Evidence suggests that visual processing is divided into the dorsal ("how") and ventral ("what") streams. We examined the normal development of these streams and their breakdown under neurological deficit by comparing performance of normally developing children and Williams syndrome individuals on two tasks: a visually guided action ("how") task,…

The most common behavioral technique used to study infant perception, cognition, language, and social development is some variant of looking time. Since its inception as a reliable method in the late 1950s, a tremendous increase in knowledge about infant competencies has been gained by inferences made from measures of looking time. Here we examine…

When entering the Blind Childrens Center (BCC), what a person might not realize is that four of the five visually impaired children in a classroom share the same diagnosis of Optic Nerve Hypoplasia (OHN). ONH is the leading cause of blindness and visual impairment in young children. It is important that these children participate in an inclusive…

Rule use in perceptual classification was investigated in adults and in 4- to 12-year-old children. Two studies of performance on triad classification tasks with large samples (N=226 and N=328) are presented to (a) contrast theoretical predictions from the holistic-to-analytic-shift theory (Smith & Kemler, 1977) and the differential-sensitivity…

During the second year of life, infants exhibit a "video deficit effect." That is, they learn significantly less from a televised demonstration than they learn from a live demonstration. We predicted that repeated exposure to televised demonstrations would increase imitation from television, thereby reducing the video deficit effect. Independent…

Most international adoptees (IA) have rapid catch-up of the delays common at arrival. However, it is not known whether development at arrival predicts later abilities or school readiness. Therefore, we comprehensively evaluated language, fine motor, visual reception (VR), executive function (EF), attention (ATT), and sensory skills (SS) in IA…

This study examined changes in rhythmic arm shaking and laterality biases in infants observed longitudinally at three points: just prior to, at, and just following reduplicated babble onset. Infants (ranging in age from 4 to 9 months at babble onset) were videotaped at home as they played with two visually identical audible and silent rattles…

The author believes that creativity and intelligence in children develop only minimally according to a built-in pace but depend mainly on having the opportunities to develop. (AN)

Though increasing complexity increased the difficulty of discrimination of form, nursery school, kindergarten, and first grade children were all above chance in performance, older children being superior. The results are discussed in relation to developmental perceptual theory. Portions of this paper were presented at the American Psychological…

Describes the perception-action approach and the dynamic systems approach to motor development. Discusses the importance of understanding the development of the brain and the importance of longitudinal studies of motor development. (RJC)

Investigates the knowledge of thematic and taxonomic relations of 15 children of 26 months and 24 children of 34 months. Both age groups were able to identify thematic matches. However, 34-month-olds were able to recognize a wider range of thematic associations than 26-month-olds. (RJC)

Discusses C. Milbrath's thesis that artistically talented and less talented children follow different developmental paths because they rely on different ways of responding to the world. Relates this thesis to studies of the childhood work of Paul Klee, Henri Toulouse Lautrec, and Pablo Picasso. (SLD)

Traditional developmental protocols based on neurological or sensorimotor models frequently underestimate the cognitive status of physically handicapped infants. A critical review of current clinical practices in the area of infant assessment is followed by a discussion of an alternative approach, a perceptual-cognitive approach, and the…
