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…

The type of visual information needed for categorizing faces and nonface objects was investigated by manipulating spatial frequency scales available in the image during a category verification task addressing basic and subordinate levels. Spatial filtering had opposite effects on faces and airplanes that were modulated by categorization level. The…

External noise methods and observer models have been widely used to characterize the intrinsic perceptual limitations of human observers and changes of the perceptual limitations associated with cognitive, developmental, and disease processes by highlighting the variance of internal representations. The authors conducted a comprehensive review of…

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…

Twenty normal-hearing, sighted subjects (ages 20-42) viewed soundless videotapes of a speaker reading lists from the two forms of the Utley Lipreading Test and three from Harris' revised Central Institute for the Deaf (CID) Everyday Sentences. Results do not support the interchange of Utley and CID sentences for test-retest comparisons of…

Seven experiments with a total of 480 subjects indicated that subjects visually imaging classical ambiguous figures have difficulty reconstructing the images, and that their construal of the image strongly influences what is depicted within the image. Image content, rather than image inspection, appears to be selective. (SLD)

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…

In the three studies reported here, an attempt was made to determine whether adult native speakers of English can agree on the choice of phonetic labels for visually presented geometric figures. It was the purpose of these studies to obtain evidence in support of the "phonetic symbolism" hypothesis. An initial study and two replications…

The raw data collected in a study to determine the effect of attention in measuring visual perception are provided. A key to the 19 numerical headings of the raw data tabulation is given. Two pages of tables presented the raw data. (For related documents, see TM 002 116,117.) (DJ)

Discusses two frequently recommended tests for the evaluation of visual perception in relation to reading ability: the Frostig Development Test of Visual Perception and the Bender Visual Motor Gestalt Test. Questions the content validity of the former and suggests that the latter is a reasonable predictor of reading achievement. (FL)

Evidence presented by psychologists has indicated that perceptual development results in part from learned experience and may be modified to varying deqrees by social pressure. Since vision is a primary source of perceptual information for art education, this study sought to determine the effects of prophecy, or expectation, on perceptual response…
