Several key variables in the development and assessment of young children's sex role preference are examined in this study. A sample of 257 pre-kindergarten children (mean age, 59 months) and their mothers participated in this study. After obtaining information on each child's age, IQ, and his/her mother's employment status the It Scale for…

This paper attempts to clarify some of the issues raised in the author's earlier paper, "A Theoretical Perspective on the Relationship between Bilingualism and Thought" (Working Papers on Bilingualism, No. 1), as a response to Gerald Neufeld's critique, which appeared in No. 2 of the same series. The present paper argues that Neufeld mistakenly…

Claims in "The Bell Curve" that Head Start and other early intervention programs are a failure and a waste of funds depend on a notion of cognitive ability reduced to IQ. They ignore other studies that demonstrate the success of such programs and that, consistent with Piagetian views, recognize the interrelationships of cognitive,…

Poor readers who met low achievement and IQ-discrepancy definitions of reading disability (n=54) were compared with non-impaired readers (n=325) on development of eight precursor and reading-related skills. Results indicate no evidence for differences between the two groups of poor readers in the development on the eight skills, with three…

The objective of this study was to develop and evaluate two procedures for providing preschool education for rural 4-year-olds by using a mobile laboratory. The project used "readimobiles" to determine the effectiveness of a structured, psycholinguistically-based preschool curriculum on black, disadvantaged children. There were three…

Cognitive, academic, and behavioral characteristics of 42 children with learning disabilities were assessed from identification at age 6-7 to the age of 11.5. At endpoint, resource students showed a drop in verbal intelligence quotient and lower achievement compared to mainstreamed students, though there were no differences at the time of…

A study examined the impact of a gifted enrichment program on 80 Israeli students (grades 4-8) from disadvantaged neighborhoods. After program participation, girls' performance on an intelligence test was higher than boys'. While girls started out with slightly lower scores, they ended up with slightly higher scores than boys. (Contains…

Change in cognitive functioning is an important aspect of human aging and a key outcome in many medical conditions. However, cognitive change can rarely be measured directly, since prior cognitive data do not exist for most people. We examined the criterion validity and one-year stability of the difference between National Adult Reading Test…

The intellectual development of black college students on a predominantly white campus was examined using the Reflective Judgment model of post-adolescent intellectual development. The model posits a seven-stage sequence of changes in assumptions about the sources of certainty of knowledge, and shows how these assumptions affect the ways adults…

Results indicated significant associations between mental age and various indices of the retardates' role taking behavior. These associations remained significant…
