This chapter first presents a review of research on the development of adopted children, focusing on meta‐analytic evidence and highlighting comparisons between adopted children with and without histories of early adversity. Some methodological issues arising from this literature are considered as well. Second, 7 longitudinal studies of adopted children's development are described, and the convergence of findings across the longitudinal studies and with the cross‐sectionally based meta‐analytic evidence is discussed. Third, the role of the adoptive family in supporting adopted children's development is explored.  相似文献

Children raised in institutions frequently suffer from a variety of behavioral, emotional, and neuropsychological sequelae, including deficits in attention, executive functions, disorders of attachment, and in some cases a syndrome that mimics autism. The extent and severity of these disorders appear to be mediated, in part, by the age at which the child entered and, in some cases, left the institution. Here we review the neurobiological literature on early institutionalization that may account for the psychological and neurological sequelae discussed in other chapters in this volume.  相似文献

The present study examined the relations of Chinese word reading and writing to both maternal mediation of writing and a number of metalinguistic and cognitive skills in 63 Hong Kong Chinese kindergarteners. The whole process of maternal mediation of writing, in which mothers individually facilitated their children's writing of 12 two‐character words in their own ways, was videotaped. This study replicated and extended previous work on the cognitive strategies mothers use to help children in writing Chinese words. Mothers' typical mediation strategies were positively and significantly associated with both children's independent word reading and writing. In addition, maternal mediation of writing was uniquely associated with Chinese word reading, but not word writing, even with metalinguistic and cognitive skills, including phonological awareness, morphological awareness, orthographic processing and visual knowledge, statistically controlled. Findings underscore the importance of mothers' early scaffolding in facilitating children's literacy acquisition.  相似文献

The acquisition of reading skills is known to rely on early phonological abilities, but only a few studies have investigated the independent contribution of the different steps involved in phonological processing. This 1‐year longitudinal study, spanning the initial year of reading instruction, aimed at specifying the development of phonological discrimination, awareness and various aspects of phonological memory and at assessing their respective contributions to early reading acquisition. Our results show an increase in performance at each phonological processing step, but also suggest a qualitative evolution in their relative importance. Hierarchical regression analyses indicate that reading skills are mainly predicted by phonological awareness measured at the kindergarten stage and, subsequently, by phonological memory abilities measured at the end of first grade. More precisely short‐term memory for serial‐order information seems to contribute to the development of decoding abilities, while phonological knowledge stored in long‐term memory seems to influence word recognition.  相似文献

The development of interest in reading and its relationship to reading ability was examined longitudinally in 117 children in Grades 1–3. Interest in reading was measured by eight items from the Elementary Reading Attitude Survey. Less able readers had lower interest in reading, but their development was parallel to that of more able readers. Interest in reading in Grade 1 was weakly correlated with Grade 3 reading ability, but correlations were lower for interest measured in Grades 2 and 3. Hierarchical regression analyses indicated weak and inconsistent effects of reading interest on reading ability after controlling general cognitive ability, SES, phonological awareness and naming speed. It is concluded that interest in reading has only a weak relationship to reading ability in the early elementary years, and that much of that relationship overlaps with the effects of other more powerful predictors.  相似文献

Learning about foreign language (FL) cultures is becoming an important objective in the FL curricula and national standards of different countries throughout the world. The purpose of the study was to examine the effects of the cultural portfolio project on: (1) students' concept development in their perceptions of the target language culture and their own; (2) students' evaluation of stereotypes towards English‐speaking cultures; and (3) students' self‐awareness and perception of EFL (English as a foreign language) and cultural learning process. Data were collected from students' cultural portfolio projects, classroom observation, and interviews. Results indicate that through the cultural portfolio project, students engaged in active learning, gained insight into specific aspects of the target language cultures and became more aware of the diversity within these cultures, and developed their ability to think critically instead of automatically accepting cultural information.  相似文献

The study examined the predictive value of adolescents’ personality trait ratings by different groups of informants in explaining academic achievement [grade point average (GPA)] while controlling for students’ sex and their mothers’ education. The Inventory of Child/Adolescent Individual Differences was employed as a measure of students’ personality traits at the end of elementary schooling (mean age = 14.7 years) and two years later when the participants attended secondary schools. The trait ratings were obtained through self‐, maternal and peer reports at both measurement occasions. They explained substantial portions of unique variance in the students’ GPA concurrently, and over time. Ratings by each of the three groups of informants had an incremental validity over one another in predicting school grades. Among personality variables, conscientiousness and low extraversion were consistently predictive of GPA.  相似文献

This study shows that professional identity should not be viewed as a composed variable with a uniform structure. Based on the literature and previous research, we view teachers’ job satisfaction, self‐efficacy, occupational commitment and change in the level of motivation as indicators of teachers’ professional identity. Using two‐step cluster analysis, three distinct professional identity profiles have empirically been identified, based on data of 1214 teachers working in secondary education in the Netherlands. These profiles differed significantly regarding the indicators of teachers’ professional identity. Teachers belonging to the found profiles did not significantly differ in their amount of experience.  相似文献

The early identification of young children's special educational needs (SEN), as well as the development of specific strategies to support those children identified with special needs, are increasingly recognised as crucial to facilitating good adjustment to school and to ensuring that such children are helped to reach their full potential in education. Using a large national sample of young children in England whose developmental progress was followed up from pre‐school, this study investigates which child, family, home and pre‐school factors can be viewed as risk or protective factors for later SEN‐status at age 10. The experience of high‐quality pre‐school education is shown to reduce the likelihood of a child being identified as experiencing SEN in the long run. Teachers’ assessments of SEN are found to be strongly related to children's reading and mathematics attainment, but other factors also predict SEN, including a child's age within a year group.  相似文献
