Young men with autism working on a vocationally relevant task served as participants in two experiments that extended previous research on pausing and escape during signaled transitions between relatively rich and lean schedules of reinforcement. In Experiment 1, pause duration was longer for all participants when the upcoming schedule component was lean. In Experiment 2, each component of a multiple schedule began with an opportunity to emit an escape response. There were two conditions: A) escape from schedule-correlated stimuli (the task continued to be available) and B) escape from the stimuli and the scheduled task, which were again presented following a second response. All participants engaged in some escape responses; duration of escape in Condition B generally mirrored duration pausing for each participant. We encourage practitioners to consider the potential aversive qualities of stimuli in signaled transitions. Presented at CEC-DADD, 2015, ABAI 2015, BABAT 2015, ICEABA 2015.
