Predicting post‐traumatic growth and post‐traumatic stress in firefighters

Emergency service workers (e.g., firefighters, police, and paramedics) are exposed to elevated levels of potentially traumatising events through the course of their work. Such exposure can have lasting negative consequences (e.g., post‐traumatic stress disorder (PTSD)) and/or positive outcomes (e.g., post‐traumatic growth (PTG)). Research had implicated trauma, occupational and personal variables that account for variance in post‐trauma outcomes yet at this stage no research has investigated these factors and their relative influence on both PTSD and PTG in a single study. Based in Calhoun and Tedeschi's model of PTG and previous research, in this study regression models of PTG and PTSD symptoms among 218 firefighters were tested. Results indicated organisational factors predicted symptoms of PTSD, while there was partial support for the hypothesis that coping and social support would be predictors of PTG. Experiencing multiple sources of trauma, higher levels of organisational and operational stress, and utilising cognitive reappraisal coping were all significant predictors of PTSD symptoms. Increases in PTG were predicted by experiencing trauma from multiple sources and the use of self‐care coping. Results highlight the importance of organisational factors in the development of PTSD symptoms, and of individual factors for promoting PTG.     

Finding One’s Voice: Psychotherapy for Dissociative Motor Disorders in the Indian Context

Dissociation is a prevalent disorder in India, however there is a lack of evidence-based psychological interventions worldwide. The present paper includes two case studies of dissociative motor disorder with onset in the perinatal period, seeking treatment in the Indian tertiary mental health set-up. Both cases presented with disabling symptoms of paraparesis, and mutism in one. The case series discusses similarities in presentation, socio-cultural contexts, and the psychotherapeutic approach. The psychotherapy process is discussed in detail, with a focus on challenges encountered, therapist reflections and supervision. Insights from treatment are presented, including the melding of approaches, and sensitivity of interventions to the larger socio-cultural framework.

     

Implicit learning modulates selective attention at sensory levels of perceptual processing

Electrophysiological evidence suggests that attention can be modulated as early as 100 msec after stimulus presentation. However, it is not clear whether these changes are based primarily on stimulus properties such as perceptual load (i.e., the level of perceptual difficulty), or other properties, such as general attentional set or learned expectations concerning perceptual load. Using event-related potentials, this study examined how implicit learning of perceptual load conditions modulates selective attention at sensory levels of perceptual analysis. The results show significant differences in P1 amplitude recorded over occipital areas of the brain as a function of learned expectations of perceptual load, only when perceptual load could be reliably predicted by the preceding stimuli. Moreover, differences in processing were found when both low and high perceptual load conditions could be predicted. These findings suggest that implicit learning modulates the allocation of attention at early stages of perceptual processing.     

A Structural Social Psychological View of Gender Differences in Cooperation

We analyze differences in cooperation between men and women in social dilemma settings. Using a structural social psychological framework, we examine how the actor, the encounter, the microstructure, and the macrostructure might influence when gender differences emerge in cooperation. Many of the interaction differences, often linked to innate differences between men and women, are modified when the context is modified. We pay particular attention to how status and identity are connected to such modifications.     

Relationship between psychopathy and indirect aggression use in a noncriminal population

Psychopathy has long been associated with increased use of direct aggression and violence, especially among male inmates. Little research has, of yet, considered the relation between psychopathy and indirect forms of aggression. The current research sought to investigate the relationship between psychopathy and indirect aggression in a noncriminal sample. The results indicated that there was a strong relationship between psychopathic traits and indirect aggression, with strong correlations between indirect aggression and both factor 1 (coldheartedness) and factor 3 (impulsive antisociality). This association remained significant even after the effects of direct aggression had been controlled for. Path analysis indicated that both direct and indirect aggression was underpinned by the same psychopathy factors. This suggests that high psychopathy scorers will utilize direct and indirect aggression equally and, as such, the choice of one type of aggression over the other may be dependant on either situational factors or external moderators.

Distractor devaluation requires visual working memory

Visual stimuli seen previously as distractors in a visual search task are subsequently evaluated more negatively than those seen as targets. An attentional inhibition account for this distractor-devaluation effect posits that associative links between attentional inhibition and to-be-ignored stimuli are established during search, stored, and then later reinstantiated, implying that distractor devaluation may require visual working memory (WM) resources. To assess this, we measured distractor devaluation with and without a concurrent visual WM load. Participants viewed a memory array, performed a simple search task, evaluated one of the search items (or a novel item), and then viewed a memory test array. Although distractor devaluation was observed with low (and no) WM load, it was absent when WM load was increased. This result supports the notions that active association of current attentional states with stimuli requires WM and that memory for these associations plays a role in affective response.     

The study of socioethical issues in systems biology

Systems biology is the rapidly growing and heavily funded successor science to genomics. Its mission is to integrate extensive bodies of molecular data into a detailed mathematical understanding of all life processes, with an ultimate view to their prediction and control. Despite its high profile and widespread practice, there has so far been almost no bioethical attention paid to systems biology and its potential social consequences. We outline some of systems biology's most important socioethical issues by contrasting the concept of systems as dynamic processes against the common static interpretation of genomes. New issues arise around systems biology's capacities for in silico testing, changing cultural understandings of life, synthetic biology, and commercialization. We advocate an interdisciplinary and interactive approach that integrates social and philosophical analysis and engages closely with the science. Overall, we argue that systems biology socioethics could stimulate new ways of thinking about socioethical studies of life sciences.     

Sectioned offenders presenting with enduring mental illness: a study exploring behaviors indicative of bullying

Logit and logistic regression analyses were employed to explore the nature, extent and predictors of behaviors indicative of "being bullied" and of "bullying others" in a sample of 125 adult male offender-patients sectioned for enduring mental illness and detained within a high-secure psychiatric hospital. The study addresses the lack of research into this specialized population to date, with a subsidiary aim of comparing the results directly with a previous study conducted with a population of adult male personality-disordered offender-patients (n = 53). Participants were required to complete a self-report behavioral checklist (Direct and Indirect Patient behavior Checklist-Hospital version Revised). The prediction that indirect (subtle) aggression would be reported more frequently than direct aggression was supported in relation to perpetration estimates, with evidence such aggression was also more prevalent among personality-disordered than mentally ill offender-patients. As predicted verbal aggression was the most commonly reported direct behavior. Although it was predicted that those perpetrating aggression would present with increased experience with secure settings this was only supported with regard to bully-victims. Contrary to the prediction made, those victimized did not present with less experience of secure settings. Consistent with the hypothesis, bully/victims were predicted by increased negative behavior toward staff and hospital rules. The results are discussed in relation to the environment in which the aggression is taking place with the implications for practice and future research outlined.     

One-shot illusory correlations and stereotype formation

In four studies, the authors explored the emergence of one-shot illusory correlations--in which a single instance of unusual behavior by a member of a rare group is sufficient to create an association between group and behavior. In Studies 1, 2, and 3, unusual behaviors committed by members of rare groups were processed differently than other types of behaviors. They received more processing time, prompted more attributional thinking, and were more memorable. In Study 4, the authors obtained evidence from two implicit measures of association that one-shot illusory correlations are generalized to other members of a rare group. The authors contend that one-shot illusory correlations arise because unusual pairings of behaviors and groups uniquely prompt people to entertain group membership as an explanation of the unusual behavior.
