Study attempted to determine the viability of optimal level theory as it pertains to infant perceptual and cognitive development. (Authors)

The conservation of distance and of length and the awareness of the horizontal and of the vertical do seem to significantly precede the measurement of length, but the results did not indicate that these four tasks have any developmental order among themselves. Bibliography, charts. (Author)

The study explored ways in which congenitally blind children group objects and words, revealing their level of cognitive development. Differences in patterns of response as a function of age and type of tasks are presented, and the implications of these findings for the education of this population are discussed. (Author/CL)

Items from the Leiter International Performance Scale (LIPS) were analyzed for their conceptual versus perceptual character; these item groupings were then used to create intratest LIPS profiles for 16 language-disordered and 16 children aged 4.4 to 5.5, who were matched for CA, sex, and Leiter IQ.

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…

Investigated infants' integration of visual information across space and time. In four experiments, infants aged 12 months and 6 months viewed objects after watching light trace similar and dissimilar shapes. Infants looked longer at novel shapes, although six-month-olds did not recognize figures taking more than 10 seconds to trace. One-year-old…

Three studies looked at kindergarten, third and sixth grade students' and adults' comprehension of different types of adaptation or contrast effects for weight and temperature. Results showed improvement up to college age and revealed the importance of using older children in studies of developing theories of the mind. (SAK)

Four experiments examined the perceptual features used by 4.5- to 11.5-month olds to individuate objects involved in occlusion events. Results indicated that 4.5-month olds used shape and size features to individuate objects in occlusion events. By 7.5 months, infants used pattern, and by 11.5 months, they used color to reason about object…

Compared the recognition, perceptual saliency, and naming of color to that of other perceptual object attributes in 2- to 5-year-olds as a function of language age. Found that although color was perceptually salient relative to other visual attributes, no selective impairment to color cognition was found relative to motion, form, and size.…

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 was designed to determine the age relationships for each type of perceptual strategy used by nonconserving children during tests of conservation of quantity. The results indicate that the type of perceptual strategy reflected in children's answers varied with their age. (JMB)

Children's cognitive and perceptual development is explained in Piagetian stage theory.

This study considers recent research in human development and behavior, synthesizes commonalities across the research sources, and draws implications for art education in the classroom from kindergarten through grade 12. The research findings in cognitive development of Jean Piaget and Jerome Bruner are examined, together with other sources…
