Neural and Attentional Correlates of Intrinsic Motivation Resulting from Social Performance Expectancy

Some models of motivation distinguish between intrinsic and extrinsic motivation. While past work has examined the neural and cognitive correlates of extrinsic motivation, research on intrinsic motivation has relied primarily on behavioral measures of performance and learning. In particular, no past work has examined the neural and cognitive correlates of social performance expectancy, which is linked to intrinsic motivation. The current study manipulated expectancy of difficult (vs. easy) trials on a cued flanker task and assessed attentional scope and performance. EEG was used to examine motor-action preparation as measured by suppression of beta band activity over the motor cortex and feedback processing as measured by the Reward Positivity (RewP). Results revealed expectancy of difficult (vs. easy) trials narrowed attentional scope, reduced beta activity over the motor cortex, and enhanced RewP amplitudes to win feedback. These findings suggest that enhancing intrinsic motivation through expectancies of positive social comparison engages similar neural and cognitive correlates as extrinsic motivators high in motivational intensity.

When do job insecure employees adapt to change?

Purpose

The purpose of this paper is to examine the relationship between job insecurity and adaptive performance (AP), contingent on changes to core work tasks, which we position as a situational cue to employees regarding important work behaviors.

Design/methodology/approach

Employees and their supervisors were invited to participate in the study. Supervisors were asked to provide ratings of employees’ AP and changes to core tasks; employees reported on job insecurity.

Findings

As predicted, changes to core tasks moderated the relationship between job insecurity and AP. Job insecurity was negatively related to AP for those experiencing low levels of change, but was not related to AP for those experiencing high levels of change. Counter to expectations, no main effect of job insecurity was found.

Research limitations/implications

This study employed a fairly small sample of workers from two organizations, which could limit generalizability.

Practical implications

The study identifies changes to core tasks as a boundary condition for the job insecurity–AP relationship. Findings suggest that organizations may not observe deleterious consequences of job insecurity on AP when changes to core tasks are high.

Originality/value

Few researchers have examined boundary conditions of the impact of job insecurity on AP. Furthermore, inconsistent findings regarding the link between job insecurity and AP have emerged. This study fills the gap and expands upon previous research by examining changes to core tasks as a condition under which job insecurity does not pose an issue for AP.

Affect and Decision Making: Insights and Predictions from Computational Models

In recent years interest in integrating the affective and decision sciences has skyrocketed. Immense progress has been made, but the complexities of each field, which can multiply when combined, present a significant obstacle. A carefully defined framework for integration is needed. The shift towards computational modeling in decision science provides a powerful basis and a path forward, but one whose synergistic potential will only be fully realized by drawing on the theoretical richness of the affective sciences. Reviewing research using a popular computational model of choice (the drift diffusion model), we discuss how mapping concepts to parameters reduces conceptual ambiguity and reveals novel hypotheses.

The Childhood Maltreatment Modulates the Impact of Negative Emotional Stimuli on Conflict Resolution

It has been reported that negative emotional stimuli could facilitate conflict resolution. However, it remains unclear about whether and how the impact of negative emotional stimuli on conflict resolution varies depending on childhood maltreatment. To clarify this issue, seventy-nine subjects were required to perform an arrow Eriksen Flanker Task which was presented in the center of emotional pictures. The present study found a significant interaction effect of childhood maltreatment and emotion on executive attention scores in reaction times (RTs) that reflect conflict resolution speed. For subjects in high childhood maltreatment, negative pictures elicited smaller executive attention scores in RTs than neutral and positive pictures, while neutral and positive pictures elicited similar executive attention scores in RTs. By contrast, for subjects in low childhood maltreatment, executive attention scores in RTs were similar across three conditions. These results suggest that the speed of conflict resolution is enhanced in high, instead of low, childhood maltreatment in situations of negative stimuli. This finding extends our understanding of the interaction among emotion, childhood maltreatment and conflict resolution.

Splitting the affective atom: Divergence of valence and approach-avoidance motivation during a dynamic emotional experience

Valence and approach-avoidance motivation are two distinct but closely related components of affect. However, little is known about how these two processes evolve and covary in a dynamic affective context. We formulated several hypotheses based on the Motivational Dimensional Model of Affect. We expected that anger would be a unique approach-related rather than avoidance-related negative emotion. We also expected that high-approach positive emotions (e.g., desire) would differ from low-approach positive emotions (e.g., amusement) producing a stronger link between valence and approach-avoidance motivation. We also explored other dynamic properties of discrete emotions such as the difference between approach-avoidance motivation and valence as a marker of balance within affective components. We asked 69 participants to provide continuous ratings of valence and approach-avoidance motivation for eight standardized clips representing different discrete emotions. Using multilevel modeling, we established a significant relationship between valence and approach-avoidance motivation with high-approach emotions producing a stronger link between valence and approach-avoidance motivation compared to neutral states and low-approach emotions. Contrary to expectations, we observed that individuals exhibited an avoidance response during anger elicitation. Finally, we found that awe was a distinct positive emotion where approach motivation dominated over valence. These findings are relevant to the theory and research on diverging processes within the core structure of affect.

Workplace ostracism and discretionary work effort: A conditional process analysis

Drawing on affective events theory (AET) and workplace incivility spiral, this study tested a conditional process model to explain, when and how, affective workplace events (workplace ostracism and workplace incivility) affect employees’ emotions and work effort. Data for this cross-sectional study were collected via an online survey from 251 employees at three public sector universities in Quetta, Pakistan. Results indicated that both ostracism and incivility encumber work effort, and that one way via which ostracism negatively affects work effort is by provoking targets’ negative affect (NA). Results also revealed that workplace incivility exacerbated positive relationship of ostracism and NA such that this relationship was stronger when incivility was high and weaker when incivility was low. Moreover, the indirect effects of ostracism on work effort were also contingent on workplace incivility. Practical implications are discussed at the end.

Lost in the forest? Global to local interference depends on children's reading skills

We studied the global precedence effect in primary school children with and without developmental dyslexia, using a compound figures task with familiar (Latin) or unfamiliar (Hebrew) letters. The two components of the global precedence effect were considered separately: global advantage (faster processing of global than local letters) and asymmetric interference (global distracters interfere with local targets but not vice versa). Both groups of children showed a global advantage with familiar as well as with unfamiliar letters. Children without developmental dyslexia showed asymmetric interference on familiar letters, but not on unfamiliar ones. Children with developmental dyslexia showed no asymmetric interference, neither for familiar letters nor for unfamiliar ones. The results distinguish between alternative hypothesis regarding the roles of familiarity and visual processing strategies in the compound figures task. Consequences for understanding literacy acquisition and developmental dyslexia are discussed.

Conflict Adaptation in 5-Year-Old Preschool Children: Evidence From Emotional Contexts

This research investigated the individual behavioral and electrophysiological differences during emotional conflict adaptation processes in preschool children. Thirty children (16 girls, mean age 5.44 ± 0.28 years) completed an emotional Flanker task (stimulus-stimulus cognitive control, S-S) and an emotional Simon task (stimulus-response cognitive control, S-R). Behaviorally, the 5-year-old preschool children exhibited reliable congruency sequence effects (CSEs) in the emotional contexts, with faster response times (RTs) and lower error rates in the incongruent trials preceded by an incongruent trial (iI trial) than in the incongruent trials preceded by a congruent trial (cI trial). Regarding electrophysiology, the children demonstrated longer N2 and P3 latencies in the incongruent trials than in the congruent trials during emotional conflict control processes. Importantly, the boys showed a reliable CSE of N2 amplitude when faced with fearful target expression. Moreover, 5-year-old children showed better emotional CSEs in response to happy targets than to fearful targets as demonstrated by the magnitude of CSEs in terms of the RT, error rate, N2 amplitude and P3 latency. In addition, the results demonstrated that 5-year-old children processed S-S emotional conflicts and S-R emotional conflicts differently and performed better on S-S emotional conflicts than on S-R emotional conflicts according to the comparison of the RT-CSE and P3 latency-CSE values. The current study provides insight into how emotionally salient stimuli affect cognitive processes among preschool children.

Does Cognitive Broadening Reduce Anger?

Past theory and research have suggested that motivationally intense affective states narrow cognitive scope. Research has also suggested manipulations that broaden cognitive scope reduce responses to appetitive positive affective stimuli and disgusting stimuli, thus suggesting that cognitive broadening reduces motivational intensity. This led to the hypothesis that cognitive broadening would reduce the approach-motivated negative emotion of anger. Seven studies assessed the effect of cognitive broadening on reported trait anger, state anger, attitudes toward anger, attributions of anger to ambiguous pictures, and accessibility of aggressive words. Results from individual studies found mixed support for these predictions. A meta-analysis, however, suggested a small but significant effect on trait anger/aggression and attitudes toward anger across studies. These results may indicate that cognitive scope, as manipulated in these studies, has a small effect on anger-related responses. Discussion speculates on potential explanations of these findings, and their importance for informing future research.

Attentional bias assessed by a facial expression cuing paradigm in infants

To disambiguate infants’ attentional bias towards fearful facial expressions, we applied a facial expression cueing paradigm to 36 6-month-old and 33 12-month-old infants, with 21 infants taking part at both ages. Infants made saccades towards a peripheral target preceded by a happy, fearful, or neutral cue directing their attention to the target location (congruent) or the wrong location (incongruent). The results show that infants were faster to respond when shown a fearful (vs. happy) face as a congruent cue, which is consistent with previous studies referring to fearful vigilance, while an incongruent fearful cue reduces attention shifts to the target on the opposite side of the monitor to a greater extent than an incongruent happy cue at 12 months, implying that a fearful facial expression prolongs attentional disengagement or is associated with a greater narrowing of attention. Additionally, the latencies of 6-month-olds were significantly faster than those of 12-month-olds in a congruent condition. The relationship between attentional bias and temperamental disposition was examined using the Infant Behavior Questionnaire–Revised. High temperamental orienting scores partly correlated with attentional bias at 12 months. The contributions of attentional brain networks to socio-cognitive and emotional development are also discussed.

The Motivational Power of the Happy Face

People who are cheerful have better social relationships. This might be the case because happy faces communicate an invitation to interact. Thus, happy faces might have a strong motivational effect on others. We tested this hypothesis in a set of four studies. Study 1 (N = 94) showed that approach reactions to happy faces are faster than other reactions to happy or angry faces. Study 2 (N = 99) found the same effect when comparing reactions to happy faces with reactions to disgusted faces. Supporting the notion that this effect is related to motivation, habitual social approach motivation intensified the motivational effect of happy faces (Study 3, N = 82). Finally, Study 4 (N = 40) showed that the reaction-time asymmetry does not hold for categorization tasks without approach and avoidance movements. These studies demonstrate that happy faces have a strong motivational power. They seem to activate approach reactions more strongly than angry or disgusted faces activate avoidance reactions.

Aripiprazole/Methylphenidate Combination in Children and Adolescents with Disruptive Mood Dysregulation Disorder and Attention-Deficit/Hyperactivity Disorder: An Open-Label Study

OBJECTIVES

Disruptive mood dysregulation disorder (DMDD) is characterized by nonepisodic irritability and has a high rate of comorbidity with attention-deficit/hyperactivity disorder (ADHD). This is the first study to explore the effects of aripiprazole combined with methylphenidate on clinical symptoms and cognitive functions in patients with DMDD and ADHD.

METHODS

Patients with DMDD and ADHD (the DMDD-ADHD Group, n = 24; aged 7-17 years) completed a 6-week, open-label trial of aripiprazole and methylphenidate. The pre- and posttreatment outcome measures included the parent-rated Swanson, Nolan, and Pelham Scale-version IV, Child Behavior Checklist, and self-reported Beck Youth Inventories-II, as well as a neuropsychological battery composed of the Children's Color Trail Test and Conner's Continuous Performance Test. The comparison group consisting of patients with ADHD (the ADHD Group, n = 27) was recruited to investigate the differences in clinical and neuropsychological profiles between the two groups at baseline.

RESULTS

The DMDD-ADHD Group showed worse irritability, disruptive behaviors, anxious/depressed symptoms, and social problems relative to the ADHD Group at baseline assessments. The combination treatment significantly improved irritability, externalizing symptoms, depression, anxiety, attention, social problems, and reaction time variability. The effect sizes of reductions in parent-rated irritability, oppositional defiant symptoms, and inattention were comparable (Cohen's d = 1.26, 1.11, and 1.40, respectively).

CONCLUSIONS

This pilot study showed the tolerability of the aripiprazole/methylphenidate combination by patients with DMDD and ADHD and its efficaciousness for treating clinical symptoms and for improving cognitive function. Further randomized, controlled, cross-over studies are needed.

Effect of emotional cues on prospective memory performance in patients with schizophrenia and major depressive disorder

Prospective memory (PM) is the ability to remember to carry out future intentions when prompted by a cue, and previous studies have suggested that emotional PM cues may enhance PM performance. This study examined the influence of emotional cues on PM performance in patients with schizophrenia and major depressive disorder. All participants were required to respond to emotional or neutral PM cues while completing a working memory task. Healthy participants showed improved PM performance with positive and negative cues. Patients with major depressive disorder were not impaired in PM performance and showed significant improvement in PM performance when cued by negative but not positive cues. Patients with schizophrenia had impaired PM performance irrespective of cue emotionality. In addition, the majority of patients with schizophrenia failed to show an emotional enhancement effect, and only those who had normal arousal ratings for negative PM cues showed emotional enhancement effect. These findings show for the first time that patients with schizophrenia exhibit PM impairments even with emotional cues, and suggest that arousal may be a critical factor for schizophrenia patients to utilize emotional cues to facilitate execution of future actions. In patients with major depressive disorder, our findings suggest that the negative bias in attention and retrospective memory may also extend to memory for future actions. These novel findings have both theoretical and clinical implications.

The Personality of the Influencers, the Characteristics of Qualitative Discussions and Their Analysis for Recommendations to Cultural Institutions

Social media usage is affecting peoples’ views through opinion sharing, a fact that has started to attract cultural institutions, as it is possible that this procedure can possibly be a part of a museum experience. As the main goal of a cultural institution is the maximization of senses stimulation, the device that is offered to the visitors’ hands everyday and every moment, becomes an important tool for the art spaces. In this notion we perform research on issues that can be of great importance for the museum’s online presence and attraction. We focus on establishing the personality of influencers related to culture, as well as the characteristics of qualitative discussions on the social media. Crosscult Project is an EU funded project, that aims to spur a change in the way European citizens appraise History, and sets that basis of our research as the experiments are conducted within its scope of. Through the experimental procedure, we collect information in order to define the character of the influencer and the substances of a “serious” conversation. “Serious” conversations are regarded the ones in which a cultural organization can participate actively and benefit from the participation. We present the results of our experimental evaluation and analyze how cultural institutions can benefit from the outcomes of our research.

Affect-Driven Attention Biases as Animal Welfare Indicators: Review and Methods

Attention bias describes the differential allocation of attention towards one stimulus compared to others. In humans, this bias can be mediated by the observer's affective state and is implicated in the onset and maintenance of affective disorders such as anxiety. Affect-driven attention biases (ADABs) have also been identified in a few other species. Here, we review the literature on ADABs in animals and discuss their utility as welfare indicators. Despite a limited research effort, several studies have found that negative affective states modulate attention to negative (i.e., threatening) cues. ADABs influenced by positive-valence states have also been documented in animals. We discuss methods for measuring ADAB and conclude that looking time, dot-probe, and emotional spatial cueing paradigms are particularly promising. Research is needed to test them with a wider range of species, investigate attentional scope as an indicator of affect, and explore the possible causative role of attention biases in determining animal wellbeing. Finally, we argue that ADABs might not be best-utilized as indicators of general valence, but instead to reveal specific emotions, motivations, aversions, and preferences. Paying attention to the human literature could facilitate these advances.

The Value of Being Discrete: The Differential and Causal Effects of Positive Affect and Discrete Positive Emotions on Organ Donor Registration Outcomes

BACKGROUND

The current studies examined how positive affect (i.e. the blend of several positive feelings over time) and discrete positive emotions (i.e. a specific set of momentary thoughts and feelings) influence organ donor registration outcomes.

METHODS

In Study 1, participants were randomly assigned to a writing task intended to elicit positive or negative affect. In Study 2, participants received a discrete positively valenced emotion induction (i.e. elevation, humor, hubristic pride), or were in a control condition.

RESULTS

Study 1 (N = 503) indicated a causal relationship between general positive affect and registration attitudes. An indirect effect beginning with general positive affect, going through attitudes, and then intentions, to influence behavior was also indicated. Study 2a (N = 394) demonstrated that elevation, humor, and hubristic pride can be influenced using an online platform. Study 2b (N = 1,046) indicated a causal relationship between elevation and increased registration intentions and behavior. The humor recall task caused marginally significant greater registration intentions, but no significant behavioral differences. The hubristic pride task did not influence registration outcomes.

CONCLUSION

Organ donor practitioners and scholars could benefit from increased focus on the emotional states likely to be experienced at different venues when considering intervention contexts.

What Makes Us Feel Good or Bad

Abstract. Affective science calls for methods to induce mood in an engaging and ecologically valid way. We present a method employing a naturally occurring scenario that fits these criteria: a job interview. Participants got positive or negative feedback from a fictive expert to induce positive or negative mood. After mood induction, we assessed participants’ decision making behavior in the so-called information sampling task (IST). Results show that our mood induction successfully changed valence, dominance, and state self-esteem ratings, while there were no differences in arousal ratings. Decision making in the IST was not influenced by the induced mood. Effect sizes of mood induction were equally high for positive and negative mood concerning valence ratings (d = .8) with participants scoring high on self-control showing smaller mood induction effects. We conclude that our mood induction technique is an effective and natural way to induce mood in the laboratory, meeting current criteria of affective science.

A Judgement Bias Test to Assess Affective State and Potential Therapeutics in a Rat Model of Chemotherapy-Induced Mucositis

Chemotherapy-induced mucositis is an extremely painful condition that occurs in 40-60% of patients undergoing chemotherapy. As mucositis currently has no effective treatment, and due to the self-limiting nature of the condition, the major treatment aims are to manage symptoms and limit pain with significance placed on improving patient quality of life. Rodent models are frequently used in mucositis research. These investigations typically assess pathological outcomes, yet fail to include a measure of affective state; the key therapeutic goal. Assessment of cognitive biases is a novel approach to determining the affective state of animals. Consequently, this study aimed to validate a cognitive bias test through a judgement bias paradigm to measure affective state in a rat model of chemotherapy-induced intestinal mucositis. Rats with intestinal mucositis demonstrated a negative affective state, which was partially ameliorated by analgesic administration, whilst healthy rats showed an optimistic response. This study concluded that the judgement bias test was able to evaluate the emotional state of rats with chemotherapy-induced mucositis. These findings provide a foundation for future refinement to the experimental design associated with the animal model that will expedite successful transitioning of novel therapeutics to clinical practice, and also improve humane endpoint implementation.

Directionality of the relationship between social well-being and subjective well-being: evidence from a 20-year longitudinal study

PURPOSE

Self-determination theory suggests that psycho-social well-being prospectively predicts subjective well-being. In contrast, the broaden-and-build theory of positive emotions suggests that subjective well-being has a positive impact on subsequent levels of psycho-social well-being. The present study sought to empirically disentangle the directionality of the relationship between subjective well-being and social well-being over time.

METHODS

The study used three waves of survey data, with intervals of 10 years, from the Midlife in the United States (MIDUS) project, a representative longitudinal panel study of American adults (N = 2732). Cross-lagged panel modeling was used for data analysis.

RESULTS

The results revealed that social well-being predicted increases in subsequent subjective well-being, whereas subjective well-being did not prospectively predict social well-being. Social well-being also demonstrated more stability over time than did subjective well-being.

CONCLUSION

These findings suggest that optimal social functioning is more likely to be an antecedent to subjective well-being, not the other way around. The results are consistent with predictions guided by self-determination theory.

Seeing the big picture: Broadening attention relieves sadness and depressed mood

We examined whether the broadened attentional scope would affect people's sad or depressed mood with two experiments, enlightened by the meaning of "seeing the big picture" and the broaden-and-build model. Experiment 1 (n = 164) is a laboratory-based experiment, in which we manipulated the attentional scope by showing participants zoomed-out or zoomed-in scenes. In Experiment 2 (n = 44), we studied how depressed mood and positive and negative emotions were affected when participants watched distant versus proximal scenes for eight weeks in real life. Healthy participants in Experiment 1, who were induced to feel sad, could return to the baseline mood after having the broadened attention task but not after having the narrowed attention task, which indicated that immediate attention broadening manipulation could function as antidotes for the lingering effects of induced negative emotions. Participants with depressed mood in Experiment 2 showed reduced depressed mood, increased positive affect, and decreased negative affect after receiving attention broadening training compared to those receiving attention narrowing training. Our findings suggest a robust role of broadened attentional scope in relieving negative emotions and even mildly depressed mood in the long run.

Negative affect varying in motivational intensity influences scope of memory

Emotions influence cognitive processes involved in memory. While some research has suggested that cognitive scope is determined by affective valence, recent models of emotion-cognition interactions suggest that motivational intensity, rather than valence, influences these processes. The present research was designed to clarify how negative affects differing in motivational intensity impact memory for centrally or peripherally presented information. Experiments 1 & 2 found that, relative to a neutral condition, high intensity negative affect (anger) enhances memory for centrally presented information. Experiment 3 replicated this effect using another high intensity negative affect (threat). Experiment 4 extended this by finding that, relative to a neutral condition, low intensity negative affect (sadness) enhanced memory for peripherally presented information. Finally, in Experiment 5, the effects of sadness and threat on scope of memory were directly compared, finding that threat narrowed scope of memory, while sadness broadened scope of memory. Together, these results provide additional support for the motivational dimensional model of cognitive scope, in that high intensity emotions narrow cognitive scope, while low intensity emotions broaden cognitive scope.

Exploring the emotional dynamics of subclinically depressed individuals with and without anhedonia: An experience sampling study

BACKGROUND

Anhedonia has been linked to worse prognosis of depression. The present study aimed to construct personalized models to elucidate the emotional dynamics of subclinically depressed individuals with versus without symptoms of anhedonia.

METHODS

Matched subclinically depressed individuals with and without symptoms of anhedonia (N = 40) of the HowNutsAreTheDutch sample completed three experience sampling methodology assessments per day for 30 days. For each individual, the impact of physical activity, stress experience, and high/low arousal PA/NA on each other was estimated through automated impulse response function analysis (IRF). These individual IRF associations were combined to compare anhedonic versus non-anhedonic individuals.

RESULTS

Physical activity had low impact on affect in both groups. In non-anhedonic individuals, stress experience increased NA and decreased PA and physical activity more strongly. In anhedonic individuals, PA high arousal showed a diminished favorable impact on affect (increasing NA/stress experience, decreasing PA/physical activity). Finally, large heterogeneity in the personalized models of emotional dynamics were found.

LIMITATIONS

Stress experience was measured indirectly by assessing level of distress; the timeframe in between measurements was relatively long with 6h; and only information on one of the two hallmarks of anhedonia, loss of interest, was gathered.

CONCLUSIONS

Our results suggest different pathways of emotional dynamics underlie depressive symptomatology. Subclinically depressed individuals with anhedonic complaints are more strongly characterized by diminished favorable impact of PA high arousal and heightened NA reactivity, whereas subclinically depressed individuals without these anhedonic complaints seem more characterized by heightened stress reactivity. The automatically generated personalized models may offer patient-specific insights in emotional dynamics, which may show clinical relevance.

Neural Correlates of Response Inhibition and Conflict Control on Facial Expressions

Response inhibition and conflict control on affective information can be regarded as two important emotion regulation and cognitive control processes. The emotional Go/Nogo flanker paradigm was adopted and participant’s event-related potentials (ERPs) were analyzed to investigate how response inhibition and conflict control interplayed. The behavioral findings revealed that participants showed higher accuracy to identify happy faces in congruent condition relative to that in incongruent condition. The electrophysiological results manifested that response inhibition and conflict control interplayed during the detection/conflict monitoring stage, and Nogo-N2 was more negative in the incongruent trials than the congruent trials. With regard to the inhibitory control/conflict resolution stage, Nogo responses induced greater frontal P3 and parietal P3 responses than Go responses did. The difference waveforms of N2 and parietal P3 showed that response inhibition and conflict control had distinct processes, and the multiple responses requiring both conflict control and response inhibition processes induced stronger monitoring and resolution processes than conflict control. The current study manifested that response inhibition and conflict control on emotional information required separable neural mechanisms during emotion regulation processes.

Induced Positive Mood and Cognitive Flexibility: Evidence from Task Switching and Reversal Learning

Positive mood often facilitates cognitive functions. Facilitation is hypothesized to be due to an increase in dopamine occurring in positive mood states. However, facilitation has not been consistently found in studies of cognitive flexibility. This inconsistent relationship may reflect the numerous ways cognitive flexibility is measured. Moreover, there is evidence that the role of dopamine in cognitive flexibility performance depends on the type of measure used. In the current study, we employed a probabilistic two-card reversal learning task (n = 129) and a Stroop-like task switching procedure (n = 188) in a college student population. We used a standardized set of mood videos to induce a positive, negative, or neutral mood state. Negative mood states were included to account for possible effects of arousal on performance, which is seen in both positive and negative mood inductions. Based on current theories of positive mood and cognition, we hypothesized that there would be differences in the effects of a positive mood induction on cognitive flexibility as assessed by task switching and reversal learning tasks. The mood induction successfully induced high levels of amusement and increased valence in the positive mood group and high levels of repulsion and decreased valence in the negative mood group. However, there were no differences in cognitive flexibility across any of the mood groups, as assessed by switch costs in task switching and correct choices after the reversal in reversal learning. Overall, these findings do not support the hypothesis that positive mood improves cognitive flexibility.

Lost in Time and Space: States of High Arousal Disrupt Implicit Acquisition of Spatial and Sequential Context Information

Biased cognition during high arousal states is a relevant phenomenon in a variety of topics: from the development of post-traumatic stress disorders or stress-triggered addictive behaviors to forensic considerations regarding crimes of passion. Recent evidence indicates that arousal modulates the engagement of a hippocampus-based "cognitive" system in favor of a striatum-based "habit" system in learning and memory, promoting a switch from flexible, contextualized to more rigid, reflexive responses. Existing findings appear inconsistent, therefore it is unclear whether and which type of context processing is disrupted by enhanced arousal. In this behavioral study, we investigated such arousal-triggered cognitive-state shifts in human subjects. We validated an arousal induction procedure (three experimental conditions: violent scene, erotic scene, neutral control scene) using pupillometry (Preliminary Experiment, n = 13) and randomly administered this method to healthy young adults to examine whether high arousal states affect performance in two core domains of contextual processing, the acquisition of spatial (spatial discrimination paradigm; Experiment 1, n = 66) and sequence information (learned irrelevance paradigm; Experiment 2, n = 84). In both paradigms, spatial location and sequences were encoded incidentally and both displacements when retrieving spatial position as well as the predictability of the target by a cue in sequence learning changed stepwise. Results showed that both implicit spatial and sequence learning were disrupted during high arousal states, regardless of valence. Compared to the control group, participants in the arousal conditions showed impaired discrimination of spatial positions and abolished learning of associative sequences. Furthermore, Bayesian analyses revealed evidence against the null models. In line with recent models of stress effects on cognition, both experiments provide evidence for decreased engagement of flexible, cognitive systems supporting encoding of context information in active cognition during acute arousal, promoting reduced sensitivity for contextual details. We argue that arousal fosters cognitive adaptation towards less demanding, more present-oriented information processing, which prioritizes a current behavioral response set at the cost of contextual cues. This transient state of behavioral perseverance might reduce reliance on context information in unpredictable environments and thus represent an adaptive response in certain situations.

Motivated Cognition: Effects of Reward, Emotion, and Other Motivational Factors Across a Variety of Cognitive Domains

A growing body of literature has demonstrated that motivation influences cognitive processing. The breadth of these effects is extensive and span influences of reward, emotion, and other motivational processes across all cognitive domains. As examples, this scope includes studies of emotional memory, value-based attentional capture, emotion effects on semantic processing, reward-related biases in decision making, and the role of approach/avoidance motivation on cognitive scope. Additionally, other less common forms of motivation–cognition interactions, such as self-referential and motoric processing can also be considered instances of motivated cognition. Here I outline some of the evidence indicating the generality and pervasiveness of these motivation influences on cognition, and introduce the associated ‘research nexus’ at Collabra: Psychology.

Neural signatures of dynamic emotion constructs in the human brain

How is emotion represented in the brain: is it categorical or along dimensions? In the present study, we applied multivariate pattern analysis (MVPA) to magnetoencephalography (MEG) to study the brain's temporally unfolding representations of different emotion constructs. First, participants rated 525 images on the dimensions of valence and arousal and by intensity of discrete emotion categories (happiness, sadness, fear, disgust, and sadness). Thirteen new participants then viewed subsets of these images within an MEG scanner. We used Representational Similarity Analysis (RSA) to compare behavioral ratings to the unfolding neural representation of the stimuli in the brain. Ratings of valence and arousal explained significant proportions of the MEG data, even after corrections for low-level image properties. Additionally, behavioral ratings of the discrete emotions fear, disgust, and happiness significantly predicted early neural representations, whereas rating models of anger and sadness did not. Different emotion constructs also showed unique temporal signatures. Fear and disgust - both highly arousing and negative - were rapidly discriminated by the brain, but disgust was represented for an extended period of time relative to fear. Overall, our findings suggest that 1) dimensions of valence and arousal are quickly represented by the brain, as are some discrete emotions, and 2) different emotion constructs exhibit unique temporal dynamics. We discuss implications of these findings for theoretical understanding of emotion and for the interplay of discrete and dimensional aspects of emotional experience.

On the Importance of Both Dimensional and Discrete Models of Emotion

We review research on the structure and functions of emotions that has benefitted from a serious consideration of both discrete and dimensional perspectives on emotion. To illustrate this point, we review research that demonstrates: (1) how affective valence within discrete emotions differs as a function of individuals and situations, and how these differences relate to various functions; (2) that anger (and other emotional states) should be considered as a discrete emotion but there are dimensions around and within anger; (3) that similarities exist between approach-related positive and negative discrete emotions and they have unique motivational functions; (4) that discrete emotions and broad dimensions of emotions both have unique functions; and (5) evidence that a "new" discrete emotion with discrete functions exists within a broader emotion family. We hope that this consideration of both discrete and dimensional perspectives on emotion will assist in understanding the functions of emotions.

The sound and the fury: Late positive potential is sensitive to sound affect

Emotion is an emergent construct of multiple distinct neural processes. EEG is uniquely sensitive to real-time neural computations, and thus is a promising tool to study the construction of emotion. This series of studies aimed to probe the mechanistic contribution of the late positive potential (LPP) to multimodal emotion perception. Experiment 1 revealed that LPP amplitudes for visual images, sounds, and visual images paired with sounds were larger for negatively rated stimuli than for neutrally rated stimuli. Experiment 2 manipulated this audiovisual enhancement by altering the valence pairings with congruent (e.g., positive audio + positive visual) or conflicting emotional pairs (e.g., positive audio + negative visual). Negative visual stimuli evoked larger early LPP amplitudes than positive visual stimuli, regardless of sound pairing. However, time frequency analyses revealed significant midfrontal theta-band power differences for conflicting over congruent stimuli pairs, suggesting very early (∼500 ms) realization of thematic fidelity violations. Interestingly, late LPP modulations were reflective of the opposite pattern of congruency, whereby congruent over conflicting pairs had larger LPP amplitudes. Together, these findings suggest that enhanced parietal activity for affective valence is modality independent and sensitive to complex affective processes. Furthermore, these findings suggest that altered neural activities for affective visual stimuli are enhanced by concurrent affective sounds, paving the way toward an understanding of the construction of multimodal affective experience.

Sweet-cheeks vs. pea-brain: embodiment, valence, and task all influence the emotional salience of language

Previous research has found that more embodied insults (e.g. numbskull) are identified faster and more accurately than less embodied insults (e.g. idiot). The linguistic processing of embodied compliments has not been well explored. In the present study, participants completed two tasks where they identified insults and compliments, respectively. Half of the stimuli were more embodied than the other half. We examined the late positive potential (LPP) component of event-related potentials in early (400-500 ms), middle (500-600 ms), and late (600-700 ms) time windows. Increased embodiment resulted in improved response accuracy to compliments in both tasks, whereas it only improved accuracy for insults in the compliment detection task. More embodied stimuli elicited a larger LPP than less embodied stimuli in the early time window. Insults generated a larger LPP in the late time window in the insult task; compliments generated a larger LPP in the early window in the compliment task. These results indicate that electrophysiological correlates of emotional language perception are sensitive to both top-down and bottom-up processes.

Age-Related Effects on Memory for Social Stimuli: The Role of Valence, Arousal, and Emotional Responses

Background/Study Context: Previous research (Hess et al., 2013, Psychology and Aging, 28, 853-863) suggested that age-based positivity effects in memory were attenuated with social stimuli. This research examined the degree to which this generalized across arousal levels associated with social images. Variations in approach and avoidance responses to individual images were also examined, along with age differences in their relationship to memory performance.

METHODS

In Experiment 1, young (22-43 years) and older (65-85 years) adults recalled positive and negative social scenes that were high or low in arousal. In Experiment 2, young (20-40 years) and older (65-83 years) adults viewed and recalled the same scenes under instructions designed to alter arousal, and approach and avoidance ratings for each image were recorded.

RESULTS

In Experiment 1, age differences in recall were confined to high-arousal, negative images, with young adults exhibiting superior memory relative to older adults. There was no evidence of an age-related positivity effect for low-arousal social scenes. This result was replicated in Experiment 2, but distancing instructions minimized the age difference in recall for high-arousal, negative images. Approach and avoidance ratings differentially predicted recall across age groups, with stronger associations in the young.

CONCLUSION

The results are consistent with emerging evidence demonstrating that valence-based biases associated with aging (e.g., positivity effect) are specific to the context and stimulus characteristics. Differences in prediction of recall responses from approach and avoidance ratings across age groups suggested that the observed effects in memory reflected differences in responses to the characteristics of stimuli.

Exposure to Poverty and Productivity

We study whether exposure to poverty can induce affective states that decrease productivity. In a controlled laboratory setting, we find that subjects randomly assigned to a treatment, in which they view a video featuring individuals that live in extreme poverty, exhibit lower subsequent productivity compared to subjects assigned to a control treatment. Questionnaire responses, as well as facial recognition software, provide quantitative measures of the affective state evoked by the two treatments. Subjects exposed to images of poverty experience a more negative affective state than those in the control treatment. Further analysis shows that individuals in a more positive emotional state exhibit less of a treatment effect. Also, those who exhibit greater attentiveness upon viewing the poverty video are less productive. The results are consistent with the notion that exposure to poverty can induce a psychological state in individuals that adversely affects productivity.

Low Arousing Positive Affect Broadens Visual Attention and Alters the Thought-Action Repertoire While Broadened Visual Attention Does Not

The Broaden-and-Build Theory states that positive emotions broaden cognition and therefore build personal resources. However, missing theoretical precision regarding the interaction of the cognitive processes involved offers a variety of possible explanations for the mechanisms of broadening and building. In Experiment 1 we tested the causality assumption which states that positive emotions first broaden visual attention which in turn leads to broadened cognition. We examined the effects of a broadened, narrowed or neutral attentional scope of 72 subjects (30 men) on their momentary thought-action repertoire. Results showed that there were no significant differences between groups regarding the breadth or the content of the thought-action repertoire. In Experiment 2 we studied the non-causality hypothesis which assumes a non-causal relationship between cognitive processes. We did so by investigating the effects of negative, neutral, and positive affect on the visual attentional scope of 85 subjects (41 men) in Experiment 2a, as well as on the thought-action repertoire of 85 participants (42 men) in Experiment 2b. Results revealed an attentional broadening effect in Experiment 2a but no differences between groups concerning the breadth of the thought-action repertoire in Experiment 2b. However, a theory driven content analysis showed that positive affect promoted social actions. Thus, our results favor the non-causality assumption. Moreover, results indicate that positive emotions do not target personal resources in general but rather resources associated with social behavior. In conclusion, we argue that the Broaden-and-Build Theory should be refined.

Classroom-Based Physical Activity Breaks and Children's Attention: Cognitive Engagement Works!

Classroom-based physical activity breaks are postulated to positively impact children's attention during their school day. However, empirical evidence for this claim is scarce and the role of cognitive engagement in enhancing children's attentional performance is unexplored in studies on physical activity breaks. The aim of the present study was therefore to disentangle the separate and/or combined effects of physical exertion and cognitive engagement induced by physical activity breaks on primary school children's attention. In addition, the role of children's affective reactions to acute interventions at school was investigated. Using a 2 × 2 between-subjects experimental design, 92 children between the ages of 11 and 12 years (M = 11.77, SD = 0.41) were randomly assigned to one of four experimental conditions: (1) combo group (physical activity with high cognitive demands), (2) cognition group (sedentary with high cognitive demands), (3) physical group (physical activity with low cognitive demands), and (4) control group (sedentary with low cognitive demands). Attention and affect were measured before and immediately after a 10-min intervention. ANCOVAs revealed that whereas physical exertion had no effect on any measure of children's attentional performance, cognitive engagement was the crucial factor leading to increased focused attention and enhanced processing speed. Mediational analyses showed that changes in positive affect during the interventions mediated the effect between cognitive engagement and focused attention as well as between cognitive engagement and processing speed. These surprising results are discussed in the light of theories predicting both facilitating and deteriorative effects of positive affect on attention.

Affective bias in visual working memory is associated with capacity

How does the affective nature of task stimuli modulate working memory (WM)? This study investigates whether WM maintains emotional information in a biased manner to meet the motivational principle of approaching positivity and avoiding negativity by retaining more approach-related positive content over avoidance-related negative content. This bias may exist regardless of individual differences in WM functionality, as indexed by WM capacity (overall bias hypothesis). Alternatively, this bias may be contingent on WM capacity (capacity-based hypothesis), in which a better WM system may be more likely to reveal an adaptive bias. In two experiments, participants performed change localisation tasks with emotional and non-emotional stimuli to estimate the number of items that they could retain for each of those stimuli. Although participants did not seem to remember one type of emotional content (e.g. happy faces) better than the other type of emotional content (e.g. sad faces), there was a significant correlation between WM capacity and affective bias. Specifically, participants with higher WM capacity for non-emotional stimuli (colours or line-drawing symbols) tended to maintain more happy faces over sad faces. These findings demonstrated the presence of a "built-in" affective bias in WM as a function of its systematic limitations, favouring the capacity-based hypothesis.
