This review begins with a brief history from Piagetian perspective-taking development, through metacognitive development, and into the past and present field of theory-of-mind development. This field has included research on what infants and children know about a variety of mental states, on possible causes and consequences of mentalistic…

Tested the hypothesis that understanding of the pretend-real distinction develops earlier than understanding of the theoretically related apparent-real distinction. Found 3-year-old children consistently performed better on pretend-real tasks than on apparent-real tasks, even when the tasks were identical except for the distinction tested. (SKC)

If human cognitive development advances through a series of broad and general stages, then the child's mind at any developmental point should seem consistent and similar across situations in its maturity level and general style. However, there appear to be factors and conditions that promote homogeneity and heterogeneity in the child's cognitive…

Reports on the results of three studies that investigated whether three- and four-year olds interpret television images as mere pictorial representations of objects or as real physically present objects. Children's developmental differences are discussed, and a developmental sequence of understanding television reality is presented. (28…

Summarizes recent research which attempted to discover what children of different ages know about the appearance-reality distinction and related phenomena. Findings show that what helps children grasp the distinction is an increased cognizance of the fact that people are sentient subjects who have mental representations of objects and events. (PS)

Summarizes researchers' beliefs about cognitive development. Topics include (1) the child as constructive thinker; (2) new research methods; (3) the characterization of children's cognitive development; (4) estimates of children's competence; (5) stages of development; (6) interrelations among developmental skills; (7) mechanisms of development;…

This paper describes two experiments in which children in grades 1, 3, and 5 were given three kinds of spatial perspective-taking problems to solve as quickly as they could: (1) C problems, solvable only by computation (that is, noting which features of a particular object array were closest to another observer in order to estimate how the array…

Reports seven studies of the acquisition of knowledge about the appearance-reality distinction and suggests some conclusions about the course of conceptual development in this area from early childhood (3 years) to adulthood. (Author/NH)
