Two books relating to Piaget's theory of intellectual development are reviewed. (DB)

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)

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…

Investigates the development of the appearance-reality distinction in 24 children of 5 years, 24 undergraduates, and 12 adults. Results suggest that there is a transitional period in the development of the distinction that begins around age 5 years. (RJC)

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…

Holds that young children are limited in their knowledge about cognitive phenomena ("metacognition") and do relatively little monitoring of their own memory, comprehension, and other cognitive enterprises. Proposes a model addressing the question of what adult-like knowledge and behavior might constitute metacognitive developmental targets toward…

Examines the ability to differentiate appearance-reality and Level Two perspective-taking in tactile modality among a total of 92 children aged two-four years in three studies. The results indicate that three-year-olds find tactile appearance-reality and Level Two perspective-taking tasks easier than visual ones. (RJC)

Interviewed 5-, 6-, 7-, 8-, and 10-year olds, and adults regarding their knowledge about primary-consciousness, reflective-consciousness, and control activities. Found that the recognition that people do not engage in conscious mental activities when unconscious is still developing during the late middle-childhood years. (Author/KB)

Two studies tested three year olds' understanding of five mental states in a false belief scenario. Results indicated that children understand that desires can differ from reality before they understand that beliefs can. Results concerning children's understanding of pretenses, and dreams that differ from reality are discussed. (BC)

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;…

The author considers memory as being composed of four categories. The fourth category--metamemory--refers to the individual's knowledge and awareness of memory or of anything pertinent to information storage and retrieval. It is that aspect of memory that deals with the how and what of memory itself. The paper first presents a model of what could…

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…

Sixty young children were tested for their understanding that a person who is mentally focused on one thing devotes little or no simultaneous attention to another, totally irrelevant thing. Though most 6- and 8-year olds demonstrated an understanding that task-oriented thought and attention were selectively focused, most of the 4-year olds showed…

Three studies compared 3-year-olds' ability to attribute fact beliefs and value beliefs to another person when these beliefs differed from the children's. Value beliefs concerned the tastes and smells of substances, and whether stimuli were pretty or not. Numbers of subjects involved in the three studies were 32, 16, and 20. The consistent finding…

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)
