Based on a prior model on modularity of the brain, a new modular model of intrapersonal communication was developed which focuses on brain processing, encompassing both the structures and the functions of those structures in the creation of messages. The modular mind is a bio-social model of communication which presupposes a relationship between…

Applies the analytic technique of maximum likelihood factor analysis to the intercorrelations of the Wechsler Intelligence Scale for Children-Revised's subtests as a means for assessing more or less differentiation and integration. (HOD)

Examined three- to four-month-old infants' ability to form perceptually based categorical representation in the domains of natural kinds and artifacts. By showing the availability of perceptually driven basic and superordinate-like representations in early infancy that closely correspond to adult conceptual categories, findings underscored the…

Two experiments investigated perceptual primacy of dimensional and similarity relations in stimulus classification of mentally retarded children. Results support a distinction between separable and integral stimulus structures, but do not support an integral-to-separable shift in perceptual development. Results suggest implications for…

Describes two studies investigating the development of recursive thinking in 60 Dutch children five, seven, and nine years of age. The first study replicated earlier research employing a verbal production procedure. The second study used verbal comprehension procedures and concluded that development appears two years earlier than indicated by the…

Tested children with apparatus that dropped balls through clear or opaque interwoven tubes. Found that older children could solve configurations with greater number of tubes than younger children. Success with clear tubes did not transfer to opaque tubes. Significantly, errors were consistently directed to location directly below ball's last seen…

Spatial aptitude tests designed for elementary school children were given to third-grade students from both suburban and rural schools in Pennsylvania. Results were scrutinized by the declared favorite subjects of the participants and organized by gender. Students who preferred science and mathematics did better on spatial tests than students who…

Examined perception of object unity in partial occlusion in 72 infants. Recorded how long subjects looked at a display of complete and incomplete rods. In test and control conditions, infants looked longer at broken rods than at complete rods, suggesting that infants' cognitive, visual, or attentional skills may be insufficient to support…
