A LINC digital computer was used to generate an autoregressive schedule of reinforcement. On such a schedule the probability of reinforcement is a function of the similarity in duration of the intervals between successive responses. A detailed analysis of the data obtained from monkeys on this schedule demonstrated two distinct tendencies in their behavior: a tendency for periodic response and a tendency for serial dependence between successive interresponse times.
