Data obtained under naturalistic conditions do not support the notion of a close fit between the growth of geometric concepts during the concrete operational period and "realism" in art. Realism here refers to the ability to portray the objective proportions of a figure, to coordinate spatial relations and distances, and to represent a…

Attempts to specify whether previously reported limitations on young children's full-report capacity lay in a smaller amount of available information, in a shorter trace duration of information in visual information storage (VIS), or in poorer coding of information into permanent storage.

This study sought to assess the ontogenetic course of three classes of size-value phenomena. Size-value phenomena refers to the observation that valued and neutral objects physically equal in size are judged as unequal. Results are discussed in terms of perceptual development. (ST)

Children three through six years of age were asked to imitate actions depicted in photographs to determine whether they could interpret information of action in photographs. Twenty children at each of four age levels, 3, 4, 5, and 6 years, were asked to imitate two photos, each showing a young child performing a physical action. Following this…

A brief summary of research findings which support the hypothesis of scriptal knowledge structures in children and which indicates that children use such structures in ways very similar to those of adults is provided in this paper. Research reveals that when children as young as three are asked to tell what they know about events, they tend to…

This paper describes three studies designed to determine whether there are age-related differences in children's memory for implicit and explicit information in prose. In the first study, six experimental paragraphs were read individually to a total of 60 children in grades K-5. Each child was then asked four verbatim recall questions (specific…

The generalization of acquired competencies, specifically flexibility of closure, was the subject of this research. Flexibility of closure was defined as the ability to demonstrate selective attention to a specified set of elements when presented within various settings (the larger the number of settings from which the desired set of elements can…

To determine whether children possess representations and concepts of space before they acquire verbal descriptions of these, children's formation of symbolic representations of space and their acquisition of verbal referents for them were observed. It was found for subjects in the study that conceptual representations of space relations were…

The paper reviews a theory advanced by Satz and Sparrow (1970) which purports to explain the nature and cause of specific developmental dyslexia, and evaluates several developmental hypotheses which are generated bythe theory. The theory postulates that developmental dyslexia is not a unitary syndrome but rather reflects a lag in the maturation of…

This paper describes studies which investigated the nature of the relationship between number of categories and recall performance in children, and attempted to determine whether the category-recall effect increases developmentally. A series of three studies was designed so that grade level and stimulus difficulty would not be confounded.…

As age and grade increased, recall on all tasks increased; subjects in grades three to six were also seen to have a fully developed Iconic Memory, while only sixth graders had a functionally developed Immediate Memory. (KR)

It is proposed here that adults process orientation information at different levels and that these levels correspond to developmental stages in the coding of orientation in childhood. (Author)
