Describes Jean Piaget's transformation of society's conception of childhood thought. Emphasizes the enduring contribution to developmental psychology of Piaget's constructivism, his description of developmental mechanisms, his cognitivism, his explication of structural and functional analysis, and his addressing of epistemological issues and…

Three experiments tested four- to seven-year olds' ability to understand and reconcile message-desire discrepant stories. The findings suggest that young children can refrain from a performative response and, as a consequence, attend to literal meaning under some conditions when evaluating utterances. (MDM)

Briefly summarizes Vygotsky's life, the appeal and subsequent abandonment of his ideas in the 1960s, and renewal of interest in the 1970s and 1980s (often at the expense of Piaget). Praises van der Veer and Valsinger's book as a realistic picture of Vygotsky's background, life, and work, of the scientific and political context in Russia and of his…

Three studies involving eighth through twelfth graders examined the role of relativistic thinking in the cognitive, social, and emotional lives of adolescents. Findings indicate that adolescents appreciate the relativistic character of the knowing process and that there is a close relationship between epistemic attitude and identity status. (SH)

Describes laboratory research on REM (rapid eye movement) sleep in children ages five to eight. Image quality, self-representation, and narrative complexity of dreams all develop as age progresses. Children's representational intelligence predicts their rate of dream production, but language skills do not. (GH)

Argues that saying that students have "thinking problems" is hardly a useful diagnostic statement or even a sensible description of flawed cognitive development. Maintains that what is needed to encourage students to think are some sensible models and attractive opportunities to do it in contexts that matter to them. (RS)

Addresses the question of whether the social studies should be abandoned. Discusses Kieran Egan's analysis of the importance of storytelling and Egan's proposal to abandon the social studies curriculum in favor of a pedagogy more consistent with the way children think. Critiques Egan's view and examines implications for educators. (SG)

Preschoolers made judgments about solutions in which substances were dissolved. Preschoolers (1) distinguished visual appearance from underlying reality; (2) recognized the conservation of taste, smell, and dangerous properties; and (3) by age five recognized that matter can be decomposed into pieces too tiny to be seen by the naked eye. (BC)

Describes 4 experiments examining 10-month-old infants' causal event perception. Results from all experiments indicated that infants perceived causality of simple events by associating a specific agent with a causal action. These results provide more support for an information-processing view of causal perception than for a view that explains…

Discusses how research in the developmental cognitive neurosciences can contribute to an understanding of the complex relations between various aspects of naming and reading processes. Reviews findings from both neuropsychological and reading research on letter-naming and general naming speed, and analyzes the methodological differences between…

Two studies showed that children of about four years of age had begun to understand that beliefs may be held with differing degrees of certainty. This understanding was tied to the children's understanding of the nature of beliefs and the distinction between appearance and reality. (PCB)

Reveals that during the elementary school years, children acquire a firm understanding of the brain as the primary locus of psychological attributes and identity. The early school years, when children are five to seven years old, appear to be a transitional phase, when performance is variable and subject to task conditions. (RH)

Tested adults and children (age 6 to 16 years) on 4 speeded tasks that included 19 experimental conditions. The 6- to 16-year olds' response times decreased with age as a function of adults' response times. (MM)

Suggests that in learning and development, the process of comparison can act as a bridge between similarity-based and rule-based processing. A structure-sensitive comparison process, triggered by experiential or symbolic juxtapositions can: (1) facilitate understanding of structural commonalities and the abstraction of rules; and (2) facilitate…

Investigated what makes young children acknowledge a false belief held by another person. Showed movies in which a stereotypical item in a familiar box was replaced by one character with an atypical item. Found highly significant improvement in preschoolers' acknowledgment of second character's false belief when preschoolers saw stereotypical…
