Note: ABC = acquisition, extinction and testing all occurred in separate contexts; ABA = acquisition and testing occurred in the same context, but extinction of the CS occurred in a different context; CtxExt = context extinction treatment; X = Clicks; + = unconditioned stimulus presentation; − = no nominal stimulus presentation; A = Context A; B = Context B; C = Context C.
