To assess the premise that picture books are important transmitters of sex-role information, 206 picture books for children, ages 3 to 6, were analyzed. Three groups were formed: (1) titles published before the women's movement (1903-1965); (2) titles published after the women's movement (1966-1975); (3) titles chosen from a specialized nonsexist list of books about girls (1882-1973). Analyses indicated that children are presented with sex-typed book models: females, underrepresented in titles, central roles, and illustrations; males, overrepresented in instrumental pursuits and underrepresented in expressive activities. On the other hand, the third group of books featured mostly female characters and contained a predominance of instrumental models with a minimum of expressive activities. The data revealed that picture books today provide stereotyped models for young children to emulate.  相似文献

Effective cognitive-behavioral therapies for insomnia have been developed over the past 2 decades, but they have not been systematically evaluated in some clinical settings. While insomnia is common among veterans with mental health problems, the availability of effective treatments is limited. We report on the group application of a cognitive-behavioral therapy for chronic insomnia in a veteran population with significant comorbidity for both psychiatric problems and chronic medical conditions. Outcome measures were obtained for both sleep (via sleep diaries) and daytime functioning. Substantial posttreatment improvements were evident for measures of sleep consolidation, total sleep time, depression, anxiety, and fatigue. The unique suitability of the group therapy approach with this population is discussed. Controlled evaluations of the group cognitive-behavioral treatment for comorbid insomnia in this and other ambulatory settings are warranted.  相似文献

T he present study of three generations' families living together during a period of marked economic dislocation investigates whether supportive grandparents can ameliorate the negative effects of economic stress on parenting and on teen outcomes. The study focuses on harsh parenting and adolescent depression, which has been shown to be especially responsive to economic stress. Three hypotheses were investigated: (1) in extended families there is a link between economic adversity and adolescent depression that is mediated by harsh parenting; (2) grandparent support diminishes the relationship between economic pressure and harsh parenting; and (3) grandparent support diminishes the relationship between harsh parenting and adolescent depression. Data were collected from a community sample of 62 extended families with an adolescent during a period of marked economic dislocation in Bulgaria. Mothers, fathers, and adolescents completed questionnaires about perceived economic pressure, parents' harsh parenting, and perceived support of grandparents. Adolescents also completed a measure of self‐reported depression. Additional interviews were conducted with every eligible family member about family relations. Results showed that even though there was significant economic stress reported by parents, adolescents reported moderate levels of depression and low levels of harsh parenting by mothers and fathers. Correlation and regression analyses revealed that whenever respondents experienced support by grandparents, it made a difference for family members. More specifically, despite economic stress, mothers who experienced the support of grandparents tended to exercise less harsh parenting practices than mothers who lacked such support. Furthermore, when grandparents were supportive, harsh parenting was not associated with adolescent depression. These findings are discussed in the light of existing studies of families under economic pressure with a special focus on extended family relations and the role of cultural context.  相似文献

The authors analyze the influence of different sitting positions (ring and flexion) on the reaching performance (spatiotemporal variables) of full-term infants 6 and 7 months old. In addition, they correlated level of trunk control, measured by the Segmental Assessment of Trunk Control, with performance during reaching. The different sitting positions only influenced the reaching movements of 6-month-old infants, who showed the best performance in the ring position. However, this influence was observed only for the trunk displacement, deceleration time, movement units, straightness index and mean velocity. In contrast, there was no influence of positions on 7-month-old infants’ reaching performance. Regarding the correlations, it was observed that infants with more level of trunk control showed a better performance when reaching, regardless of position and the age assessed.  相似文献

Deaf children with cochlear implants (CIs) represent an intriguing opportunity to study neurocognitive plasticity and reorganization when sound is introduced following a period of auditory deprivation early in development. Although it is common to consider deafness as affecting hearing alone, it may be the case that auditory deprivation leads to more global changes in neurocognitive function. In this paper, we investigate implicit sequence learning abilities in deaf children with CIs using a novel task that measured learning through improvement to immediate serial recall for statistically consistent visual sequences. The results demonstrated two key findings. First, the deaf children with CIs showed disturbances in their visual sequence learning abilities relative to the typically developing normal-hearing children. Second, sequence learning was significantly correlated with a standardized measure of language outcome in the CI children. These findings suggest that a period of auditory deprivation has secondary effects related to general sequencing deficits, and that disturbances in sequence learning may at least partially explain why some deaf children still struggle with language following cochlear implantation.  相似文献
