Delayed reconfiguration of a non-emotional task set through reactivation of an emotional task set in task switching: an ageing study

ABSTRACT

In our everyday life, we frequently switch between different tasks, a faculty that changes with age. However, it is still not understood how emotion impacts on age-related changes in task switching. Using faces with emotional and neutral expressions, Experiment 1 investigated younger (n?=?29; 18–38 years old) and older adults’ (n?=?32; 61–80 years old) ability to switch between an emotional and a non-emotional task (i.e. responding to the face's expression vs. age). In Experiment 2, younger and older adults also viewed emotional and neutral faces, but switched between two non-emotional tasks (i.e. responding to the face's age vs. gender). Data from Experiment 1 demonstrated that switching from an emotional to a non-emotional task was slower when the expression of the new face was emotional rather than neutral. This impairment was observed in both age groups. In contrast, Experiment 2 revealed that neither younger nor older adults were affected by block-wise irrelevant emotion when switching between two non-emotional tasks. Overall, the findings suggest that task-irrelevant emotion can impair task switching through reactivation of the competing emotional task set. They also suggest that this effect and the ability to shield task-switching performance from block-wise irrelevant emotion are preserved in ageing.     

Emotion regulation and risk taking: Predicting risky choice in deliberative decision making

Only very recently has research demonstrated that experimentally induced emotion regulation strategies (cognitive reappraisal and expressive suppression) affect risky choice (e.g., Heilman et al., 2010). However, it is unknown whether this effect also operates via habitual use of emotion regulation strategies in risky choice involving deliberative decision making. We investigated the role of habitual use of emotion regulation strategies in risky choice using the “cold” deliberative version of the Columbia Card Task (CCT; Figner et al., 2009). Fifty-three participants completed the Emotion Regulation Questionnaire (ERQ; Gross & John, 2003) and—one month later—the CCT and the PANAS. Greater habitual cognitive reappraisal use was related to increased risk taking, accompanied by decreased sensitivity to changes in probability and loss amount. Greater habitual expressive suppression use was related to decreased risk taking. The results show that habitual use of reappraisal and suppression strategies predict risk taking when decisions involve predominantly cognitive-deliberative processes.     

Echoing the emotions of others: empathy is related to how adults and children map emotion onto the body

ABSTRACT

Empathy involves a mapping between the emotions observed in others and those experienced in one’s self. However, effective social functioning also requires an ability to differentiate one’s own emotional state from that of others. Here, we sought to examine the relationship between trait measures of empathy and the self-other distinction during emotional experience in both children and adults. We used a topographical self-report method (emBODY tool) in which participants drew on a silhouette of a human body where they felt an emotional response while watching film and music clips, as well as where they believed the character in the film or performer was feeling an emotion. We then assessed how the degree of overlap between the bodily representation of self versus other emotions related to trait empathy. In adults, the degree of overlap in the body maps was correlated with Perspective Taking. This relationship between cognitive empathy and degree of overlap between self and other was also found with children (8–11 years old), even though children performed worse on the task overall. The results suggest that mapping emotions observed or imagined in other’s bodies onto our own is related to the development of empathy.     

Sex differences in the ability to recognise non-verbal displays of emotion: A meta-analysis

The present study aimed to quantify the magnitude of sex differences in humans' ability to accurately recognise non-verbal emotional displays. Studies of relevance were those that required explicit labelling of discrete emotions presented in the visual and/or auditory modality. A final set of 551 effect sizes from 215 samples was included in a multilevel meta-analysis. The results showed a small overall advantage in favour of females on emotion recognition tasks (d = 0.19). However, the magnitude of that sex difference was moderated by several factors, namely specific emotion, emotion type (negative, positive), sex of the actor, sensory modality (visual, audio, audio-visual) and age of the participants. Method of presentation (computer, slides, print, etc.), type of measurement (response time, accuracy) and year of publication did not significantly contribute to variance in effect sizes. These findings are discussed in the context of social and biological explanations of sex differences in emotion recognition.     

Encoding details: Positive emotion leads to memory broadening

In the current experiment we tested the hypothesis that unlike negative arousal, which leads to memory narrowing effects whereby an increase in memory for the central details is accompanied by a decrease in memory for the peripheral details, positive arousing events might lead to a memory broadening effect such that positive arousal would increase memory for both central and peripheral details. This was assessed by testing recognition for central and peripheral details of pictures that were selected to vary in a continuous manner across a wide range of arousal for both positive and negative items. The results indicated that increases in both positive and negative stimulus arousal levels led to gradual increases in memory for the central aspects of the photos. In contrast, negative arousal first increased then decreased memory for peripheral detail as arousal levels increased, whereas positive arousal led to a continuous increase in memory for peripheral details. Thus, arousing negative materials lead to memory narrowing, whereas arousing positive materials can lead to memory broadening.     

Differentiation of 13 positive emotions by appraisals

This research examined how strongly appraisals can differentiate positive emotions and how they differentiate positive emotions. Thirteen positive emotions were examined, namely, amusement, awe, challenge, compassion, contentment, gratitude, hope, interest, joy, pride, relief, romantic love and serenity. Participants from Singapore and the USA recalled an experience of each emotion and thereafter rated their appraisals of the experience. In general, the appraisals accurately classified the positive emotions at rates above chance levels, and the appraisal–emotion relationships conformed to predictions. Also, the appraisals were largely judged by participants as relevant to their positive emotion experiences, and the appraisal–emotion relationships were largely consistent across the two countries.     

How women's sexual orientation guides accuracy of interpersonal judgements of other women

This research examines how women's sexual orientation guides the accuracy of judgements of other women. One hundred ten judges (67 straight and 43 lesbian women) watched videotapes of 9 targets (4 straight and 5 lesbian) and made judgements about the targets' thoughts, emotions, personality, and sexual orientation. Accuracy scores were created for each judge by comparing judgements to criterion data gathered about targets. Straight judges were significantly more accurate at judging thoughts and marginally more accurate at judging emotions compared to lesbian judges. There were no significant differences in judging personality. Straight targets' thoughts and personality were more easily assessed than lesbian targets' while lesbians' emotions were more easily judged than straight targets'. Lesbian judges were more accurate at judging sexual orientation regardless of their tendency to categorize women as lesbian compared to straight judges. Findings support past research on the accurate perception of sexual orientation and contribute to understanding how sexual orientation guides person perception.     

Gratitude and depressive symptoms: The role of positive reframing and positive emotion

Eight studies (N=2,973) tested the theory that gratitude is related to fewer depressive symptoms through positive reframing and positive emotion. Study 1 found a direct path between gratitude and depressive symptoms. Studies 2–5 demonstrated that positive reframing mediated the relationship between gratitude and depressive symptoms. Studies 6–7 showed that positive emotion mediated the relationship between gratitude and depressive symptoms. Study 8 found that positive reframing and positive emotion simultaneously mediated the relationship between gratitude and depressive symptoms. In sum, these eight studies demonstrate that gratitude is related to fewer depressive symptoms, with positive reframing and positive emotion serving as mechanisms that account for this relationship.     

Embodied simulation as part of affective evaluation processes: Task dependence of valence concordant EMG activity

The current studies investigated age-related biases in recall of emotion in older and younger adults. In two prospective–retrospective, Internet-based diary studies, older (aged 65 years and older) and younger participants (aged 18 to 37) reported on their affect at the end of every day. Participants then recalled their affect during the diary rating periods. In both studies, recall bias was assessed by comparing retrospective reports to the prospective diary ratings. Older adults tended to overestimate positive affect more than younger adults, who themselves tended to overestimate negative affect more than older adults, relative to diary ratings. Age-related patterns of recall bias are discussed in light of recent literature on the interface between cognition and emotion in ageing, particularly on increased positivity and reduced negativity effects in emotional processing and recall.
