Preliminary evidence of the impact of early childhood maltreatment and a preventive intervention on neural patterns of response inhibition in early adolescence 下载免费PDF全文

Maltreated youths in foster care often experience negative developmental and psychological outcomes, which have been linked with poor response inhibition. Recent evidence suggests that childhood maltreatment is also associated with alterations in the neural circuitry underlying response inhibition. However, a burgeoning line of research has begun to explore the mitigating effects of preventive interventions on neural functioning. The current study used event‐related functional magnetic resonance imaging to explore the impact of early childhood maltreatment and a preventive intervention on response inhibition in early adolescence. Thirty‐six demographically similar adolescents (ages 9–14 years) completed a Go/NoGo task. The sample included nonmaltreated adolescents (n = 14) and maltreated adolescents who were in foster care as preschoolers and randomly assigned to receive services as usual (n = 11) or a preventive intervention, Multidimensional Treatment Foster Care for Preschoolers (n = 11). The groups demonstrated similar behavioral performance but significantly different neural patterns. The maltreated adolescents who received services as usual demonstrated subcortical hypoactivity during successful response inhibition and subcortical hyperactivity during unsuccessful response inhibition. In contrast, the nonmaltreated adolescents and maltreated adolescents who received the intervention exhibited strikingly similar neural patterns during successful response inhibition, but the maltreated adolescents who received the intervention demonstrated prefrontal hypoactivity during unsuccessful response inhibition. These findings offer preliminary evidence that early childhood maltreatment alters the neural patterns underlying response inhibition in early adolescence and that participating in a preventive intervention could mitigate maltreatment‐related effects on these neural systems. 相似文献

Countries have adopted different laws, policies, and practices that allow immigration officers to request in certain cases DNA tests to confirm biological relationships in the context of family reunification. In Canada, Citizenship and Immigration Canada has adopted a policy of suggesting DNA testing only as a last resort in cases where no documentary evidence has been submitted or where the evidence provided is deemed unsatisfactory. However, in practice, there have been concerns on the increasing use of DNA tests in family reunification processes of nationals from certain regions including Africa, Asia, and Latin America. Moreover, the Immigration and Refugee Protection Regulations (IRPR) presents a biological definition of family as a determinant of parenthood in the context of family reunification that is inconsistent with the psychosocial definition used in provincial family laws. Although there are cases that can justify the request for DNA tests, there are also significant social, legal, and ethical issues, including discrimination and unfair practices, raised by this increasing use of genetic information in immigration. This policy brief identifies points to consider for policymakers regarding the use of DNA testing in Canadian family reunification procedures. These include (1) the need to refine the policy of “using DNA testing as a last resort” and its implementation, (2) the need to modify the definition of “dependent child” under the IRPR to reflect the intrinsic reality of psychosocial family ties, and (3) the importance of conducting more research on the use of DNA testing in other immigration contexts. 相似文献

The moderating effect of parental warmth on the association between spanking and child aggression: a longitudinal approach 总被引:1,自引:0,他引:1
Ann Michele Stacks Toko Oshio Jean Gerard Jacqueline Roe 《Infant and child development》2009,18(2):178-194
Using data from the Early Head Start Research and Evaluation Study, this study analysed the stability of child aggressive behaviour beginning in infancy and tested whether spanking when the child was 36 months was associated with aggressive child behaviour among three ethnic groups and whether maternal warmth moderated the effect of spanking on aggressive behaviour in each ethnic group at 36 months, after controlling for earlier aggressive behaviour. Participants included 693 Hispanic parent–child dyads, 1013 African‐American dyads and 1086 Caucasian dyads who met qualifications for participation in the Early Head Start programme. Findings suggest that infant temperament was associated with aggressive behaviour at 24 and 36 months and that child aggression remained stable. Among the three ethnic groups, spanking was only associated with aggressive behaviour for children who had Caucasian mothers and maternal warmth did not moderate the effect of spanking on aggressive behaviour.

This study considers the relationship between perfectionism and perceptions of work–family conflict. A situational component to perfectionism was found, with higher standards and a higher perceived discrepancy between standards and performance at home versus at work. Findings suggest perfectionism predicts work–family conflict, beyond the effects of the Big Five, trait affectivity and achievement. Further, findings indicate those with adaptive perfectionism (AP; work and home) tend to have lower strain and time‐based family interfering with work and lower behaviour‐based work interfering with family, compared with maladaptive perfectionists (home) and non‐perfectionists (work and home). Gender differences were found and considered in a more exploratory manner. 相似文献

The current study examined the potential mediating role of sensation seeking in the well-established negative relationship between age and financial risk-taking. A total of 299 participants, aged 17–90 years, allocated hypothetical money into mutual funds that varied in risk and completed a sensation seeking measure. Hierarchical multiple regressions revealed that the amount of variability age accounted for in risk-taking (4.1%; β = −.22) was significantly reduced when sensation seeking was controlled for (0.8%; β = −.12). A Sobel test revealed that sensation seeking fully mediated the aforementioned relationship. Results suggest sensation seeking’s role as a mediator in more physiologically arousing risk-taking contexts (e.g., surfing). Discussion recommends investigating potential biologically and cognitively-rooted mediators and moderators of the age and risk-taking relationship. 相似文献

Using data from the first three waves (Grades 5, 6, and 7) of the 4-H Study of Positive Youth Development, this study assessed if being a bully or being a victim accounts for an adolescent's academic competence, if selected contextual and individual variables impact an adolescent's academic competence, and if such impact differs in relation to an adolescent's bullying status. The results of random coefficient hierarchical regression analyses indicated that being a bully predicted lower grades across time, and that being a bully was more detrimental for girls than for boys. Being a bully and being a victim negatively predicted self-perceived academic competence, but these predictive effects did not change over time or differ by sex. Teacher support positively predicted grades and greater parent support and teacher support independently predicted higher self-perceive academic competence. Greater educational expectations and school engagement independently predicted higher self-reported grades, while these two predictors positively interacted in explaining self-perceived academic competence. Unexpectedly, peer support negatively predicted self-reported grades for victims, and negatively predicted self-perceived academic competence for bullies. We discuss the importance of addressing the issue of academic competence in bullying interventions, as well as the utility of capitalizing on developmental assets in promoting academic competence among adolescents who bully and who are bullied. 相似文献

How to get “kissably close”: Examining how advertisers appeal to consumers’ sexual needs and desires 总被引:1,自引:0,他引:1
This paper explores the nature of sexual appelas—sex-related promises or benefits—in mainstream advertising by describing
types of sex appeals and findings from a sex-benefit content analysis. Overall, our findings reveal that sex is used to appeal
to women and men, although a higher proportion of sexual ads appear in men’s (12%) compared to women’s magazines (6%). In
addition, a variety of sex appeals are directed toward women (attractiveness, behavior, esteem), whereas most appeals directed
toward men emphasize more and better sex. Last, male-only images are relatively absent in sexual ads compared to female-only
(45%) and couples (47%) images. These findings, observations, and directions for future research are discussed. 相似文献

In three studies the authors investigated the development of beliefs about dreaming. Study 1 assessed 3- to 5-year-old children's beliefs about the origins and controllability of dreams. Results revealed significant changes in children's beliefs about the roles of behavioral experiences and mental processes in the generation of dream content. Results also revealed that young children consider both dreams and imagination to be highly controllable. In Study 2, preschool-age children, elementary school-age children, and adults received either imagination or dream stories and were questioned about controllability. In Study 3, emotional valence of the dream content was varied. Results of Studies 2 and 3 revealed significant development in beliefs that dreams are not subject to conscious control. Beliefs in controllability were higher among females. Study 3 showed that the emotional content of a dream affects these claims. 相似文献

Using data from the British Household Panel Survey, this short-term longitudinal study examined relationships between early- and mid-adolescents' gender role attitudes and the attitudes of their parents. Between 1994 and 1997, 602 families answered questions about the roles of husbands and wives, and whether or not having a working mother is harmful to families. Results confirmed that the gender differences that have been found consistently in the literature regarding adults extend back into early adolescence. Adolescent girls' attitudes were markedly more nontraditional than all other family members. However, results only partially supported our hypotheses regarding family influence on attitudes. In particular, we found little evidence that adolescent attitudes would more closely resemble those of the same-gender parent. Analysis of individual questions supports arguments that gender roles are complex and socially determined, and that British men of both adult and adolescent generations have begun in principle to accept nontraditional roles for wives but are less willing to support any erosion of male power in the family. 相似文献

Multiple perspectives on the assessment of children's development at the school-community interface in rural areas of Zambia are discussed in the light of several empirical studies conducted between 1974 and 2005. A longitudinal trace study of a cohort of 46 young people born into a rural, Chewa community in Katete District found that girls' scores in early childhood on a battery of ecoculturally grounded cognitive tests correlated less well than they did for boys with two educational outcomes: number of grades of schooling completed, and adult literacy scores. Conversely, ratings of the children on indigenous conceptions of intelligence by adults familiar with the children in the context of their home village lives predicted the same outcomes better for girls than for boys. A separate, linked experiment compared the performance of 76 Katete school children with that of 84 school children in the capital city of Lusaka on the US standardized Draw-a-Person Test (DPT) and the Panga Munthu Test (PMT), an expanded version of one of the tests developed for the Zambian trace study. Analysis of the correlations among scores on these two tests, age, and teacher ratings suggests that aptitudes evident in the home and school domains are less well integrated for rural girls than for urban boys, and that for a low-income, rural population, the PMT taps the domain of home cognition better than school cognition, while the converse is true of the DPT. Implications for educational assessment in Zambia are discussed, and supportive documentation is cited from two ongoing programs of test development. The authors conclude that if educational testing is to support the process of enhancing educational equity across gender, family socioeconomic status, and residential location, its focus should be broadened to include other dimensions of psychological development such as multilingual and personal-social competencies. 相似文献
