Contributors to suicidal ideation among bipolar patients with and without a history of suicide attempts

This study was designed to develop models for vulnerability to suicidal ideation in bipolar patients. Logistic regression models examined correlates of suicidal ideation in patients who had versus had not attempted suicide previously. Of 477 patients assessed, complete data on demographic, illness history, and personality variables were available on 243. The regression models achieved positive predictive values of 55% and 59% for the attempter (N = 92) and nonattempter groups (N = 151), respectively. Depression was cross-sectionally associated with suicidal ideation in both the attempter and nonattempter groups but made a smaller contribution among attempters. Poor psychosocial adaptation and the personality factor "openness" were stronger contributors to suicidal ideation among prior attempters while anxiety and extraversion appeared protective against ideation. Among nonattempters, depression, anxiety, and neuroticism were the predominant influences on suicidal ideation. Bipolar patients with suicidal ideation may benefit from different treatment strategies depending on their prior attempt status.     

Nancy J. Hirschmann on the Social Construction of Women's Freedom

Nancy J. Hirschmann presents a feminist, social constructionist account of women's freedom. Friedman's discussion of Hirschmanns account deals with (1) some conceptual problems facing a thoroughgoing social constructionism; (2) three ways to modify social constructionism to avoid those problems; and (3) an assessment of Hirschmann's version of social constructionism in light of the previous discussion.     

An index of self-regulation of emotion and the study of repression in social contexts that threaten or do not threaten self-concept

This research tests a model of repression (M. Mendolia, 1999; M. Mendolia, J. Moore, & A. Tesser, 1996) which specifies that the interaction of individual differences in emotional responsiveness and situational threats to self-concept contributes to one's tendency to regulate emotional responsiveness. This research demonstrates that (a) individuals regulate their autonomic activity, facial muscle activity, cognitive attention, and subjective experience during isolated and repeated exposures to self-threatening negative and positive emotional events and (b) repressive behavior can be predicted by the Index of Self-Regulation of Emotion, which complements and extends conventional categorical measures of dispositional repression. This model provides a more detailed understanding of basic mechanisms in emotion by identifying how individual differences in emotionality and particular social contexts contribute to self-regulation of emotion.     

Multimodal signal detection: Independent decisions vs. integration

The pooling of information from simultaneous, spatially congruent auditory and visual stimuli is examined in a signal detection task. The paradigm used permits discrimination among a number of models of the decision mechanisms involved in processing multiple component stimuli. Parameter-free predictions are presented for the weighted integration model and for three versions of the independent decisions model. The data support an independent decisions model of the bimodal detection process in which attention is shared equally between modalities.     

Facial dynamics as indicators of trustworthiness and cooperative behavior

Detecting cooperative partners in situations that have financial stakes is crucial to successful social exchange. The authors tested whether humans are sensitive to subtle facial dynamics of counterparts when deciding whether to trust and cooperate. Participants played a 2-person trust game before which the facial dynamics of the other player were manipulated using brief (<6 s) but highly realistic facial animations. Results showed that facial dynamics significantly influenced participants' (a) choice of with whom to play the game and (b) decisions to cooperate. It was also found that inferences about the other player's trustworthiness mediated these effects of facial dynamics on cooperative behavior.
