A total of eighty 9-month-old infants were presented with a problem consisting of several different conditions which separated response, position on a table, and absolute spatial position as factors leading to errors in search for hidden objects. (MS)

The major results partially confirm the hypothesis of a reciprocal relationship between the experience of learning to read and the cognitive-linguistic skills which undergo development between the ages of five and seven. (RC)

A sample of 108 eight-grade students using Intermediate Science Curriculum Study (ISCS) were tested with four Piagetian tasks: two tasks were related to ISCS concepts, two were not. Concludes that no students were formal operational, most were concrete operational, and most performed better on the non-ISCS related tasks. (MLH)

Presents a descriptive analogy comparing Piaget's theory of intellectual development to the development of athletic abilities in order to provide insight into Piagetian theory. (SL)

Approximately 200 children, age 5-11, from three different regions in Southern England were interviewed about their understanding of social events: school, store, money, payment, the community and government, some specific jobs and acquisition of a role. (MS)

An overt rehearsal procedure was used to study the relationship between 48 third- and 48 sixth-grade children's rehearsal strategies and their memory performance under difficult conditions of test expectation. This study addressed the question of why active rehearsal content results in superior recall performances. (MS)

The results of this study provide evidence that schools reduce the variance of learned cognitive skills among children. (MM)

Two studies examined short- and long-term effects of phonological awareness training on reading and spelling of German kindergartners. Found no long-term effects on reading and spelling skills beyond first year of elementary school. Determined that training affected phonological awareness skills but not phonological processing, letter knowledge,…

Used path analysis in two experiments to examine possibility that age difference in infants' long-term retention were artifacts of correlated differences in learning rates or learning opportunities. Found that developmental declines in forgetting rates between 12 and 18 months were independent of developmental differences in learning. Age…

Uses results of laboratory and natural language analyses of 2- to 4-year olds' explanations of human behavior to argue for a theory-type view of biological, psychological, and physical domains of thought. Concludes that children as young as 2 years show three different reasoning systems in their explanations of everyday phenomena, especially human…

Examined reasoning in normal, autistic, and deaf individuals. Found that deaf individuals who grow up in hearing homes without fluent signers show selective impairments in theory of mind similar to those of autistic individuals. Results suggest that conversational differences in the language children hear accounts for distinctive patterns of…

Elementary school children were interviewed about how gears move on a gearboard and how they work in commonplace machines. Children's reasoning became more general, formal, and mathematical as problem complexity increased, suggesting that mathematical forms of reason may develop when they provide a clear advantage over simple causal…
