Previous studies indicate that the benefits of dividing an information processing load across both cerebral hemispheres outweigh the costs of interhemispheric transfer as tasks become more difficult or cognitively complex. This is demonstrated as better performance when two stimuli to be compared are presented one to each visual field and…

Several studies have indicated that children have difficulty differentiating mirror-image stimuli. In the present study adults were required to classify pairs of horseshoe stimuli as same or different. Response times were compared for stimulus pairs that varied in orientation (left-right vs up-down) and spatial plane of the pair (horizontal vs.…

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…

Two important processes in the acquisition of visually presented information are the ability to maintain discrete perceptual events as separate in time and the ability to abstract information from brief exposures. Five phenomena were measured which appear to reflect these abilities. Critical Flicker Frequency (CFF) is the intermittency rate at…

Literature dealing with the disadvantaged is cursorily reviewed and questions raised by the literature are considered. Specifically, this study concerns the relationship between social class and the rate of processing of visual information in young children. Although various sources of slowness in learning are mentioned, this study focused only on…

CHANGE IN INFORMATION PROCESSING AND CHANNEL CAPACITY WITH INCREASE IN AGE WAS STUDIED, AND POSSIBLE ALTERING OF THIS RELATIONSHIP WITH A CHANGE IN COMPLEXITY AND DIMENSIONALITY OF THE STIMULUS PRESENTED. VISUAL STIMULI WERE PROJECTED ON A SCREEN TO FOUR GROUPS COMPOSED OF 74 COLLEGE GRADUATES, RANGING IN AGE FROM 23 TO 68 YEARS, IN A SIMULATED…

The question of whether pupil diameter indicates information processing load during reading was investigated in three experiments involving 24 college students reading passages of varying difficulty. A TV camera and monitor, together with a video-recorder, were used to measure the diameter of the pupil under a reading condition and under three…
