Disequilibrium in the mind,disharmony in the body

Although it is generally acknowledged that experiences of frustration, confusion, and anxiety are embodied phenomena, very little is known about how these processes modulate presumably unconscious, but constantly present, subtle bodily movement. We addressed this problem by tracking the low-level dynamics of body movement, using 1/f noise, pink noise, or “fractal scaling”, during naturalistic experiences of affect in two studies involving deep learning and effortful problem-solving. Our results indicate that body movement fluctuations of individuals experiencing cognitive equilibrium was characteristic of correlated pink noise, but there was a whitening of the signal when participants experienced states that are diagnostic of cognitive distress such as anxiety, confusion, and frustration. We orient our findings within theories that emphasise the embodied nature of cognition and affect and with perspectives that view affective and cognitive processes as emergent products of a self-organising dynamical system (the brain) that is inextricably coupled to the body.     

Autobiographical memory specificity and the persistence of depressive symptoms in HIV-positive patients: Rumination and social problem-solving skills as mediators

Individuals infected with human immunodeficiency virus (HIV) are at elevated risk for depressive conditions, which in turn can negatively impact health-related behaviours and the course of illness. The present study tested the role of autobiographical memory specificity and its interaction with perceived stress in the persistence of depressive symptoms among dysphoric HIV-positive individuals. Additionally, we examined whether rumination and social problem solving mediated these effects. Results indicated that memory specificity moderated the impact of perceived stress, such that perceived stress was more strongly associated with follow-up depressive symptoms among those with greater memory specificity. Rumination, but not social problem solving, mediated this effect. Implications of these findings are discussed.     

Transitioning from the Battlefield to Home: An Innovative Program for Israeli Soldiers

Soldiers moving from the army to civilian life encounter significant challenges during this time of transition, both in Israel and internationally. Identifying this period of time as a critical one, the Peace of Mind program is an innovative intervention designed specifically to address the issues occurring therein. This unique model focuses on mental health and normalization of responses, as well as on the processing of traumatic experiences. It is based on the considerable experience at the Israel Center for the Treatment of Psychotrauma in the fields of resilience building and trauma treatment. After reviewing the literature on returning soldiers, the model is described and several vignettes are presented.     

Examining the Relationships Between the Justice Facets and Turnover Intent: The Mediating Roles of Overall Justice and Psychological Strain

We examined how interpersonal justice from coworkers, the traditional justice facets (i.e., distributive, procedural, interpersonal, informational), and overall justice perceptions relate to employee psychological strain and turnover intentions in Canadian Armed Forces personnel. Specifically, we hypothesized that overall justice would mediate the relationships between the justice facets (including coworker justice) and strain, and strain would mediate the relationship between overall justice and turnover intent. We used a cross-sectional correlational design with personnel from 2 military units (total N = 218) as our sample. A 2-step structural equation modeling technique was used to evaluate our hypotheses. Support for our hypotheses was obtained with 1 exception: informational justice did not predict overall justice judgments. Our results suggest that employees’ reactions to individual justice events and different sources of justice exert their effects on strain and turnover intent indirectly through their impact on a global evaluation of justice in their work environment.     

EDITORIAL

The aim of the present study was to evaluate the usefulness of Barkley’s (1997a) model of inhibition and executive functioning in describing the deficits associated with Attention Deficit Hyperactivity Disorder (ADHD). Besides group differences, the present study addressed the question of independent effects of inhibition and the other executive functions in discriminating between children with ADHD and controls and how well, in terms of sensitivity and specificity, these measures can classify the children into the correct group. The results showed that children with ADHD differed significantly from controls with regard to measures of inhibition as well as all other executive function measures, except repetition of hand movements. In logistic regression models, three different measures tapping inhibition, working memory and emotion regulation were shown to be significant independent predictors of group membership. The sensitivity for these three variables as a set was 76.2, the specificity was 90.5, with a total of 86% of the sample correctly classified. When excluding the parental rating of emotion regulation, the overall classification rate decreased some, but was still relatively high in comparison with previous studies within this area of research.     

Elementary school students with AD/HD: predictors of academic achievement

Academic underachievement frequently is associated with attention-deficit/hyperactivity disorder (AD/HD); however, the role of variables beyond AD/HD symptoms and cognitive mediators is unknown. Further, whether prediction models vary (a) relative to non-AD/HD students, (b) between math and reading, and (c) based on how achievement is defined has not been examined. Multiple measures (e.g., teacher ratings and behavior observations) were examined as predictors for concurrent achievement outcomes (standardized achievement test scores and report card grades) in math and reading in two samples of 1st through 4th grade children (136 with AD/HD, 53 without AD/HD). Teacher perceptions of academic skills were the strongest predictors of achievement test scores for both groups, while academic skills and enablers accounted for reading report card grades in children with AD/HD but not their normal counterparts. Implications of these findings for school-based assessment and intervention for students with AD/HD are discussed.     

初中生偶像崇拜及其与生活目标和主观幸福感的关系:性别的调节作用

本研究以3587名初中生为对象,采用问卷测量法,考察了初中生偶像崇拜在性别和年级上的差异,及其与生活目标和主观幸福感的关系,并探究了性别在其中的调节作用。研究发现：（1）女生的偶像崇拜水平显著高于男生的,且偶像崇拜高水平组中女生人数显著多于男生,偶像崇拜低水平组中则相反;初一与初二年级间偶像崇拜的水平及在不同水平上的人数分布均无显著差异。（2）外在生活目标能够正向预测初中生的偶像崇拜水平,其中性别起调节作用,外在生活目标对女生偶像崇拜水平的影响大于男生。（3）性别对偶像崇拜影响初中生主观幸福感上也具有调节作用,即偶像崇拜水平负向预测初中女生的主观幸福感,对男生的主观幸福感则影响不显著。     

An examination of the roles of trauma exposure and posttraumatic stress disorder on emotion regulation strategies of Operation Iraqi Freedom,Operation Enduring Freedom,and Operation New Dawn veterans

Theories of posttraumatic stress disorder (PTSD) implicate emotional processes, including difficulties utilizing adaptive emotion regulation strategies, as critical to the etiology and maintenance of PTSD. Operation Iraqi Freedom, Operation Enduring Freedom, and Operation New Dawn (OIF/OEF/OND) veterans report high levels of combat exposure and PTSD. We aimed to extend findings suggesting that emotion regulation difficulties are a function of PTSD, rather than combat trauma exposure or common comorbidities, to OIF/OEF/OND veterans, in order to inform models of PTSD risk and recovery that can be applied to returning veterans. We tested differences in emotion regulation, measured with the Difficulties in Emotion Regulation Scale and Emotion Regulation Questionnaire, among trauma-exposed veterans with (n = 24) or without PTSD (n = 22) and healthy civilian comparison participants (n = 27) using multivariate analyses of covariance, adjusting for major depressive disorder, anxiety disorders, and demographic variables (age, sex, and ethnicity). Veterans with PTSD reported more use of expressive suppression and more difficulties with emotion regulation than veterans without PTSD and healthy comparison participants. Groups did not differ on cognitive reappraisal. Findings suggest the key role of PTSD above and beyond trauma exposure, depression, and anxiety in specific aspects of emotion dysregulation among OIF/OEF/OND veterans. Interventions that help veterans expand and diversify their emotion regulation skills may serve as helpful adjunctive treatments for PTSD among OIF/OEF/OND veterans.
