From a longitudinal sample of 202 children studied from birth to 8 years of age, two extreme groups were selected. One group had a more rapid development than normal and the other a slower development. A relationship between the development of abilities and weight and height increases was found for boys aged 4 weeks to 2 years and between the…

Literature on cognition is surveyed with a special emphasis on the development of academic skills in handicapped children. (Author/KM)

The development of moral judgment in 11-year-old girls is discussed in terms of the evaluation of role taking ability. (ST)

Two experiments sought to determine whether rehearsal strategies constitute a primary determinant to age-related changes in auditory short-term memory. (ST)

Subjects in grades 2, 6, and college were asked to sort 50 pictures according to several class labels, each with a functional equivalent. (ST)

The purpose of this paper is to present some evidence linking malnutrition to physical development, brain development, infection, environment, learning and behavior. (CS)

Assesses Vertical Home Start, a program which provided children with readiness enrichment over a period of three years while the children were from two to five years of age. Results indicate that there is little durability to short-term verbal gains. However, longitudinal assessment is advised since some scores do vacillate. (HMV)

Suggests that the use of anthropomorphic statements are appropriate when dealing with children operating at the preoperational and concrete levels. For these children anthropomorphic formulations are not only natural, but actually aid comprehension of the world theyobserve. (JR)

First and second graders (n=81) were randomly partitioned into experimental and control groups. The experimentals were given experiences in sorting and seriating objects. Significant treatment and grade effects (p.01) were found on a seriation test, but no significant relationships between classification and transitivity nor seriation and…

Three distinct, but overlapping, stages in measurement are identified as intuitive thinking, logical thinking, and formal operations. Three types of representation are body units, non-standard, and standard units. Instructional sequences and activities are suggested for grades 1-3 and grades 4-6 based on these considerations. (LS)

This study assessed the role of parental teaching in improving children's memory skills. Subjects were 32 parent couples, each with a 3- or 4-year-old child. Teaching sessions consisted of each parent helping his or her child memorize a 20-item set of pictures of familiar objects for a free-recall task. Verbal communications of each parent were…

Reported are studies which investigate children's understandings of concepts of symmetry and topology, area measure, limit and function, and logical inference. In each case, the mathematical concepts are analyzed in terms of their conceptual foundations. Tasks were created or adapted for testing the subconcepts at appropriate grade levels from K…

This paper offers a social learning explanation for age-related changes in children's cognitive functioning. Three hypotheses have been derived from the assumption of Piaget that structures play the preeminent role in cognitive development: (1) a child can not profit from or even appreciate experiences which are meaningful at a higher stage of…

Eight girls and 8 boys, 4 years of age, were individually administered two measures of role-taking skill (empathy and spatial egocentrism), a measure of classification ability and a measure of sociometric popularity. Activity during free play was also observed. Results support Smilansky's (1968) beliefs concerning the ontogenesis of play in young…
