This study investigates children's metarepresentational competence (MRC) with regard to listening to and making sense of simple sonic stimuli. Using diSessa's (2002) seminal work on MRC in mathematics and sciences as background, it aims to assess the relative importance children attribute to several criteria for representational adequacy…

Children 5 to 11 were given Piagetian spatial perspective tasks in a study of the development of egocentrism. Results indicated a more complex development of egocentrism than earlier Piagetian studies have suggested. (ST)

Class-inclusion in first grade children was studied by using part-whole comparisons of families of stimuli (e.g., dogs). Results indicated that it was easier to make part-whole comparisons for the family relation than for the class-inclusion relation. (ST)

This study investigated the development of perceptual, cognitive, and affective perspective taking in 167 kindergarten through sixth grade children. Task intercorrelations were low, nonsignificant, and inconsistent, supporting the view that perspective taking is a multidimensional social-cognitive construct. (JMB)

The relationship between children's perceptual, cognitive, and affective perspective-taking scores and their cognitive perspective-taking scores gathered one year later was assessed. Subjects were 56 kindergarten through third-grade children. (Author/JMB)

The effects of perceptual and cognitive factors on information processing in visual periphery were studied in 5- and 8-year-old children and in adults. Subjects judged either the similarity (Study 1) or identity (Study 2) of geometric forms. (Author/SB)

The relationships between perception and conservation of length were investigated in a developmental comparison of judgments of length made by 5-year-olds, 8-year-olds and adults. (GO)

A total of 180 6-, 8-, and 10-year-old children participated in tasks employing an object array in which the views from the experimental positions were objectively of equal difficulty. (SB)

Perceptual counterparts of a series of conservation of length tests were presented to subjects who were categorized as conservers or nonconservers conservation of length pre-tests, and to conservers and nonconservers given conservation length training. Perceptual performance of the untrained nonconservers was significantly worse than that of the…

Data gathered on 92 girls (6-10 years of age) tested on Piagetian conservation tasks supports a theory of perceptual activity leading to decentration and indicates a change in viewing strategy associated with change in conservation status. (WY)

Investigates effects of perceptual salience and specific orientation values on 16 kindergarten and fourth-grade children executing a speeded sorting task. Kindergarten results supported the cognitive processing prediction that orientation sorting times would vary as a function of condition, but no differences were obtained for the fourth-grade…

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)

The purpose of this study was to investigate the relationship between 64 six- and seven-year-old children's perception of the reality of television and the Piagetian construct of cognitive development. The children were asked to view two television episodes (a highly similar, closely matched pair from the television series "Star Trek")…

This essay concerns the development of cognitive and perceptual skills in children from birth to the age of nine. It surveys issues, beliefs, and information about perceptual and cognitive procedures. It discusses the issues of nature-nurture, maturation-learning, continuity-discontinuity, and critical periods. It describes the development of…
