Skinner is one of the primary figure in psychology, he critiqued the concept of free will, Suggesting that environmental factors are large shaped the human behavior through conditioning. According to Skinner people have a "choices" which is response to past reinforcement and punishment patterns. I personally really like Skinner's theory since my first year, for me it's so interesting and very insightful. As a student I see teachers daily perform this daily with students, as a students I know what action I need to repeat to get praise or rewards.
