109 Children were classified using the Ainsworth Strange Situation at 18 months. 81 children who were unequivocally classified as insecure/avoidant (A1, A2) or securely attached (B1, B2, B3) were used in this study. The children's parents reported on occurrences of problem behaviors at 24 months, 27 months, 30 months, and 48 months using several methods. The children were observed at 18 and 30 months in their homes with their families and in toddler playgroups during the same period. The only significant effect for attachment classification was that teachers and observers of the playgroups rated girls classified as insecure/avoidant as more difficult to deal with and as having more difficulty with peers than girls rated as securely attached. 相似文献

This study was designed to describe the changes in the social exchanges of young children with disabilities with their mothers and with a familiar playmate over a 16-month period. Thirty children were observed for 15-minute sessions with each partner for four data points. Data were analyzed using a modification of a coding system developed by Vandell and Wilson (1979) to determine changes in the frequency, complexity, and content of the social exchanges. Results indicated that children engaged in more exchanges over time, and that these exchanges became more completely social. In addition, children showed more vocal behavior and more object-related acts over the 16-month period of the study. 相似文献

Infants with Down syndrome (DS) represent a population in which new behaviors are acquired significantly more slowly than in nondisabled infants. We propose that infants' spontaneous movements hold a key to understanding the process of development—of integrating intrinsic dynamics and function. In this investigation, we compared the spontaneous leg movements of 10 infants with DS and 2 groups of nondisabled (ND) infants matched for chronological age and motor age. In contrast to common perceptions, we did not observe a significant difference in the frequency of movements between infants with DS and ND infants. But, infants with DS demonstrated significantly fewer of the most complex patterned leg movements, that is, kicking patterns. Further, the frequency with which both DS and ND infants kicked was significantly correlated with the age at which they began to walk. Biomechanical variables were identified, as well, that related to their emergent movement patterns. These data are consistent with Edelman's proposal that spontaneous movements that occur repeatedly in regions of the organism's functional work space facilitate the development of stable behavioral patterns and emphasize the role of the interaction of multiple subsystems in the emergence of new behaviors. 相似文献

Parents and teachers reported that 6- to 8-year-old boys with developmental delays were less able to regulate their emotions than nondelayed boys matched on chronological age. Compared to nondelayed boys, boys with developmental delays had more social problems, which persisted and increased over a 3-year period. Children's ability to regulate their emotions explained significant variance in their social problems after controlling for their developmental status. In addition, emotion regulation partially mediated the relationship between children's developmental status and their social problems. These results suggest that emotion regulation plays a significant role in the social problems of boys with developmental delays. Furthermore, increasing the emotional competence of these children may facilitate their peer relationships and, ultimately, their school adjustment. 相似文献
