Describes an automated microcomputer system that can present precise stimuli and record accurate responses and discusses its use in studying and training retarded and psychotic children. It is noted that training procedures that require the children to utilize visual, auditory, and bimodal stimuli can be automated with the system. (MBR)

Examined the relationship between responsiveness to auditory novelty in full-term and preterm infants and subsequent intellectual performance at five years of age. Results suggest that measures of early perceptual-memory development may reflect early cognitive processes necessary for later intellectual performance. (Author/RH)

The relationship between psychometric intelligence and rapid acoustic information processing was explored in two experiments using college students. Group differences occurred in threshold interstimulus intervals required for recognition and in speed. Results were interpreted as indicating better information processing efficiency (higher…

The purpose of this study was to test the principle of modality by using audio to deliver verbal information when that information is designed to support non-verbal information such as animations in a computer-based lesson. This was done by comparing the effect of two types of audio support mechanisms- a simple support mechanism consisting of…

The purpose of the experiments reported in the present paper was to explore further the characteristics and duration of representational persistence, using the word recognition paradigm of Shepard and Teghtsoonian (1961). (Author)

The present research is concerned with preference for visual (polygon) complexity versus simplicity in relation to national membership, using adult subjects from five nations (cultures) four groups of which were temporarily resident in the U.S.A. (Author)

From collective improvisation in Afro-American music arose liberated improvisations designed to exhibit personal virtuosity. But that was all that changed; spontaneity and personal sound remained the most interesting components of the music. (Author/RJ)

Examines the importance of (1) dimensional characteristics of stimuli present in discrimination transfer tasks, (2) having contrasting stimuli presented simultaneously, and (3) subjects age. Subjects were rural Mexican youths, ages 4 to 10. Reversal and nonreversal type discrimination transfer problems were used in the study. (DP)

Two experiments were conducted investigating the extent to which transfer of training would take place. (Editor)

Second grade Ss and college students were tested under three conditions of the temporal relationship of feedback and stimulus information. (Editor)
