title: The use of conditional probability analysis to identify a response chain leading to the occurrence of eye poking.
abstract: 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.
