Whose research coined the term ‘operant conditioning’ to explain learning from consequences?

B. F. Skinner, an American psychologist, developed operant conditioning in the 1930s and 1940s. His work showed that actions followed by reinforcement are more likely to happen again, while behavior followed by punishment is less likely. He used controlled experiments, often with pigeons and rats, to study how consequences shape behavior. Skinner’s research became central to behaviorism and practical behavior modification.
