Summary
Rats were trained to discriminate response produced cues in one component of a multiple schedule and the onset of a clicker in the other component. The response requirements were identical. Scopolamine intoxication resulted in a deterioration of the interoceptive cue discrimination and an improvement in the discrimination of the exteroceptive stimuli.
