Response recurrence and behavioral
history. Gregory A. Lieving, Adam H. Doughty, Megan Meginley, Stephanie P. Horne And Kennon A. Lattal West Virginia University, USA The present experiments examined some of the conditions under which extinguished responding may reappear despite the continued non-reinforcement of such responding. In one preparation, labeled reinstatement, responding was extinguished and then reinstated by delivering food independently of responding. In another, labeled resurgence, responding was extinguished on one operandum and then reinstated when reinforcement on a second operandum was discontinued. During each experiment, either 2-component concurrent or 2-component multiple schedules were used. In some conditions, response rates and reinforcement rates prior to extinction were different between the two components. In other conditions, either reinforcement rate or response rate was held constant in both components and the other was varied systematically to assess the contributions of both response rate and reinforcement rate to the reappearance of extinguished responding. Differential recurrence of key-peck responding by pigeons was observed as both reinstatement and resurgence as a function of rates of responding during the pre-extinction training conditions. Such differential recurrence is taken as index of behavioral history and, in line with other types of investigations of behavioral history effects, suggest that response rates play an important role in behavioral history effects.
