The dog's ability to distinguish between the circle (which has been associated with meat) and the oval (which has not) and only salivate to the circle is an example of stimulus discrimination. This means the dog has learned to respond differently to two stimuli based on their differences, indicating it can discriminate between the circle that predicts food and the oval that does not.
