This article elucidates the unfolding of 3 phases of cognitive development through which typical children move during the first 2 years of life to illuminate the interrelationships among early cognition, communicative intention, and word-learning strategies. The resulting theoretical framework makes clear the developmental prerequisites for social…

This report summarizes research about development during the first 3 years of life. It highlights research in domains that are foundational for later school readiness and success, including: (1) perceptual, motor, and physical development; (2) social and emotional development; (3) approaches to learning; (4) language and communication; and (5)…

Children's understanding of the cardinal significance of counting is often assessed by the "give x" task, in which they are categorized as "counters" or "grabbers". Previous research indicates a sudden stage-like shift, implying insight into a principle. Employing a microgenetic approach, the present study was…

Investigated whether and how children age 5 to 7 employed counting to measure and integrate the duration of two events, which were accompanied by metronome beats for half the children. The rhythm enhanced use of counting in younger children. By age 7, most counted spontaneously, using sensible counting strategies. (SKC)

Responds that questions of study by Kuhn and others (PS 524 345) in this issue were motivated by concerns about the role of scientific thinking in general thinking, not in development of scientific reasoning. Study was meant to increase understanding of role of strategies in development, not provide definitive explanation of how strategies fit…

This study tested three hypothesized mechanisms through which explanations might facilitate problem-solving strategy generalization in kindergarteners through second graders. Results suggested that explanations facilitated generalization through the creation of novel goal structures that enabled children to persist in use of the new strategy…

Used a microgenetic method to examine knowledge acquisition as a process by coordinating existing theories with new evidence. Subjects were 17 community college students (ages 22-47) and 15 fourth graders. Assessed knowledge acquisition in problem solving in both physical and social domains. Found multiple strategies for, and varying levels of,…

Explores the nature, importance, and development of child metacognition, arguing for the assisted development of metacognitive awareness in young children. Identifies factors that enhance metacognitive development and thus assist the transfer of learning. Suggests that metateaching strategies can help mediate the metacognitive strategies of…

Two experiments examined impact of training in false belief understanding on 3-year-olds. Training involved encouragement of reflection on the event of various false belief scenarios, especially the protagonist's thoughts. Results suggested that task-specific strategies for close transfer posttest success were learned, rather than demonstrating a…

Investigated understanding and use of numerals in 48 children ages 3 and 4. Found that children rarely noticed the absence of numbers if they were not able to explain their purpose. They used several methods to represent number on notes for the milkman, party invitations, and labels. Results suggest that understanding preceded use of numerals.…

When taught to link sorting to self-instruction ("I'm looking for blue triangles") children show perfect accuracy in sorting. This study investigated if this performance would generalize to new stimuli. One participant showed near-perfect generalization to all new stimulus sets (shapes, letters, pictures); two had difficulty with…

Focuses on the strategies young children (N=115) use to solve rectangular covering tasks before they have been taught area measurement. Children's solution strategies were classified into five developmental levels. Emphasizes the importance of understanding the relationship between the size of a unit and the dimensions of the rectangle in learning…

Describes a study that compared the effects of microworld microcomputer training and real world training on sorting behaviors of 2- and 3-year-olds. Discussion of the relationship between cognitive development and the ability to process microworld training focuses on different reactions between the two age groups. (42 references) (CLB)

Extends and replicates the 1948 Soviet study by Istomina that examined the age at which children use deliberate strategies to aid recall and the effect that task context has on remembering. Subjects were 3- to 7-year-old children. Istomina's results were not replicated in this study. (HOD)

Tested 32 4-year-olds and 32 6-year-olds for free and cued recall following either play-and-remember or sort-and-remember instructions and assessed them for their metamemory of the efficacy of conceptual and perceptual sorting strategies. Younger children recalled more items under sort-and-remember, whereas no recall differences were found for the…
