This study tested the hypothesis that operant response suppression strategies function more effectively when predetermined stimulus context variables are explicitly manipulated as “intervention facilitators”. Specifically, the self-stimulatory “book flipping” behaviours of a young autistic child were subjected to a brief immobilization contingency both in the presence and the absence of a contrived Sd stimulus comparison factor. An ABCBC multiple baseline across settings analysis of the subject's self-stimulatory responding under these conditions revealed a clear enhancement of response suppression effects when the above stimulus control feature was incorporated into the strategy. Results are discussed in light of contextual vs. absolute criteria for defining behaviour as undesirable, and the implications of stimulus control knowledge for suppression programming in general are explored.
