The use of conditional probability analysis to identify a response chain leading to the occurrence of eye poking.
In contrast to the literature on shaping adaptive behavior chains, few applied studies have described procedures for identifying and treating behavior chains involving problem behavior such as self-injury. The present study expands upon past work by conducting a conditional probability analysis and within-session analysis to identify a response chain leading to the occurrence of self-injurious behavior. Based on the hypothesis that stereotypy and self-injury constituted a response chain, the effects of blocking stereotypy were examined. Reductions in both self-injury and in response effort for treatment implementation were observed.
