The generality of ability factor structure in adulthood and old age was investigated. Data were analyzed for 198 young individuals (15-32 years), 156 younger old individuals (53-68 years), and 156 older old individuals (69-91). Variables were nine tests marking three ability factors. (Author/CTM)

Relative contributions of form and function information to concepts of 10 objects were investigated with first, second, and third-grade subjects. For first graders, function information about objects took precedence. For second and third graders, form information took precedence. (Author/GSK)

Presents a system for coding and analyzing dialogue involving preschool age children. Each participant assumes roles of initiator and responder and is evaluated according to different scales. Illustrates the system through recorded dialogue between mothers and their three-year-old daughters. (Author/BK)

Presents experimental findings that indicate that some number capacity is present in 22-week old infants, long before the onset of verbal counting. Suggests that verbal counting may have precursors present during infancy. (CS)

Synthesized are a number of learning theories (those of Piaget, Bruner, Gagne, Dienes and Skemp) to form one composite teaching-learning model. This model is then applied to mathematics teaching. An example is provided to illustrate how the model may be used to elaborate a teaching-learning scheme for solving quadratic equations. (Author/DS)

Presents a study that originated from a sociolinguistic research project in Mexico City during interviews with six to seven year old children from sub-proletarian groups. The study focuses on the inability of the children to distinguish between "preguntar" and "decir" ("to ask" and "to tell"). (MES)

Overviews characteristics of preoperational thought, summarizes Piaget's theory of the peroperational child's view of reality, explores implications of the preoperational stage of development for early childhood science education, and provides general guidelines for an early childhood science curriculum. (Author/RH)

The dimensions that interact during reading acquisition include properties of texts, the acquisition of reading skills and strategies, the development of cognitive and language skills, the influence of instruction, and the effects of motivational, cultural, and language variables. Discusses how these interactions may occur and describes three…

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…

Explores the relationship of an individual's reliance or nonreliance upon concrete cues in problem solving and performance on a model-based measure of hierarchical classification. Level of cognitive development, as determined by performance on Piaget-type tasks, generally predicted hierarchical classification ability of junior- and senior-high…

Investigates two levels of the spontaneous inference of thinking in others (nonrecursive and recursive) in children of ages 10, 12, 14 and 16 using a person description task. (Author/SS)

Investigates the hypothesis that those individuals who have not reached their full potential in moral reasoning given the limits set by their stage of Piagetian development would advance significantly more than those who have reached their potential in response to a moral education program. (Author/SS)

Finds that the object concept scores of 104 infants were relatively independent of IQ and background variables, showing that object concept is the most stable developing function in infants and an accurate reflection of infant cognitive potential. (RL)

Support claims that the "Defining Issues Test" of cognitive-moral development cannot be faked higher. Finds that instruction about cognitive-moral development affected the scores of the teacher trainees who were tested. (RL)

Suggests that the same developmental trend of fears that appears in normal children appears in the retarded, and that these fears follow Piagetian theory, proceeding from egocentric perceptions of causality to realistic cause, and effect thinking. (RL)
