Lowenfeld (1945) developed a series of six instruments which could be used to identify perceptual abilities. For this study, the visually oriented person was defined as the objective viewer of the environment, while the haptic person was defined as a person who uses the eyes only when forced to do so and relates to his environment subjectively. He…

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…

A study evaluated the ability of a dynamic visual assessment and training protocol to improve the ability of 65 persons with legal blindness to detect environmental hazards. Training improved the ability of the majority to detect hazards. The assessments also identified those who did not need training or would not benefit. (Contains references.)…

This study, involving 20 children (ages 6-12) with legal blindness or partial sight, explored the relationships between ability to read and performance on tasks which require the manipulation of figure/ground relations. Significant differences were found between fluent readers and poor readers/nonreaders on four of the six tasks. No age…

The diagnosis and treatment of early learning problems and their relation to visual development is the subject of a series of 12 articles. The optometric viewpoint expressed is that vision is learned. A child's method of organizing his world, and manifestations of his disorganized behavior, including poor early academic achievement, probably…

An experimental test of visual closure based on an information-theory concept of perception was devised to test the ability to discriminate visual stimuli with reduced cues. The test is to be administered in a timed individual situation in which the subject is presented with sets of incomplete drawings of simple objects that he is required to name…

Practice in interpreting the critical features of incomplete line drawings and integrating fragmentary visual information was shown to enhance the visual efficiency of partially sighted children, aged 5 to 8. (BW)

Over a period of three years a group of 510 rural children participated in a study of visual perceptions, including eye motor coordination, discernment of figures in a ground pattern, form constancy, position in space, and spatial relations, as measured by the Frostig Visual Perceptions Test. Visual perceptions of children of other cultures were…

This screening and diagnostic procedure is intended to identify Level 1 adults with specific learning problems. The adults not meeting criteria on the assessments for visual and auditory functions should be referred to proper medical services for full evaluations. A prescriptive teaching program should be specifically designed to meet needs of…
