Eight experiments, each with 10 observers in each condition, show that the visual search for Mueller-Lyer stimuli is based on complete configurations rather than component segments with preemption by low-level groups. Results support the view that rapid visual search can only access higher level, more ecologically relevant structures. (SLD)

This paper is simultaneously a test and refinement of the E-Z Reader model and an exploration of the interrelationship between visual and language processing and eye-movements in reading. Our modeling indicates that the assumption that words in text are processed serially by skilled readers is a viable and attractive hypothesis, as it accounts not…

In 3 experiments, the author investigated 16- to 20-month-old infants' attention to dynamic and static parts in learning about self-propelled objects. In Experiment 1, infants were habituated to simple noncausal events in which a geometric figure with a single moving part started to move without physical contact from an identical geometric figure…

Psychological research shows that learning can be powerfully enhanced through testing, but this finding has so far been confined to memory tasks requiring verbal responses. We explored whether testing can enhance learning of visuospatial information in maps. Fifty subjects each studied 2 maps, one through conventional study, and the other through…

The Program of Systematic Evaluation (PSE), which began as an attempt to explore the instructional dimensions of multimedia, has evolved into the most comprehensive set of experimental multimedia studies exploring the varied dimensions of cognitive load theory as they relate to the design of effective and efficient visual learning environments for…

Those who focus on the study of visual information continue to search for effective ways to conceptualize that inquiry. However, many visual examples are better categorized as visual/verbal collaboration, complicating analysis. When analysis is based on the assumption that visual and verbal modalities perform in similar ways, important…

This study examined whether children with mathematical difficulties (MDs) or comorbid mathematical and reading difficulties have a working memory deficit and whether the hypothesized working memory deficit includes the whole working memory system or only specific components. In the study, 31 10-year-olds with MDs and 37 10-year-olds with both…

PowerPoint and other visual technologies have become pervasive in schools. Adoption of these technologies is perceived as a necessary--or, at the very least, an educationally appropriate--innovation in UK schools, even though systematic examination of their use is relatively recent. On the basis of a wider ethnographic study of ICT use in one UK…

The goals of this study were to identify the constructs of visual literacy, to determine the amount of agreement or disagreement which exists concerning the identified constructs, and to provide a measure of relative importance among the identified constructs. The Delphi technique was employed to elicit information and opinions from a panel of…

A model is described to suggest how the visual system may keep track of perceived objects as their images move on the retina. (Author)

EXPERIMENTS WERE CONDUCTED TO DISCOVER WHETHER INSTRUCTIONAL FILMS IN COLOR WERE MORE EFFECTIVE THAN BLACK AND WHITE VERSIONS OF THE SAME FILMS. IN ONE EXPERIMENT, COLOR AND BLACK AND WHITE VERSIONS OF FIVE INSTRUCTIONAL FILMS WERE SHOWN TO 500 NINTH- AND 10-GRADE STUDENTS, HALF THE STUDENTS SEEING THE COLOR FILMS AND THE OTHER HALF SEEING THE…

Eye Movements were used as a criterion of observing responses in a vigilance task. Time on watch and signal rates similarly affected both eye-movement rates and percentage of detections. Observing rate may account for detection data, and may be a more stable measure of vigilance than detection rate, especially when very few signals occur. This…

Learning through the use of symbols presupposes the ability to think visually, including the perception, structuring, processing, and transformation of visual images. Since children process high volumes of visual messages, especially via television, schools should restructure curricula to include objectives in visual literacy, specifically the…

The study employed the use of field reversals--printing white and yellow foregrounds on a black background--to decrease the amount of light reflected from printed materials to the eye with 18 visually impaired children (9-14 years old). The findings indicated that neither reversals in contrast nor chromaticity differences were effective measures…

The relationship between each of seven predictor variables and the relative degree to which 84 normal and hearing-impaired children used audition or vision in their perception of word stimuli were investigated. It was concluded that the relative use of audition was almost completely related to their auditory capabilities. (Author/CL)
