Here is a summary of the provided Wikipedia article on Psychological Behaviorism:

Psychological behaviorism, proposed by Arthur W. Staats, is a comprehensive theory designed to explain all types of human behavior, ranging from basic learning to personality and culture. Unlike earlier forms of behaviorism by pioneers like John B. Watson (who coined "behaviorism" in 1912) and B. F. Skinner, which primarily relied on animal research and rejected introspection, Staats uniquely conducted his studies with human subjects. He integrated basic animal learning principles with specific human learning principles, leading to a broader, more unified understanding of psychology, as noted by Warren Tryon (2004).

A core distinction in Staats' theory is that classical and operant conditioning are not separate but interact profoundly. For Staats, emotion stimuli, learned through classical conditioning, play a central role as causes of behavior. These emotion stimuli not only elicit emotional responses but also function as reinforcers, punishers, and discriminative stimuli within operant conditioning, making emotion foundational to his framework.
