- Abstract
In experiment 1, an extended functional analysis of self-injury was conducted with a 21-year-old male diagnosed with autism and profound mental retardation. The multielement phase yielded undifferentiated results. Subsequent blocking of conditions plus the addition of a component allowing access to multiple sensory stimuli suggested that self-injury was unrelated to programmed positive or negative reinforcement contingencies. The behavior appeared to be automatically reinforced; its occurrence decreased when access to alternative sensory stimuli was provided. Experiment 2 evaluated a treatment condition in which response-independent access to these sensory stimuli was provided within the participant's everyday environment. Baseline and treatment frequencies of self-injury were compared in a combined, multiple-baseline-across-settings and ABAB design. The level of self-injury decreased substantially during treatment. These results support the use of extended analog analyses of aberrant behavior in instances in which undifferentiated responding occurs in the initial analogue analysis. Additionally, a procedure is described for generalizing the intervention derived from the experimental analysis into the participant's everyday environment. Copyright © 2001 John Wiley & Sons, Ltd.
