Abstract
Nonhuman primates (NHPs) are an essential research model for gaining a comprehensive understanding of the neural mechanisms of neurocognitive aging in our own species. In the present study, we used resting state functional connectivity (rsFC) to investigate the relationship between prefrontal cortical and striatal neural interactions, and cognitive flexibility, in unanaesthetized common marmosets (Callithrix jacchus) at two time points during late middle age (8 months apart, similar to a span of 5-6 years in humans). Based on our previous findings, we also determine the reproducibility of connectivity measures over the course of 8 months, particularly previously observed sex differences in rsFC. Male marmosets exhibited remarkably similar patterns of stronger functional connectivity relative to females and greater cognitive flexibility between the two imaging time points. Network analysis revealed that the consistent sex differences in connectivity and related cognitive associations were characterized by greater node strength and/or degree values in several prefrontal, premotor and temporal regions, as well as stronger intra PFC connectivity, in males compared to females. The current study supports the existence of robust sex differences in prefrontal and striatal resting state networks that may contribute to differences in cognitive function and offers insight on the neural systems that may be compromised in cognitive aging and age-related conditions such as mild cognitive impairment and Alzheimer's disease.

A Neurally Inspired Model of Figure Ground Organization with Local and Global Cues. AI 2020.

Abstract
Figure Ground Organization (FGO)-inferring spatial depth ordering of objects in a visual scene-involves determining which side of an occlusion boundary is figure (closer to the observer) and which is ground (further away from the observer). A combination of global cues, like convexity, and local cues, like T-junctions are involved in this process. A biologically motivated, feed forward computational model of FGO incorporating convexity, surroundedness, parallelism as global cues and spectral anisotropy (SA), T-junctions as local cues is presented. While SA is computed in a biologically plausible manner, the inclusion of T-Junctions is biologically motivated. The model consists of three independent feature channels, Color, Intensity and Orientation, but SA and T-Junctions are introduced only in the Orientation channel as these properties are specific to that feature of objects. The effect of adding each local cue independently and both of them simultaneously to the model with no local cues is studied. Model performance is evaluated based on figure-ground classification accuracy (FGCA) at every border location using the BSDS 300 figure-ground dataset. Each local cue, when added alone, gives statistically significant improvement in the FGCA of the model suggesting its usefulness as an independent FGO cue. The model with both local cues achieves higher FGCA than the models with individual cues, indicating SA and T-Junctions are not mutually contradictory. Compared to the model with no local cues, the feed-forward model with both local cues achieves ≥8.78% improvement in terms of FGCA.

Abstract
A frequent observation in dual-task experiments is that performance in Task 1 is influenced by conceptual or spatial overlap with features of Task 2. Such compatibility-based backward crosstalk effects (BCEs) can occur when overlap exists between the responses of two tasks-the R1-R2 BCE-or between the stimulus in Task 1 and the response in Task 2-the S1-R2 BCE. The present study investigated whether the S1-R2 BCE has a perceptual locus, and by implication, whether the two BCEs have a common processing locus or different ones. To this end, we applied the additive factors logic and manipulated the duration of the Task 1 perceptual stage. The results argue against a perceptual locus for both BCEs. As a possible explanation, we suggest that the R1-R2 BCE and the S1-R2 BCE have their locus within a capacity-limited central stage, but that they arise from different processes within this stage. The R1-R2 BCE influences Task 1 response selection, whereas the S1-R2 BCE influences Task 1 stimulus classification. A plausible though post-hoc model is presented within the Discussion.

Abstract
OBJECTIVE The question whether children with DCD have motor learning deficits is difficult to answer based on the current body of knowledge. The aim of this study was to examine the impact of practice on motor skill acquisition, retention and transfer in children with and without DCD using a variety of games in a virtual environment. METHOD Performance on a criterion task (Wii ski game) and MABC-2 balance subscore was compared between children with DCD (n = 33) and TD children (n = 28) following 10 weeks of playing active video games. Repeated measures ANOVA was used to compare changes in the two groups. RESULTS The children with DCD demonstrated lower performance on the criterion task than the TD group (p = 0.031). A time by group interaction indicated that the difference in performance on the criterion task became larger over time (p = 0.039). No differences were found in retention between groups. Large improvement (Cohen d 1.11) was observed for the children with DCD on the MABC-2 balance subscore. CONCLUSION Based on the criterion task results, typically developing children seem more proficient in learning new skills compared to children with DCD. More research is needed to confirm that children with DCD have a problem to transfer skills to other contexts.

Abstract
Researchers have debated the extent to which the experience of speaking more than two languages induces long-term neuroplasticity that protects multilinguals from the adverse cognitive effects of aging. In this review, I propose a novel theory that multilingualism affects cognitive persistence, the application of effort to improve performance on challenging tasks. I review recent evidence demonstrating that the cingulo-opercular network, consisting of the bilateral inferior frontal gyrus (IFG) and dorsal anterior cingulate cortex (dACC), supports cognitive persistence. I then show that this same network is involved in multilingual language control and changes with multilingual language experience. While both early and late multilinguals exhibit differences in the cingulo-opercular network compared to monolinguals, I find that early multilinguals have a pattern of decreased dACC activity and increased left IFG activity that may enable more efficient cognitive control, whereas late multilinguals show larger dACC responses to conflict that may be associated with higher cognitive persistence. I further demonstrate that multilingual effects on the cingulo-opercular network are present in older adults and have been implicated in the mitigation of cognitive symptoms in age-related neurodegenerative disorders. Finally, I argue that mixed results in the literature are due, in part, to the confound between cognitive persistence and ability in most executive function tasks, and I provide guidance for separating these processes in future research.

Abstract
Objective Previous studies suggest that daily music listening can aid stroke recovery, but little is known about the stimulus‐dependent and neural mechanisms driving this effect. Building on neuroimaging evidence that vocal music engages extensive and bilateral networks in the brain, we sought to determine if it would be more effective for enhancing cognitive and language recovery and neuroplasticity than instrumental music or speech after stroke. Methods Using data pooled from two single‐blind randomized controlled trials in stroke patients (N = 83), we compared the effects of daily listening to self‐selected vocal music, instrumental music, and audiobooks during the first 3 poststroke months. Outcome measures comprised neuropsychological tests of verbal memory (primary outcome), language, and attention and a mood questionnaire performed at acute, 3‐month, and 6‐month stages and structural and functional MRI at acute and 6‐month stages. Results Listening to vocal music enhanced verbal memory recovery more than instrumental music or audiobooks and language recovery more than audiobooks, especially in aphasic patients. Voxel‐based morphometry and resting‐state and task‐based fMRI results showed that vocal music listening selectively increased gray matter volume in left temporal areas and functional connectivity in the default mode network. Interpretation Vocal music listening is an effective and easily applicable tool to support cognitive recovery after stroke as well as to enhance early language recovery in aphasia. The rehabilitative effects of vocal music are driven by both structural and functional plasticity changes in temporoparietal networks crucial for emotional processing, language, and memory.

Abstract
The ability to recognise places is known to deteriorate with advancing age. In this study, we investigated the contribution of age-related changes in spatial encoding strategies to declining place recognition ability. We recorded eye movements while younger and older adults completed a place recognition task first described by Muffato et al. (2019). Participants first learned places, which were defined by an array of four objects, and then decided whether the next place they were shown was the same or different to the one they learned. Places could be shown from the same spatial perspective as during learning or from a shifted perspective (30° or 60°). Places that were different to those during learning were changed either by substituting an object in the place with a novel object or by swapping the locations of two objects. We replicated the findings of Muffato et al. (2019) showing that sensitivity to detect changes in a place declined with advancing age and declined when the spatial perspective was shifted. Additionally, older adults were particularly impaired on trials in which object locations were swapped; however, they were not differentially affected by perspective changes compared to younger adults. During place encoding, older adults produced more fixations and saccades, shorter fixation durations, and spent less time looking at objects compared to younger adults. Further, we present an analysis of gaze chaining, designed to capture spatio-temporal aspects of gaze behaviour. The chaining measure was a significant predictor of place recognition performance. We found significant differences between age groups on the chaining measure and argue that these differences in gaze behaviour are indicative of differences in encoding strategy between age groups. In summary, we report a direct replication of Muffato et al. (2019) and provide evidence for age-related differences in spatial encoding strategies, which are related to place recognition performance.

Abstract
Although interpersonal trauma history (ITH) is frequently associated with alcohol use disorder (AUD), little is known about specific psychological constructs that may indirectly link these phenomena. This study hypothesized that one such construct may be negative cognitive schemas that often emerge in the aftermath of trauma. Secondary latent variable modeling was conducted using the Project MATCH sample of adults receiving treatment for AUD (N = 1726; 24.3% women; 38.63% ITH). The negative cognitions latent variable provided an excellent fit to the data and showed evidence of strong measurement invariance. As hypothesized, negative cognitions mediated the inverse association between ITH at baseline and percent days abstinent from alcohol 12 weeks later. Findings suggest that negative cognitions may be a specific underlying mechanism and potential treatment target for individuals with ITH and AUD.

Abstract
Introduction Technological advances have allowed for the estimation of physiological indicators from video data. FaceReader™ is an automated facial analysis software that has been used widely in studies of facial expressions of emotion and was recently updated to allow for the estimation of heart rate (HR) using remote photoplethysmography (rPPG). We investigated FaceReader™-based heart rate and pain expression estimations in older adults in relation to manual coding by experts. Methods Using a video dataset of older adult patients with and without dementia, we assessed the relationship between FaceReader’s™ HR estimations against a well-established Video Magnification (VM) algorithm during baseline and pain conditions. Furthermore, we examined the correspondence between the Facial Action Coding System (FACS)-based pain scores obtained through FaceReader™ and manual coding. Results FaceReader’s™ HR estimations were correlated with VM algorithm in baseline and pain conditions. Non-verbal FaceReader™ pain scores and manual coding were also highly correlated despite discrepancies between the FaceReader™ and manual coding in the absolute value of scores based on pain-related facial action coding of the events preceding and following the pain response. Conclusions Compared to expert manual FACS coding and optimized VM algorithm, FaceReader™ showed good results in estimating HR values and non-verbal pain scores.

Abstract
Objective Cognitive remediation (CR) techniques (interventions to enhance cognitive functioning) have proven moderately effective in improving cognition and daily functioning in major depressive disorder (MDD). However, baseline predictors of treatment response are lacking. The present study aimed to identify factors influencing long-term CR outcomes in a sample with current or previous, mild or moderate MDD and with self-reported cognitive deficits. Methods Forty-two completers of group-based CR (strategy learning or drill-and-practice), were pooled into one sample. Based on change scores from baseline to 6-month follow-up, participants were categorized as “improvers” or “non-improvers” using reliable change index calculations. Measures included a questionnaire of everyday executive functioning and a neuropsychological test of attention. Finally, improvers and non-improvers were compared in terms of various sociodemographic, psychological, illness-related, and neuropsychological baseline variables. Results Seventeen participants improved reliably in everyday executive functioning, and fourteen demonstrated a reliable improvement in attention. No statistically significant differences emerged between improvers and non-improvers. Conclusion No major predictors of CR were identified. Importantly, the current findings are insufficient to guide clinical decision-making. Large-scale studies with a priori hypotheses are needed to make advances in the future.

Abstract
Thanks to the work of Anne Treisman and many others, the visual search paradigm has become one of the most popular paradigms in the study of visual attention. However, statistics like mean correct response time (RT) and percent error do not usually suffice to decide between the different search models that have been developed. Recently, to move beyond mean performance measures in visual search, RT histograms have been plotted, theoretical waiting time distributions have been fitted, and whole RT and error distributions have been simulated. Here we promote and illustrate the general application of discrete-time hazard analysis to response times, and of micro-level speed-accuracy tradeoff analysis to timed response accuracies. An exploratory analysis of published benchmark search data from feature, conjunction, and spatial configuration search tasks reveals new features of visual search behavior, such as a relatively flat hazard function in the right tail of the RT distributions for all tasks, a clear effect of set size on the shape of the RT distribution for the feature search task, and individual differences in the presence of a systematic pattern of early errors. Our findings suggest that the temporal dynamics of visual search behavior results from a decision process that is temporally modulated by concurrently active recurrent object recognition, learning, and cognitive control processes, next to attentional selection processes.

Abstract
Online quizzes building upon the principles of retrieval practice can have beneficial effects on learning, especially long-term retention. However, it is unexplored how interindividual differences in relevant background characteristics relate to retrieval practice activities in e-learning. Thus, this study sought to probe for this research question on a massive open online course (MOOC) platform where students have the optional possibility to quiz themselves on the to-be-learned materials. Altogether 105 students were assessed with a cognitive task tapping on reasoning, and two self-assessed personality measures capturing need for cognition (NFC), and grittiness (GRIT-S). Between-group analyses revealed that cognitively high performing individuals were more likely to use the optional quizzes on the platform. Moreover, within-group analyses (n = 56) including those students using the optional quizzes on the platform showed that reasoning significantly predicted quiz performance, and quiz processing speed. NFC and GRIT-S were unrelated to each of the aforementioned retrieval practice activities.

Visual and central attention share a capacity limitation when the demands for serial item selection in visual search are high. Atten Percept Psychophys 2020; 82:715-728.

Abstract
Visual and central attention are limited in capacity. In conjunction search, visual attention is required to select the items and to bind their features (e.g., color, form, size), which results in a serial search process. In dual-tasks, central attention is required for response selection, but because central attention is limited in capacity, response selection can only be carried out for one task at a time. Here, we investigated whether visual and central attention rely on a common or on distinct capacity limitations. In two dual-task experiments, participants completed an auditory two-choice discrimination Task 1 and a conjunction search Task 2 that were presented with an experimentally modulated temporal interval between them (stimulus onset asynchrony [SOA]). In Experiment 1, Task 2 was a triple conjunction search task. Each item consisted of a conjunction of three features, so that target and distractors shared two features. In Experiment 2, Task 2 was a plus conjunction search task, in which target and distractors shared the same four features. The hypotheses for conjunction search time were derived from the locus-of-slack method. While plus conjunction search was performed after response selection in Task 1, a small part of triple conjunction search was still performed in parallel to response selection in Task 1. However, the between-experiment comparison was not significant, indicating that both search tasks may require central attention. Taken together, the present study provides evidence that visual and central attention share a common capacity limitation when conjunction search relies strongly on serial item selection.

A new data-driven mathematical model dissociates attractiveness from sexual dimorphism of human faces. Sci Rep 2020; 10:16588.

Abstract
Human facial attractiveness is evaluated by using multiple cues. Among others, sexual dimorphism (i.e. masculinity for male faces/femininity for female faces) is an influential factor of perceived attractiveness. Since facial attractiveness is judged by incorporating sexually dimorphic traits as well as other cues, it is theoretically possible to dissociate sexual dimorphism from facial attractiveness. This study tested this by using a data-driven mathematical modelling approach. We first analysed the correlation between perceived masculinity/femininity and attractiveness ratings for 400 computer-generated male and female faces (Experiment 1) and found positive correlations between perceived femininity and attractiveness for both male and female faces. Using these results, we manipulated a set of faces along the attractiveness dimension while controlling for sexual dimorphism by orthogonalisation with data-driven mathematical models (Experiment 2). Our results revealed that perceived attractiveness and sexual dimorphism are dissociable, suggesting that there are as yet unidentified facial cues other than sexual dimorphism that contribute to facial attractiveness. Future studies can investigate the true preference of sexual dimorphism or the genuine effects of attractiveness by using well-controlled facial stimuli like those that this study generated. The findings will be of benefit to the further understanding of what makes a face attractive.

Abstract
Over the years, researchers have enriched the postulation that hedonic products generate deeper emotional reactions and feelings in the consumer than functional products. However, recent research empirically proves that hedonic products are more affect-rich only for some consumer segments or for specific consumption contexts. We argue that such inconsistency may derive from the nature of the emotions assessed that is strictly dependent on their empirical measurement and not from the mere existence of emotions themselves. Self-reported methods of evaluating consumer experience, on which prior studies are grounded, only assess conscious emotions the consumer can recognize and report, but not unconscious feelings, happening without individual awareness. The present work takes this challenge by conducting a laboratory experiment in which subjects are exposed to both a utilitarian product and a hedonic product. Physiological measures have been adopted to investigate unconscious emotional responses and self-reported measures to assess conscious emotions toward the products. Specifically, physiological data regarding the subjects’ cardiac activity, respiratory activity, electrodermal activity, and cerebral activity have been collected and complemented with a survey. Results confirm that both functional and hedonic products generate emotional responses in consumers. Further, findings show that when a consumer is exposed to a functional product, the physiological emotional responses are disassociated from the self-reported ones. A diverse pattern is depicted for hedonic products. We suggest an alternative explanation for the apparent lack of affect-rich experiences elicited by functional products and the need to reconsider emotional responses for these products.

Abstract
OBJECTIVE To analyze prevalence of venous thromboembolism (VTE) after ultrasound guided foam sclerotherapy. METHOD Clinical retrospective study with patients treated from 2004 to 2014. Charts with incomplete data and follow-up less than 60 days were excluded. Polidocanol foam (Tessari method) was used. The primary outcome was the prevalence of VTE and the secondary were possible risk factors. Chi-square test and Marascuillo prodecure were applied at a significance level of 5%. RESULTS 2,616 patients were included with 4,712 lower limbs treated. The mean age was 50.7±0.86, in majority female, 83.7%. VTE occurred in 0.49% (pulmonary embolism 0,3%) in a mean time of 44.0±42.2 days. Male gender, personal or family history of phlebitis or DVT and high caliber varicose veins were significantly associated to VTE. CONCLUSION incidence of VTE is low, male gender, personal or family history of VTE and caliber of varicose veins greater than 7 mm increased the risk.

Abstract
Several studies have tried to establish the factors that underlie mathematical ability across development. Among them, spatial and motor abilities might play a relevant role, but no studies jointly contemplate both types of abilities to account for mathematical performance. The present study was designed to observe the roles of spatial and motor skills in mathematical performance. A total of 305 children aged between 6 and 8 years took part in this study. A generalized linear regression model with mathematical performance as a dependent variable was performed. Results revealed that Block design (as a visuospatial reasoning measure) accounted for mathematical performance, especially among 6- and 7-year-olds but not in 8-year-olds. After controlling for the effect of the block design, mental rotation and manual dexterity predicted mathematical performance. These findings highlight the role of underlying cognitive (spatial) and motor abilities in supporting mathematical achievement in primary school children.

Abstract
Three studies demonstrated that situational uncertainty impairs executive function on subsequent unrelated tasks. Participants were randomly assigned to either uncertain situations (not knowing whether they would have to give a speech later, Studies 1-2; uncertain about how to complete a task, Study 3) or control conditions. Uncertainty caused poor performance on tasks requiring executive function that were unrelated to the uncertainty manipulation. Uncertainty impaired performance even more than certainty of negative outcomes (might vs. definitely will have to make a speech). A meta-analysis of the experimental studies in this package found that the effect is small and reliable. One potential explanation for this effect of uncertainty on executive function is that uncertainty is a cue for conserving effort.

Abstract
BACKGROUND Subjective well-being (SWB) is an important indicator of quality of life, but prior research mostly analyzed adolescents' subjective well-being in cross-sectional studies. There is a lack of studies examining changes in subjective well-being throughout adolescence using longitudinal panel data. This study examined trajectories of subjective well-being of adolescents in Germany throughout secondary education and differences by socioeconomic position, gender and family structure. METHODS We use the German National Educational Panel Study and combine data from annual survey waves of two of its cohorts. These were first surveyed in 2010 and cover 5th to 10th and 9th to 12th grade level. Using growth curve modelling based on multilevel models, differences in levels and trajectories of subjective well-being overall and differentiated by school type, parental education, household income, gender and family structure were identified. The analyses include 34 504 observations of 12 564 students. RESULTS Subjective well-being decreased from 5th to 12th grade. Students attending lower track schools showed lower subjective well-being, but also a lesser decrease over time. Students living in low-income households or in single-parent or step-families showed lower subjective well-being. Female students showed higher subjective well-being than males in 5th grade, but also a higher decrease over time, leading to lower subjective well-being than males by 12th grade. CONCLUSION This study provides a comprehensive picture of subjective well-being throughout secondary education. Adolescents' subjective well-being is linked to social factors regarding family and living conditions as well as school features. Overall, disadvantaged adolescents experience longer periods of lower subjective well-being, thus accumulating the effects of worse psychosocial health opportunities over time.

Abstract
In Bayesian cognitive science, the mind is seen as a spectacular probabilistic-inference machine. But judgment and decision-making (JDM) researchers have spent half a century uncovering how dramatically and systematically people depart from rational norms. In this article, we outline recent research that opens up the possibility of an unexpected reconciliation. The key hypothesis is that the brain neither represents nor calculates with probabilities but approximates probabilistic calculations by drawing samples from memory or mental simulation. Sampling models diverge from perfect probabilistic calculations in ways that capture many classic JDM findings, which offers the hope of an integrated explanation of classic heuristics and biases, including availability, representativeness, and anchoring and adjustment.

Abstract
AIM The overarching objective of this report is to provide an updated definition of the concept of organizational climate and to strengthen its operational application. BACKGROUND Organizational climate is one of the major contributing factors to the exodus of the nursing workforce from the profession. Extensive research has addressed the impact of "organizational climate" on the nursing workforce; yet variations in the interpretation of the concept calls for an updated definition. DESIGN Walker and Avant's strategy was implemented. DATA SOURCE Data were compiled from Medline and CINAHL, Google search engine, and book chapters. REVIEW METHOD A comprehensive and detailed review of the literature was performed. Nineteen historic publications (1939-2012) and 39 healthcare-related publications (2013-2018) were included in the final review. RESULTS The climate of an organization reflects a set of core values and behaviors that can be used to implement evidence-based leadership and management within the context of the 21st century. We have revised the definition of organizational climate to capture this context. CONCLUSION The perception of a supportive and constructive climate in an organization propels the workforce, independent of ethnic or personal background, to a higher level of productivity and encourages loyalty and workforce stability.

Abstract
Causal judgments are widely known to be sensitive to violations of both prescriptive norms (e.g., immoral events) and statistical norms (e.g., improbable events). There is ongoing discussion as to whether both effects are best explained in a unified way through changes in the relevance of counterfactual possibilities, or whether these two effects arise from unrelated cognitive mechanisms. Recent work has shown that moral norm violations affect causal judgments of agents, but not inanimate artifacts used by those agents. These results have been interpreted as showing that prescriptive norm violations only affect causal reasoning about intentional agents, but not the use of inanimate artifacts, thereby providing evidence that the effect of prescriptive norm violations arises from mechanisms specific to reasoning about intentional agents, and thus casting doubt on a unified counterfactual analysis of causal reasoning. Four experiments explore this recent finding and provide clear support for a unified counterfactual analysis. Experiment 1 demonstrates that these newly observed patterns in causal judgments are closely mirrored by judgments of counterfactual relevance. Experiment 2 shows that the relationship between causal and counterfactual judgments is moderated by causal structure, as uniquely predicted by counterfactual accounts. Experiment 3 directly manipulates the relevance of counterfactual alternatives and finds that causal judgments of intentional agents and inanimate artifacts are similarly affected. Finally, Experiment 4 shows that prescriptive norm violations (in which artifacts malfunction) affect causal judgments of inanimate artifacts in much the same way that prescriptive norm violations (in which agents act immorally) affect causal judgments of intentional agents.

Abstract
AbstractTraumatic brain injury (TBI) is associated with a wide range of physiological, behavioral, emotional, and cognitive sequelae. Litigation status is one of the many factors that has an impact on recovery. The aim of this study was to compare executive functions, postconcussion, and depressive symptoms in TBI patients with and without litigation. A sample of 30 patients with TBI, 15 patients with litigation (medicolegal case [MLC]), and 15 without litigation (non-MLC) was assessed. The tools used were sociodemographic and clinical proforma, executive function tests, Rivermead Post-Concussion Symptom Questionnaire, and Beck Depression Inventory. Assessment revealed that more than 50% of patients showed deficits in category fluency, set shifting, and concept formation. The MLC group showed significant impairment on verbal working memory in comparison to the non-MLC group. The performance of both groups was comparable on tests of semantic fluency, visuospatial working memory, concept formation, set shifting, planning, and response inhibition. The MLC group showed more verbal working memory deficits in the absence of significant postconcussion and depressive symptoms on self-report measures.

Abstract
Researchers examining nonverbal communication of emotions are becoming increasingly interested in differentiations between different positive emotional states like interest, relief, and pride. But despite the importance of the voice in communicating emotion in general and positive emotion in particular, there is to date no systematic review of what characterizes vocal expressions of different positive emotions. Furthermore, integration and synthesis of current findings are lacking. In this review, we comprehensively review studies (N = 108) investigating acoustic features relating to specific positive emotions in speech prosody and nonverbal vocalizations. We find that happy voices are generally loud with considerable variability in loudness, have high and variable pitch, and are high in the first two formant frequencies. When specific positive emotions are directly compared with each other, pitch mean, loudness mean, and speech rate differ across positive emotions, with patterns mapping onto clusters of emotions, so-called emotion families. For instance, pitch is higher for epistemological emotions (amusement, interest, relief), moderate for savouring emotions (contentment and pleasure), and lower for a prosocial emotion (admiration). Some, but not all, of the differences in acoustic patterns also map on to differences in arousal levels. We end by pointing to limitations in extant work and making concrete proposals for future research on positive emotions in the voice.

Abstract
This paper reviews and critically assesses the implications of directed forgetting (DF) research on clinical populations. We begin by reviewing the typical methods and results of the item method and list method directed forgetting procedures and provide best practice recommendations for future studies using clinical populations. Next, we note that DF was often interpreted as being due to inhibition, and when clinical populations showed impaired directed forgetting, it was treated as evidence in inhibitory control difficulties. However, inhibition may not be the cause of DF effects, based on current understanding of these cognitive tasks. We instead suggest that item method DF is tied to attentional control, which might include inhibitory mechanisms (or might not). In contrast, list method DF is tied to two forms of memory control: control of mental context (indicated by effective forgetting of List 1), and changes in the strategies used to remember (indicated by better learning of List 2). We review the current state of the clinical DF literature, assess its strength based on our best practice recommendations, and call for more research when warranted.

Abstract
Prompted by rising concern about weak consumer switching and the practice of price discrimination, over the period of 2016–2019, the Office of Gas and Electricity Markets (Ofgem) undertook a series of trials on communication-based interventions to encourage consumer switching in the United Kingdom. The main purpose of this paper is to assess the experience of these Ofgem trials with a view to draw some lessons for policy makers. The analytical framework adopted for this purpose is informed by existing literature on the barriers for consumer switching. The results of the analysis suggest that while the Ofgem trials have made positive impacts on consumer switching, these impacts varied significantly across the trials, suggesting that some interventions were more effective than others. Further, the overall impacts of the Ofgem trials were moderate, as around 70% of participants did not switch suppliers even in the most impactful trial. This reflects a general lack of understanding in the literature about the behaviour-influencing factors, their impacts, and their context-connects. By implication, the difficulty in stimulating consumer switching, as demonstrated by the Ofgem trials, suggests that weak consumer switching and the practice of price discrimination may simply reflect significant competition, rather than a lack of it, especially if retail margins are not greater than the competitive level. In this case, the communication-based intervention aimed at encouraging consumer switching may lead to further price discrimination, especially for the most vulnerable consumers, who are more likely to stay with their incumbent suppliers.

Abstract
We present a comprehensive framework and test methodology for the evaluation of human-machine interfaces (HMI) and human-robot interactions (HRI) in collaborative manufacturing applications. An overview of the challenges that face current- and next-generation collaborative robot systems is presented, specifically focused on the interactions between man and machine, and a series of objectively quantitative and subjectively qualitative metrics are given to guide the development and assessment of interfaces and interactions. A generalized set of guidelines for the design of HMI is also proposed to address these challenges and thereby enable effective and intuitive diagnostics and error corrections when process failures occur. These guidelines are aimed at aiding researchers in developing effective interface and interaction technologies, maximizing operator situation awareness in human-robot collaborative manufacturing teams, promoting effective process and system diagnostics reporting, and enabling faster responses to equipment or application errors.

Abstract
Job passion has recently gained increasing attention, as it is crucial to employee well-being and performance. To simultaneously highlight the current trends with regard to environmental issues and organizational psychology, this article investigates the potential antecedents (i.e. environmental stewardship orientation (ESO) and job autonomy) and consequences (i.e. job satisfaction, life satisfaction, and intention to leave) of harmonious job passion among employees working in green restaurants in Taiwan. Data collected from 299 valid samples were analyzed using structural equation modeling. The results indicate that employees’ ESO and perceived job autonomy positively affect their harmonious job passion. Besides, employees with harmonious job passion may have positive job- and life-related outcomes, including high job and life satisfaction, and low intention to leave. The theoretical and practical implications of the findings are discussed, and directions for future research are identified.

Abstract
BACKGROUND Heart failure (HF) and cancer patients share similarities in symptom burden and depression prevalence. Coping resources, such as optimism have been associated with improved health-related quality of life (HRQoL) and mental health. OBJECTIVES To investigate a wide range of resources in a large population-based sample of HF patients; to compare resources between three groups: HF patients, cancer patients, and individuals having no chronic condition. METHODS This cross-sectional analysis was performed among n = 2761 subjects who participated in home visits during the 11-year follow-up of the epidemiological ESTHER study. Resources were assessed by trained medical doctors through a questionnaire that lists 26 items. One-way analyses of covariance (ANCOVAs) controlled for sociodemographic variables and depression were performed to compare resources between groups. RESULTS Family and self-efficacy were the most frequently reported resources in all groups. HF patients reported optimism significantly less frequently as a resource in comparison to cancer patients (p=.031). HF patients showed significantly lower levels of resource factor 3 (positive attitude), compared to cancer patients (p=.006), and not chronically ill participants (p=.037). CONCLUSIONS Family and self-efficacy seem to be the most important resources, regardless of diagnosis. HF patients appear to have significantly lower levels of resources concerning positive attitude, compared to cancer patients, and not chronically ill individuals. We suggest the development of psychosocial interventions to enhance optimism in HF.

Abstract
BACKGROUND Infodemiology is an emerging field of research that utilizes user-generated health-related content, such as that found in social media, to help improve public health. Twitter has become an important venue for studying emerging patterns in health issues such as substance use because it can reflect trends in real-time and display messages generated directly by users, giving a uniquely personal voice to analyses. Over the past year, several states in the United States have passed legislation to legalize adult recreational use of cannabis and the federal government in Canada has done the same. There are few studies that examine the sentiment and content of tweets about cannabis since the recent legislative changes regarding cannabis have occurred in North America. OBJECTIVE To examine differences in the sentiment and content of cannabis-related tweets by state cannabis laws, and to examine differences in sentiment between the United States and Canada between 2017 and 2019. METHODS In total, 1,200,127 cannabis-related tweets were collected from January 1, 2017, to June 17, 2019, using the Twitter application programming interface. Tweets then were grouped geographically based on cannabis legal status (legal for adult recreational use, legal for medical use, and no legal use) in the locations from which the tweets came. Sentiment scoring for the tweets was done with VADER (Valence Aware Dictionary and sEntiment Reasoner), and differences in sentiment for states with different cannabis laws were tested using Tukey adjusted two-sided pairwise comparisons. Topic analysis to determine the content of tweets was done using latent Dirichlet allocation in Python, using a Java implementation, LdaMallet, with Gensim wrapper. RESULTS Significant differences were seen in tweet sentiment between US states with different cannabis laws (P=.001 for negative sentiment tweets in fully illegal compared to legal for adult recreational use states), as well as between the United States and Canada (P=.003 for positive sentiment and P=.001 for negative sentiment). In both cases, restrictive state policy environments (eg, those where cannabis use is fully illegal, or legal for medical use only) were associated with more negative tweet sentiment than less restrictive policy environments (eg, where cannabis is legal for adult recreational use). Six key topics were found in recent US tweet contents: fun and recreation (keywords, eg, love, life, high); daily life (today, start, live); transactions (buy, sell, money); places of use (room, car, house); medical use and cannabis industry (business, industry, company); and legalization (legalize, police, tax). The keywords representing content of tweets also differed between the United States and Canada. CONCLUSIONS Knowledge about how cannabis is being discussed online, and geographic differences that exist in these conversations may help to inform public health planning and prevention efforts. Public health education about how to use cannabis in ways that promote safety and minimize harms may be especially important in places where cannabis is legal for adult recreational and medical use.

Abstract
The COVID-19 pandemic has presented unique circumstances that have the potential to both positively and negatively affect pediatric adherence and self-management in youth with chronic medical conditions. The following paper discusses how these circumstances (e.g., stay-at-home orders, school closures, changes in pediatric healthcare delivery) impact disease management at the individual, family, community, and healthcare system levels. We also discuss how barriers to pediatric adherence and self-management exacerbated by the pandemic may disproportionately affect underserved and vulnerable populations, potentially resulting in greater health disparities. Given the potential for widespread challenges to pediatric disease management during the pandemic, ongoing monitoring and promotion of adherence and self-management is critical. Technology offers several opportunities for this via telemedicine, electronic monitoring, and mobile apps. Moreover, pediatric psychologists are uniquely equipped to develop and implement adherence-promotion efforts to support youth and their families in achieving and sustaining optimal disease management as the current public health situation continues to evolve. Research efforts addressing the short- and long-term impact of the pandemic on pediatric adherence and self-management are needed to identify both risk and resilience factors affecting disease management and subsequent health outcomes during this unprecedented time.

Abstract
Sequential skill learning with practice is fundamental to human activity (e.g., tying shoes). Given the lack of prior knowledge in most participants, Origami folding is a promising task to study the acquisition of a sequential skill. While previous Origami folding studies mainly dealt with the question, which forms of instruction can lead to better learning outcomes, we employ a dual-task approach to test which resources are necessary for folding and for improvement with practice. Participants (N = 53) folded five Origami figures for four times each, which were randomly paired with five types of secondary tasks to cause either cognitive (verbal vs. visuospatial) or motoric (isochronous vs. non-isochronous tapping) memory load or none (control condition). Origami performance showed a typical learning curve from Trial 1 (first run of folding the figure) to Trial 4 (fourth run of folding the same figure). We tested for a dissociation between variants of memory load influencing Origami folding performance vs. the variants influencing learning (i.e. change in performance across practice). In line with theories suggesting that learning operates on the level that (at a given point in practice) demands the most control, we did not observe cases where a dual-task variant influenced performance while it did not affect learning. Memory load from the cognitive visuospatial secondary task as well as the isochronous tapping secondary task interfered with improvement in Origami folding with practice. This might be due to the use of visuospatial sketchpad and absolute timing mechanism during the acquisition of Origami folding.

Abstract
Diagnostic ion-molecule reactions employed in tandem mass spectrometry experiments can frequently be used to differentiate between isomeric compounds unlike the popular collision-activated dissociation methodology. Selected neutral reagents, such as 2-methoxypropene (MOP), are introduced into an ion trap mass spectrometer where they react with protonated analytes to yield product ions that are diagnostic for the functional groups present in the analytes. However, the understanding and interpretation of the mass spectra obtained can be challenging and time-consuming. Here, we introduce the first bootstrapped decision tree model trained on 36 known ion-molecule reactions with MOP. It uses the graph-based connectivity of analytes' functional groups as input to predict whether the protonated analyte will undergo a diagnostic reaction with MOP. A Cohen kappa statistic of 0.70 was achieved with a blind test set, suggesting substantial inter-model reliability on limited training data. Prospective diagnostic product predictions were experimentally tested for 13 previously unpublished analytes. We introduce chemical reactivity flowcharts to facilitate chemical interpretation of the decisions made by the machine learning method that will be useful to understand and interpret the mass spectra for chemical reactivity.

Abstract
Children’s electronic media use in the form of Internet has increased over the past decades. The activities that children engage using the Internet can lead to experiencing positive as well as negative outcomes. Recent studies have found that excessive time devoted to the Internet use and behavioral narrowing can lead to Internet addiction (Enagandula et al., 2018) or compulsive Internet use (Meerkerk et al., 2009). This phenomenon can be described as a greater risk of developing excessive online habits, which may result in impairments of individual’s activities of daily living as well as relationships with others. Specific characteristics of these associations, however, have been examined only minimally in young children. The goal of this study was to examine the peculiarities of elementary school-aged children’s Internet use in relation to sociodemographic and relationships with others, as well as possible behavioral and emotional difficulties. The sample consisted of 304 parent-child dyads. All children in the study were second or third grade students (mean age 8.47 years, SD = 0.56), 50.3% were boys. Children and parents completed the Compulsive Internet Use Scale (CIUS; Meerkerk et al., 2009) and provided information about time spent on the Internet. Parents provided sociodemographic information and completed the Strengths and Difficulties Questionnaire (SDQ; Goodman, 1997), and children answered questions about their relationships with their parents and peers. The results of the study revealed significant gender differences in compulsivity of the Internet use, i.e. the estimates of boys CIUS – both provided by children and their parents – were significantly higher than girls. In overall, there was good agreement between parental and children’s reports on child’s CIUS, however parents reported higher CIUS scores and longer Internet use than children themselves. Regression analysis revealed that children’s CIUS is predicted (a) from the child’s perspective – by longer Internet time together with lower scores of child prosocial behavior, male gender, less advantaged financial situation in the family, and poorer parent-child relationships; (b) from the parent’s perspective – by longer Internet time, male gender, lower scores of child prosocial behavior, higher scores of behavioral and emotional difficulties together with less advantaged financial family status. The findings of the study are discussed in light of evidence-based practice and research.

Abstract
Recognition-induced forgetting is the category-specific forgetting of pictures that occurs when a subset of a category of pictures is recognized, leading to forgetting of the remaining pictures. We have previously shown that recognition-induced forgetting does not operate over categories created by temporal relationships, suggesting that this effect does not operate over episodic memory representations. Here we systematically tested whether schematically related categories of pictures are immune to recognition-induced forgetting. We found that sufficiently weak schematically related memories are vulnerable to recognition-induced forgetting. These results offer an alternative interpretation for evidence that recognition-induced forgetting does not operate over episodic memory representations. Evidence that the strength of schematic grouping modulates forgetting supports a model of recognition-induced forgetting in which the key determinant of forgetting is moderate activation. This is the first demonstration that recognition-induced forgetting operates over perceptually distinct objects, demonstrating the ubiquity of such forgetting.

Abstract
People rely on their social relationships to help them cope with many stressors over the course of their lives. Across three experiments, we randomly assigned people to experience minor adversity or not and then to experience perceived social support (via belonging affirmation) or not. We found that those who underwent adversity without perceived social support had lower scores on personal resources (e.g., gratitude, connectedness) than the other conditions. In addition, we tested whether perceived social support helps people grow following adversity or simply buffers them from adversity-related declines in personal resources. Our findings comparing growth and buffering hypotheses were mixed; however, the evidence for buffering was slightly stronger than the evidence for growth. Thus, more research is needed to determine whether perceived social support buffers decrements in personal resources following adversity or actually promotes growth. Nevertheless, perceived social support is an important source of resilience when facing life's inevitable challenges.

Abstract
The general benefits of social support are well-documented; however, little is understood about the unique contributions of social support from specific sources, such as parents and peers. In addition, it is unknown whether social support from some sources might buffer against a lack of social support from another source for the outcome of internalizing problems. The current study investigated two research questions: (a) What is the association between social support from mothers, fathers, classmates, and close friends and internalizing problems for adolescent boys and girls? and (b) Can social support from one source (e.g., mothers) buffer against internalizing problems when social support from another source (e.g., fathers) may be lacking? Do these associations vary by gender? These research questions were examined with a sample of 364 middle school students (61.3% female). Students completed a series of self-report questionnaires assessing social support and internalizing symptoms. Multiple group structural equation models indicated that social support provided general benefits from all sources for early adolescent boys and girls. Regarding stress-buffering with low support as a stressor, no evidence was found for compensation between mothers and fathers. Mother support compensated for low classmate support for both boys and girls and father support compensated for low classmate support for boys. Classmate support compensated for low close friend support for boys. Implications in the context of the school environment for both boys and girls are discussed.

Abstract
The impact of corporate social responsibility (CSR) activities on companies’ macroeconomic indicators (financial performance, sustainability) has been the subject of many studies. However, more recently, the effect of CSR activities on individual variables (microeconomic indicators) has begun to attract attention. Although CSR itself is founded on the moral roots of the society in which it operates, it seems that the effect of individuals’ moral attentiveness has been neglected. The CSR effect, which is the focus of this study, is examined using three dimensions to understand how CSR can directly and indirectly affect the organizational commitment of employees. A theoretical model is developed in this paper, the focus of which is on the ethical framework of CSR and the proposition that it may have an effect on employees. The sample comprises individuals working in two of the country’s most important private production facilities in the western capital of Turkey. An online questionnaire form was prepared and shared. The online form was active between 2 March 2020 and 11 May 2020. Out of 472 forms, 465 were usable and, therefore, used in the analyses. We found proof for most of our assertions. Implications and future research suggestions are discussed.

Abstract
A Ganzfeld is a homogenized visual and auditory perceptual field which can induce altered states of consciousness (ASC; Metzger, 1929; Schmidt & Prein, 2019). Using a balanced intrasubject design, we compared participants' experience during two differently colored (red, green) 25-min Ganzfeld sessions with brown noise as acoustic stimulation. Participants were exposed to the colored visual field through commercially available goggles and to brown noise over headphones. We selected 67 participants with some prior meditation experience to increase the probability that they would engage meaningfully with this specifically restricted stimulus situation. We tested the functional components of the standard cognitive model of time perception (Zakay & Block, 1997) in a path analysis for direct (red vs. green light) and indirect effects (arousal, attention) on subjective duration and perceived passage of time. Subjective arousal and valence states were measured using the Self-Assessment Manikin (SAM). The amount of attention directed to time and the perceived passage of time were rated with standard visual analog scales (VAS). Participants also estimated the duration of each Ganzfeld exposure. The session with the red visual field lasted significantly longer than did the green session (μred = 23.1 min; μgreen = 19.8 min). After the green session, participants rated their arousal level to have significantly decreased; after the red session, individuals on average felt emotionally less positive. Multiple path analyses revealed that the effect of color on estimated duration is completely mediated through higher arousal levels during the red Ganzfeld session. In turn, the higher arousal level generates a longer subjective estimate of duration. For induction of relaxation in studies probing altered states of consciousness employing the Ganzfeld technique, we recommend using the green light.

Abstract
Background Spanking can cause adverse psychological development and biological functional changes in children. However, spanking is widely used by parents in Japan. This study explored the risk factors for family member’s spanking of 3.5-year-old children using nationwide population data in Japan. Methods Surveys were administered to family members in Japan who had a child in 2001 (first cohort) or in 2010 (second cohort), and the data when their child was 0.5, 1.5, and 3.5 years old were used. We used multivariate binary and ordinal logistic regression analyses to examine the associations between risk factors and spanking children at 3.5 years of age, which was subcategorized into frequencies of never, sometimes, and always spanking, presented with odds ratios (ORs) and 95% confidence intervals (CIs). Results Among 70,450 families, 62.8% and 7.9% sometimes and always spanked their children, respectively. Children in the second cohort were spanked less frequently compared with those in the first cohort, and fathers who responded to the questionnaire spanked children less frequently than mothers who responded. Identified associated factors for spanking were male child, presence of siblings of the child, not living in a two-parent household, not living in a three-generation household, younger parents, parents with lower education, no outside work or unstable work, and lower family income. Conclusions We found a high prevalence of spanking and its associated factors. Approaching those with lower socioeconomic factors and promoting fathers’ involvement in parenting may be important public health strategies for reducing and preventing spanking.

Abstract
This study investigates the association between children's peer-reported expression of anger and their pretend play with aggressive/negative themes observed during spontaneous play with classmates. Participants comprised 104 Chinese children (Mage = 8.98 years, SD = 0.97, 49% girls) and were filmed playing in peer dyads with toys. Aggressive and non-aggressive negative pretend themes were coded at five-second intervals for 10 minutes. Children's expression of anger in real situations was reported by peers. Analysis using actor-partner interdependence modelling (APIM) revealed significant partner effects, indicating that children were more likely to engage in pretend play with aggressive themes when they were playing with a partner who was perceived by their peers as more easily angered. It was also found that boys were more likely to engage in pretend play with both aggressive and non-aggressive negative themes compared with girls.
