• A. Edward Thorndike
• B. B.F. Skinner
• C. John B. Watson
• D. Ivan Pavlov

Answer: (A)

Understanding how consequences shape behavior is key here. Edward Thorndike pioneered the early ideas that would become operant conditioning. He showed, through puzzle-box experiments with cats, that actions followed by satisfying outcomes tend to be repeated, while those followed by dissatisfaction are less likely to recur—the law of effect. He also described the law of readiness, suggesting that learning happens best when an organism is prepared to act and the action sequence is directed toward a goal. The law of exercise adds that practice strengthens connections; the more a behavior is performed, the more likely it is to be repeated. Skinner later formalized the operant framework with detailed reinforcement schedules, but the foundational laws—effect, readiness, and exercise—are Thorndike’s work. Watson emphasized stimulus–response behavior in a broader sense, and Pavlov is famous for classical conditioning, not these operant-based laws.
