Tests indicate that females have innately less ability to perceive spatial relationships than males, but that proper training can improve spatial performance and reduce this natural disparity. (JD)

Some cautions regarding the early educational uses of optical aids with visually impaired children are suggested, based on widely held assumptions and recent findings in the fields of perception and reading. The change from the sight conservation era to one advocating the maximum use of remaining vision is traced. (Author/SW)

The purpose of this study was to determine if reaction time in the peripheral visual field and size of the functional visual field were altered by augmented levels of physical stress while performing on a bicycle ergometer. (JD)

Perceptual-motor functioning is a cyclic process involving: (1) organizing incoming sensory stimuli with past or stored perceptual information; (2) making motor (internal) decisions based on the combination of sensory (present) and perceptual (past) information; (3) executing the actual movement (observable act) itself; and (4) evaluating the act…

Visual acuity as a function of target position and density was measured in a letter recognition task. A homogeneous pattern of equally-spaced elements was tachistoscopically exposed, where the target was never located at the boundaries of the pattern. The target was marked with a spatial cue to control attentional processes. With such a spatial…

Explored the relationships among visual and auditory perception, academic aptitude, sex, and school achievement. Results indicate visual perception added significantly to prediction of achievement beyond that available through knowledge of a participant's sex and academic aptitude. (Author)

Lists strategies for promoting functional vision use in children with visual and motor impairments, including providing postural stability, presenting visual attention tasks when energy level is the highest, using a slanted work surface, placing target items in varied locations within reach, and determining the most effective visual adaptations.…

Visual fixations were recorded in newborn, 4-, and 8-week-old human infants as they scanned displays that varied in contour length, size, number, and a new metric, CVAL (based on Contour Variability, Amount and Location). One of the findings was that both contour length and CVAL separately accounted for approximatel1 95 of looking-duration…

A low vision clinic is using Fresnel press-on prism lenses to aid veterans with extremely restricted visual fields. (Author/SB)

Witkin's Embedded Figures Test (EFT) was used to measure the changes with age in field dependence and problem-solving ability. Qualitative data concerning problem-solving strategies and quantitative data were collected. EFT was administered to 12 females in each of the following decades: 20s, 30s, 40s, 50s, 60s, 70s. All subjects were moderately…

This review is one in a series intended to develop methods which maximize the use of the existing scientific literature as a basis for predicting human performance. It is concerned with sensory performance in target detection, defined in terms of the "probability of detection" of a flash of light. Two conditions of detection are…

Chapter 4 of "Education of Exceptional Children," a review of the literature for the 3-year period since the issuance of REVIEW OF EDUCATIONAL RESEARCH," Volume 36, No 1, February 1966.

This report discusses the outcomes of a study that explored the feasibility of using vision therapy (VT) as part of an interdisciplinary approach to the education of children with autism. Traditional research on VT has explored its usefulness in helping patients to use both eyes together, improve depth perception, and enhance visual acuity.…

A volume in the "Dimensions in Early Learning Series" this monograph proposes suggestions for parents and teachers to supplement normal classroom procedures in the area of visual learning. Chapter I concludes that a child's development of visual skills is directly influenced by inborn tendencies, physical characteristics, and environmental…
