Looking times of 36 children were recorded during subject-controlled presentation of slides in order to determine whether the existence of simple categories in 3-year-olds can be inferred from habituation data, and to determine any sex differences in conceptual generalization of habituation. Habituation was demonstrated over repeated presentation…

This paper examines some of the manipulative aids used in elementary mathematics instruction from the point of view of the cognitive structures needed to understand them. The number line, measurement activities, models for place value, and models for fractions are discussed. (SD)

This study attempts to raise and answer the question as to whether lateral specialization of the brain could explain some of the differences in persons at different stages of intellectual development from birth to adulthood according to Piaget's theory of individual development via sequential, qualitatively different stages.…

The multiordinal use of terms requires the ability to distinguish essential relationships and attributes from incidental ones. Until the child reaches adolescence, his tendency to confuse incidental and affective factors with those crucial to word meaning hinders his use of terms at all levels of abstraction. Korzybski's theory of multiordinality…

In this study of perspective taking and moral judgment 20 children (10 boys and 10 girls) at each age level between 4 and 10 years were given Feffer's Social Role-Taking Task, a spatial perspective-taking task and Damon's Test of Positive Justice.

This study explored the relationship between the mother-infant interaction and the concurrent perceptual-cognitive and intellectual status of the infant. One hundred and eight-nine 12-week-old infants were given a battery of perceptual-cognitive tasks, including the Mental Developmental Index (MDI) of the Bayley Scales, the Corman-Escalona Scales…

Originally designed for inner city children, ages 3-5 years, "Sesame Street" was designed to increase knowledge in the areas of: symbolic representation (pre-reading skills), cognitive organization which entails relational concepts, reasoning and problem solving, and the child and his world. This study examined the effects of the program…

Investigated was the compatibility between the intellectual abilities of students and the level of intellectual operations required by secondary level physics textbooks. Student intellectual levels were determined for 949 tenth-, eleventh-, and twelfth-grade students by administration of Piagetian tasks. Major concepts presented in physics…

This article states that children in the first grade have usually not developed the thought processes which would enable them to understand the typical first-grade math curriculum. (CD)

Discusses some advantages of multi-age grouping in group child care centers. (ED)

Discussed is the parents' role in providing training procedures to meet the developmental needs of blind infants. (Author/LS)
