Mean (±SEM) proportion of trials in which escape responses were emitted. Escape contingencies are described in parentheses using the format RL:LL:D, where RL is the Response-Light interval, LL is the Light-Light interval, and D is the duration of the light. The three baseline [(20:5:10), (20:5:5) and (20:5:5)] conditions were intermittently followed by conditions in which no light (0:0:0) was presented, bright light was made inescapable (0:5:5) and in which the Sidman avoidance contingency was debased (5:5:5). Results from the Mixed ANOVA are presented in the Experiment 2 results section.
