Eighty middle-class and 80 lower-class boys were tested on a visual and a verbal task under 3 conditions designed to modify an impulsive tempo." (Author)

Uni- and multidimensional processing of 6- to 9-year olds was studied using recall tasks in which an array of stimuli was reconstructed to match a model array. Results indicated that both age groups were able to solve multidimensional problems, but that solution rate was retarded by the unidimensional processing of highly salient dimensions.…

Examines the effect of different training methods on perceptual learning of impulsive children. A matching to sample method (M), and a differentiation method (D) were used. Data indicated that Ss receiving D training learned to process features distinguishing stimuli; whereas, Ss receiving M training showed no preference for a particular mode of…

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)

The data indicated that disadvantaged children required more time to process visual information than did middle-class children, but the processing speed for the 2 groups tended to become more similar as grade level was increased. (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)
