Children's performance on cognitive tasks is often described in categorical terms in that a child is described as either passing or failing a test, or knowing or not knowing some concept. We used binomial mixture models to determine whether individual children could be classified as passing or failing two search tasks, the DeLoache model room task and the Berthier et al. door task. The data support categorical classification of the children and suggest that the increase in average proportion correct with age is the result of an increasing proportion of children who can solve the tasks. Performance on the two tasks was concordant, and improving performance could be due to advances in a single psychological ability, such as cognitive control.

This article reviews recent sociocultural studies of families of children with intellectual disabilities to introduce the range of research conducted from this perspective and to highlight the methodological, conceptual, and theoretical contributions of this approach to the study of mental retardation. Sociocultural studies examine families within their cultural, historical, and sociopolitical contexts. This type of research is comparative across different cultural groups, but is not limited to such comparisons. Sociocultural studies use varied theories and methods, but they share a focus on families' coproduction of meanings and practices related to intellectual disability; families' responses and adaptations to disability; and how their understandings and experiences are shaped within larger social institutions and inequities. Sociocultural approaches take into account community contexts that matter to families with members with mental retardation or developmental delay, and they examine the broader systems that define and position individuals with disabilities and their families. As a whole, these studies provide a more experiential and holistic view of families' beliefs and adaptations within sociopolitical worlds, and offer new tools by which to study the families of children with developmental delays within and across different cultural groups. 相似文献

Mixed methods in family psychology refer to the systematic integration of qualitative and quantitative techniques to represent family processes and settings. Over the past decade, significant advances have been made in study design, analytic strategies, and technological support (such as software) that allow for the integration of quantitative and qualitative methods and for making appropriate inferences from mixed methods. This special section of the Journal of Family Psychology illustrates how mixed methods may be used to advance knowledge in family science through identifying important cultural differences in family structure, beliefs, and practices, and revealing patterns of family relationships to generate new measurement paradigms and inform clinical practice. Guidance is offered to advance mixed methods research in family psychology through sound principles of peer review. 相似文献

Mixing qualitative and quantitative research in developmental science: uses and methodological choices 总被引:1,自引:0,他引:1
Multiple methods are vital to understanding development as a dynamic, transactional process. This article focuses on the ways in which quantitative and qualitative methodologies can be combined to enrich developmental science and the study of human development, focusing on the practical questions of "when" and "how." Research situations that may be especially suited to mixing qualitative and quantitative approaches are described. The authors also discuss potential choices for using mixed quantitative- qualitative approaches in study design, sampling, construction of measures or interview protocols, collaborations, and data analysis relevant to developmental science. Finally, they discuss some common pitfalls that occur in mixing these methods and include suggestions for surmounting them. 相似文献

The impacts of New Hope, a program to increase parent employment and reduce poverty, were measured 5 years after parents were randomly assigned to program or control groups. New Hope had positive effects on children's school achievement, motivation, and social behavior, primarily for boys, across the age range 6-16. In comparison to impacts measured 2 years after program onset, effects on achievement were robust, but effects on social behavior were reduced. The program produced improvements in family income and use of organized child care and activity settings, suggesting possible pathways by which the New Hope package of policies influenced children's behavior. 相似文献
