Provided in the second of two articles is further evidence of the validity of the author's sequence of tactual discrimination tasks for partial development of Optacon use readiness in young blind children. (IM)

This study compared the performance on perspective-taking tasks of 8 congenitally blind children (mean age 13.5 years), using either haptic exploration or a vibrotactile prosthetic device, with the performance of 4 children having low vision using their limited visual abilities. The vibrotactile device improved perspective-taking performance…

Performance of congenitally blind children and blindfolded children was compared on tasks requiring spatial reasoning and shape recognition. Blind subjects performed at least as well as blindfolded subjects on simple two-dimensional tactual processing tasks, but less well on more complex tasks requiring them to store, compare, and label objects.…

This article reviews recent research on perception of tangible pictures in sighted and blind people. Haptic picture naming accuracy is dependent upon familiarity and access to semantic memory, just as in visual recognition. Performance is high when haptic picture recognition tasks do not depend upon semantic memory. Viewpoint matters for the ease…

This article describes the work of a group of professionals in the United Kingdom known as the VIEW Braille Literacy Committee, committed to the development of teaching braille. Members meet each school term and have had the support of the Royal National Institute of the Blind (RNIB) in realizing numerous projects aimed at improving access to…

A follow-up account of a mother's attempts to provide her blind daughter, now aged six, with knowledge of the physical world through the manipulation of three-dimensional objects and two-dimensional tactile representations. The case is made for the value of pictures to the development of children's understanding in general; and for the child who…

Various counting tasks were presented to 24 congenitally, totally blind children, aged 3-13, to determine the behaviors employed to ensure accurate counting. Three dimensions of tactile strategies were found, including "scanning,""organizing," and "partitioning." A developmental progression in the ontogenesis of each…

Twenty students and 45 adults with visual impairments or blindness were administered a test of tactile concentration and short-term memory involving the reproduction of the order of finger stimulation using the Finger Knocking Box. Reliability and validity scores indicated encouraging results with use of the instrument. (JDD)

This case study describes a congenitally blind undergraduate student who successfully completed a basic statistics course. Accommodations specific to his blindness included: a textbook on tape and review tapes before examinations; a talking calculator; graphs made on Braille paper and other tactile teaching aids. Affective problems encountered…

Intended for parents of blind preschool children, the booklet lists games and activities to develop independence by means of tactual, aural, physical, self care, social visual, and mobility training. Activities are listed for the 3-year-old, the 4-year-old, and the 5-year-old under the specific skill developed. Instructions for particular games…

Reports results of the administration of a battery of tests of oral language skills to blind braille readers (N=15). Three skills were tested: phoneme deletion, sentence completion, and morphological analysis. Participants were congenitally blind high school students. Subjects differed from sighted readers only in the ability to perform…

A new psychological test battery was designed to provide a much-needed comprehensive tool for assessing the perceptual and cognitive abilities of visually handicapped children in using active touch. The test materials consist of raised-line, raised-dot, raised-surface shapes and displays, and familiar and novel 3-D objects. The research used 20…

A review of the literature on the spatial functioning of the blind, the results of a questionnaire of 75 sighted college students and their parents, and results of a study of 87 blind and seeing adults' performance on three spatial tasks are presented. The review suggested that adventitiously blind individuals perform better than congenitally…

The author describes several teaching aids and techniques to help blind and partially sighted students understand electronics, specifically devices (with availability) he has found effective in preparing a blind student for a ham radio license: an audital multimeter, raised line drawings, Opticon, braille texts, and Speech Pulse Calculator.

An educational program was designed to introduce spatial concepts to 30 congenitally/early-blinded children, aged 8-14, using a modified Optacon of Telesensory Systems, Incorporated. Using the vibrotactile stimulation device, the children learned to identify various objects correctly and to describe their relative spatial arrangements. (Author/JDD)
