Rats reached criterion for discriminated avoidance acquisition significantly faster under a 180-sec. than under a 30-sec. safebox confinement. Reversal (Exp. 1) and extinction (Exp. 2) of the original avoidance response were both facilitated by removal of either original safe or shock cues. No interaction was found between length of confinement in acquisition and safe- or shock-cue removal. The results were interpreted as only partially supporting an elicitation hypothesis of discriminated avoidance learning.
