Is happiness a cure-all for mental fatigue?: mood interacts with situational requirements in predicting performance

There is a set of competing theories for how emotion influences behavior after being psychologically challenged. One group of theories emphasize that positive affect enhances performance after a psychological challenge. Conversely, the emotion and goal compatibility theory argues that positive and negative emotions can enhance or reduce performance and motivation to control behavior depending on the task requirements. To test these contrasting predictions, participants were psychologically challenged by completing a Stroop task and then induced into a positive, negative, or neutral mood. A verbal or spatial working memory task was then completed to assess performance and motivation to control behavior. As predicted, positive mood benefited performance and behavioral control on the verbal working memory task, whereas, a negative mood benefited performance and behavioral control on the spatial working memory task. Thus, following a psychological challenge motivation to control behavior depended on interactions between mood and task requirements consistent with the emotion and goal compatibility theory.

Lots to Do or Lots of Ways to Do It? The Role of Mood and Mind‐set on Goal Motivation

This research explores how mood interacts with outcome and implemental mind‐sets to influence motivation to work toward a goal. We propose and demonstrate that being in a positive (vs. neutral) mood increases motivation for those in an outcome mind‐set. Conversely, being in a positive (vs. neutral) mood decreases motivation for those in an implemental mind‐set. We argue that the reason for this is rooted in the role of positive mood on the number of available goal attainment means: Positive (vs. neutral) mood was found to increase the number of accessible goal attainment activities. For those in an outcome mind‐set, the increased number of goal attainment activities increases motivation because more activities are perceived as more available opportunities or strategies that may aid in successful goal attainment. For those in an implemental mind‐set, where one considers detailed steps and processes required for goal completion, motivation is decreased, because availability of more activities increases perceived difficulty of goal execution. Five studies support these hypotheses, showing differences in available activities depending on mood, differences in perceptions of those activities depending on mind‐set, and differences in motivation depending on the interaction of mood and mind‐set.     

情绪状态对不同年龄儿童定势转换的影响

采用情绪影片引发情绪的方法,考察64名8~12岁儿童在正负情绪状态下定势转换能力的表现。研究为4(年龄)×2(情绪)×3(重复转换条件:重复、短时转换、长时转换)3因素重复测量混合设计。结果表明,情绪状态对任务转换产生了影响,可能是积极情绪比消极情绪对任务定势的长时转换削弱更大。不同年龄的儿童在这两种任务转换条件中没有出现显著的年龄差异,说明8~12岁儿童均已具备在两个任务之间进行即时转换的能力。     

Happiness increases verbal and spatial working memory capacity where sadness does not: Emotion,working memory and executive control

The effects of emotion on working memory and executive control are often studied in isolation. Positive mood enhances verbal and impairs spatial working memory, whereas negative mood enhances spatial and impairs verbal working memory. Moreover, positive mood enhances executive control, whereas negative mood has little influence. We examined how emotion influences verbal and spatial working memory capacity, which requires executive control to coordinate between holding information in working memory and completing a secondary task. We predicted that positive mood would improve both verbal and spatial working memory capacity because of its influence on executive control. Positive, negative and neutral moods were induced followed by completing a verbal (Experiment 1) or spatial (Experiment 2) working memory operation span task to assess working memory capacity. Positive mood enhanced working memory capacity irrespective of the working memory domain, whereas negative mood had no influence on performance. Thus, positive mood was more successful holding information in working memory while processing task-irrelevant information, suggesting that the influence mood has on executive control supersedes the independent effects mood has on domain-specific working memory.     

For love or money? What motivates people to know the minds of others?

Mood affects social cognition and "theory of mind", such that people in a persistent negative mood (i.e., dysphoria) have enhanced abilities at making subtle judgements about others' mental states. Theorists have argued that this hypersensitivity to subtle social cues may have adaptive significance in terms of solving interpersonal problems and/or minimising social risk. We tested whether increasing the social salience of a theory of mind task would preferentially increase dyspshoric individuals' performance on the task. Forty-four dysphoric and 51 non-dysphoric undergraduate women participated in a theory of mind decoding task following one of three motivational manipulations: (i) social motivation (ii) monetary motivation, or (iii) no motivation. Social motivation was associated with the greatest accuracy of mental state decoding for the dysphoric group, whereas the non-dysphoric group showed the highest accuracy in the monetary motivation condition. These results suggest that dysphoric individuals may be especially, and preferentially, motivated to understand the mental states of others.     

Réguler ses émotions quand on apprend,oui mais pourquoi ? Motivations à réguler ses émotions,buts émotionnels et stratégies de régulation émotionnelle mises en œuvre par des étudiants universitaires primo-arrivants en situation de préparation d’examen

Studying for the first exam period is a big challenge for freshmen students, especially because they must be able to regulate emotions emerging from this new learning situation. Indeed, it is now recognized that cognitions and emotions interact in learning and that emotion can hinder or support it. However, we argue that it is not only emotions per se but rather how students manage them in the targeted situation (i.e. their emotional regulation skills) that impacts students’ adaptation to this academic context. Using an online survey, this study explored motives in emotion regulation, emotion goals and concrete emotion regulation strategies implemented by students during the preparation of a significant course evaluation. It focuses both on “why” students engage in emotion regulation in the target situation and on “how” this regulation is implemented. A thematic content analysis, processing the data of the 235 respondents, indicates that different motivations in emotion regulation are present among students (hedonic and instrumental motivations to regulate emotions) and that these motivations can be plural among the same students. When instrumental and hedonic motivations are both reported, although the students’ discourse argues that hedonic motivation (feeling good/better) is at the service of instrumental motivation (studying the course), concrete SRE prioritize well-being, through distraction from the course, more than the study of the course (the SRE rarely supports learning). In addition, the most reported emotion regulation strategy is distraction from the course (taking a break and doing something to distract yourself from the course), even in the absence of motivational conflicts. As a result, the theoretical model of motivated regulation (Tamir, 2009; Tamir, 2015) applied to this learning situation offers an innovative reading of why and how university students attempt to manage their emotions in order to learn successfully. Although the current study approaches only the conscious side of emotion regulation, it provides an original perspective on this complex phenomenon without ignoring the context in which it emerges. Finally, this insight should help students, teachers and educational coaches to see emotion regulation as necessary for learning and to set up pedagogical and coaching practices that support the development of SRE, adapted to the learning situation and linked to the emotional states that students wish to experiment in order to optimize learning.     

Understanding the relationship between mood and creativity: A meta-analysis

A meta-analysis of 62 experimental and 10 non-experimental studies was conducted to evaluate the positive-mood-enhances-creativity generalization. While the results demonstrate that positive mood enhances creativity, the strength of that effect is contingent upon the comparative or referent mood state (i.e., neutral or negative mood) as well as the type of creative task. Further, the pattern of effect sizes supports a curvilinear relationship between affective intensity and creative performance. In general, a contextual perspective of mood–creativity relations is supported.     

The cognitive regulation of emotions: The role of success versus failure experience and coping dispositions

Attention deployment and generating specific types of cognitions are central cognitive mechanisms of emotion regulation. Two groups of hypotheses make contradicting predictions about the emotion-cognition relationship. The moodcongruency hypothesis expects the emergence of mood-congruent cognitions (i.e., negative mood leads to negative and positive mood to positive cognitions). Similarly, a substantial body of research suggests that negative mood induces selffocus, whereas positive mood elicits an external focus of attention. The moodrepair hypothesis, on the other hand, assumes that persons in a negative mood state summon thoughts incongruent with that state and divert attention away from the self. However, the temporal sequence of cognitions assessed as well as coping dispositions, such as vigilance and cognitive avoidance, may moderate these relationships. Positive and negative emotional states were elicited by exposing the participants to the experience of success or failure in a demanding cognitive task. Cognitions that were present after emotion induction were assessed by means of a thought-listing procedure. For the total sample, results clearly confirmed the moodcongruency hypothesis. Thought order was a critical factor only for changes in self-focus. Thought valence (positive, neutral, negative) as well as self-focus were substantially influenced by coping dispositions.     

Dissociable influences of reward motivation and positive emotion on cognitive control

It is becoming increasingly appreciated that affective and/or motivational influences contribute strongly to goal-oriented cognition and behavior. An unresolved question is whether emotional manipulations (i.e., direct induction of affectively valenced subjective experience) and motivational manipulations (e.g., delivery of performance-contingent rewards and punishments) have similar or distinct effects on cognitive control. Prior work has suggested that reward motivation can reliably enhance a proactive mode of cognitive control, whereas other evidence is suggestive that positive emotion improves cognitive flexibility, but reduces proactive control. However, a limitation of the prior research is that reward motivation and positive emotion have largely been studied independently. Here, we directly compared the effects of positive emotion and reward motivation on cognitive control with a tightly matched, within-subjects design, using the AX-continuous performance task paradigm, which allows for relative measurement of proactive versus reactive cognitive control. High-resolution pupillometry was employed as a secondary measure of cognitive dynamics during task performance. Robust increases in behavioral and pupillometric indices of proactive control were observed with reward motivation. The effects of positive emotion were much weaker, but if anything, also reflected enhancement of proactive control, a pattern that diverges from some prior findings. These results indicate that reward motivation has robust influences on cognitive control, while also highlighting the complexity and heterogeneity of positive-emotion effects. The findings are discussed in terms of potential neurobiological mechanisms.     

Conflict-driven adaptive control is enhanced by integral negative emotion on a short time scale*

ABSTRACT

Negative emotion influences cognitive control, and more specifically conflict adaptation. However, discrepant results have often been reported in the literature. In this study, we broke down negative emotion into integral and incidental components using a modern motivation-based framework, and assessed whether the former could change conflict adaptation. In the first experiment, we manipulated the duration of the inter-trial-interval (ITI) to assess the actual time-scale of this effect. Integral negative emotion was induced by using loss-related feedback contingent on task performance, and measured at the subjective and physiological levels. Results showed that conflict-driven adaptive control was enhanced when integral negative emotion was elicited, compared to a control condition without changes in defensive motivation. Importantly, this effect was only found when a short, as opposed to long ITI was used, suggesting that it had a short time scale. In the second experiment, we controlled for effects of feature repetition and contingency learning, and replicated an enhanced conflict adaptation effect when integral negative emotion was elicited and a short ITI was used. We interpret these new results against a standard cognitive control framework assuming that integral negative emotion amplifies specific control signals transiently, and in turn enhances conflict adaptation.     

The joint effect of informational mood impact and performance-contingent consequences on effort-related cardiovascular response

Drawing on the mood-behavior model (G. H. E. Gendolla, 2000) and J. W. Brehm and E. A. Self's (1989) theory of effort mobilization, 2 experiments investigated the joint effect of mood, task difficulty, and performance-contingent consequences on effort-related cardiovascular response. Informational mood impact on demand appraisals and performance-contingent consequences had a joint effect on effort mobilization. When consequences were noncontingent on performance, mood interacted with task difficulty to determine cardiovascular reactivity in the shape of a cross-over interaction pattern. Yet when positive consequences were performance contingent, cardiovascular reactivity strongly increased only in the negative-mood/difficult-task condition--the subjectively appraised high necessary effort was now justified. Implications for the role of mood in motivation are discussed.     

Positive emotion dysregulation across mood disorders: How amplifying versus dampening predicts emotional reactivity and illness course

Maladaptive regulation of positive emotion has increasingly been associated with psychopathology. Little is known, however, about how individual strategies used to manage positive emotion predict concurrent emotional responding and prospective illness course across mood disorders. The present study examined the concurrent and prospective influence of amplification and dampening regulation strategies of positive emotion (i.e., self-focused positive rumination, emotion-focused positive rumination, and dampening) among remitted individuals with bipolar I disorder (BD; n = 31) and major depressive disorder (MDD; n = 31). Rumination over positive emotional states concurrently predicted increased positive emotion across both mood disordered groups during an experimental rumination induction. However, dampening positive emotion concurrently predicted increased emotional reactivity (i.e., heart rate and negative affect) and prospective increases in manic and depressive symptoms for the BD group only. This suggests that amplifying positive emotion transdiagnostically increases positive emotion across mood disordered groups, while attempts to dampen positive emotion may paradoxically exacerbate emotional reactivity and illness course in BD. For individuals with BD, negative thinking about one's positive emotion (via dampening) may be particularly maladaptive.     

Mood effects on emotion recognition

Mood affects memory and social judgments. However, findings are inconsistent with regard to how mood affects emotion recognition: For sad moods, general performance decrements in emotion recognition have been reported, as well as an emotion specific bias, such as better recognition of sad facial expressions compared to happy expressions (negative bias). Far less research has been conducted on the influence of happy moods on emotion recognition. We primed 93 participants with happy, sad, or neutral moods and had them perform an emotion recognition task. Results showed a negative bias for participants in sad moods and a positive bias for participants in happy moods. Sad and happy moods hampered the recognition of mood-incongruent expressions; the recognition of mood-congruent expressions was not affected by moods.     

Positive and negative affect produce opposing task-irrelevant stimulus preexposure effects

In three experiments, groups were exposed to either positive or negative affect video clips, after which they were presented with a series of task-irrelevant stimuli. In the subsequent test task, subjects were required to learn an association between the previously irrelevant stimulus and a consequence, and between a new stimulus and a consequence. Induced positive affect produced a latent inhibition effect (poorer evidence of learning with the previously irrelevant stimulus than with the novel stimulus). In opposition to this, induced negative affect resulted in better evidence of learning with a previously irrelevant stimulus than with a novel stimulus. In general, the opposing effects also were present in participants scoring high on self-report questionnaires of depression (Experiments 2 and 3). These unique findings were predicted and accounted for on the basis of two principles: (a) positive affect broadens the attentional field and negative affect contracts it; and (b) task-irrelevant stimuli are processed in two successive stages, the first encodes stimulus properties, and the second encodes stimulus relationships. The opposing influences of negative and positive mood on the processing of irrelevant stimuli have implications for the role of emotion in general theories of cognition, and possibly for resolving some of the inconsistent findings in research with schizophrenia patients.     

On bad mood and white bears: The effects of mood state on ability to suppress unwanted thoughts

Does temporary mood influence people's ability to engage in effective thought suppression? Based on past research on mental control and recent work on affective influences on social cognition, this experiment predicted and found that negative mood improved and positive mood impaired people's ability to suppress their thoughts when instructed not to think of a neutral concept, white bears. We also found clear evidence for ironic rebound effects: on a subsequent generative task, intrusions of the suppressed thought were greater in the negative than in the positive mood group. Participants received positive or negative feedback about performance on a supposed creativity task to induce positive or negative moods, and then engaged in two consecutive generative writing tasks, the first accompanied by instructions to suppress thoughts of white bears. Those in a negative group reported fewer “white bear” intrusions when attempting to suppress, but more “white bear” intrusions (an ironic rebound effect) in the subsequent task when the suppression instruction was lifted. The implications of these results for everyday tasks of mental control, and for recent affect–cognition theories are discussed.     

Happiness increases distraction by auditory deviant stimuli

Rare and unexpected changes (deviants) in an otherwise repeated stream of task‐irrelevant auditory distractors (standards) capture attention and impair behavioural performance in an ongoing visual task. Recent evidence indicates that this effect is increased by sadness in a task involving neutral stimuli. We tested the hypothesis that such effect may not be limited to negative emotions but reflect a general depletion of attentional resources by examining whether a positive emotion (happiness) would increase deviance distraction too. Prior to performing an auditory‐visual oddball task, happiness or a neutral mood was induced in participants by means of the exposure to music and the recollection of an autobiographical event. Results from the oddball task showed significantly larger deviance distraction following the induction of happiness. Interestingly, the small amount of distraction typically observed on the standard trial following a deviant trial (post‐deviance distraction) was not increased by happiness. We speculate that happiness might interfere with the disengagement of attention from the deviant sound back towards the target stimulus (through the depletion of cognitive resources and/or mind wandering) but help subsequent cognitive control to recover from distraction.     

The Interaction of Mood and Rumination in Depression: Effects on Mood Maintenance and Mood-Congruent Autobiographical Memory

Rumination is a response to distress in which individuals focus repetitively on their feelings and the causes and consequences of those feelings. When induced to ruminate, dysphorics exhibit more negative mood and recall more negative memories, but these effects are not seen in nondysphorics. This pattern of results could be due to trait-like differences between dysphoric and nondysphoric individuals, or to the high levels of negative affect that dysphorics are experiencing at the time of rumination. The purpose of this study was to evaluate the effects of pre-rumination mood on post-rumination mood and subsequent memory. Participants scoring high or low in depressive symptoms were assigned to either a positive or negative emotion induction prior to ruminating and completing an autobiographical memory task. Analysis of self-reported mood indicates that both emotion inductions were effective. Surprisingly, all participants returned to baseline mood levels following the rumination induction, and emotion induction had no effect on the negativity of the memories recalled. Dysphorics recalled significantly more negative memories than nondysphorics, regardless of whether positive, neutral, or negative memories were specifically prompted. Our results indicated that the prolonged experience of dysphoria may have greater effects on post-rumination mood and memory than the transitory experience of sadness.     

Mood and the Quantity and Quality of Ideas

Two positions concerning positive mood and its relation to creative problem solving have been taken. The general position (GP) postulates that there is a consistent positive relation between positive mood and creative problem solving. The qualified position (QP) states that the relation is a contingent one. This study explores one possible limitation to the GP, by testing Weisberg's (1994) suggestion that positive mood facilitates productivity but not quality of ideas. Self-reported mood was measured by positive, negative, and arousal scales. Divergent thinking tasks scored for fluency, flexibility, originality, and usefulness were used as criterion variables. A perfect, theoretically predicted rank order between positive mood and degree of solution constraint measured by the divergent thinking indices emerged. Positive mood was significantly related to an idea quantity factor but not to an idea quality factor. Although this evidence is not conclusive, it supports the QP and indicates that the GP should be modified to include task type and degree of solution constraint.

On being happy but fearing failure: The effects of mood on self-handicapping strategies

Does temporary mood influence people’s tendency to engage in self-handicapping behaviors? Based on past research on self-handicapping and recent work on affect and social behaviors, this experiment predicted and found that positive mood significantly increased the tendency to engage in two kinds of self-handicapping strategies. Participants (N = 94) first received contingent or non-contingent positive feedback about performance on a task of ‘cognitive abilities’, and then underwent a positive, neutral, or negative mood induction using video films. Self-handicapping was assessed in terms of their subsequent preference for (a) drinking a performance-enhancing, or performance-inhibiting herbal tea, and (b) engaging or not engaging in performance-enhancing cognitive practice. As predicted, happy mood and non-contingent feedback significantly increased self-handicapping on both measures. The implications of these results for everyday performance tasks, and for recent affect-cognition theories, are discussed.
