The ability of 31- to 36-month-old children to act in accordance with rules was assessed in 2 slightly different experiments using sorting tasks and knowledge tasks. Taken together, the results of both experiments imply a relatively rapid, age-related change culminating in the ability to systematically execute rules that require access to extant…

Results were interpreted in terms of current conceptions of age differences in information-processing speed. (Author)

Reports an attempt to test two interpretations of immanent justice responses as causal attributions rather than as moral judgments. Finds older children use causal chains to explain contiguity between misdeed and adversity. Data were interpreted as consistent with an information-processing model of immanent justice responses.

Investigates performance of 8, 10, 12 year olds and adults on cognitive tasks in terms of several processing-speed measures, each of which may change independently with age. Results underscore the complexity of developmental change in processing efficiency. (Author/RH)

Suggests that the information integration processes used by adults to form judgments are also used by children. (ST)

In a schematic concept formation task, second and fifth graders were required to sort 60 computer-generated, 8-sided polygons into two classes. The results indicated that age differences in schematic concept formation are due more to the efficiency of information use than to differences in strategy or the selection of information to be used.

Results suggest that selective attention is a multifaceted skill, with development of its parts progressing at different rates. (Author)

One question prompting the present research concerned the relation between performance under tachistoscopic'' conditions where exposure durations are too brief to permit active overt visual search, and performance when overt search is possible. (Author)
