The purpose of this study is to analyse geometric transformations of children in the early childhood period. The study utilised a case study to design one of the qualitative research methods. Interviews were conducted with 6-, 7- and 8-year-old children, in total 24 children, who were enrolled in a private pre-school and a primary school of the…

The processing of a transitivity task by 7-, 9-, 11-, and 13-year-old learning disabled children was studied. All Ss, regardless of age, received highest scores on tasks involving linguistic input. There was no evidence of a developmental shift from spatial into linguistic reasoning. (Author/SEW)

Goals and challenges pertaining to infant sensory and perceptual development are discussed. It is suggested that the inability of researchers to think and talk wisely about "partial accomplishments" in development creates a barrier in developmental research. Conceptual schemes are needed to accommodate these partial accomplishments. Three major…

English-speaking and Dutch-speaking children were asked to pick the big, tall, or long members of pairs of bricks. Comprehension improved with age but older children in both groups were prone to choose the taller (but smaller) of two objects when asked to point to the bigger one. (SED)

In this study of sensitivity to viewpoint, children between the ages of 6 and 14 years were asked to draw an L-shaped array of 3 cubes from 1 of 3 views. At every age, children showed sensitivity to their view in the sense that there were consistent differences between the drawings produced in the three viewing conditions. (SH)

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…

Tests seven- , 10- , and 13-year-olds for developmental differences in processes and strategies involved in geometric matrix solution and the relationship between strategy differences and item complexity. (AS)

In the past 25 years, there has been an explosion in research on the development of perception. The research has produced discoveries at multiple levels: ecological analyses, models of representation and process, and improved understanding of biological mechanisms. This book provides a comprehensive treatment of infant perception, bringing…
