Cannabinoid receptors activation and glucocorticoid receptors deactivation in the amygdala prevent the stress-induced enhancement of a negative learning experience

The enhancement of emotional memory is clearly important as emotional stimuli are generally more significant than neutral stimuli for surviving and reproduction purposes. Yet, the enhancement of a negative emotional memory following exposure to stress may result in dysfunctional or intrusive memory that underlies several psychiatric disorders. Here we examined the effects of stress exposure on a negative emotional learning experience as measured by a decrease in the magnitude of the expected quantity of reinforcements in an alley maze. In contrast to other fear-related negative experiences, reward reduction is more associated with frustration and is assessed by measuring the latency to run the length of the alley to consume the reduced quantity of reward. We also examined whether the cannabinoid receptors agonist WIN55,212-2 (5 μg/side) and the glucocorticoid receptors (GRs) antagonist RU-486 (10 ng/side) administered into the rat basolateral amygdala (BLA) could prevent the stress-induced enhancement. We found that intra-BLA RU-486 or WIN55,212 before stress exposure prevented the stress-induced enhancement of memory consolidation for reduction in reward magnitude. These findings suggest that cannabinoid receptors and GRs in the BLA are important modulators of stress-induced enhancement of emotional memory.     

The role of centrality to self-concept in moderating the associations between injury perceptions and outcomes

Abstract

Objectives: To test the centrality of injury to self-concept as a moderator of the associations between injury perceptions and outcomes.

Methods: Two concurrent studies on samples of injured individuals.

Measures: The centrality of injury to one’s self concept was measured by the degree of self-injury separation (PRISM); injury perceptions were measured by the injury perception questionnaire; and outcomes by standard scales of self-assessed health, physical, emotional and social functioning, vitality, depression, anxiety and somatisation. Regression analyses examined the significance of adding the interactions between injury centrality and injury perceptions to explained outcome variance, beyond their separate contributions.

Results: Both injury centrality and injury perceptions significantly explained variance in patients’ functioning and well-being. Injury centrality moderated the associations between various injury perceptions and outcomes, especially pronounced for emotional representations of the injury. As hypothesised, the effects of injury perceptions on outcomes were stronger among patients for whom the injury was central to their self-concept compared to patients who perceived the injury as peripheral to their self-concept.

Conclusions: ‘Centrality to the self’ is a moderator of the impact of perceptions on outcomes of injuries. The findings suggest ways to tailor interventions to sub-groups of injured patients based on injury centrality to their self-concept.     

Posttraumatic Growth, Posttraumatic Stress Symptoms and Mental Health Among Coronary Heart Disease Survivors

The present study aimed to estimate posttraumatic stress symptoms (PTSS) and posttraumatic growth (PTG) among heart disease survivors and examine whether PTG moderates the association between PTSS and mental health. Data from 82 myocardial infarction and acute coronary artery bypass graft survivors (aged 46–82) was obtained at admission to a cardiac rehabilitation unit. Mental status was assessed by the PTSD Inventory, Posttraumatic Growth Inventory (PTGI), Mental Health Inventory and Health Related Quality of Life (HRQOL). 17.1 % of the participants suffered significantly from PTSS and most of the study sample (71.2 %) reported PTG. PTSS were positively associated with PTG and psychological distress and negatively with well-being and HRQOL. PTG moderated the association between PTSS and most mental health outcomes. We conclude that posttraumatic growth may attenuate the negative effect of posttraumatic stress symptoms on mental health.     

Non‐violent resistance and violence against siblings

A parent‐training approach to the treatment of violence against siblings according to the principles of non‐violent resistance was developed aiming at resisting the violence, providing protection to the victims and reducing escalation between the parents and the violent child.     

Changes in Interviewers' Use of Supportive Techniques during the Revised Protocol Training

Summary: Although many children are reluctant to disclose abuse due to embarrassment, fear, and the anticipation of negative consequences, researchers have only recently begun to examine whether forensic interviewers can be trained to manage children's reluctance. In this study, the supportiveness of 53 experienced interviewers was assessed in their interviews with 321 3‐ to 14‐year‐old alleged victims, each conducted during the course of training to use the Revised Protocol (RP). The use of support increased, especially between levels evident at baseline and in the last two interviews assessed. Over time, instances of inadequate support and insensitivity to children's reluctance became less common. Younger children received proportionally more support, including inadequate support, than older children. The RP training did not affect the extensive use of free recall‐based questions. Findings highlight the benefits of continued supervision and training.Copyright © 2017 John Wiley & Sons, Ltd.     

Dissociative Collusion: Reconnecting Clients with Histories of Trauma in Couple Therapy

This paper introduces the concept of “dissociative collusion” as a helpful theoretical and clinical tool for understanding and working with clients with histories of trauma in couple therapy. The paper describes ways to diagnose and treat dissociative collusion based on the integration of an object relations approach, a relational approach, and a narrative approach. Dissociative collusion, a unique version of the well‐documented “couple collusion,” describes relational unconscious dynamics where split‐off aspects of one or both partners are mutually dissociated in a complementary fashion that becomes a part of the shared unconscious and is reenacted in destructive ways. The dissociative collusion concept is especially relevant to couple therapists who work with clients with histories of trauma, who frequently use dissociation as a primary defense mechanism. We suggest that the challenge and goal for couple therapy with this population are to help them reconnect and better oscillate between dissociated self‐other configurations. A case of couple therapy of a wife who had been a victim of childhood sexual abuse and her husband who displayed frequent use of dissociative defenses is presented.     

Does the type of prompt affect the accuracy of information provided by alleged victims of abuse in forensic interviews?

Forty‐three victims of sexual abuse averaging 9.78 years of age and 52 youths who admitted abusing them were interviewed about the abusive incidents. Forensically relevant details provided by the victims were categorised as confirmed, contradicted or ignored by the perpetrators. Most (66.6%) of the details were ignored, but details were more likely to be confirmed when they were elicited using invitations (open‐ended free‐recall prompts) rather than focused prompts. However, similar effects were not evident with respect to contradictions. The results support predictions that information elicited using free‐recall prompts is more likely to be accurate than information elicited using focused prompts.

Gestalt Psychology as a Missing Link in Ernst Cassirer’s Mythical Symbolic Form

The main goal of this article is to investigate the mythical symbolic form in Cassirer’s Philosophy of Symbolic Form regarding its connection with visual perception. The article argues that mythical symbolic form is rooted in Gestalt principles of perception for organizing the perceptual field, and shows that these principles shape the main features of space and time in Cassirer’s mythical symbolic form. This argument challenges Heidegger’s critique of Cassirer’s definition of a mythical symbolic form that it is directionless and not grounded in man’s being. The combination of Gestalt principles and mythical symbolic forms supports the argument about the active role of visual perception, and clarifies Cassirer’s application and re-definition of Kantian and Neo-Kantian concepts. The investigation opens a perspective for comprehending the mythic-religious phenomenon as well as for comprehending visual perception.     

Caring,Gender Role Orientation,and Volunteering

The current studies were conducted to examine two questions regarding the development of an ethic of care versus an ethic of justice, where the former is associated with being female and the latter is associated with being male. First, does gender role orientation in adolescence predict the ethical orientation one adopts better than gender itself does? Second, does adolescents' ethical orientation predict their volunteering behavior? To answer these questions, two studies were conducted. In Study 1, adolescents completed Bem's Sex Role Inventory (BSRI) and Jensen's World View Questionnaire (WVQ) which assesses ethical orientation. Girls and individuals high in femininity were higher on the ethic of care than were boys and individuals high in masculinity. In addition, individuals with a feminine gender orientation received higher care scores than individuals with an androgynous orientation. Regression analyses indicated that gender orientation accounted for more of the variance in the ethic of care than did gender. In Study 2, older adolescents completed Jensen's WVQ and were subsequently asked to volunteer in one of two settings: a personal setting or an impersonal setting. Individuals high in the ethic of care were more likely to volunteer and volunteered for more hours, but volunteered equally often in the two types of settings. Individuals who “apologized” for being unable to volunteer were higher on caring. The results are discussed in the context of Gilligan's theory of socialization to morality.
