Little research has considered whether prenatal experience contributes to executive function (EF) development above and beyond postnatal experience. This study tests direct, mediated, and moderated associations between prenatal risk factors and preschool EF and IQ in a longitudinal sample of 1,292 children from the Family Life Project. A composite of prenatal risk factors (i.e., low birth weight, prematurity, maternal emotional problems, maternal prepregnancy obesity, and obstetric complications) significantly predicted EF and IQ at age 3, above quality of the postnatal environment. This relationship was indirect, mediated through infant general cognitive abilities. Quality of the postnatal home and child-care environments did not moderate the cascade model. These findings highlight the role of prenatal experience as a contributor to individual differences in cognitive development. 相似文献

This study examined the direct association between parental educational expectations and adolescents’ academic self‐efficacy, as well as the moderating influence of parental academic socialization messages. Participants were 148 Latino parent–adolescent dyads with the majority of Mexican origin (80.4%). Most of the parent participants were mothers (85.8%). Adolescents were 13 (46%) or 14 (54%) years of age, and 53% identified as female. Adolescents reported their academic self‐efficacy and perceptions of their parents’ educational expectations; parents reported on their academic socialization messages of shame/pressure and effort regarding academics. The results suggest that, after accounting for parents’ level of education and immigrant status, parental educational expectations were positively associated with adolescent academic self‐efficacy. This association was stronger among adolescents whose parents reported transmitting fewer messages of shame/pressure and academic effort. These results point to the importance of nuances in the content and type of academic socialization messages within Latino families. 相似文献

Students with Attention Deficit Hyperactivity Disorders (ADHD) frequently experience significant difficulty mastering basic academic skills. This meta‐analysis focuses on one specific potential area of learning difficulties for these students: namely, writing. To identify the extent and depth of the potential writing challenges faced by students with ADHD, we conducted a meta‐analysis comparing the writing performance of grade 1 to 12 students with ADHD to their normally achieving peers. We located 44 papers, yielding 45 studies with 87 effect sizes. The average weighted effect sizes showed that students with ADHD obtained lower scores than their normally achieving peers for writing quality (–0.78), output (–0.64), number of genre elements (–0.69), vocabulary (–0.76), spelling (–0.80), and handwriting (–0.62). Contrary to expectations, moderator analyses found that neither study quality nor the source from which ADHD students were drawn (i.e., school/community vs. clinic/hospital) accounted for variability above sampling error alone. 相似文献

The Calhoun (1962) paper has become a keystone article for the population density literature. Although a few research reports have followed, several aspects of population density and the behavioral phenomena identified by Calhoun have been ignored. For example, the consummatory behavior in-aggregate property of the behavioral sink is an unstudied phenomenon. Furthermore, although the literature on potential population reduction mechanisms has grown rapidly, the mechanisms of pup mortality (cannibalization by adults) as identified by Calhoun has not been pursued systematically. Finally, the question of whether social or spatial density or other factors constitute the potent variables in the development of social pathology has not been tested directly. The purpose of these five related experiments was to investigate aspects of these behaviors. 相似文献

Current developments in higher education strongly indicate that the way ahead in many disciplines is much closer co-operation between academia and industry. There is growing demand that recognition should be given to learning, irrespective of the environment in which it occurs.This article reflects on what are deemed to be essential components of a degree, and considers how they might be transformed into forms suitable for demonstration in the work environment. The discussion is supported by findings of a survey carried out in conjunction with a development - Structured Industrial Practice Studies - which integrates academic learning and learning in the work environment for full-time students. The findings, however, are of relevance beyond the particular model of learning and mode of attendance. There appears to be potential for achieving in the workplace aspects of courses which, in recent times, have been the prerogative of higher education establishments. However, such potential is variable between working environments and is dependent on higher education providers adapting to different structures in delivery. 相似文献

2 studies of word learning are reported. In Study 1, 24-month-old children and 2 adults played with 3 nameless objects. These objects were placed in a clear box along with a novel nameless object. The adults then displayed excitement about the contents of the box and modeled a new word. Comparison with a control condition indicated significant learning of the new word for the novel object. Study 2 followed the same procedure with one difference: the children played with the novel object while the adults were absent. Thus, at the time of the language model the target object was novel only to the adults, not to the children. Again subjects displayed significant learning of the new word. This last finding suggests that 24-month-old children understand that adults use language for things that are novel to the discourse context and that this novelty is determined from the speaker's point of view. 相似文献

The general nature of constructivist educators' views of teaching are overviewed first, followed by analysis of good strategy instruction in constructivist terms. That good strategy instruction is scaffolded teaching is particularly emphasized. Scaffolded teacher-student interactions necessitate that students experience unique instruction that stimulates a great deal of student construction of to-be-acquired competencies. The only important difference between good strategy teaching and teaching recommended by constructivist educators is in the explicitness of instruction, with relatively greater teacher input about what is to be learned during good strategy instruction. 相似文献
