Attempts to explain differences between human and nonhuman sensitivity to changing contingencies have centered around humans' language ability, and more specifically on instructional control. The present study was conducted to investigate the role of various histories of rule-governance on the resurgence of rule-following during extinction. Results illustrated that specific rule-following histories reduced trials to criterion and enhanced extinction induced resurgence, when compared to general rule-following or no rule-following histories. A concurrent verbal "think-aloud" procedure demonstrated that these results were caused not entirely by experimenter-provided rules, but also by subjects' generation of self-rules. Implications for the utility of instructional control with human subjects and rule-governance more generally are discussed.
