This study describes the development of emotional and behavioral regulation in a regional cohort of children born extremely preterm (<28 weeks gestational age, n = 39), very preterm (<34 weeks gestational age, n = 56), and full term (n = 103). At 2 and 4 years, children born at younger gestational ages demonstrated poorer self-regulation across multiple contexts spanning observed interactions, formal cognitive testing, and parental report of child behavior at home. Among children born preterm, the 2 strongest predictors of impairments in self-regulation were the presence of moderate-to-severe cerebral white matter abnormalities on neonatal magnetic resonance and a less sensitive parenting style when children were aged 2 years. Findings support the importance of early neurological development and parenting for developing regulation in children born very preterm. 相似文献

Over the past decades research on learning has become more diverse and complex. The concern expressed by Alexander, Schallert, and Reynolds (2009/this issue) is that this diversity of theoretical perspectives has resulted in a fragmentation that is destructive to the field. Although it is important to engage in explicit discussions of how learning is construed in different traditions, Alexander et al. do not give sufficient recognition to the significant epistemological and theoretical differences between traditions; differences that make them incompatible in important respects, for instance, with respect to their units of analysis. An acceptance of incompatibilities in perspectives is not necessarily a problem. In fact, such a situation may, if the debates are grounded in a mutual acceptance of the diverse manners in which knowing and learning may be theorized, give us a richer frame of reference from which to analyze learning in its various manifestations in complex societies. 相似文献

Exposure to childhood sexual and physical abuse and subsequent educational achievement outcomes 总被引：2，自引：0，他引：2
OBJECTIVE: This paper examined the relationship between exposure to sexual and physical abuse (CSA and CPA) in childhood and later educational achievement outcomes in late adolescence and early adulthood in a birth cohort of over 1,000 children studied to age 25. METHOD: Retrospective data on CSA and CPA were gathered at ages 18 and 21 and used to form a best estimate of exposure to CSA and CPA. The relationship between CSA, CPA, and self-reported educational outcomes to 25 years was examined using logistic regression models that took into account social background, parental factors, and individual factors. RESULTS: Increasing exposure to CSA and CPA was significantly associated with failing to achieve secondary school qualifications (CSA: B=.53, SE=.13, p<.0001; CPA: B=.62, SE=.12, p<.0001), gaining a Higher School Certificate (CSA: B=-.48, SE=.13, p<.001; CPA: B=-.78, SE=.14, p<.001), attending university (CSA: B=-.29, SE=.13, p<.05; CPA: B=-.45, SE=.13, p<.001), and gaining a university degree (CSA: B=-.54, SE=.18, p<.005; CPA: B=-.64, SE=.17, p<.001). Adjustment for confounding social, parental, and individual factors explained most of these associations. After control for confounding factors, omnibus tests of the associations between CSA and outcomes and CPA and outcomes failed to reach statistical significance (CSA: Wald chi(2) (4)=7.72, p=.10; CPA: Wald chi(2) (4)=8.26, p=.08). CONCLUSIONS: The effects of exposure to CSA and CPA on later educational achievement outcomes are largely explained by the social, family, and individual context within which exposure to abuse takes place. 相似文献

Does father absence place daughters at special risk for early sexual activity and teenage pregnancy? 总被引：6，自引：0，他引：6

The impact of father absence on early sexual activity and teenage pregnancy was investigated in longitudinal studies in the United States (N = 242) and New Zealand (N = 520), in which community samples of girls were followed prospectively from early in life (5 years) to approximately age 18. Greater exposure to father absence was strongly associated with elevated risk for early sexual activity and adolescent pregnancy. This elevated risk was either not explained (in the US. study) or only partly explained (in the New Zealand study) by familial, ecological, and personal disadvantages associated with father absence. After controlling for covariates, there was stronger and more consistent evidence of effects of father absence on early sexual activity and teenage pregnancy than on other behavioral or mental health problems or academic achievement. Effects of father absence are discussed in terms of life-course adversity, evolutionary psychology, social learning, and behavior genetic models. 相似文献

Cognitive impairment is common among children born very preterm (VPT), yet little is known about how this risk changes over time. To examine this issue, a regional cohort of 110 VPT (≤ 32 weeks gestation) and 113 full‐term (FT) born children was prospectively assessed at ages 4, 6, 9, and 12 years using the Wechsler Preschool and Primary Scale of Intelligence–Revised and then Wechsler Intelligence Scale for Children, 4th ed. At all ages, VPT children obtained lower scores than their FT born peers (p < .001). Growth curve modeling revealed stable cognitive trajectories across both groups. Neonatal white matter abnormalities and family socioeconomic adversity additively predicted cognitive risk. Despite some intraindividual variability, cognitive functioning of typically developing and high‐risk VPT children was stable and influenced by early neurological development and family rearing context. 相似文献

In this paper, I draw on observations from sexual health workshops in an elementary school classroom in Vancouver, Canada and friendship pair interviews with four boys who attended the workshops. I examine how the educators organising the workshops constructed sexual health, highlighting their reliance on both a ‘gay is okay’ and a scientific discourse. I argue that by locating their discussion of homosexuality within a values framework and striving to depict gay relationships as acceptable, they simultaneously constituted homosexuality as requiring acceptance. Likewise, by subsuming references to heterosexuality within their lesson on (hetero)sexual reproduction, they framed heterosexuality as an always already accepted scientific fact. Having set the scene in this way, I then explore the ways the boys both took up and deviated from these discourses when constructing their own narratives. 相似文献

ObjectiveThe present study examined the associations between the experience of sexual abuse in childhood (CSA) and the number of abortions in adolescence and early adulthood.MethodA 25-year prospective longitudinal study of the health, development, and adjustment of a birth cohort of 1,265 New Zealand children (630 females). Measures included assessments of experience of CSA using retrospective data gathered at ages 18 and 21, self-reported abortions from ages 15 to 25, measures of childhood socio-economic disadvantage, family stability, family functioning, experience of childhood physical abuse, and pregnancy in adolescence and early adulthood.ResultsSeverity of CSA experience was significantly (p < .01) associated with an increasing rate of abortions during ages 15–25. Adjustment of the association for potentially confounding factors from childhood reduced the magnitude of the association, but it remained marginally statistically significant (p < .10). However, controlling for the mediating effects of pregnancy risk in adolescence and early adulthood reduced the association between experience of CSA and abortion to statistical non-significance (p > .70).ConclusionsThe current study suggested that the association between experience of CSA and increased rates of abortion was mediated by the increased rates of pregnancy associated with CSA experiences. The results suggest a causal chain in which experience of CSA leads to increased rates of pregnancy, which in turn leads to increased rates of abortion. 相似文献

OBJECTIVE: This research examined linkages between exposure to childhood sexual abuse (CSA) and childhood physical punishment/abuse (CPA) and mental health issues in early adulthood. METHOD: The investigation analyzed data from a birth cohort of over 1,000 New Zealand young adults studied to the age of 25. RESULTS: Exposure to CSA and CPA was associated with increased risks of later mental disorders including depression, anxiety disorder, conduct/anti-social personality disorder, substance dependence, suicidal ideation, and suicide attempts at ages 16-25. Control for social, family, and individual factors reduced the associations between CPA and mental health outcomes to the point of statistical non-significance. However, there was a consistent finding for CSA to remain associated with increased risks of later mental health problems. After adjustment, those exposed to CSA including attempted or completed sexual penetration had rates of disorder that were 2.4 times higher than those not exposed to CSA. Those exposed to harsh or abusive physical punishment had rates of disorder that were 1.5 times higher than those exposed to no or occasional physical punishment. It was estimated that exposure to CSA accounted for approximately 13% of the mental health problems experienced by the cohort. Findings showed that exposure to CPA had only weak effects on later mental health. It was estimated that exposure to CPA accounted for approximately 5% of the mental health problems experienced by the cohort. CONCLUSIONS: Exposure to CSA was associated with consistent increases in risks of later mental health problems. Exposure to CPA had weaker and less consistent effects on later mental health. These findings suggest that much of the association between CPA and later mental health reflects the general family context in which CPA occurs, whereas this is less the case for CSA. 相似文献
