Final answer:
There is no record of a Munstberg contributing to Early Behaviorism; the question likely refers to key figures like Pavlov, Watson, and Skinner. They developed the foundations of behaviorism, which shifted psychology's focus to observable behavior, measurable experiments, and away from internal mental processes.
Step-by-step explanation:
The contribution of Munstberg to Early Behaviorism seems to be a typographical error, as there is no prominent figure by that name associated with the development of behaviorism. However, discussing behaviorism's contributions brings to attention key figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner, among others.
Pavlov's pioneering work with classical conditioning laid the foundation for behaviorism, demonstrating how organisms can develop a conditioned response to previously neutral stimuli. Watson, often regarded as the founder of behaviorism, built on Pavlov's findings, advocating a scientific approach to psychology focused exclusively on observable behaviors rather than internal experiences.
Skinner further developed behaviorism with his concept of operant conditioning, emphasizing reinforcement and punishment as key factors in behavior change.
Behaviorism's significance in psychology was to move the field toward a more empirical and measurable scientific basis, shifting the focus from internal mental processes to observable behavior. This approach was highly influential during the first part of the 20th century, until the cognitive revolution, led in part by Noam Chomsky, prompted a reintegration of mental processes into psychological research.
