Portions of this paper were presented at the meetings of the Society for Research in Child Development, Santa Monica, California, March 1969. (MH)

Changes in children's cognitive strategies for solving simple subtractions were studied by analyzing verbal reports given immediately after each problem. The development of children's cognitive processes involved a gradual shift from more primitive and less demanding memory strategies to reconstructive memory processes to retrieval processes.…

Ten possible sources of individual and developmental differences in memory span--rehearsal, grouping, chunking, retrieval strategies, item identification, item ordering, capacity, susceptibility to interference, search rate, and output buffer--were examined in a review of the literature. Speed with which presented items can be identified emerged…

Three of the four stages of cognitive development as spelled out by J. Piaget are reviewed, and several key thinking areas which relate to the development of thinking skills in young hearing impaired children are identified. Techniques for developing such skills used at the Tucker-Maxon Oral School (Portland, Oregon) are offered. (SB)

Nine experimental conditions were partitioned into three experimental designs. A total of 576 children, drawn in equal numbers from kindergarten, second, fourth and sixth grades, memorized a 32-pair list of common nouns by the study-test recognition procedure. Among the results, in the storage phase of task performance an increasing superiority of…

Discusses Jean Piaget's information-processing model of cognitive development. (FL)

Discusses the role of the teacher in helping children to develop their intelligence. (MKM)

Briefly discusses similarities and differences between social and physical knowledge. Argues that the study of social cognition cannot be derived from, nor reduced to, the study of physical cognition, and that the social origins of knowledge need to be emphasized more in contemporary developmental theory. (Author/SS)

Picture-grouping and word-association tasks were used to evaluate the hypothesis that paradigmatic (same form class) word associates are not always categorical and may be a function of the child's understanding of interactive and categorical relations. (SB)

Piaget's conceptualization of concrete and formal operations is presented. It is contended that Piaget has obfuscated logic, metaphysics and methodology. (MS)

Three experiments investigated 14-month olds' capacity for superordinate-level inductions, using animal and vehicle domains. Found that infants did generalize properties in these domains, and that their inductions were more influenced by conceptual category than by perceptual similarity. (HTH)

Argues that causal understanding is a developmental primitive: children develop core concepts of causality at a very early age, causality plays a necessary role in subsequent development across many domains, and basic causal processes can be activated automatically or implicitly. (HTH)

Predictions about reaction times (RT) from Siegler's model were tested for the balance scale task with 6- to 22-year-olds. Regression analyses provided additional knowledge of the rules. Rule II was reformulated as a rule that always involves the encoding but not always the correct application of the distance rule. RTs provided evidence for use of…
