Although children born preterm are at risk for neuropsychological impairments at school age and adolescence, including difficulties with visual motor integration, spatial/constructional skills, attention, arithmetic, and nonverbal executive functions, specific neuropsychological outcome has not been investigated adequately in preschoolers. Application of cognitive neuroscience tasks offers the opportunity to characterize early executive functions in young children born preterm. In a preliminary sample of 29 preschool children born preterm (M birth gestational age = 32.4 weeks), executive function outcome was compared to that of fullterm controls by contrasting performance on two prototypic delayed-response-type paradigms, Delayed Alternation and Spatial Reversal. Preschoolers born preterm correctly retrieved the reward on fewer trials on Delayed Alternation than did matched controls. Furthermore, preschool children born preterm used problem-solving strategies that included more perseverative errors than controls. These preliminary findings highlight the utility of cognitive neuroscience paradigms to understand neuropsychological outcome in preschool children born preterm and suggest areas of developmental vulnerability that may include dorsolateral prefrontal circuits. 相似文献

Gender-role conflict theory has suggested that women athletes will experience role conflict because they are attempting to enact both feminine and masculine gender roles, yet research findings have shown mixed support for this notion. The purpose of this study was to explore how women rugby players negotiate gender-role expectations and conflict as women participating in a traditionally masculine sport. Eleven Caucasian women, noncollege rugby players between the ages of 25 and 38 were interviewed. The results indicated that women rugby players perceived numerous discrepant gender-role expectations. In addition, three different types of gender-role conflict emerged; however, similar to previous findings, participants perceived conflicting expectations for their gender-role behavior more than they seemed to experience conflict about those expectations. Participants actively employed various strategies to resolve or avoid experiencing gender-role conflict. The resiliency displayed by the women athletes in coping with discrepant gender-role messages provides new considerations for gender-role conflict theory. 相似文献

How do stimulus size and item number relate to the magnitude and direction of error on center estimation and line cancellation tests? How might this relationship inform theories concerning spatial neglect? These questions were addressed by testing twenty patients with right hemisphere lesions, eleven with left hemisphere lesions and eleven normal control subjects on multiple versions of center estimation and line cancellation tests. Patients who made large errors on these tests also demonstrated an optimal or pivotal stimulus value, i.e., a particular size center estimation test or number of lines on cancellation that either minimized error magnitude relative to other size stimuli (optimal) or marked the boundary between normal and abnormal performance (pivotal). Patients with right hemisphere lesions made increasingly greater errors on the center estimation test as stimuli were both larger and smaller than the optimal value, whereas those with left hemisphere lesions made greater errors as stimuli were smaller than a pivotal value. In normal subjects, the direction of errors on center estimation stimuli shifted from the right of true center to the left as stimuli decreased in size (i.e., the crossover effect). Right hemisphere lesions exaggerated this effect, whereas left hemisphere lesions diminished and possibly reversed the direction of crossover. Error direction did not change as a function of stimulus value on cancellation tests. The demonstration of optimal and pivotal stimulus values indicates that performances on center estimation and cancellation tests in neglect are only relative to the stimuli used. In light of other studies, our findings indicate that patients with spatial neglect grossly overestimate the size of small stimuli and underestimate the size of large stimuli, that crossover represents an “apparent” shift in error direction that actually results from normally occurring errors in size perception, and that the left hemisphere is specialized for one aspect of size estimation, whereas the right performs dual roles. 相似文献

The present study examined the degree to which parenting attitudes and behavior (i.e., self-reported warmth, restrictiveness, and behavioral sensitivity as assessed during a freeplay session) were related to toddlers' development. Results showed a restrictive attitude was negatively related to social and cognitive development, whereas paternal sensitivity was positively related to aspects of social development that are less dependent on language skills (e.g., motor and daily living skills). Fathers of girls exhibited greater sensitivity in their freeplay interactions than fathers of boys. More globally, the present research demonstrates important relations between the parenting attitudes and behavior of low- to working-income African-American fathers and young children's development, and similarities to White, middle-income fathers. 相似文献

Various aspects of parental work schedules affect the opportunities and constraints that parents encounter when arranging care for their children. This study examined the extent to which the combination of couples’ work schedules was associated with their use of different types of child care, focusing on parental, formal, and informal child care. We considered multiple dimensions of couples’ work schedules, namely, the timing of work, schedule flexibility, and home-based telework. Data from a recent Dutch survey were used, including information about 1599 dual-earner couples with children aged 0–6 years. The results indicated that paid work during nonstandard hours increased the amount of parental child care that was provided by one parent while the other parent was working, whereas work during evenings, nights, and weekends decreased the likelihood of using both formal and informal child care. Results further revealed gender differences for nonstandard hours and schedule flexibility. We found stronger effects of mothers’ work schedules, indicating that a gender-neutral approach to parental work is not justified. These results indicate that the timing of parental work is important to consider when examining not only parental child care but also formal and informal child-care use. We provide recommendations for future research, specifically regarding the possible consequences for parental well-being. 相似文献

The purpose of this study was to determine the prevalence and individual risk factors of people who trade or sell sex among sexually active individuals seeking HIV and sexually transmitted infection (STI) testing. Using electronic agency records, an analysis of the characteristics of 5,029 youth and adults who voluntarily obtained HIV and STI testing was conducted. Multiple imputation procedures for missing data from 3 variables and logistic regression were conducted. A total of 128 individuals reported having traded sex. Nine variables had statistically significant associations with trading sex. Individuals who identified as White and female had lesser odds of trading sex, whereas individuals who were transgender, were living in a shelter, had been sexually assaulted, had a previous STI, had high-risk sex, or used drugs had greater odds of trading sex. Elevated levels of high-risk behavior in addition to sexual trauma should be considered in intervention research and community health practice. Implications for service providers and researchers are discussed. 相似文献

In the 1980s and early 1990s, more than 50,000 Iranian refugees moved to Sweden. The Swedish state attended to their immediate needs, providing housing, language training, and other types of support. Moreover, these migrants had almost immediate access to all the benefits of the Swedish welfare state including affordable healthcare, unemployment insurance, and free education up to and including the tertiary level. Despite the opportunities available to them in Sweden, many Iranian refugees have faced challenges, especially when trying to secure meaningful work. One of the strategies they have used to overcome barriers to entering the labor market is to leave Sweden for onward destinations which are seen as having relatively more to offer. This study explores the onward migration of Iranians from Sweden by way of a two-step mixed methods approach: in the first step, population register data is used to determine how onward migrants differ from those Iranians who stay in Sweden. In the second step, information from life history interviews conducted with onward migrants in London and Toronto is used to understand what motivates individuals to leave Sweden. Overall, the study finds that highly educated Iranians who have struggled to find employment in Sweden are the most likely to move on. Their precise motivations for doing so, however, are nuanced and complex and relate to more than just economic factors. 相似文献

Sensitizing Potential Jurors to Variations in Eyewitness Evidence Quality Using Counterfactual Thinking 下载免费PDF全文
Jurors often have difficulty evaluating eyewitness testimony. Counterfactual thinking is a type of mental simulation that informs causal inference. Encouraging jurors to think counterfactually about eyewitness factors may sensitize them to these factors' causal influence on eyewitness identification and testimony accuracy, improving their overall judgments (such as verdicts). One hundred twenty‐one undergraduate participants were randomly assigned to read a scenario containing either high‐quality or low‐quality eyewitness evidence and to evaluate eyewitness factors adopting either their default or a counterfactual mindset via a question‐order manipulation. Logistic regressions and analyses of variance revealed that a counterfactual mindset lowered perceptions of eyewitness accuracy and guilty verdicts (compared with the default mindset) when the evidence was poor; a counterfactual mindset, however, did not increase perceptions of accuracy and guilty verdicts when evidence was strong. We discuss possible mechanisms underlying these effects and identify several potential avenues for future research.Copyright © 2016 John Wiley & Sons, Ltd. 相似文献
