Located within the recently emerged field of researcher development, this article represents an attempt to make a key theoretical contribution to its knowledge base through a conceptual analysis. It presents as propositional knowledge an original theoretical model of the componential structure of researcher development, as interpreted and defined…

Research leadership, a much neglected area of educational leadership and management, is disadvantaged by having an underdeveloped and inadequate knowledge base. This article represents a contribution to this knowledge base through a conceptual analysis. It presents as propositional knowledge an original theoretical model of the componential…

Investigates relationships between family structure variables and 17 measures describing children's intellectual, psychosocial, and physical growth. Subjects were a 10 percent random sample of a Danish cohort consisting of children born in a Copenhagen hospital between September 1959 and December 1961; 857 subjects were followed to age 19.…

A comparison of the theories of Jean Piaget and William Perry (using individual interviews with college students) shows that the two theories outline different and independent processes for assessing intellectual development. (JN)

Based on research studies from fields of education, social organization, and logic, this article argues that the study of organization of knowledge has important implications for students' general intellectual development. Recurring stages of intellectual development are outlined, and implications for improving quality of library school education…

Discusses John Dewey's concept of curriculum, as applied in his Laboratory School. Describes the planning of the school and how its curriculum evolved over time. Identifies both Dewey's belief in educational specialization and his understanding of its limits. Notes the implications of Dewey's work for today's educators. (SG)

Defines life-span developmental psychology as the study of constancy and change in behavior throughout the life course. Advances metatheoretical view regarding development. Stresses focus on the dynamic and continuous interplay between growth (gain) and decline (loss). Examines structural contextual factors and study of range of plasticity in…

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…

Explains that from a prediction standpoint the confluence model is not very efficient. Very modest increments in accuracy are associated with family configuration variables once chronological age is covaried. Suggests that the major postulates of the theory be tested directly, within individuals and with longitudinal data. (Author/AS)

Studied the sleep state organization and EEG patterns at term date in 53 preterm infants as an index of the maturity and integrity of neurophysiological organization that may have implications for their later development. (HOD)

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)

Study looks at pigtailed macaque in the context of visual recognition problems adapted from a standardized test developed for use with human infants. Results demonstrate that the low-risk group easily differentiated novel from previously seen targets; the high-risk group gave no evidence of recognition. (Author/RWB)

This study examined the relationship between adaptive functioning and intellectual functioning in 18 children with autism and mental retardation and 20 children with mental retardation. The children with autism showed significantly more impairment in adaptive behavior composite scores, verbal reasoning abilities, socialization skills, and…

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)
