Estimates confluence model of intellectual development for a within-family sample of 321 children from 101 transracial adoptive families. Mental ages of children and their parents and birth or adoption intervals were used in a nonlinear least-squares estimation procedure to obtain children's predicted mental ages. Results suggest efficiency of the…

An increase in the cognitive restructuring aspect of field-independence was found to be associated with an increase in formal operational thought in 11- to 12-year-olds who were given materials designed to achieve this result. Materials used (including computer programs) are described in an appendix. (JN)

This paper demonstrates a method for constructing long variables using items that elicit partically correct responses across ages. Long variables may be defined by students at different ages (year levels) attempting common items within a test containing other items considered to be appropriate for each age or year level. A developmental model of…

Explores age differences (6 to 22 years of age) in conceptions about the nature of the skills required by verbal and nonverbal (abstract) intelligence tests. (HOD)

Observes 75 first- and third-grade children in their classroom mathematics seatwork to test assumptions drawn from Vygotsky's theory about the development of private speech and its relationship to task performance, attention, and motor behaviors accompanying task orientation. (HOD)

The Perry scheme of intellectual and ethical development has become widely used in a range of academic disciplines and such areas as career training and faculty consultation. However, current measurement techniques for the scheme, whether interview format or paper and pencil measures, do not adequately address issues related to assessing cognitive…

Investigates levels and patterns of intellectual development of 131 socioeconomically disadvantaged children in university-based intervention group day care or community day care, or with little or no day care. Results suggest that high quality day care may positively change the intellectual development of socioeconomically disadvantaged children.…

A four-and-a-half-year longitudinal experiment reconsidered the contribution of organic impairment to the genesis of mild mental retardation among disadvantaged children. It was hypothesized that nonoptimal perinatal conditions might result in deficits that increase a child's vulnerability to environmental risk factors. Study results supported the…

Argues that, even for young children, analogies offer conceptual models for supporting the development of understanding. Compared children's understanding of current electricity after instruction with and without the inclusion of analogies. Children receiving the analogies exhibited a broader understanding, especially concerning the process of…

Reports on the results of an experiment testing 58 elementary school students tasked with chronologically ordering a set of nine historical pictures and thinking aloud about their efforts. Provides increased evidence regarding the kind and sources of children's historical knowledge and how they deploy that knowledge. (MJP)

The Infant Health and Development Program was an eight-site randomized controlled trial of comprehensive early intervention for low birthweight, premature infants from birth to age three. Higher mental development and IQ were associated with high levels of intervention participation at 24 and 36 (but not 12) months. A dose-response relation…

Summarizes interviews with British West Indies children concerning the production of art and the role of the artist. Demonstrates that children's perceptions undergo a shift from naive realism (pretty things make pretty pictures) to a more interpretive stance (the artist's efforts define the final product). (MJP)

Uses test questions from the Basic Economics Test (BET) to reveal that elementary students are capable of understanding economics concepts. Maintains that neither ethnic background nor parental income makes a difference in economic learning. The most statistically significant determinant of improved scores was the extent to which a concept was…

Provides an overview of the research literature concerning the development of graphic art skills, relevant instructional methods, and the specific use of visual models as an instructional method. Pertinent findings, relevant methodological issues, and major conclusions are all discussed. Briefly addresses the viewpoints of gestalt and learning…
