Children's first mathematics concept is their understanding of the quantities represented by number words (cardinal value), and the age at which they achieve this insight predicts their readiness for mathematics learning in school. We provide the first exploration of the factors that influence the age of becoming a cardinal principle knower (CPK),…

The formal operations skills and problem solving performance of 60 gifted girls (grades 4 through 6) were investigated. Ss were given Piagetian tasks which involved conservation of mass and weight, use of proportion, oscillation of the pendulum, and projection of shadows. Among findings were the following: (1) no relationship between IQ and either…

Investigated four hypotheses formulated by Jensen with regard to his theory of the relationship between cognitive abilities and socioeconomic status. Preschool children identified in the upper SES level performed with more accuracy on both levels of tasks as defined by Jensen. (Author/SDH)

This study, which is a partial replication and validation of the 1962 Laurendeau and Pinard study of causal thinking, investigates cross-cultural differences among three age levels of Canadian and American school children in the development of causal thinking. Also studied is the relationship between level of development of causal thinking and…

Investigated the general relationship between children's performance on social and physical measures of cognitive functioning, possible sex differences in performance on the two types of tasks, and the relationship between boys' and girls' performances on these tasks and age and IQ. (SDH)

This overview reviews a program of interlinked cross-sectional and longitudinal investigations of the nature of cognitive development in infants and young children with Down's Syndrome. The research falls into three groupings: object concept studies, operant learning experiments, and IQ studies. Early results suggest a common learning style which…

The study was undertaken to determine the possibility of a relationship between the selected traits of cognitive ability, conceptual development, emotional maturity, and perceptual-motor development in disadvantaged kindergarten children, since the knowledge of the relationship between traits might make it possible to strengthen a child's…

Six mildly and moderately retarded children (ages 6-8) were instructed in the Piagetian constructs of unidimensional classification and/or seriation using the "Piacelleration" learning set technique. After one semester, subjects made significant gains on: classification and seriation tasks, the Peabody Picture Vocabulary Test, and the…
