A study, including research and practice notes by various authors, investigated whether extended training in an acoustically rich environment could enhance the spatial updating ability of 12 adults with congenital blindness. After training, the adults' distance perception from a home-base location and novel locations was superior to a sighted…

Retinitis pigmentosa (RP) causes restriction of the visual field, progressive vision loss, and night blindness. This article presents an overview of the most common problems in orientation and mobility (O&M) for individuals with RP, appropriate interventions, vision science discoveries related to RP, and the impact of RP on functional visual…

This study evaluated variables that determined the safety of 15 cane users who were using the touch technique. The results showed that none of the walkers used a touch technique as described and recommended in the literature, that the detection of obstacles was related mainly to the height of the cane tip during the sweep, and that the early…

Five elementary-aged special needs students were taught to walk from the entrance of their school to classroom using prompt fading sequence and fading of teacher presence and verbal directions. Results showed both rapid skill acquisition contingent upon the specific training each S received and maintenance of behavior. (Author/CL)

Semistructured telephone interviews with 10 visually impaired adult cane users found that early negative attitudes of stigma were usually replaced by more positive attitudes and that there was a mean of 1 3/4 years between the onset of severe visual impairment and commencement of orientation and mobility training. (Author/DB)

This open-ended survey of 156 subjects (78 pairs of visually handicapped orientation and mobility specialists and adult clients) identified common low vision mobility problems (lighting conditions, drop-offs, street crossings, changes in terrain) and found a high degree of agreement between the reported perceptions of mobility practitioners and…

In an unfamiliar residential neighborhood, 24 10- and 6-year olds were individually evaluated and compared on their conceptual knowledge of the neighborhood. Findings indicate there are statistical and practical differences between the two age groups. Implications for teaching orientation and mobility to children with low vision are discussed.…

In this study, a system was designed for monitoring learning progression and observing how an instructor directs a student's attention toward goals, such as landmarks and shorelines, on mobility routes. Results indicate the system was effective in monitoring the learning progression of 16 students (ages 3-14) with blindness. (Contains references.)…

Five adult students of various ethnic backgrounds, each deaf or hard-of hearing and blind or visually impaired, participated in testing a newly designed assistance card for soliciting help crossing the street. Results indicated that with the new card 101 pedestrians out of 183 offered assistance. (Contains references.) (CR)

Eighteen mentally retarded adults were taught pedestrian skills using either classroom or community training procedures. Community training procedures resulted in significant improvement from pretest to posttest; however no significant change was seen in the classroom group. (Author/MC)

Procedures were evaluated for teaching four institutionalized adult males with profound retardation necessary skills to increase their individual freedom of movement. Following baseline, a travel training program with a backward chaining format was implemented to teach each person to walk independently from his living area to school. (Author)

Three experiments examined the ability of blind individuals and individuals simulating the visual acuity of 20/400 to monitor the behaviors of a cane traveler in various environments and at distances between 10 feet and 25 feet. Results suggested that at least some vision is needed for instructors monitoring visually impaired individuals learning…

This case study discusses how a teacher of three elementary students with congenital blindness motivated her students to increase their mobility. The children were asked to pull a child-sized suitcase with wheels behind them in the hand that was not holding a cane. The successes of the strategy are described. (Contains two references.) (CR)

The article reports a retrospective study of the records of 183 blind men and women who had received mobility training. How well and quickly the trainees learned to travel was affected by age, sex, presence of other handicaps, visual acuity, and whether or not they still traveled at intake or had previously received mobility training. (Author)

Adventitiously blind adults (n=79) who had accepted mobility training were compared to 60 subjects who had rejected training. Personality profiles varied significantly between groups on seven scales of the Minnesota Multiphasic Personality Inventory: psychasthenia; schizophrenia; psychopathic deviate; depression; hypomania; paranoia; and…
