Longitudinal associations between low morning cortisol in infancy and anger dysregulation in early childhood in a CPS‐referred sample 下载免费PDF全文
Allison Frost Caitlin Jelinek Kristin Bernard Teresa Lind Mary Dozier 《Developmental science》2018,21(3)
Children who experience early adversity are at increased risk for developing psychopathology, and dysfunction of the hypothalamic pituitary adrenal (HPA) axis is a possible mechanism conferring this risk. This study sought to characterize the association between morning cortisol during different developmental periods and deficits in children's emotion regulation, a core feature of many psychological disorders. Morning cortisol was collected at two time points (i.e., during infancy, M = 13.0 months old, and during early childhood, M = 36.8 months old) from 120 children with histories of child protective services (CPS) involvement. Children completed a lab visit during early childhood (M = 38.6 months old) that involved an observational measure of anger regulation. Results showed that low morning cortisol during infancy, but not early childhood, predicted increased anger dysregulation during early childhood. These results highlight the importance of developmental timing in assessing the effects of HPA axis functioning and suggest that low cortisol during infancy is a risk factor for later emotion regulation difficulties. 相似文献

Turner syndrome (TS) is a genetic disorder, affecting 1/2500 to 1/3000 live female births, induced by partial or total deletion of one X chromosome. The neurocognitive profile of girls with TS is characterized by a normal Verbal IQ and weaknesses in visual-spatial, mathematics, and social cognitive domains. Executive functions (EFs) impairments have also been reported in these young patients. However, methodological differences across studies do not allow determination of which EFs are impaired and what is the magnitude of these impairments. The aim of this review was to clarify the EF profile of children and adolescents with TS. Sixteen samples, from thirteen studies, were included in the current meta-analysis. EFs measures used in these studies were classified into working memory, inhibitory control, cognitive flexibility, or higher-order EFs tasks in accordance with Diamond’s model, Annual Review of Psychology, 64, 135–168 (2013). Results confirmed that girls with TS had significant executive impairments with effect sizes varying from small (inhibitory control) to medium (cognitive flexibility) and large (working memory, higher-order EFs). Analyses by task revealed that cognitive inhibition may be more impaired than the other inhibitory control abilities. Heterogeneity across cognitive flexibility measures was also highlighted. Between-sample heterogeneity was observed for three tasks and the impact of participants’ characteristics on EFs was discussed. This meta-analysis confirms the necessity to assess, in patients living with TS, each EF by combining both visual and verbal tasks. Results also underline that, when studying girls with TS’ executive profile, it is important to explore the impact of moderator variables, such as IQ, parental socio-economic status, TS karyotype, psychiatric comorbidities, and hormonal treatment status. 相似文献

Brief Counseling for Alcohol Misuse Among Trauma Patients: Two Interventions and Influence of Baseline Use 下载免费PDF全文
Jennifer L. Rogers Janine M. Bernard Laura J. Veach Regina R. Moro Nathaniel N. Ivers Beth A. Reboussin Preston Miller Mary Claire O'Brien 《Journal of Addictions & Offender Counseling》2018,39(2):89-105
This study examined whether baseline trauma patient characteristics and randomized participation in 1 of 2 brief interventions predicted changes in alcohol use at 6 months postintervention. Higher total Alcohol Use Disorders Identification Test (AUDIT) scores predicted greater changes, and specific AUDIT items were significant predictors. 相似文献

This empirical article presents the first evidence of a “safety mechanism” based on an observational-learning paradigm. It is accepted that during observational learning, a person can use different strategies to learn a motor skill, but it is unknown whether the learner is able to circumvent the encoding of an uncompleted observed skill. In this study, participants were tested in a dyadic protocol in which an observer watched a participant practicing two different motor sequences during a learning phase. During this phase, one of the two motor sequences was interrupted by a stop signal that precluded motor learning. The results of the subsequent retention test revealed that both groups learned the two motor sequences, but only the physical practice group showed worse performance for the interrupted sequence. The observers were consequently able to use a safety strategy to learn both sequences equally. Our findings are discussed in light of the implications of the action observation network for sequence learning and the cognitive mechanisms of error-based observation. 相似文献

Peer aggression and victimization are ubiquitous phenomena in schools which warrant the attention of educators and researchers. The high connection between aggression and victimization behooves researchers to look into how the comorbidity of them develops over time. The present study investigated the associations between aggression and victimization over 3 years in early adolescence and whether these associations are moderated by gender and teacher support. Participants were 567 Grade 7, 8 and 9 students (49.38% girls) from 3 schools in Hong Kong. Over the course of study, they were asked to fill in a set of questionnaires that consisted of items related to peer aggression, victimization, and teacher support at 5 time points. Four models of cross-lagged relations between peer aggression and victimization were tested. The results supported a reciprocal model of peer aggression and victimization for both boys and girls although girls engaged in less peer aggression and victimization than boys. Further analyses also revealed that teacher support acted as a suppressor of the reciprocal relations. The present study sheds lights on intervention strategies that may remediate peer aggression and victimization in schools. 相似文献
