Final answer:
Behavioristic theory's emphasis on measurable and observable facts is true, as it looks at how environmental factors shape behavior through reinforcements and consequences according to B. F. Skinner and John Watson.
Step-by-step explanation:
Behavioristic theory is most noted for its emphasis upon measurable and observable facts is true. Behaviorists, such as B. F. Skinner, focused on observable behaviors rather than unobservable mental processes and believed that the environment is solely responsible for all behavior. This perspective is grounded in the notion that personality is significantly shaped by external reinforcements and consequences, and is aligned with the push for psychology to be an objective science.
John Watson, often considered the father of behaviorism, and B. F. Skinner's work on operant conditioning, placed importance on overt behavior and sought to establish psychology as a discipline grounded in objectivity. This shift towards observable phenomena over subjective introspection differentiated behaviorism from previous psychological theories.
