This study assesses the validity of an interview questionnaire designed to predict performance by low-vision adults (N=41) on tasks of finding, detecting, scanning, and tracking. Subjects' ratings of difficulty with these tasks were compared to ratings of trained professionals. Results indicate self-report may be of some value in predicting…

To investigate whether screen color is an important variable in the prescription of closed circuit television (CCTV) systems, 16 adults with low vision were assessed on reading performance on white, green, and amber screens. When the screen luminance and contrast were equated for each CCTV, subjects' reading performance was unaffected by screen…

This paper offers a model of visual functioning focusing on three factors: (1) visual capacity, (2) visual processing, and (3) visual attention. Practical implications of visual therapy are considered, and intervention strategies with children with impaired visual functioning are suggested. (Author/DB)

Comparison of 2 totally blind, 2 visually impaired, and 9 normally sighted children (ages 5-8) on tasks of visual perspective taking found that the totally blind children were older than the other children when they mastered the tasks, made the highest percentage of errors before mastery, and made different errors.

The article proposes helping visually handicapped clients make optimal use of remaining vision for travel in unmodified environments. Structured discovery learning exercises covering pattern recognition, depth perception, central acuity, and central field vision with peripheral field loss are offered. (Author/DB)

Twenty-five older adults with age-related macular degeneration were separated into one of three groups: in-clinic training, take-home-training, or no-training. After testing, results showed that the ability to distinguish figure from ground is an improvable skill with the take-home group improving the most. (Author/DB)

Discussed is the nature of a central scotoma, or decreased central vision, and described are current techniques for training an individual to use the peripheral retina. (Author/IM)

This article describes a visual assessment procedure (VAP) which evaluates capacity, attention, and processing (CAP) of infants and preschool children with visual impairments. The two-level battery considers, first, visual capacity and basic visual attention and, second, visual perceptual and cognitive abilities. A theoretical analysis of the…

An analysis of questionnaires completed by 94 partially sighted children and their parents attempted to identify the visual environmental adaptation problems (VEAPs) of children in regular classrooms. Significant VEAPs were found in classroom tasks, in tasks that required the resolution of fine detail, and in some mobility tasks. (Author/DB)
