Neural correlates of intertemporal choice in aggressive behavior

People often have to make decisions between immediate rewards and more long-term goals. Such intertemporal judgments are often investigated in the context of monetary choice or drug use, yet not in regard to aggressive behavior. We combined a novel intertemporal aggression paradigm with functional neuroimaging to examine the role of temporal delay in aggressive behavior and the neural correlates thereof. Sixty-one participants (aged 18–22 years; 37 females) exhibited substantial variability in the extent to which they selected immediate acts of lesser aggression versus delayed acts of greater aggression against a same-sex opponent. Choosing delayed-yet-more-severe aggression was increased by provocation and associated with greater self-control. Preferences for delayed aggression were associated with greater activity in the ventromedial prefrontal cortex (VMPFC) during such choices, and reduced functional connectivity between the VMPFC and brain regions implicated in motor impulsivity. Preferences for immediate aggression were associated with reduced functional connectivity between the VMPFC and the frontoparietal control network. Dispositionally aggressive participants exhibited reduced VMPFC activity, which partially explained and suppressed their preferences for delayed aggression. Blunted VMPFC activity may thus be a neural mechanism that promotes reactive aggression towards provocateurs among dispositionally aggressive individuals. These findings demonstrate the utility of an intertemporal framework for investigating aggression and provide further evidence for the similar underlying neurobiology between aggression and other rewarding behaviors.     

The promotion of self-forgiveness,responsibility, and willingness to make reparations through a workbook intervention

This study evaluated the effectiveness of a workbook intervention designed to promote self-forgiveness, acceptance of responsibility, and willingness to make amends/reparations in a university student sample. The intervention manual consisted of three parts: (a) promoting prosocial and responsible attitudes, (b) reducing barriers to self-forgiveness, and (c) promoting healthy thinking and behaviors. Outcome measures included acceptance of responsibility, motivation to make reparations, and state and trait self-forgiveness. Measures were administered pre-intervention and immediately post-intervention. Participants were randomly assigned to an intervention group (N = 50) or a control group (N = 43). The control group studied materials for their university courses instead of completing the intervention. Following the intervention, the intervention group had significantly a higher state and dispositional self-forgiveness post-test compared to the control group. Changes in acceptance of responsibility and willingness to make reparations did not reach statistical significance as compared to the control group.     

Prosocial thinkers and the social transmission of justice

Feeling the sting of another's injustice is a common human experience. We adopt a motivated information processing approach and explore how individual differences in social motives (e.g., high vs. low collectivism) and epistemic motives (e.g., high vs. low need for closure) drive individuals' evaluative and behavioral reactions to the just and unjust treatment of others. In two studies, one in the laboratory (N = 78) and one in the field (N = 163), we find that the justice treatment of others has a more profound influence on the attitudes and behaviors of prosocial thinkers, people who are chronically higher (vs. lower) in collectivism and lower (vs. higher) in the need for closure. In all, our results suggest that chronically higher collectivism and a lower need for closure work in concert to make another's justice relevant to personal judgment and behavior.     

The implicit cognition of reciprocal exchange: automatic retrieval of positive and negative experiences with partners in a prisoner's dilemma game

Models of reciprocity imply that cheater detection is an important prerequisite for successful social exchange. Considering the fundamental role of memory in reciprocal exchange, these theories lead to the prediction that memory for cheaters should be preferentially enhanced. Here, we examine whether information of a partner's previous behaviour in an interaction is automatically retrieved when encountering the face of a partner who previously cheated or cooperated. In two studies, participants played a sequential prisoner's dilemma game with cheaters and cooperative partners. Alternating with the game blocks, participants were asked to classify the smiling or angry facial expressions of cooperators and cheaters. Both experiments revealed congruence effects, reflecting faster identification of the smiles of cooperators (Experiments 1 and 2) and faster identification of the angry facial expressions of cheaters (Experiment 2). Our study provides evidence for the automatic retrieval of the partner's behaviour in the game, regardless of whether partners cheated or cooperated, and thus provides further evidence against the cheater detection hypothesis.     

Feminism and Feminist Therapy: Lessons From the Past and Hopes for the Future

Feminist therapy incorporates the psychology of women (e.g., J. B. Miller, 1976), developmental research (e.g., C. Gilligan, 1982), cognitive‐behavioral techniques (J. Worell & P. Remer, 1992), multicultural awareness (L. Comas‐Diaz & B. Greene, 1994), and social activism (L. S. Brown, 1994) in a coherent theoretical and therapeutic package. It is an orientation that is effective in various venues and with diverse populations. In this article, the authors trace the relevant historical aspects of the orientation along with implications for practice, critiques, and trends.     

Making sense of male rape: constructions of gender,sexuality and experience of rape victims

This study reports a preliminary investigation into accounting practices for male rape in conversation. Thirty men and women, in dyads, were asked to discuss an incident of male rape presented to them in a vignette. The findings showed that two main issues were discussed: the experience of the rape act and societal responses to male victims. In addition, participants established a ‘hierarchy of suffering’, where rape was judged to be worse for ‘heterosexual’ men than it is for ‘women’ or ‘gay’ men. Hegemonic, phallocentric representations of heterosexuality were mobilized to argue that acts of rape and consensual intercourse are the same for ‘gay’ men and ‘women’ and therefore less traumatic than for ‘heterosexual’ men. This obscures the violence of rape for gay men and women and exonerates perpetrators by minimizing injury sustained. Participants also argued that heterosexual victims are likely to experience ridicule for having departed from hegemonic masculinity. Arguments were constructed to avoid charges of being dismissive towards women and gay men and of victim blaming in relation to heterosexual men. Copyright © 2004 John Wiley & Sons, Ltd.
