The present study was a causality study that investigate the effects of conditional factors; if x, y & z are the independent factors (e.g. socio-economic status, Anthropometric status, and home environmental status) on the dependent factors (e.g. memory, social skill, language acquisition, logical reasoning, and problem solving). The present…

Children, aged 4-8 were given 2-term relational problems to test the hypothesis that only older children can process sentences as propositions and realize their logical implications. Results indicated even the youngest children could perform the task. (ST)

These forty conference papers deal with a wide variety of new approaches to the application of developmental theory. The papers represent a cross-section of current research methodology and techniques used to evaluate such traditional Piagetian topics as concrete and formal operations, conservation, classification skills, language development,…

Evidence is provided to refute the suggestion, made by Macnamara et al. (1976), that four-year-old children perform logical operations corresponding to formal logic upon the sentential components of implicative verbs to produce indirect implications. It is argued that children use past knowledge plus additional premises to derive indirect…

Presents a rebuttal to Hidi and Hildyard's (1976) criticism of Macnamara et al.'s (1976) assertion regarding the ability of four-year-old children to grasp implicatives and presuppositions. (AM)

The educational implications of Piaget's concept of intelligence provide a framework for the application of theory to educational practice. The uniqueness of individual learning is compared to stage-based teaching. Social interaction is viewed as one of the major forces in cognitive development. (JN)

Finds that various aspects of formal reasoning correlated significantly with mean t-unit lengths written by high school freshman boys, but not by freshman girls. Suggests that the reasoning tasks may have been biased against females. (RL)

The study examined the relation of language use and logical thought to social experience with both age and class held constant. The primary assumptions under study were: that the logic of symbolic grouping was highly sensitive to a child's experience with the objects to which that logic was applied; that the existence of diglossia in a bilingual…
