Kindergarten children were administered tests of inductive reasoning and field dependence and a series of perceptual egocentrism tasks. Results confirm a positive relation between field dependence and perceptual egocentrism; they also question the validity of the field-dependence construct in early childhood. (GO)

Investigated developmental trends in part-whole perception. The effects of the whole on the perception of small parts was greater at the kindergarten level than at the 4th grade; and there was a change in the perception of the parts so that they came to look like the whole in shape. (DP)

Nonoperational first graders were taught Piaget's horizontality concept. In comparison to control subjects, training group subjects significantly increased correct responses, maintained their gains, and transferred their training from a straight-sided jar to a round-sided jar. (Author/DB)

The association of locus of cerebral hemispheric specialization of spatial function with identity and equivalence conservation judgments was tested in a group of four- to six-year-old right-handed children (N=31). (Author/MP)

This study examined the hypothesis that perceptual errors on a task requiring subjects to take different viewpoints could be explained in terms of response bias. Results were consistent with response bias hypothesis: making an egocentric error is different from behaving in an egocentric manner. (Author/SB)

Attempts to clarify the basis for the unusual responses to observed movement by 7-year-old children, as compared to adults, discovered by Olum. Subjects were 40 first and third graders. Results indicate that these responses are genuine and that they go through a developmental evolution. (SDH)

This study was undertaken to determine the relative contribution of age, sex, and three stimulus features (board shape, block arrangement, and block shape) to perceptual accuracy on 39 board/block adaptations of Piaget's three-mountain task. (Author/SB)
