, the cellular and molecular mechanisms underlying such cognitive adaptability are poorly understood. We found that deletion of the caspase-3 gene, encoding an apoptosis protease with newly discovered roles in neural plasticity, disrupts attention in mice while preserving multiple learning and memory capabilities. Attention-related deficits include distractibility, impulsivity, behavioral rigidity, and reduced habituation to novel stimuli. Excess exploratory activity in Casp3(-/-) mice was correlated with enhanced novelty-induced activity in the dentate gyrus, which may be related to our findings that caspase-3 is required for homeostatic synaptic plasticity in vitro and homeostatic expression of AMPA receptors in vivo in response to chronic or repeated stimuli. These results suggest an important role for caspase-3 in synaptic suppression of irrelevant stimuli.

Reading performance is predicted by more than phonological processing

We compared three phonological processing components (phonological awareness, rapid automatized naming and phonological memory), verbal working memory, and attention control in terms of how well they predict the various aspects of reading: word recognition, pseudoword decoding, fluency and comprehension, in a mixed sample of 182 children ages 8–12 years. Participants displayed a wide range of reading ability and attention control. Multiple regression was used to determine how well the phonological processing components, verbal working memory, and attention control predict reading performance. All equations were highly significant. Phonological memory predicted word identification and decoding. In addition, phonological awareness and rapid automatized naming predicted every aspect of reading assessed, supporting the notion that phonological processing is a core contributor to reading ability. Nonetheless, phonological processing was not the only predictor of reading performance. Verbal working memory predicted fluency, decoding and comprehension, and attention control predicted fluency. Based upon our results, when using Baddeley’s model of working memory it appears that the phonological loop contributes to basic reading ability, whereas the central executive contributes to fluency and comprehension, along with decoding. Attention control was of interest as some children with ADHD have poor reading ability even if it is not sufficiently impaired to warrant diagnosis. Our finding that attention control predicts reading fluency is consistent with prior research which showed sustained attention plays a role in fluency. Taken together, our results suggest that reading is a highly complex skill that entails more than phonological processing to perform well.
