Findings indicate that (1) development of probability reasoning can be shown by an increasing monotonic trend with age, (2) verbal tests assess different aspects of this development than do nonverbal tests, (3) Piaget's ontogenetic age brackets are accurate, and (4) sex and intelligence are not significant variables. (MH)

Theory and research concerning early adolescent self-concept and self-esteem indicate that: (1) many early adolescents' cognitive changes affect dramatically the way they see and evaluate themselves; (2) a variety of new significant others are involved in early adolescent self-concept; and (3) changes taking place during adolescence are not as…

Proposes that the whole notion of equating time in a classroom with the quality of education is a semantic fiction; describes three perspectives on the learning process in children that provide an alternative to the "fixed schedule" metaphor. (GT)

Provides data incongruent with Piaget's idea of a concrete operational stage. Shows no clear-cut termination of preconceptual thinking and no simultaneous conceptual development in the three content areas (number, space, and time). (Author/RL)

Focuses on three main issues emerging from studies of conceptual development: (1) young children's naive theories of the world; (2) how innate constraints in conceptual development work; and (3) how innate and sociocultural constraints are integrated. Maintains that early development of core domains of thought (naive psychology, physics, and…

Two marble-and-ramp experiments investigated whether a simple-to-embedded-rules account can explain changes in children's causal reasoning. Results indicated that the same difference between three- and four-year olds in the prediction experiment appeared in the action experiment, suggesting that the same rules may underlie causal action as well as…

Examined the developing relationships between false belief understanding and an awareness of the individualized nature of personal taste as well as a maturing grasp of the interpretive character of the knowing process. Results indicated that the concept of interpretation appears to involve a more complex and significantly later arriving…

Examined evidence for transitions in first and second graders' analogical reasoning, over a six-month period. Found strong evidence for bimodality in test performance frequency distributions and weaker evidence for inaccessibility in frequency distributions. Transitional subjects showed a temporary increase of inconsistent solution behavior and…

Reviews literature on music perception and cognition in the first year of life and examines their contribution to domains such as child development and music education. Focuses on studies examining musical features and the uses of music in the everyday life of infants and their caretakers. Critiques previous and current literature. Discusses…

Investigated the relationships of physical activity levels and psychomotor, psychosocial, and cognitive development among Turkish elementary school students. Student evaluations indicated that physical activity level was an important factor in determining student psychomotor development, but it was not important in determining psychosocial and…

Examines strategies for studying individual differences in infant behavior from the standpoints of the distinction between individual differences and developmental function and the need to study change with multivariate techniques. These themes are applied to the study of mental development, behavior genetics, temperament, and attachment. (RJC)

In response to a previous paper (EC 212 858) regarding the neurodevelopmental evidence for the basis of dyslexia, this paper suggests further concerns in the areas of cognitive measurement, the relationship between cortical-functional organization and child development, and lack of operational definitions in the study of the dyslexic syndrome. (DB)

Investigates the relationship between 24 children's experiences in their second year, their mental and emotional disposition before and after the second year, and their motivational competence. Type and quality of experience were related to mental and emotional disposition. (RJC)

Observed social interactions of 110 Embu children in rural Kenyan community bimonthly between 15 and 30 months of age. Found children who talked frequently, and whose vocalizations were responded to, performed better on assessment measures and showed more positive affect than children who had fewer social interactions or were carried a great deal.…

Major events in the maturation of the central nervous system (CNS) are reviewed relative to milestones for communication, speech, language, and cognition. Early insults to the CNS and their neuropsychological consequences are discussed. The role of patterns of myelination and dendritic branching to evolving stages of language and cognition are…
