Employment data from the 1960 and 1970 censuses were organized using the occupational classification system of John Holland to examine age, sex, and level differences in employment and to detect changes over the 10-year period. Data were organized by both kind and level of work in an attempt to answer the following questions: What are the relative…

This study investigated the effects of two stimulus manipulations (spatial distinctness and number of dimensions) on the performance of 24 kindergartners and 24 fifth graders in (1) tasks requiring distributed attention and (2) tasks requiring selective attention. Results suggest that kindergartners attempt to use one processing mode (distributed…

This paper examines several recent lines of research concerning category clustering and describes an alternative to the standard category clustering procedure used to study recall organization in younger children. The specific issue considered is the age at which children first show evidence of spontaneous category clustering in their free-recall.…

A dissertation proposal involved a study to observe spontaneous behavior of children in interaction with materials in order to gain understanding of the factors that influence classificatory and imaginative behavior in free play. Children at two levels of ability in terms of classification skills were observed in interaction with materials at two…

The relation between conceptual development and visual exploratory behavior was investigated by engaging eighty-four 3-, 4-, and 8-year-old children in a picture-sorting task to determine whether they would spontaneously and readily discriminate between animate and inanimate objects. (Author/JMB)

Examination of the way in which children conceive the development of animals shows that there are parallels among concepts of development with those of the periods of concrete operations and formal operations. The conception of development seems to advance further in the subsequent period of dialectical thought. (MS)

This study investigated whether a pattern for the development of motor ability could be discerned, using the same range of motor performance tests with boys and girls at 10 different age levels. Researchers did not find a pattern as clear as has emerged in personality and intelligence development. (PP)

Word lists were given to 176 Scottish children, ages 15, 11, 8, and 6. Analysis of variance on recall scores indicated that Jensen's findings of greater recall by middle class children may be only a transitory phenomenon, not evidence of permanent middle class superiority in Level II ability.

Compared 28- to 53-month-olds' writing and drawing. Scores on a writing scale composed of graphic, "writing-like," and symbolic schemes improved with age. Recognition of drawings as drawings preceded recognition of writings as writings. Writing and drawing scores were substantially correlated, even with age partialed out, suggesting that…

Followed 150 children over four years who were classified according to cluster analysis of teacher ratings into four types of social withdrawal: unsociable, passive-anxious, active-isolate, and sad-depressed. Found that unsociable children had elevated sociometric neglect rates, active-isolates had higher levels of rejection, and sad-depressed had…

Recall of "to-be-remembered items" benefited from schematically related, superordinate, and slot filler cues, but not coordinate cues. The relative strength of different relationships does not appear to change with age. Findings are consistent with the view that lexical memory is schematically and taxonomically organized from early…

Categorization responses of 6 and 11 year olds and adults to test stimuli were examined against predictions derived from 2 models that stressed prototypical features or information about exemplars. For six year olds, only the prototype model fit the data. For the two older groups, both models explained variance in performance. (PAM)

Assessed developments in the theory of mind suggested by changes in the organization of cognitive verb extensions during elementary school years. Found three major changes with development: increased understanding of the role of memory in input functions, increased interrelatedness of memory- and comprehension-related verbs, and increased…

Two experiments explored the nature of perceptual development in 5- and 10-year olds and adults. The primary finding was that preassessed salience significantly influenced 5-year olds' ability to discriminate two objects, while salience did not affect 10-year olds' or adults' response times. Results showed that salience effects in perceptual…

The current work examined age differences in the classification of novel object images that vary in continuous dimensions of structural shape. The structural dimensions employed are two that share a privileged status in the visual analysis and representation of objects: the shape of discrete prominent parts and the attachment positions of those…
