Stimulus control and generalization of remote behavioral history.
Two experiments were conducted to assess stimulus control and generalization of remote behavioral history effects with humans. Undergraduates first responded frequently under a fixed-ratio (FR) schedule in the presence of one line length (16 mm or 31 mm) and infrequently on a tandem FR 1 differential-reinforcement-of-low-rate (DRL) schedule when a second line length (31 mm or 16 mm) was present. Next, an FR 1 schedule in effect in the presence of either stimulus produced comparable response rates between the stimuli. Finally, a tandem FR 1 fixed-interval (FI) schedule was in effect under those same stimuli (Experiment 1) or under 12 line lengths ranging from 7 to 40 mm (Experiment 2). In both experiments, responses under the tandem FR 1 FI schedule were frequent in the presence of stimuli previously correlated with the FR schedule and infrequent in the presence of stimuli previously correlated with the tandem FR 1 DRL schedule. Short-lived but systematic generalization gradients were obtained in Experiment 2. These results show that previously established rates of behavior that disappear when the establishing contingencies are changed can subsequently not only reappear when the contingencies change, but are controlled by and generalize across antecedent stimuli.
