We investigated the relation between children's numerical-magnitude representations and their memory for numbers. Results of three experiments indicated that the more linear children's magnitude representations were, the more closely their memory of the numbers approximated the numbers presented. This relation was present for preschoolers and…

Background: Children ordinarily begin their formal education at the age when the great majority of them are capable of understanding the role of addition and subtraction in changing number. In determining critical differences they can apply the oddity principle--the first "pure" abstraction that children ever develop--understanding that…

Children (N=32) between 6 and 12 years of age were given Derry Death Concept Scale, Peabody Picture Vocabulary Test, and subtests from Wechsler Intelligence Scale for Children-Revised. Correlations indicated that level of death concept development was related to age and verbal-conceptual mental development. Socioeconomic status and death-related…

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)

Abstracts of two symposium papers are provided, giving: (1) the results of a study of the effect of child-rearing practices on the cognitive development of children under 5 years of age in Jakarta; and (2) the results of an investigation of West German preschool children's preferences and abilities in relation to conceptual styles. Comparing 100…

Kindergarten, first and second grade children participated in a study of the development of conservation of equality and inequality. (BD)

The Sigel Object Categorization Test (SOCT) is used for studying classification abilities in young children, the criteria for which is considered indicative of both cognitive ability and style. The test consists of two types of stijuli--one set of 12 relatively familiar three-dimensional objects and a second set of colored photographs of these…

Three socioeconomic classes of rural students ages 6 to 18 were interviewed about their conceptions of the rich and poor and economic inequality. The 114 students in the sample were divided as follows: (1) middle class, 23; (2) working class, 61; and (3) lower class, 30. Responses of the students are analyzed according to Leahy's categories of…

The Spontaneous Numerical Correspondence Test is an adaptation of a Piagetian procedure. Here the tester sets out an array of blue ceramic tiles and, providing the child with his/her own box of 15 blue and 15 red tiles, asks the S to take out the same number. The task is repeated four times: twice with 7 tiles, once with 8, and once with 10. In…
