Final answer:
Behavior from the perspective of radical behaviorism is shaped by the environment and external factors, with a focus on observable behavior and the role of reinforcement and consequences.
Step-by-step explanation:
From the perspective of radical behaviorism, behavior is viewed as being shaped by the environment and external factors rather than inborn traits. B.F. Skinner, a key figure in radical behaviorism, believed that all behavior, including complex mental functions like language, can be understood as stimulus-outcome associations. This perspective focuses on studying observable behavior and emphasizes the role of reinforcement and consequences in shaping behavior.
