We show that the neurological condition of synaesthesia--which causes fundamental differences in perception and cognition throughout a lifetime--is significantly represented within the childhood population, and that it manifests behavioural markers as young as age 6 years. Synaesthesia gives rise to a merging of cognitive and/or sensory functions…

Kim (1985) found that both English-speaking and Korean-speaking children find true negative sentences more difficult to verify than false negative sentences. A closer examination of the findings reveals that the difficulty is greater among Korean-speaking children. (Author/RH)

Replies to Akiyama's critique, pointing out areas of agreement between the Kim and Akiyama studies and areas of disagreement. Concludes that, contrary to Akiyama's argument, the Kim (1985) data would not directly challenge the cognition primacy hypothesis in any serious manner. (RH)

A path model of genetic and family environmental transmission was fitted to published twin correlations and to general cognitive ability data from adoptive and nonadoptive families in which children were tested yearly through the fourth year. Longitudinal genetic correlations from infancy to adulthood were modeled explicitly, as were effects of…

Compares the Genevan and Cattell-Horn theories of intelligence and describes both similarities and differences. Describes a study investigating the relation of the Piagetian operative level to the child's ability to use crystallized solution procedures (aids) in making elementary numerical comparisons. (HOD)

This paper discusses a model of information storage and retrieval, the k-d tree (Bentley, 1975), a binary, hierarchical tree with multiple associate terms, which has been explored in computer research, and it is suggested that this model could be useful for describing human cognition. Included are two models of human long-term memory--networks and…

Presents results from an Australian study examining whether children who use cognitive strategies in solving simple addition questions develop greater proficiency in addition than children who do not use such strategies. Describes the subjects, instruments, procedure, and instructional treatment. Concludes that the development of cognitive…

The study found that eight specifically language-impaired children (ages four and five) were more limited than eight normally developing children (ages two and three, matched for mean utterance length) in the use of both subject case marking and verb morphology. A relationship between the two types of usage was found in both groups of children.…

An exploratory study of structured and unstructured play was conducted with a small number of severely disturbed and normal children 9 to 13 years of age. Specifically, the investigators characterized psychopathology from a cognitive-developmental perspective by focusing on the Piagetian "scheme" and its manifestation in the play and…

The purpose of this study was to determine how children at different ages understand the concept of temperature, examining particularly the logicomathematical aspects of the concept. In doing so, three developmental approaches were compared: (1) Piaget's structuralist approach; (2) Siegler's rule assessment approach; and (3) Anderson and…

Although much has been written about the ineffectiveness of schools in imparting cognitive skills, there is little reliable knowledge by which to judge such claims. While the typical school effectiveness study focuses on variation in educational outcomes between organizational units, there have been few studies which compared "school"…

This discussion first analyzes major claims of a cognitive-developmentalist perspective on the use of microcomputers in early childhood education. Five topics are specifically addressed: microcomputers and intellectual structures, microcomputers as cultural events, microcomputers and strategy repetoires, instruction and the self-construction of…

Observed a group of 46 children classified at 20 months as either behaviorally inhibited or uninhibited, and 18 children who were classified aa falling at neither extreme at 5.5 years of age, in contexts designed to evaluate behavior in social situations and heart rate, heart variability, and pupillary dilation to cognitive tasks. (HOD)

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)

Reviews studies of cognitive development of high school students in small rural schools. Finds that while research clearly shows that students in small rural schools may not be as intellectually developed as students in large schools, little research has been done to identify possible causes for this difference.
