The purpose of the study was to investigate a possible association between brain activation in functional magnetic resonance imaging scans, cognition and school performance in extremely preterm children and term born controls. Twenty eight preterm and 28 term born children were scanned while performing a working memory/selective attention task, and school results from national standardized tests were collected. Brain activation maps reflected difference in cognitive skills but not in school performance. Differences in brain activation were found between children born preterm and at term, and between high and low performers in cognitive tests. However, the differences were located in different brain areas. The implication may be that lack of cognitive skills does not alone explain low performance due to prematurity.  相似文献

Boys’ use of muscle building techniques during early adolescence is poorly understood. The present study investigated the impact of gender role intensification, investment in muscular media images, appearance social comparison, and attitudes concerning muscularity on the use of muscle building techniques. Middle school boys (N?=?143; M age?=?12.92 years) from the Midwestern United States completed questionnaires. They were re-assessed 7 months later. Structural equation modeling indicated that gender role intensification as well as Time 1 media investment, and social comparison predicted Time 2 media investment in the muscular ideal which was in turn correlated with Time 2 muscle building. Implications for prevention of body image problems and muscle building among boys are discussed.  相似文献

We argue for community psychology to include digital communications technology in research on ways that the social environment shapes fundamental human experiences. We present a qualitative study that examined the narrative accounts of 20 young adults who experienced the death of a close friend to describe both traditional and digital forms of remembrance in coping with loss. Findings suggest that young adults' activities both online and offline were intended to acknowledge the loss, exchange social support, create and sustain memories of their deceased friend, and facilitate continued communication with the deceased. Participants described both costs and benefits to their real and virtual remembrance activities. Findings illustrate ways that the study of digital technology adds to our understanding of grief and bereavement and contributes to dominant cultural narratives about coping with death. Implications of findings for research in community psychology are discussed.  相似文献

Numerous studies have demonstrated the efficacy of cognitive processing therapy (CPT) for treating posttraumatic stress disorder (PTSD). Two prior meta-analyses of studies are available but used approaches that limit conclusions that can be drawn regarding the impact of CPT on PTSD outcomes. The current meta-analysis reviewed outcomes of trials that tested the efficacy of CPT for PTSD in adults and evaluated potential moderators of outcomes. All published trials comparing CPT against an inactive control condition (i.e. psychological placebo or wait-list) or other active treatment for PTSD in adults were included, resulting in 11 studies with a total of 1130 participants. CPT outperformed inactive control conditions on PTSD outcome measures at posttreatment (mean Hedges’ g = 1.24) and follow-up (mean Hedges’ g = 0.90). The average CPT-treated participant fared better than 89% of those in inactive control conditions at posttreatment and 82% at follow-up. Results also showed that CPT outperformed inactive control conditions on non-PTSD outcome measures at posttreatment and follow-up and that CPT outperformed other active treatments at posttreatment but not at follow-up. Effect sizes of CPT on PTSD symptoms were not significantly moderated by participant age, number of treatment sessions, total sample size, length of follow-up, or group versus individual treatment; but, older studies had larger effect sizes and percent female sex moderated the effect of CPT on non-PTSD outcomes. These meta-analytic findings indicate that CPT is an effective PTSD treatment with lasting benefits across a range of outcomes.  相似文献
