Guy, Jacalyn; Rogers, Maria; Cornish, Kim – Infant and Child Development, 2012
The development of executive functions in the preschool years is not fully understood. Although there exists a large body of research investigating the maturation of executive functioning in school-aged children, little is known about the emergence of such skills, in particular inhibition, among preschool-aged children. Understanding developmental…

Simpson, Tamara; Camfield, David; Pipingas, Andrew; Macpherson, Helen; Stough, Con – Educational Gerontology, 2012
In an increasingly aging population, a number of adults are concerned about declines in their cognitive abilities. Online computer-based cognitive training programs have been proposed as an accessible means by which the elderly may improve their cognitive abilities; yet, more research is needed in order to assess the efficacy of these programs. In…

Wijnen, Jasper G.; Ridderinkhof, K. Richard – Brain and Cognition, 2007
Previous research has shown that the appearance of task-irrelevant abrupt onsets influences saccadic eye movements during visual search and may slow down manual reactions to target stimuli. Analysis of reaction time distributions in the present study offers evidence suggesting that top-down inhibition processes actively suppress oculomotor or…

Rosser, Rosemary A. – Child Study Journal, 1994
A study examined how well children could discriminate matches from nonmatches of multicomponent stimuli within the prototypic mental rotation task and how long it would take them to make such discriminations. The goal was to determine whether children are differentially sensitive to the various spatial features of visual stimuli and whether…

Melowsky, Fred; Ray, Joseph B. – 1975
A comparison of test results on the Visual Discrimination Test was made between a group of 22 reading disabled children and 22 children who were reading on or above grade level. Both groups were of average or above-average intelligence and the two groups were matched for age and sex. The mean age was 10 years and 3 months and all the reading…

Johnson, Mark H.; Tucker, Leslie A. – Journal of Experimental Child Psychology, 1996
Discusses changes occurring in two-, four-, and six-month-old infants' visual attention span, through a series of experiments examining their ability to orient to peripheral visual stimuli. The results obtained were consistent with the hypothesis that infants get faster with age in shifting attention to a spatial location. (AA)
