Twenty-four children aged five and twenty-four children aged six were interviewed individually three times during a calendar year. It was found that not only did the children's language develop over the period, as judged syntactically and lexically, but they also showed an increasingly fluent control over their own style. All the children…

An assessment was made of 5- and 8-year-old children's performance on a short-term memory task under two auditory and two visual distraction conditions, as well as under a nondistraction condition. Performance under nondistraction was found to be superior to that under distraction (p<.001), indicating that the extraneous stimuli had a generally…

Piaget, in describing the sequence of classificatory development, describes class inclusion as composed of two processes; hierarchical classification and post-whole comparisons. In the experiment reported here, elementary school children, trained in the concept of sets in first grade mathematics were given a task where they were required to assess…

Major finding of this study demonstrates clear support for the proposed developmental sequence of gestural representation. (Authors)

The development and interrelationship of various measures of independence in children ages 3-12 are examined. Subjects were scored on measures of locus of control and achievement motivation and were rated by teachers on independence and achievement. Subjects were also scored on reliance on adult evaluation and self-evaluation. The results showed…

The present study used a set of bimodal (auditory-visual) conflict designed specifically for the preschool child. The basic component was a match-to-sample sequence designed to reduce the often-found contaminating factors in studies with young children: failure to understand or remember instructions, inability to perform the indicator response, or…

These results demonstrate the kindergarten child's relative inability to produce ongoing thematic activity when this activity is physically separated from the objects involved. (Authors)

Study sought to provide developmental data about the age at which a child will not only color the same object the same color in a reliable fashion, but will also use the correct color." (Author)

The purpose of the study was (1) to examine the results from a two-association perceptual-motor task as to their implications for Luria's theory about the development of verbal control of non-verbal behavior; (2) to explore the effects of various learning experiences upon this development. The sample consisted of 20 randomly selected children in…

Three experiments involving balance scale problems were used to characterize and explain developmental differences in three domains of children's thinking: existing knowledge about the problems, ability to acquire new information about them, and process-level differences underlying developmental changes in the first two areas.

Preschool, first-grade, and fifth-grade children served as Ss in 2 experiments designed to test the developmental hypothesis that memorizing and perceiving are functionally undifferentiated for the young child, with deliberate memorization only gradually emerging as a separate and distinctive form of cognitive encounter with external data.…

This experiment was designed to explore the effects of simple and remedial altruism upon children's subsequent self-reinforcement, generosity, and performance quality estimates. (CS)
