Repeated resurgence with and without a context change.

Resurgence is the reoccurrence of a target response when reinforcement for a more recently reinforced alternative response is eliminated or reduced. The present study arranged two successive three-phase procedures to assess whether resurgence decreases with repeated assessments. Moreover, we arranged a contextual change from the first to second assessment for some groups. Phase 1 reinforced a target response on a touchscreen computer with typically developing adults as participants according to either variable-ratio or variable-interval schedules of reinforcement. Phase 2 extinguished target responding and reinforced alternative responding. Phase 3 tested for resurgence by extinguishing alternative responding. Resurgence reliably occurred in all tests and decreased from the first to second exposure to the procedures but there were no effects of context change. Therefore, repeated exposures to resurgence tests reduced those effects but contextual changes had no effect.
