This study investigates the relationships of domain-general cognitive abilities and domain-specific verbal and mathematical abilities to students' educational characteristics when two theoretically grounded, but competing structural models are applied. In the standard model, a single latent ability causes interindividual differences in the…

A 2-part investigation was conducted to examine the ways children resolve the inherent ambiguity of spatial descriptions in terms of cues indicated by the three constituents of spatial propositions: predicate, referent, and relatum. In the first study, it was hypothesized that certain objects, structural markers, and definite articles accompanying…

Explores longstanding inconsistencies in Piaget's account of development of spatial representation and perspective-taking. Examines Piaget's early writings and the findings of the original "three mountains" experiment. Concludes that Piaget's alternative theory is compatible with contemporary thinking and is important as a contributory…

Examines the ability of six- and eight-year-old children to hide and recover 20 marbles in a large room containing 100 possible sites. Shows that children tend to concentrate activities in sections of the room and are sensitive to clusters of proximal sites. (HOD)

To learn about teachers' conceptualization of memory strategy use, memory knowledge, and developmental changes in these skills, investigators administered a questionnaire to 59 teachers of children in kindergarten through sixth grades. The questionnaire included sections on strategy use, metamemory skills, and memory monitoring and control…

Second and third graders and fifth and sixth graders were tested in a very large, unfamiliar environment to determine the relation of their knowledge of an abstract reference frame to performance on a spatial inference task. (HOD)

Examines the fallacies about the nature of abilities and learning and about the interaction between sense modalities which follow from the dichotomy in relation to explanations of spatial development in the blind. Suggests that interactions between cognitive and perceptual factors need to be considered to explain more adequately effects of sensory…

This study investigated the speed of encoding and rotation of images during simple spatial rotational operations to discover any similarities or differences in groups of differing spatial ability. This project was subdivided into five basic subproblems. First, research was done to arrive at a simple, easily testable information processing model…

Compared 12 right-handed adolescent females with a history of idiopathic precocious puberty to 12 closely pair-matched normal controls of similar maturational status to test the association of physical maturation with cognitive abilities and the mediation of this association by hemispheric specialization. (HOD)

First and fifth graders participated in this assessment of ways in which differential experience with objects in a spatial array might establish relative landmarks within the array. Results suggest that different levels of experience can establish elements as relative landmarks in spatial memory. (Author/RWB)

Examined the development of pattern recognition in infant pigtailed macaques using the familiarization novelty technique. Results indicate that by at least 200 days postconception subjects show a consistently reliable visual response to novelty. (Author/RH)

A sample of 44 infants of five months of age showed a significant reaching preference for the apparently nearer region of a computer-generated display. This indicated that the infants were sensitive to boundary flow information for depth at an edge. (RH)

Spatial matching--the ability to distribute search effort in accord with the distribution of hidden resources--was studied in 18- to 54-month-old children. The principal development was the appropriate use of win-shift response. (Author/RWB)

Reports on an exploratory study of a metacognitive approach to teaching low achieving secondary students. Asserts that the research team hoped to examine a process whereby a dialog about learning processes would develop. Finds that all students indicated that they were able to focus on learning as a topic of conversation. (CFR)

Concepts important to cognitive development in children can be classified according to several levels. At level 1, concepts are equivalent in structural complexity to binary relations and univariate functions. At level 2, concepts are equivalent to compositions of binary relations, binary operations, and bivariate functions. At level 3, concepts…
