An important aspect of perspective-taking ability is the appreciation that mental states such as beliefs, desires, and knowledge change over time. The current study focused specifically on 3-, 4-, and 5-year-olds' understanding that they will have knowledge in the future that they do not currently possess--for example, that when they are…

The relations among various spatial and mathematics skills were assessed in a cross-sectional study of 854 children from kindergarten, third, and sixth grades (i.e., 5 to 13 years of age). Children completed a battery of spatial mathematics tests and their scores were submitted to exploratory factor analyses both within and across domains. In the…

Classic theories of self-development suggest people define themselves in part through internalized perceptions of other people's beliefs about them, known as reflected self-appraisals. This study uses functional magnetic resonance imaging to compare the neural correlates of direct and reflected self-appraisals in adolescence (N = 12, ages 11-14…

Patterns of development of ToM belief abilities in intellectually disabled (ID) children and typically developing (TD) children matched on their developmental age were investigated. The links between cognition, language, social understanding and ToM belief abilities were examined. EDEI-R [Perron-Borelli M. (1996). "Echelles Differentielles…

In comprehending stories, adults create mental models from which they follow the actions of the characters from the characters' different mental vantage points. Using a novel methodology, this study is the first to examine when children attain the narrative ability to track the mental perspective of characters. That is, when do children follow…

Investigated relationship between young children's ability to predict another observer's interpretation of an ambiguous picture and to identify the source of a misinterpretation after it had occurred. Found that six-year-olds were more likely than four- and five-year-olds to predict that a puppet would misinterpret the target-restricted view and…

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)

Results support the hypothesis that certain classification skills underlie two types of role-taking ability: (1) in which children were asked how another child would think a cartoon ended if shown only the beginning; and (2) in which children were asked how another child would think a cartoon began if shown only the end. (Author/DB)

Investigates two levels of the spontaneous inference of thinking in others (nonrecursive and recursive) in children of ages 10, 12, 14 and 16 using a person description task. (Author/SS)

This study examined how 21 blind children (ages 3-8) performed perspective-taking tasks compared to 60 sighted children with and without blindfolds, under different conditions of distance and barriers. Results showed that, with increasing age, young blind children did not exhibit a significant increase in accurate perspective taking. (JDD)

In four experiments, three, four, and five year olds were successful in solving perspective-taking problems when they were asked what object occupied a specified location with respect to a hypothetical observer. Results indicated developmental change in several important aspects of spatial performance. (BC)

This study assessed social perspective taking in 57 children classified as educable mentally retarded divided into 3 age groups from 8-16 years. Significant differences in social perspective taking were obtained between the three groups in understanding individuals and between the older and two younger groups in understanding friendship.…

Describes the development of cognitive structure in adolescence as establishing isomorphism between subject and environment. Identifies two dimensions of stages in the development of individuals'"work structure," i.e., the network of relations existing between the individual and his work.
