Visual scanning behavior and efficiency of 22 children with visual disabilities and 25 children without disabilities (ages 3.5 to 10 years) were studied. Significant differences were found between groups in length of scan path and number of objects reported, but no significant differences in scanning efficiency. Coordinated binocular eye movements…

Eight stump-tailed macaques were reared individually and either given all of their daily social experience in darkness or given half in the dark and half in the light. Results suggest that vision is especially important in the maintenance of assertive behaviors and in the instigation and direction of aggressive behaviors. (Author/RH)

Describes subjective-contour illusions and gives explanations for perception of shape and brightness in these figures. Supports cognitive mechanisms rather than psychological mechanisms. Gives examples of subjective-contour illusions and summarizes explanations of other psychologists with regard to this topic. (CW)

Compares monocular depth perception with binocular depth perception in five- to seven-month-old infants. Reaching preferences (dependent measure) observed in the monocular condition indicated sensitivity to monocular depth information. Binocular viewing resulted in a far more consistent tendency to reach for the nearer object. (Author)

Describes the three part system of human vision. Explores the anatomical arrangement of the vision system from the eyes to the brain. Traces the path of various visual signals to their interpretations by the brain. Discusses human visual perception and its implications in art and design. (CW)

The study compared the effectiveness of Irlen filters and traditional optometric intervention with 30 volunteers (ages 9-51). Pre- and posttesting revealed that subjects in both treatment groups were more comfortable after treatment, that only the vision therapy group showed improved visual functioning, and that the Irlen filter group did not show…

This paper examines work in eliciting conceptions of light and vision that are held by naive learners and about some promising instructional strategies that emerge from this work. Naive learners are defined as subjects that have not had formal exposure to the physics of light, particularly elementary school children who were interviewed in the…

Describes four models of the psychological process of reading, and relates them to computer technology. The physiological process of reading printed text from a display screen is discussed, including spacing, the configuration of letters, vision problems, and lighting and glare. The quality of computer printouts is also discussed. (41 references)…

Describes a corrective method of color adaptation designed to allow most, if not all, individuals to participate in the learning process as well as social and work-related environments. Provides a concise summation of facts and theories concerning color deficiency. Includes anatomical drawings, graphs, and statistical data. (MJP)
