Rudolf Arnheim, former Harvard Professor of the Psychology of Art, developed a theory that the perception of the structure of things in the world is based on simultaneous use of two primary systems: (1) the cosmic system of concentricity and (2) the parochial system of the Cartesian grid. The Cartesin grid imposes order, while the concentric…

The relationships between perception and conservation of length were investigated in a developmental comparison of judgments of length made by 5-year-olds, 8-year-olds and adults. (GO)

Portions of this paper were read as part of a symposium on The Meaning of Smiling and Vocalizing in Infancy'' at the 1970 meeting of the American Psychological Association, Miami Beach, Florida, September, 1970. (Editor)

In contrast to earlier notions, a systems view of an organism's development sees genes as only one component in a hierarchy of influences that produces finished traits and differentiation. Developmental canalization proceeds from genes, behavior, and environment as well as from the coaction of these factors. (BC)

Piaget's theory of space perception is presented in the format of a hypothetico-deductive system. Eleven hypotheses regarding infants' space perception are defined, and Piaget's evidence for each is summarized. Presuppositions underlying the arguments are explicated. Critical notes are inserted and general conclusions are briefly discussed.…

A child whose behavior reflects only perception of a stimulus and reaction to it is considered more perceptually bound than an adult whose behavior is also directed by theories, values, and ideas. Based on this analysis three testable hypotheses emrege: (1) stimulus complexity is a better predictor of attention for the more perceptually bound, (2)…

Twenty infants, 12 weeks of age, were subjects in an experiment to test the effects of maternal behavior on their perceptual-cognitive development. Each mother and child were observed in a controlled naturalistic setting, every 10 seconds their various behaviors were recorded, and then the mother was interviewed. During an experimental session the…

Program planning for economically deprived children might be improved if behavioral information pertinent to specific subcultural groups were systematically obtained. This prospectus focuses on developing a three-part behavioral model which, when integrated, would identify and profile the nature of disadvantagement in terms idiosyncratic and…
