Purpose: This study explored visual speech influence in preschoolers using 3 developmentally appropriate tasks that vary in perceptual difficulty and task demands. They also examined developmental differences in the ability to use visually salient speech cues and visual phonological knowledge. Method: Twelve adults and 27 typically developing 3-…

Inhibition of return (IOR) is modulated by task set and appears later in discrimination tasks than in detection tasks. Several hypotheses have been suggested to account for this difference. We tested three of these hypotheses in two experiments by examining the influence of cue and target level of processing on the onset of IOR. In the first…

Elementary school students and adults were presented with a paired comparison task of visual complexity in which contour and presence or absence of structure in the patterns were manipulated. Results indicated that complexity judgments of all subjects were affected by the presence of structure at lower levels of contour. (GO)

Four studies with infants and preschool-age children examined various pattern perception tasks considered to be related to the perceptual basis of the development of reading skills. Study 1 used 28 neonates to test the hypothesis that supplemental stimulation (rocking, patting, holding) has measurable effects upon attention to visual patterns.…

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…
