Final answer:
The statement that behavior therapists believe insight is not necessary for behavior change is true. They focus on behavior changes through environmental interactions and learning from reinforcements and consequences.
Step-by-step explanation:
The perspective of behavior therapists is anchored in the notion that changes in behavior can happen without the need for insight into one's psychological state or the underlying causes of the behavior. This view is indeed true according to the behavioral perspective in psychology. Behavior therapists, influenced by the work of B. F. Skinner and others who follow the behavioral school of thought, argue that behavior changes through interactions with the environment, and through learning from reinforcements and consequences, rather than through gaining deep insight.
Therefore, the statement that "Behavior therapists believe that insight is not a necessary condition for behavior change to occur" is True. They focus on observable behaviors and the external stimuli that can be manipulated to bring about change, rather than on internal mental states or insights.
Cognitive-behavioral therapists, on the other hand, integrate both cognitive processes and observed behaviors when providing therapy, suggesting a more holistic approach than traditional behaviorists.
