Results support view that development of part-whole perception is mediated by logiclike perceptual regulations. (MH)

Based on an M.A. thesis (Mitler) submitted to the Department of Psychology, Michigan State University, and reported in part at the meetings of the Midwest Psychological Association (Chicago, May 3, 1968).

The technique of factor analysis was used to explore the structure of five batteries of readiness tests (Gates Reading Readiness Test, Developmental Tests of Visual Perception, Metropolitan Readiness Tests, Specially Constructed Readiness Test by Olson, and Wechsler Intelligence for Children) as predictor variables for the Stanford Achievement…

Working toward a definition of a developmental model, evaluated how children (N=385) perceive their natural environment by coding their responses to words "Nature is" presented to them on a piece of paper. Results are discussed in terms of age/grade levels corresponding to characteristics of literalism, organization, and moralism. (JN)

A study was conducted to compare the relative importance of several different variables from different theoretical perspectives in explaining how children understood the advertising on commercial television. Sixty-seven first and third grade students were interviewed individually to assess their current stage of logical operations and role taking,…
