ESTABLISHING USE OF CRUTCHES BY A MENTALLY RETARDED SPINA BIFIDA CHILD1

Abstract: A 5‐yr‐old mentally retarded spina bifida child was taught to walk with the aid of crutches. This behavior was developed through fading of physical prompting within a 10‐step successive approximation sequence. Preliminary training to establish gait consisted of developing use of parallel bars through fading of physically modelled responses within a six‐step successive approximation sequence. Use of parallel bars ceased during an extinction period and completely recovered upon being primed with one “free” reinf… Show more

“…A few studies have introduced subjects to semicontrived or redesigned "natural" reinforcement communities. A simple but meaningful example was provided by Horner (1971), who taught a 5-yr-old institutionalized retarded boy to walk on crutches in an experimental setting. The child was then prompted to generalize the new walking skill to other settings and activities to which he previously had been taken in a wheelchair by solicitous caretakers, by enlisting those caretakers to refrain from offering this help.…”

“…Program Implementation Behaviors Because most of Sunland's clients were nonambulatory or minimally ambulatory, the physical-therapy department there strongly advocated ambulation training. Successful implementation of an ambulation program is characterized by an extremely complex behavior interaction between staff and client, in which each performs the behavior targeted by the program (Horner, 1971;Meyerson, Kerr, and Michael, 1967;O'Brien, Azrin, and Bugle, 1972). However, as illustrated in Figure 2, such an interaction is only one of the four possible interactions a staff/client pair could exhibit.…”

“…There are a limited number of research reports available which demonstrate substitution of naturally occurring reinforcers as a method of promoting generalization and response maintenance (Hopkins, 1968;Horner, 1971;Jones & Kazdin, 1975). Hopkins (1968) taught a severely retarded child to smile contingent upon receiving candy reinforcement.…”

“…Eventually the candy was withdrawn while smiling behavior was maintained through attention received from others. In another report, a moderately retarded child was taught to use crutches through a task analysis skill sequence (Horner, 1971). Use of parallel bars, prompting, and primary reinforcement was gradually faded to independent use of the crutches as the child discovered the naturally reinforcing aspects of his increased mobility, i.e., play and school.…”
