The correct answer is Skinner.

B.F. Skinner, an American psychologist, is best known for his work in the field of behaviorism, particularly his theory of operant conditioning. This theory suggests that behavior is influenced significantly by the consequences that follow it. In operant conditioning, favorable consequences increase the likelihood of a behavior being repeated, while unfavorable consequences decrease it. Skinner utilized various devices, such as the Skinner Box, to experimentally demonstrate these principles, emphasizing that reinforcement and punishment are critical in shaping behavior. His contributions have significantly influenced education, psychology, and behavioral science, establishing him as a pivotal figure in understanding human and animal behavior.
