Extinction response rates were higher for subjects exposed to a FI schedule compared to control CRF schedule subjects (observed PCC value: 0.67, observed c-value: <0.01; complete PCC value: 0.34, c-value: <0.01). However, extinction response rates for subjects exposed to the FI 15-sec schedule were not smaller than response rates for subjects exposed to the FI 30-sec schedule (PCC value: 0.55; c-value: 0.32).

^*Subject stopped returning before the extinction condition.
