The responses of white rats were maintained on an unsignalled free‐operant avoidance schedule. Superimposed on the avoidance schedule was a blinking white light followed immediately by response‐independent electric shock. Duration of the light stimulus was either 1 or 3 min. Avoidable shock was 1.5 mA; response‐independent shock was 7.5 mA. Suppression of responding during the light stimulus (both durations) developed over sessions. Responding immediately following the response‐independent light‐shock sequence was neither suppressed nor accelerated. The similarity is noted between the present result and findings of “positive conditioned suppression”.
