Smiling in the face of adversity: the interpersonal and intrapersonal functions of smiling

This study examined hypothesized interpersonal and intrapersonal functions of smiling in positive and negative affective contexts. Smiles were measured during a lab-based monologue task following either happy or sad emotion-evoking films. Psychological adjustment and social integration were measured longitudinally using data obtained in years prior to and after the experimental task. Duchenne (genuine) smiles predicted better long-term adjustment and this effect was mediated independently by both social integration and undoing of negative emotion during the monologue. These effects were observed only in the negative affective context. Non-Duchenne smiles were not related to psychological adjustment. Neither Duchenne nor non-Duchenne smiles during the monologue task were related to personality variables assessed in this study.     

Context matters: the benefits and costs of expressing positive emotion among survivors of childhood sexual abuse

Positive emotions promote adjustment to aversive life events. However, evolutionary theory and empirical research on trauma disclosure suggest that in the context of stigmatized events, expressing positive emotions might incur social costs. To test this thesis, the authors coded genuine (Duchenne) smiling and laughter and also non-Duchenne smiling from videotapes of late-adolescent and young adult women, approximately half with documented histories of childhood sexual abuse (CSA), as they described the most distressing event of their lives. Consistent with previous studies, genuine positive emotional expression was generally associated with better social adjustment two years later. However, as anticipated, CSA survivors who expressed positive emotion in the context of describing a past CSA experience had poorer long-term social adjustment, whereas CSA survivors who expressed positive emotion while describing a nonabuse experience had improved social adjustment. These findings suggest that the benefits of positive emotional expression may often be context specific.     

Loss and human resilience

In this article we argue that humans are more resilient in the face of loss than has been previously believed. We begin by showing that historically the bereavement literature has tended to pathologize what are otherwise normal and natural reactions to loss. We then introduce a characterization of resilience during bereavement as the ability to maintain continuity in identity from pre- to postloss. We review various types of evidence consistent with this proposal, with a particular emphasis on the relationship between resilience and continuity in social identity. We then explore four possible mechanisms by which resilient individuals achieve identity continuity. We also attempt to extend the resilience-as-continuity link to the recent literature on continued bonds with the deceased and explore how this link manifests across different cultures. Finally, we review some implications of these formulations for psychotherapy with bereaved individuals.     

The importance of being flexible: the ability to both enhance and suppress emotional expression predicts long-term adjustment

Researchers have documented the consequences of both expressing and suppressing emotion using between-subjects designs. It may be argued, however, that successful adaptation depends not so much on any one regulatory process, but on the ability to flexibly enhance or suppress emotional expression in accord with situational demands. We tested this hypothesis among New York City college students in the aftermath of the September 11th terrorist attacks. Subjects' performance in a laboratory task in which they enhanced emotional expression, suppressed emotional expression, and behaved normally on different trials was examined as a prospective predictor of their adjustment across the first two years of college. Results supported the flexibility hypothesis. A regression analysis controlling for initial distress and motivation and cognitive resources found that subjects who were better able to enhance and suppress the expression of emotion evidenced less distress by the end of the second year. Memory deficits were also observed for both the enhancement and the suppression tasks, suggesting that both processes require cognitive resources.     

When the face reveals what words do not: facial expressions of emotion,smiling, and the willingness to disclose childhood sexual abuse

For survivors of childhood sexual abuse (CSA), verbal disclosure is often complex and painful. The authors examined the voluntary disclosure-nondisclosure of CSA in relation to nonverbal expressions of emotion in the face. Consistent with hypotheses derived from recent theorizing about the moral nature of emotion, CSA survivors who did not voluntarily disclose CSA showed greater facial expressions of shame, whereas CSA survivors who voluntarily disclosed CSA expressed greater disgust. Expressions of disgust also signaled sexual abuse accompanied by violence. Consistent with recent theorizing about smiling behavior, CSA nondisclosers made more polite smiles, whereas nonabused participants expressed greater genuine positive emotion. Discussion addressed the implications of these findings for the study of disclosure of traumatic events, facial expression, and the links between morality and emotion.     

Differences in emotion modulation using cognitive reappraisal in individuals with and without suicidal ideation: An ERP study

Difficulties in emotion regulation have been associated with increased suicidal thoughts and behaviours. The majority of studies have examined self-reported use of emotion regulation strategies. In contrast, the current study focused on a direct measure of individuals’ ability to use a specific emotion regulation strategy, cognitive reappraisal, using the late positive potential (LPP), an event-related potential component that reflects attention to emotional stimuli. Specifically, the cognitive reappraisal ability of 33 undergraduate students was assessed via an image-viewing task during which the participants had to passively view, increase or reduce their emotions in response to looking at neutral, positive or dysphoric images. We found that participants with a history of suicidal ideation (SI) had significantly higher LPP when asked to reduce negative emotion in response to dysphoric images, compared to individuals with no history of SI. These findings suggest that difficulties with using cognitive reappraisal, specifically to decrease negative affect, might be linked to suicide risk.     

A Characterization of von Neumann Games in Terms of Memory

An information completion of an extensive game is obtained by extending the information partition of every player from the set of her decision nodes to the set of all nodes. The extended partition satisfies Memory of Past Knowledge (MPK) if at any node a player remembers what she knew at earlier nodes. It is shown that MPK can be satisfied in a game if and only if the game is von Neumann (vN) and satisfies memory at decision nodes (the restriction of MPK to a player's own decision nodes). A game is vN if any two decision nodes that belong to the same information set of a player have the same number of predecessors. By providing an axiom for MPK we also obtain a syntactic characterization of the said class of vN games.
