Skinner identified several ways to respond to behavior in order to increase or decrease the likelihood of that behavior being repeated. According to the article, what response types did Skinner identify? (Site 1)

Operant conditioning was coined by behavior psychologist B. F. Skinner.

Operant Conditioning is a system of three types of responses [punishment], [neutral operants], and [reinforcers] as a response to behaviors. Skinner found [neutral operant] responses from the environment neither increase nor decrease the probability of a behavior being repeated, [reinforcing] a behavior encourages its continuance, and [punishment] for a behavior encourages the end of the behavior.

Skinner is regarding as the father of Operant Conditioning, but his work was based on Thorndike's law of effect. According to this principal, consequence is likely to be repeated, and behavior followed by unpleasant consequences is less likely to be repeated.

Skinner introduced a new term into the Law of Effect - Reinforcement. Behavior which is reinforced tends to be repeated; behavior which is not reinforced tends to die out-or be extinguished.

Skinner studied Operant Conditioning by conducting experiments using animals which he placed in a 'Skinner Box' which was similar to Thorndike's puzzle box.
