Altered Cortico-Limbic Functional Connectivity During an Empathy Task in Subjects with Post-Traumatic Stress Disorder

Empathy is a multidimensional construct consisting of cognitive (inferring mental states) and emotional (empathic concern) components. Emotional empathy is severely impaired in individuals affected by Post-Traumatic Stress Disorder (PTSD). Here, we investigated the neural correlates of such an emotional empathy dysfunction to shed light on the neural circuitry responsible for the social and emotional dysfunction in PTSD. We asked a group of PTSD and a group of healthy controls to solve a Multifaceted Empathy Test, measuring both cognitive and emotional empathy, and investigated the functional connectivity of the cortical areas involved in solving the test. The results revealed that, in healthy individuals, increased neural activity in the frontal cortex modulates activity in the insula while subjects perform the emotional empathy task; whereas, in individuals affected by PTSD, increased activity in limbic regions such the insula and the amygdala modulates activity in the frontal cortex while performing the emotional empathy task. These findings suggest that the lack of cortical top-down control of the frontal cortex on the limbic system in PTSD during empathic processing may explain the emotional and social difficulties experienced by individuals suffering from PTSD.     

The Relationship Between Gender Social Identity and Support for Feminism

This study is an application of social identity theory to feminist consciousness and activism. For women, strong gender identifications may enhance support for equality struggles, whereas for men, they may contribute to backlashes against feminism. University students (N = 276), primarily Euroamerican, completed a measure of gender self-esteem (GSE, that part of one's self-concept derived from one's gender), and two measures of feminism. High GSE in women and low GSE in men were related to support for feminism. Consistent with past research, women were more supportive of feminism than men, and in both genders, support for feminist ideas was greater than self-identification as a feminist.     

The Undoing Effect of Positive Emotions

Positive emotions are hypothesized to undo the cardiovascular aftereffects of negative emotions. Study 1 tests this undoing effect. Participants (n = 170) experiencing anxiety-induced cardiovascular reactivity viewed a film that elicited (a) contentment, (b) amusement, (c) neutrality, or (d) sadness. Contentment-eliciting and amusing films produced faster cardiovascular recovery than neutral or sad films did. Participants in Study 2 (n = 185) viewed these same films following a neutral state. Results disconfirm the alternative explanation that the undoing effect reflects a simple replacement process. Findings are contextualized by Fredrickson's broaden-and-build theory of positive emotions (B. L. Fredrickson, 1998).     

Comprehensive community-based education and neurorehabilitation for children and adolescents with traumatic brain injury

Children and adolescents who experience a traumatic brain injury (TBI) typically have sensory, cognitive, behavioral, and functional skill challenges that must be addressed in acute and post-acute rehabilitation settings. This article describes a community-based school that combines educational, medical, nursing, family, residential-living, and psychological services in a comprehensive program of pediatric neurorehabilitation. The operational, administrative, and clinical features of these service components are presented. A critical aspect of the program is an emphasis on applied behavior analysis procedures for purposes of assessment, treatment formulation, and evaluation. Data are reviewed to demonstrate demographics, patterns of service delivery, and outcome. The school program represents an educational alternative for students with TBI who are discharged from acute-care settings and require comprehensive support services to facilitate their transition and re-entry to public school and community living. © 1998 John Wiley & Sons, Ltd.     

Abusive supervision,leader-member exchange,and moral disengagement: A moderated-mediation model of organizational deviance

This paper draws from social exchange theory and social cognitive theory to explore moral disengagement as a potential mediator of the relationship between abusive supervision and organizational deviance. We also explore the moderating effect of leader-member exchange (LMX) on this mediated relationship. Results indicate that employees with abusive supervisors engaged in moral disengagement strategies and subsequently in organizational deviance behaviors. Additionally, this relationship was stronger for those higher in LMX. Important implications for management research and practice are discussed.     

Response latency as a measure of behavior in the assessment of elopement

Elopement is a common form of problem behavior but is relatively underrepresented in the functional analysis literature. One barrier to assessing elopement experimentally is the need to retrieve the subject following an instance of elopement. This retrieval confounds programmed session contingencies when the goal is to obtain repeated measurement of free‐operant behavior. The current study evaluated latency to elopement as an alternative to free‐operant measurement. We first compared response latency to allocation in 5‐min sessions and then measured latency alone in a trial‐based format. The identified reinforcers matched across both data analysis modalities in the session‐based assessments, and the trial‐based functional analysis showed a significant time savings in identifying the function of behavior over a session‐based assessment. Results indicated that elopement serves idiosyncratic social functions in young children with intellectual and developmental disabilities, and that a latency‐based assessment saves time while yielding equally clear results.     

Organizational Politics and Deviance: Exploring the Role of Political Skill

Building on social exchange theory, this study examines the relationship between perceptions of organizational politics and employee performance and interpersonal skills. We hypothesized that perceptions of organizational politics create an imbalance in the exchange relationship between employee and organization, which leads to organizational deviance. We also hypothesized that supervisors may attempt to rebalance the exchange relationship by providing lower performance and interpersonal skills ratings. Finally, we suggest that politically skilled employees avoid an increase in negative ratings. The present study demonstrates that perceptions of organizational politics may lead to negative employee behaviors and reduced supervisors’ ratings in an effort to rebalance the exchange relationship. In addition, politically skilled employees may avoid increased negative ratings when politics perceptions are high.     

And one more for the road: Commentary on the Special Issue on alcohol and eyewitness memory

Studies examining the influence of alcohol intoxication have reported mixed findings on whether it impairs eyewitness memory. Although the studies in this Special Issue investigated different questions and tested different variables, the findings of these studies collectively provide insight into mechanisms and methodological issues that may explain the ambiguous findings of alcohol intoxication and eyewitness memory. In this commentary, we first describe the experimental studies of this Special Issue. We then discuss four mechanisms that could underlie those mixed findings (alcohol myopia, disinhibition, hypervigilance, and metacognitive processes at retrieval). Last, we address methodological issues that may have contributed to those ambiguous findings (i.e., alcohol intoxication levels, automatic processing of stimuli, sensitivity of dependent variables, and possible interactions with arousal) and provide suggestions for future research to address these issues.
