renforcement irrégulier

CONT: This assumption may be checked by constructing a schedule of reinforcement in which a differential contingency between rate of responding and reinforcement is impossible. In one such schedule of what may be called ""aperiodic reinforcement"" one interval between successive reinforced responses is so short that no unreinforced responses intervene while the longest interval is about two minutes. Other intervals are distributed arithmetically between these values, the average remaining one minute. The intervals are roughly randomized to compose a program of reinforcement.
