Students coming at present to technical universities are accustomed to television and the visual perception is their prime source of information. This is why our civilization is being often labeled as the "civilization of picture". The contemporary psycho-physiological researches, along with the Dale's cone of human perception, also…

Many simple experiments can be performed in the classroom to explore the physics of vision. Students can learn of the two types of receptive cells (rods and cones), their distribution on the retina and the existence of the blind spot.

The central and peripheral visual fields are structurally segregated in the brain and are differentiated by their anatomical and functional characteristics. While the central field appears well suited for tasks such as visual search, the periphery is optimized for rapid processing over broad regions. People vary in their abilities to make use of…

DYSLEXIA IS DEFINED AS A FORM OF VERBAL AMNESIA IN WHICH THE PATIENT HAS LOST THE MEMORY OF THE CONVENTIONAL MEANING OF GRAPHIC SYMBOLS. DEVELOPMENTAL DYSLEXIA HAS LONG BEEN THE SUBJECT OF PROFESSIONAL DISPUTES IN MEDICINE, EDUCATION, AND PSYCHOLOGY. THE BOOK TRACES THE GROWTH OF KNOWLEDGE ABOUT DYSLEXIA AND DESCRIBES CONFLICTING IDEAS AS TO…

A program was described whose essential aim was to see things at once both more acutely (structure) and more broadly (context), to develop accurate and alternative means for communicating one's particular visual awareness, and in so doing discover processes involved, making them part of one's consciousness and applying them to "daily" situations,…

A position paper written in response to an article on visual perception and reading by S. Alan Cohen (Journal of Learning Disabilities, V2, N10, Oct., 1969). (RJ)

Illustrated are landmarks in the development of speechreading and its role in speech perception by individuals with impaired hearing. Covered are historical influences from 1450 to the present and issues in teaching/learning speechreading, such as the most effective unit of analysis for instruction and the impact of linguistic context. (JDD)

A computer-displayed 3-D tic-tac-toe game was used to investigate adult perceptual biases in dealing with diagonal line orientations. Also investigated was the interaction between prior spatial ability and the effects of explicit visual modeling and structured practice on performance. Results indicated a strong selective difficulty in dealing with…

This handbook, written for parents, teachers, and others working with children for the purpose of early recognition of defective visual perceptual functioning, presents a training program designed to improve visual perception and suggestions for implementation of this program. To assist the trainer in establishing a beginning level for training,…

Presents an overview of some of the major concerns for teachers of Image Study in higher education and offers examples of image sets useful for concept teaching. (MH)

The use of a nonvisual tactual and auditory tutorial method to teach initial reading skills to 16 reading disabled children (ages 7 to 14) was evaluated. The method was shown to be less effective than sighted methods. (DB)

Discusses the value of making students visually literate. Stresses the technique of visual rehearsal and offers suggestions for incorporating visual rehearsal activities into the classroom. (FL)
