Haroutunian defends points made in a paper (Educational Theory v30 n3) relating Jean Piaget's conception of knowledge to his biological view of equilibrium in response to criticism by William E. Doll, Jr. (Educational Theory, v31 n2). Haroutunian asserts that Piaget's theories permit evolutionary change only by chance mutation. (PP)

A model for viewing adolescent psychosocial development is outlined and used as a framework for reviewing literature. The model assumes that basic changes in adolescents' biological, cognitive, and social capacities reciprocally interact with the social settings of the family, peer group, and school/work to influence transformations in six areas…

The author discusses major premises of a paper, by Sophie Haroutunian (Educational Theory, v30 n3), that relates Jean Piaget's conception of knowledge to his biological theory of equilibrium. Doll argues that Piaget's theory of equilibration (striving for control over the environment) is not sufficiently appreciated by Haroutunian. (PP)

An evolution-based framework for understanding biological and cultural influences on children's cognitive and academic development is presented. The framework, which defines biologically primary and secondary classes of cognitive ability, is a foundation for examining current approaches to reform and mathematics instruction in the United States.…

Three language models (Staats, Lenneberg, and Piaget) are reviewed, and implications for reading are suggested. Staats' behaviorist stance maintains that imitation, mediation, generalization, and discrimination are key concepts in language learning behavior. Critics contest the importance of these concepts and claim that behaviorists cannot fully…

Despite considerable work concerning relationships between cognition and language in the second year of life, these relationships remain obscure. Clarification depends on resolution in at least three major areas. First, studies should be expanded beyond the scope of cognitive prerequisite models that have been difficult to conceptualize and that…

Summarizes research findings that challenge long-standing theories of infant cognition and motor development and proposes alternative theoretical models to describe skill acquisition during the first several years of life. Findings are discussed with respect to research in the area of infant speech physiology and production. (Author/CR)

This book presents an integrated theory of cognitive development in infancy and early childhood, emphasizing the role of language in memory, processing narratives, forming concepts, and understanding others' intentions. Chapter 1, "Language, Cognition, and Culture in Developmental Perspective," presents the experiential theoretical…

Sex differences in cerebral organization and functioning, and the apparent superiority of males in spatial ability are examined in this paper. Attention is given to several kinds of cognitive and perceptual tasks in which sex differences in spatial ability have been shown to exist; among these are tasks involving: (1) recall and detection of…

Concerned with what can be done to help produce more thoughtful, critical readers, this report first presents an historical overview of theories on the origin of language, referring to B. F. Skinner, Noam Chomsky, and Jean Piaget, among others. It then discusses biological reasons for the evolution of language and the impact of verbal language on…
