Undiscriminated reinforcement contingency VS. Discriminated reinforcement contingency

Undiscriminated reinforcement contingency There is no sdee associated with the reinforcement contingency

Undiscriminated reinforcement contingency There is no sdee associated with the reinforcement contingency

Discriminated reinforcement contingency The reinforcement contingency is in operation only when the sdee is present, not when the sdelta is present. If a response is never reinforced, that is plain old extinction.
