Quizplus · Accepted Answer

Peak shift is primarily observed in successive discrimination tasks, where an animal is trained to respond to a certain stimulus and then presented with stimuli that are gradually more and more different. In such tasks, the animal’s responses tend to shift further away from the original stimulus, resulting in a “peak” response to a stimulus that is even more different than the last one presented. While peak shift can occur in simultaneous discrimination tasks as well, it is not as commonly observed in that context.
