Assesses subjects' information output after presentation of pictorial, word, and sentence stimuli. Output is measured in two modes of response: reconstruction and verbal description. Complexity of the stimuli is demonstrated to have important effects on perceptual information processing. (DP)

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…

The present paper is concerned particularly with the processes underlying the perception of the upright, that is, an object in its usual, or familiar, position in space. (Author/RK)

That there are differential rates of development of cross- and within-modal integration is not supported by the present results. (Authors)

Results of two experiments show that only postinformative feedback intervals to be significant sources of variation; mean trends appeared to indicate that extended preresponse intervals interfere with performance, if anything. (Authors/MB)

Results are consistent with the hypothesis that sequential memory is dependent upon the availability of a verbal memory code. (Authors)

Both acquisition and retention were better when the hierarchy was learned graphically rather than as a list of associations, although the effect was greater on acquisition than on retention. (Authors)

Purpose of the study was to evaluate the effectiveness of a hierarchically arranged instructional program in multiple classification, which refers to the ability to define a class by two or more attributes simultaneously. (Authors/MB)

An attempt to identify instructional methods based on the "urban Negro Child's interest in concrete and motoric experiences which will help him acquire basic skills and assist him in discovering and responding to sensory experiences. (Author)

The findings of this study do not support certain longstanding assumptions regarding the importance of delay in writing and extension of experience in increasing syntactic complexity and clarity in children's writing. (Author)

Investigation indicates that perceptual inadequacy must be controlled in studies that utilize ambiguous, novel or nonsense designs in stimulus materials. (Authors)
