First and fifth graders sorted cards into two piles based on the orientation of a T figure. Sorting took place in the presence of irrelevant information which did or did not contrast in line slope with the target, or in the absence of irrelevant information. (Author/JMB)

The ability of 7-, 8-, and 9-year-olds to understand proverbs was examined by having subjects compare each proverb against two thematic pictures: a nonliteral correct interpretation of the proverb and a foil. The results, which contradict the literature, showed consistent above-chance performance across subjects, ages, and proverbs. (Author/JMB)

Eight operationally defined "feminine" gestures were recorded for 48 elementary school aged boys and girls while they individually performed a standardized play task. Results showed a significant overall difference between the sexes with three specific gestures discriminating significantly between the sexes. (Author/JMB)

Examined the ability of children of different ages to encode and retrieve from memory descriptions of aggressive and withdrawn behavior displayed by hypothetical peers. Descriptions of two hypothetical peers were read aloud to the children studied. (PCB)

Studies investigated the development of children's ability to differentiate what they see from what they know in the context of conceptual perspective taking. Two developmental levels accounted for children's performance when they were asked about a naive observer's knowledge of the identity of objects. Perspective awareness training improved…

A developmental progression in 6-, 8-, and 10-year-old children's use of strategies for gathering information was revealed in a study involving partial recall, total recall, and similarity/difference judgments. When subjects chose stimuli for exposure from an array, older children showed more ability to match strategy to task demands. Strategy…

Examines the development of integration and comprehension monitoring in four-, five- and eight-year-olds. Children listened to stories containing a nonspecific premise, two sentences that converged on an interpretation of the premise, and an anomalous sentence. Results were interpreted as evidence for three developmental levels of integrative…

Children, ages three, five, and seven, were asked to evaluate a series of children's drawings for their own likes and dislikes and for the likes and dislikes they imagined for individuals older and younger than themselves. Results suggest that children as young as three can judge drawings for others differently from the way they judge them for…

Four experiments investigated three- and four-year-old children's knowledge of projective size-distance and projective shape-orientation relationships. Results indicated that preschool children's understanding of these relationships seems at least partly cognitive rather than wholly perceptive, providing further evidence for the acquisition of…

The purpose of present experiments with subjects approximately three, five, and seven years of age was to provide additional evidence for the obviousness of the generative transmission principle and to provide initial evidence for the secondary principles of absence and facility. Empirical support was found for each of these selection principles,…

Investigates developmental changes in adopted and nonadopted children's knowledge of adoption. A total of 200 children ranging in age from 4 to 13 years participated. Results indicated clear developmental trends in children's knowledge of the nature of the adoptive family relationship, as well as in their understanding of the motivational basis…

Delay/response inhibition in the presence of an attractive stimulus and compliance with maternal directives in a clean-up task were observed among subjects 18, 24, and 30 months of age. Results suggested (1) achievement of self-control is a major developmental accomplishment, and (2) individual differences in self-control emerge and are…

Studies development of auditory temporal acuity in 56 children aged 6 to 12 years and in 8 adults. Improvement in temporal acuity with age was attributed to development of sensory processes and not to age-related changes in nonsensory factors. (Author/BE)
