Abstract
Five male albino rats were trained on a DRL 15-sec schedule of reinforcement and injected with six doses of scopolamine hydrobromide. Analysis of the results by means of signal-detection theory indicated that the effects were due to modifications of stimulus sensitivity rather than changes in response bias. This was interpreted as evidence against a response-inhibition hypothesis and suggests that there were changes in the stimulus input.
