Final answer:
Peak shift is the term used to describe a change in maximal generalization responding away from SΔ to the other side of SD.
Step-by-step explanation:
The correct answer is B) Peak shift. This term refers to a change in maximal generalization responding, where the response shifts away from the stimulus delta (SΔ) and towards the other side of the discriminative stimulus (SD). In other words, it is when the individual responds more strongly to stimuli that are further away from the original stimulus that was used during training.
