Changes in Unsignalled Avoidance Behavior When a Pre-Shock CS is Response-Produced

Six rat Ss were trained under a procedure in which signalled shock (CS-US) was superimposed on unsignalled avoidance behavior. The US was delivered for 1⁄4 sec. for three is (Condition S) and given for I sec. to three Ss (Condition L). Then, while the CS-US procedure was maintained, at different times during the session a response briefly produced the pre-shock CS. Blocks of sessions in which the response-produced CS occurred in addition to CS-US were alternated with blocks of CS-US sessions without the response-produced CS. Under the CS-US procedure, avoidance in CS was enhanced for Ss in Condition S and was enhanced to a lesser degree during the response-produced CS. On the other hand, the CS controlled suppressed avoidance when followed by US and when response-produced
