Final answer:
It is true that variation in therapy settings and stimuli can facilitate generalization according to the principles of behaviorism.
Step-by-step explanation:
True, instructors can help facilitate generalization by varying the therapy setting, SDs (discriminative stimuli), and other stimuli. This is based on the principles of behaviorism, a school of thought which focuses on observable behavior rather than internal mental processes. According to behaviorist theory, generalization occurs when an organism demonstrates the conditioned response to stimuli that are similar to the conditioned stimulus. By varying different aspects of the learning environment, an organism can generalize the learned behavior to new situations, settings, or stimuli. This is opposite to stimulus discrimination, where an organism learns to respond differently to various similar stimuli.
