The authors examined effects of feedback and explanation on false belief performance. Thirty-three children (42-54 months; 15 girls, 18 boys) were randomly assigned to four treatment conditions: explanation, feedback, feedback researcher explains, and feedback child explains. Children completed false belief tasks during pretraining, 8 training…

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)

The present study was designed to assess the preschool's contribution to the social, physical, and cognitive development of children in a normal, upper-middle socioeconomic level community. (BD)

Mothers were asked to predict their children's responses to standardized intelligence test items. Negative correlation was expected between inaccurate maternal knowledge of children's ability and degree of children's psychological development. False maternal predictions correlated - .80 with correct children's responses. Nearly all of the…

Investigated developmental differences in males' (ages 3-20) descriptions of video scenes in which various interpersonal situations were depicted. Alternative paradigms for study besides egocentrism-decentering approaches are discussed. (DP)

This study tested the hypothesis that objective and subjective responsibility responses in moral judgment may be formally equal forms of cognitive organization. Results showed that subjects acting as offenders gave subjective responsibility responses; the same subjects acting as offended gave objective responsibility responses. Thus, subjects'…

The authors examined aspects of reliability and validity of the Goode-nough-Harris Draw-A-Person Test (DAP; D. B. Harris, 1963). The participants were 115 seven- to nine-year-old students attending regular or special education schools. Three judges, with a modest degree of training similar to that found among practicing clinicians, rated the…

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)

Summary scores for behaviors rated on Bayley's Infant Behavior Record were obtained by summing sequential ratings for same-sex twins participating in a longitudinal study. Composite scores were calculated for two behavioral clusters - one composed of behaviors related to primary cognitions and the other of behaviors related to extraversion.…

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)

This study was designed to provide empirical support for viewing personality development from a cognitive framework. With controls established for IQ and socioeconomic status, 75 children between 6 and 15 years old were classified by level of cognitive functioning according to Piaget's system. (CS)

In a study of charitable behavior, 187 kindergarten through sixth grade Caucasian boys and girls were given the opportunity to share candy with children (1) described as similar to them, (2) with children described as dissimilar and needy, or (3) with both. (BD)
