Operant conditioning
Consequences alter the future probability of actions in a context.
Theory The classification describes how this account is used here; it is not an evidence rating.
Central claim
Voluntary actions become more or less probable in a given context depending on the consequences that follow them. Reinforcement strengthens the behavior it follows, whereas punishment weakens it.
Proposed mechanism
Reinforcement increases an action and punishment decreases it. Positive and negative describe adding or removing an event. Whether an event is a reinforcer is determined by its behavioral effect, not by the giver's intention.
Evidence: (Spielman et al., 2020)
What would it predict?
Hold opportunities to respond constant and make an outcome contingent on one action. If the action subsequently increases, the outcome functioned as reinforcement in those conditions.
An original test formulation derived from the account, not a claim that this exact study was performed.
Evidence and status
Thorndike (1911) formulated the law of effect from puzzle-box studies, which informed Skinner's (1938, 1953) systematic operant-chamber research. Schedule experiments described in the textbook compare response rates and extinction resistance under different reinforcement arrangements.
Evidence: (Spielman et al., 2020)

Edward Thorndike; B. F. Skinner; many experimental behavior analysts

Apply the explanation
Original teaching scenario
A student checks practice answers more often after checking reliably produces useful feedback. Increased checking, not praise alone, identifies the reinforcing effect.
Constructed for learning. This scenario does not report an empirical result.
Common confusion: Classical conditioning or punishment as negative reinforcement
Operant conditioning depends on consequences contingent on an action rather than passive cue pairing, and negative reinforcement removes an aversive condition to increase behavior rather than punishing it.

Limits and alternatives
- A reward is not automatically a reinforcer. Changes in motivation, competing actions, instructions and context complicate generalization from a chamber to a classroom.
