This research tests whether analogical learning is present before language comprehension. Three-month-old infants were habituated to a series of analogous pairs, instantiating either the "same" relation (e.g., AA, BB, etc.) or the "different" relation (e.g., AB, CD, etc.), and then tested with further exemplars of the…

Young children have been taught simple sequences of alternating shapes and colors, referred to as "patterning", for the past half century in the hope that their understanding of pre-algebra and their mathematics achievement would be improved. The evidence that such patterning instruction actually improves children's academic achievement…

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…

A propositional logic game which is a subtest of the new British intelligence scale was analyzed to determine the extent to which skills proper to a single Piagetian period, formal operations, were hierarchically ordered. Item response patterns from 60 14-year-olds were categorized by means of ordering theory, a boolean algebraic measurement…

Kindergarten children were administered tests of inductive reasoning and field dependence and a series of perceptual egocentrism tasks. Results confirm a positive relation between field dependence and perceptual egocentrism; they also question the validity of the field-dependence construct in early childhood. (GO)

This study assessed the influence of age and ability on linear syllogistic reasoning in early adolescence by presenting bright and average 11- and 13-year-olds with 64, 3-term series problems. Results showed a dramatic effect on performance due to ability. Age effect was only marginally significant. (JMB)

This study is based on an earlier investigation by Brant and Trabasso, in which it was demonstrated that 4-year-old children could perform transitive inferences when training forced information encoding by involving questions about two comparative dimensions of an object (long and short). The present study was designed to examine the sources of…

A study investigating developmental differences in the ability to reason with conditional propositions used five variations of Wason's selection task to assess conditional reasoning in 132 eighth, tenth, and twelfth grade adolescents. In addition to examining developmental differences, the study had as an objective to examine the role of semantic…

Used single-subject analyses to examine the developmental difficulty of the ulterior motive question (the backward inverse inference) in five- and seven-year-olds. Results suggest that children's difficulties with ulterior motive information result both from the abstract nature and the logical form of the task. (Author/SKC)

Three paper-and-pencil formal operations tests were administered to groups of eighth graders and adults. These measures provided scores that indicated each subject's level of reasoning for three second-order operations: combinations, proportionality, and propositional logic. (JMB)

Based on a set of theoretical assumptions relating to the cognitive modificability of low functioning adolescents, a program of Instrumental Enrichment was developed and implemented with 41 hearing impaired secondary students. The primary goals of Instrumental Enrichment included: (1) improving performance in spatial relations, (2) improving…

Preference scores were determined for several different groups of students ranging in age from seven to adult. In addition, instruments were administered to determine the cognitive level at which the students were capable of functioning. Comparisons between the students' cognitive level and preferences were made. The results indicated that the…

This study investigated the use of covariation as a principle of causal analysis in children 3-4, 6-7, and 9-11 years of age. The results indicated that children as young as 3 years were capable of using covariation information in their attributions of simple physical effects. (Author/CS)

Piaget's theory of cognitive developmental levels is criticized on the grounds that it blends empirical and philosophical issues of knowledge and, therefore, confuses genetic psychology and epistemology. (JN)
