A cell-by-cell analysis of finger movements of 16 blind adolescent braille readers was conducted to separate, catalog, and measure the components of scanning movements across braille cells as a function of reading proficiency. Results confirmed the superiority of bimanual reading and suggested that the two hands may perform different functions.…

This study evaluated performance of blind (n=17) and sighted adults on a haptic numerosity task of braille symbols in which symbol size was varied. Although blind subjects performed better than seeing subjects, the rate of learning and patterns of errors were similar, except that blind subjects did better with standard than with enlarged symbols.…

The article suggests that Belcastro rods, which retain the basic properties of Cuisenaire rods but allow instant identification by touch, may be useful in teaching mathematical concepts to blind children. Drawings illustrate use of the rods in teaching such concepts as addition and subtraction. (Author/DB)

A framework for studying individual variation in tactile map reading is offered and a set of research guidelines suggested. It is argued that the reading process may be viewed as a many-leveled set of skills viewed from an information processing rather than a psychometric perspective. Individual variations are studied and classified. (Author/PB)

Analysis of completed surveys from 230 teachers of blind and visually impaired learners found that preservice training programs emphasizing the methodology of teaching Braille and the development of tactual perception tended to produce teachers who have positive attitudes toward Braille and feel competent in teaching Braille to children.

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)
