This study explores the extent to which medical and sociodemographic variables and cognitive and language skills are associated with executive function (EF) skills in neonatal intensive care unit (NICU) graduates at 24 months of adjusted age. We explored cognitive, language, and EF skills in 42 NICU graduates who participated in a NICU follow-up programme clinic. The association between risk factors and EF and the completion of the EF assessment were explored. Correlational analyses revealed that child gender was associated with EF scores. Analyses revealed cognitive skills, language skills, and multiple gestational births were associated with EF assessment completion. Our findings are among the first to examine EF skills in NICU graduates as young as 24 months of age using a multidimensional, child completed measure. Implications for NICU follow up programmes, the consideration of early interventions aimed to positively affect EF skills, and considerations for future studies are discussed.  相似文献

The current study aimed to understand how sex differences in the timing of hypertension onset contribute to early midlife risk for cognitive decline that may differ by sex and whether sex-dependent advantages in normotensive populations are influenced by the presence of hypertension. One hundred and ninety-five adults aged 45–55 from the New England Family Study underwent neuropsychological testing to assess attention, executive function, and memory. Physician-diagnosed hypertension status was self-reported via questionnaire. Mid-adulthood hypertension was associated with worse performance on measures of attention and memory, but the cognitive domains impacted varied by sex. Hypertension was associated with only attention in men, whereas in women it was associated with attention and associative and working memory. Sex differences in midlife cognitive performance found in normotensive adults were attenuated in those with hypertension. Our results underscore the importance of accounting for sex when assessing the impact of hypertension on midlife cognition that could be indicative of later decline and risk for cognitive impairment and dementia, given hypertension is an independent risk factor.  相似文献

The authors examined the effects of heavy adolescent marijuana use on employment, marriage, and family formation and tested both dropping out of high school and adult marijuana use as potential mediators of these associations among a community sample of African Americans followed longitudinally from age 6 to age 32-33. They used propensity score matching to reduce selection bias when estimating the effects of heavy adolescent marijuana use. Logistic regression results on the sample matched on sex, and early demographic and behavioral variables showed that adolescent marijuana use has adult social behavioral consequences: Use of marijuana 20 times or more during adolescence was associated with being unemployed and unmarried in young adulthood and having children outside of marriage for both males and females. Dropping out of high school and more frequent adult marijuana use seem to be important parts of the pathway from adolescent marijuana use to negative life outcomes.  相似文献

The present investigation examined the relationships for scores on the Stroop Color and Word Test with measures of reading and language achievement within an adult population. The Stroop Color and Word Test, Nelson-Denny Reading Test, Woodcock-Johnson Psycho-Educational Battery-Revised, and Wide Range Achievement Test-3 were administered to 99 men ranging in age from 18 to 27 years. Pearson product-moment correlations indicated that the Stroop Word task was positively associated with scores on the WRAT-3 Spelling task, the Woodcock-Johnson Basic and Broad Reading tasks, and the Nelson-Denny Rcading Rate and Comprehension tasks. These and other significant relationships were discussed in terms of possible implications regarding the assessment of reading achievement.  相似文献

Examined whether children who were maltreated by caregivers were more likely to bully others and to be at risk for victimization by peers. An additional focus was to investigate emotion's role in bullying and victimization among children at risk. Participants were 169 maltreated and 98 nonmaltreated boys and girls attending a summer day camp for inner-city children. As predicted, maltreated children were more likely than nonmaltreated children to bully other children. Bullying was especially prevalent among abused children who experienced maltreating acts of commission (physical or sexual abuse). Maltreatment also placed children at risk for victimization by peers. Gender did not moderate these findings, in that maltreated boys and girls appeared to be at similar risk for bullying and victimization. As expected, both bullies and victims evidenced problems with emotion regulation. Furthermore, logistic regression analyses suggested that emotion dysregulation made a unique contribution toward differentiating bullies and victims from children who did not evidence bully-victim problems. In addition, maltreatment's effects on children's risk for bullying and victimization were mediated by emotion dysregulation.  相似文献

Research is important to validate clinical services, provide information on the effectiveness of practice techniques, and develop the knowledge base of a clinical profession. Genetic counseling students from American Board of Genetic Counseling (ABGC) accredited training programs were surveyed to determine their career research interests and interest in pursuing a hypothetical doctoral degree in genetic counseling. Genetic counseling program directors were surveyed to assess the emphasis on research training within their programs. A substantial number (46%, n = 92) of genetic counseling students are interested in performing research in their careers and many (40%, n = 80) would pursue a doctoral degree in genetic counseling if it was available. Students and directors from programs with a thesis requirement reported a significantly higher emphasis on career research preparation than those from programs without a thesis requirement. The results of this study indicate that future genetic counselors are interested in contributing to the research base that will advance the field. This study suggests a need to strengthen research training within ABGC accredited graduate programs and explore the development of a doctoral degree option in genetic counseling.  相似文献

Previous research suggests that coping styles are modestly heritable and that this genetic influence is shared in large part with genetic influences on personality. To test this hypothesis, we estimated the heritable basis of the Coping Inventory for Stressful Situations in a sample of 91 monozygotic and 80 dizygotic twin pairs. Task-oriented, emotion-oriented, and social diversion coping styles were modestly heritable (h(2)=.17 to .20), whereas the use of distraction appeared to be influenced solely by environmental factors. Multivariate analyses showed that genetic contributions to coping styles were, at best, only modestly related to genetic contributions to personality (r=-.03 to .35). Environmental contributions to personality were unrelated to environmental factors in coping style. These results suggest that coping style is not merely a manifestation of basic personality traits but does support the possibility that the genetic factors in personality influences have a modest influence on an individual's preferred coping style or strength (e.g., rigidity vs flexibility).  相似文献

The author examines British and American scientific psychology's portrayal of natural and ideal masculinity and femininity in the late 19th century to show how purported differences in emotion and reason were critical to explaining the evolutionary foundation of existing social hierarchies. Strong emotion was identified with heterosexual manliness and men's purportedly better capacity to harness the power of emotion in the service of reason. "Feminine" emotion was portrayed as a comparatively ineffectual emotionality, a by-product of female reproductive physiology and evolutionary need to be attractive to men. The author argues that constructions of emotion by psychology served an important power maintenance function. A concluding section addresses the relevance of this history to the politics of emotion in everyday life, especially assertions of emotional legitimacy.  相似文献

Considerable evidence has indicated that group-based physical activity may be a promising approach to reducing and preventing age-related illness. However, this research has not examined the mechanisms by which cohesion may impact on behaviour. The purpose of the present research was to utilise the theory of planned behaviour to investigate the mechanism by which group cohesion may affect physical activity intention. Participants were recruited from an existing physical activity intervention studying the effects of group cohesion on physical activity behaviour. The outcomes of this intervention are reported elsewhere. This paper presents data from a sub-sample of the intervention population (N=74) that examined the mediating relationships between the theory of planned behaviour and group cohesion on physical activity intention. Analyses showed that attitude and perceived behavioural control mediated the relationship between specific group cohesion concepts and physical activity intention. The direct measure of subjective norm failed to display a mediating relationship. The mediating relationships displayed between attitude and perceived behavioural control and physical activity intention provide insight into potential mechanisms by which group cohesion may affect behaviour.  相似文献
