This article reports on a method for calculating the space-saving capacity of all Grade 2 braille contractions and the literary braille code as a whole. The study found that, contrary to the widespread belief that contracted braille saves 31% over print, the actual text reduction is about 20%. (Author)

The article describes current research on stereotypes in a group of blind children in Barcelona, Spain. Mannerisms and blindisms covering a range of verbal and motor behavior are defined and discussed, as are the variables of behavior related to them. (Author/DB)

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 the accuracy of 9 pointing methods used by 20 blind adults. Substantial differences were found, with the most accurate methods involving a body part or extension. The verbal "clockface" was the least accurate and most variable method. The long cane is recommended as a pointing method for adults in applied and…

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.…

This study of 12 individuals with blindness or low vision extended earlier studies by Morton Heller concerning speed and accuracy of reading noncanonical (tilted) braille text. Results were similar for Heller's original character set (B-J), but the effect of orientation was reduced with other letters and whole words, especially for experienced…

This study examined the attitudes and values of 47 able-bodied, 36 blind, and 44 wheelchair-using individuals toward various aspects of marriage including love, sexual life, parenthood, and infidelity. No significant differences were found in attitudes and views among groups. All valued marriage and family life highly and had similar expectations.…

Differential reinforcement of low rates of responding was used to reduce the disruptive behaviors of a blind 12-year-old boy with a learning disability. The subject earned reinforcers by not exceeding the established criterion of disruptive behaviors. An overall 88 percent reduction in target behaviors was observed across a 26-day period.…

This article reviews research on the biomechanical elements related to the most commonly used long cane technique, the two-point touch, by individuals with blindness or low vision. The use of several natural biomechanical tendencies supports the contention that the technique is inherently efficient. (Contains references.) (Author/DB)

Two word/nonword decision experiments were carried out to investigate differences in reading between congenitally blind children reading Braille and sighted children dealing with print. Three aspects of single-word recognition were studied: semantic processing, word frequency effects, and phonological recoding. (Author/RH)

This study evaluated the ability of 40 blind adults to spatially organize large outdoor places using a verbal response survey and a near space lapboard task. The study found a high correlation between performances on the large outdoor environment with and without sighted guide tasks. The lapboard task also predicted performance in the outdoor…

The study with three blind and mentally retarded adults with additional disabilities found that general case simulation instruction in housekeeping skills led to generalization to untrained settings. Degree of generalization was inversely related to the severity and complexity of participant disability. (Author/DB)

Comparison of 2 totally blind, 2 visually impaired, and 9 normally sighted children (ages 5-8) on tasks of visual perspective taking found that the totally blind children were older than the other children when they mastered the tasks, made the highest percentage of errors before mastery, and made different errors. (Author/DB)

Point and linear symbols that represent certain areas of building interiors are discussed in light of their reliability and discriminability if used on tactual maps. A set of "optimally sized" symbols were evaluated with 21 blind observers. (Author/DB)

This study investigated the relationship between habitual physical activity and aerobic capacity in 30 blind and 30 sighted adolescents. Both physical activity and maximal oxygen consumption were significantly higher among the sighted adolescents. A minimum of 30 minutes of daily activity at a minimal oxygen consumption of 8 METs (resting…
