Using cluster analyses, this study explored the relations among racial identity, perceived discrimination, and psychological concerns among 189 Caribbean Black American and African American adolescents. Findings showed that for all participants, less mature racial identity profiles were significantly related to perceived discrimination and psychological concerns. However, nuances in racial identity profiles between Caribbean Black American and African American participants suggest subtle ethnic group differences in racial identity development. Implications for practitioners and research are discussed. Usando análisis cluster, este estudio exploró las relaciones entre identidad racial, discriminación percibida y preocupaciones psicológicas en 189 adolescentes afroamericanos y americanos negros caribeños. Los hallazgos mostraron que, para todos los participantes, los perfiles de identidad racial menos maduros estaban significativamente relacionados con una discriminación percibida y preocupaciones psicológicas. Sin embargo, los matices de los perfiles de identidad racial entre los participantes afroamericanos y americanos negros caribeños sugieren unas diferencias sutiles entre ambos grupos étnicos en el desarrollo de la identidad racial. Se discuten las implicaciones para practicantes e investigadores.  相似文献

The effects of context reinstatement as means of enhancing 5‐ and 6‐year‐old children's event memory in repeated interviews after a 6‐month delay were examined. Children were interviewed immediately after the event (baseline interview) and twice at a 6‐month delay, with 24 hours between interviews. The first 6‐month interview was conducted in a perfect‐context reinstatement (n = 15), imperfect‐context reinstatement (n = 16), or no‐context reinstatement (n = 15) condition. The second 6‐month interview was conducted 24 hours later with no‐context reinstatement for all children. Context reinstatement attenuated the effects of delay on recall. The accuracy of the details reported was greater in the perfect‐context compared to the imperfect‐context and no‐context conditions. Details repeated between the immediate‐baseline interview and in the first 6‐month interview were more accurate than details repeated between the first and second 6‐month interview. There was no increase in recall (hypermnesia) across the first and second 6‐month interviews in any condition. Practical implications of these findings are discussed.

Evidence from theory-of-mind tasks suggests that young children have substantial difficulty thinking about multiple object identity and multiple versions of reality. On the other hand, evidence from children's understanding of pretense indicates that children have little trouble understanding dual object identity and counterfactual scenarios that are involved in pretend play. Two studies reported here show that this competence is not limited to pretend play. Three-year-olds also understand the dual identity involved in unusual functional use (X is being used as Y), even though they have difficulty understanding deceptive appearance (X looks like Y). We suggest that children are able to distinguish extrinsic object properties from intrinsic ones (function vs. category-membership) better than they can distinguish superficial object properties from deep ones (appearance vs. category-membership).  相似文献

The purpose of the present study was to better understand the development of children's occupational knowledge, as assessed by their ability to give ratings to jobs along various dimensions that were similar to ratings given by adults, and to investigate differences in boys' and girls' ratings. Overall, younger students gave higher ratings to the jobs pictured than did older students. Also, females gave higher ratings to three of the four dimensions investigated. Girls rated traditionally female jobs higher on respect and service, while boys rated traditionally male jobs higher on respect and service. Both males and females agreed that more education would be required for the female jobs pictured, but that males would be paid more money for the male jobs pictured.  相似文献

The results of a functional analysis showed that inappropriate sexual behaviors exhibited by a 9-year-old boy who had been diagnosed with traumatic brain injury were maintained by positive reinforcement in the form of social attention. An intervention consisting of functional communication training and extinction resulted in reduced levels of inappropriate sexual behaviors.  相似文献

Childhood externalizing disorders have been linked to adult affective disorders, although some studies fail to substantiate this finding. Multiple longitudinal cohort studies identifying childhood psychopathology and their association with adult psychiatric illness have been published. To examine the association between childhood externalizing symptoms or disorders and the development of adult depression across cohorts, a meta-analysis was performed. Potential studies were identified using a PubMed search through November 2013. All published, prospective, longitudinal, community-sampled cohort studies of children (≤ 13 years) with externalizing symptoms or disorders (aggression, conduct problems, oppositional defiant disorder, conduct disorder), reassessed in adulthood (≥ 18 years) for depressive disorders (major depressive disorder, depressive disorder NOS, or dysthymic disorder) were included. A random effects model was used to summarize the pooled effect sizes. Ancillary analyses considered covariates that could account for variance among studies. Ten studies representing eight cohorts of children initially assessed at age 13 or younger (N?=?17,712) were included in the meta-analysis. Childhood externalizing behavior was associated with adult depressive disorders (OR?=?1.52, 95 % confidence interval?=?1.27–1.80, p?相似文献

Since the September 11th attacks on the U.S., more than 2 million children have experienced parental deployment during their early years, with potentially lasting impact. When a parent is deployed, a number of factors may affect the well-being of the service member and his/her family. One parental factor—posttraumatic stress disorder or distress—might be particularly powerful in its effect on young children and the family system. We analyzed baseline data from an intervention development project which focused on supporting military families with very young children during post-deployment. The purpose of this research is to understand the relationships between parental mental health status, parenting stress, couple functioning, and young child well-being. The effects of mental health status of home-front and service member parents and the role of couple functioning on parent–child interactions and behavioral problems of young children were examined in a sample of military families during the post-deployment period. Findings suggest that service member posttraumatic stress symptoms are associated with higher parental report of child behavior problems. Higher quality of the couple relationship appears to lessen the impact of parental posttraumatic stress but is not related to parent perceptions of child behavior concerns. Implications for future research with military families are discussed.  相似文献
