In three experiments we assessed the effect of an anti-emetic, the selective S-HT antagonist ondansetron, on (1) the conditioning of a taste aversion using lithium chloride (LiCl); (2) the expression of that aversion; and (3) instrumental outcome-devaluation effects. In Experiment 1 it was found that ondansetron reduced the aversion induced by LiCl when administered prior to the LiCl injection and also attenuated the expression of that aversion when administered prior to test sessions. In Experiments 2 and 3, thirsty rats were trained, in a single session, to lever press and chain pull for sucrose and saline solutions concurrently before being injected with LiCl. They were then re-exposed to both solutions, one after injection of vehicle and the other after injection of ondansetron. In a choice extinction test on the levers and chains, animals performed more of the action whose training outcome was re-exposed under ondansetron than the other action, whether the test was conducted after an injection of vehicle or after one of ondansetron. 相似文献

Is Cumulative Exposure to Suicide Attempts and Deaths a Risk Factor for Suicidal Behavior Among Firefighters? A Preliminary Study 下载免费PDF全文
Nathan A. Kimbrel PhD Michelle L. Pennington BA Claire M. Cammarata PhD Frank Leto BA William J. Ostiguy Suzy B. Gulliver PhD 《Suicide & life-threatening behavior》2016,46(6):669-677
The association between cumulative exposure to suicide attempts and deaths and suicidal behavior was examined in a sample of 61 professional firefighters. On average, firefighters reported 13.1 (SD = 16.6) exposures over the course of their lifetime. Cumulative exposure to suicide attempts and deaths was positively correlated with suicidal behavior (r = .38, p = .004). Moreover, firefighters with 12+ exposures were more likely to screen positive for risk of suicidal behavior (OR = 7.885, p = .02). Additional research on the potential impact of cumulative exposure to suicide attempts and deaths on firefighters' health and safety is needed. 相似文献

Cool and hot executive function as predictors of aggression in early childhood: Differentiating between the function and form of aggression 下载免费PDF全文
Sarah E. Poland Claire P. Monks Stella Tsermentseli 《The British journal of developmental psychology》2016,34(2):181-197
Executive function (EF) has been implicated in childhood aggression. Understanding of the role of EF in aggression has been hindered, however, by the lack of research taking into account the function and form of aggression and the almost exclusive focus on cool EF. This study examined the role of cool and hot EF in teacher reported aggression, differentiating between reactive and proactive as well as physical and relational aggression. Children (N = 106) completed laboratory tasks measuring cool (inhibition, planning, working memory) and hot EF (affective decision‐making, delay of gratification). Cool, but not hot, EF significantly contributed to understanding of childhood aggression. Inhibition was a central predictor of childhood aggression. Planning and working memory, in contrast, were significant independent predictors of proactive relational aggression only. Added to this, prosocial behaviour moderated the relationship between working memory and reactive relational aggression. This study therefore suggests that cool EF, particularly inhibition, is associated with childhood aggression across the different functions and forms. 相似文献

Prenatal depressive symptoms have been linked to negative outcomes for mothers and children. Using attachment theory as a framework, this study examined developmental differences in the interpersonal context of prenatal depressive symptoms among adolescents (age 14 to 19 years; n = 352) and young adults (age 20 to 24 years; n = 348). Participants included low-income, single, predominantly African American and Latina women. Moderating and mediating factors were found in the relation between caregiving history (perceived unavailability and inconsistency of maternal and paternal figures during childhood) and depressive symptoms. For pregnant adolescents, maternal unavailability predicted depressive symptoms whereas maternal inconsistency did not. In contrast, for pregnant young women, only maternal inconsistency predicted depressive symptoms; and this association was mediated by perceptions of prenatal support. For both groups, paternal caregiving history had a small yet independent association with depressive symptoms. Results highlight the need to consider developmental differences in the interpersonal context of prenatal depressive symptoms in delivering mental health interventions to young women of color. 相似文献

Although counselors in 44 states are mandatory reporters of child maltreatment, they may lack an understanding of their legally designated role. This article presents the results of a systematic review of child maltreatment reporting laws in all 50 states and the District of Columbia. The authors apply relevant legislation to real‐life contexts for counselors. 相似文献

This review of 20 years of developmental research on Executive Functions (EF) offers a broad‐brushstroke picture that touches on multiple issues including: (i) findings from typical and atypical groups, from infancy to adolescence; (ii) advances in assessment tools and in statistical analysis; (iii) the interplay between EF and other cognitive systems (e.g. those involved in children's developing understanding of mind, and in their processing of reward signals); (iv) integration of cognitive and neuroscience perspectives on EF; and (v) environmental factors that have either a positive influence (e.g. training/intervention programmes; parental scaffolding) or a negative influence (e.g. maltreatment, neglect, traumatic brain injury) on EF. Of the several themes to emerge from this review, two are particularly important; these concern the need to adopt developmental perspectives and the potential importance for intervention work of research on social influences on EF. Specifically, the review highlights both developmental continuities (e.g. in the correlates of EF) and contrasts (e.g. in the nature of EF and its neural substrates) and calls for research that compares developmental trajectories for EF in different groups (e.g. children with autism versus ADHD). In addition, findings from both family‐based research and randomized controlled trials of school‐based interventions highlight the importance of environmental influences on EF and so support the development of interventions to promote EF and hence improve children's academic and social outcomes.

Questionnaires concerning reasons for enrolling one's child in nursery school were completed by 599 parents in a Midwestern city. Parents of girls and boys did not differ in mean ratings of reasons. However, a greater number of reasons were rated as more important by boys' parents than by girls' parents for both lower- and middle-class respondents. Proportionately more lower-class boys than lower-class girls were enrolled in the city's nursery schools. These data are consistent with the hypothesis that lower-class parents consider preschool education to be more important for boys than girls. 相似文献
