Environment Experiment

Functional communication training (FCT) is used to reduce rates of problem behavior by teaching communicative responses that access functionally equivalent reinforcers. During FCT, the communicative response is typically placed on a dense schedule of reinforcement that is unlikely to be maintained in the natural environment. Experiment 1 evaluated the effects of two schedule-thinning procedures (chained schedules and multiple schedules) on problem behavior maintained by escape from demands for three participants following FCT. The chained and multiple-schedule procedures were effective in reducing rates of problem behavior. Compliance increased under both schedules, but the chained schedule resulted in higher levels of compliance with two participants. In Experiment 2, participants’ preference for the chained or multiple-schedule procedure was evaluated using a modified concurrent-chain procedure. One participant preferred the chained schedule. One participant preferred the multiple schedule. One participant did not appear to discriminate between conditions.

Schedule Performance

Performance of pigeons on a three component chained fixed interval schedule and a three component tandem fixed interval schedule was investigated as a function of reinforcement frequency in the terminal components. Stimuli in the chained schedule functioned as discriminative stimuli, demonstrated by absolute response rate differences between comparable chain and tandem schedule components. Absolute differences between chain and tandem response rates of the first two components were relatively invariant when reinforcement frequency in the terminal component was varied.

Chained Schedule

Pigeons peck faster during a signal for reward (S+) when that signal alternates with one for absence of reward (S−). This “contrast effect” has been shown to involve diminished preference for S + compared with a stimulus not involved in a discrimination. The present experiment demonstrates that the signal produced by pecks to S+ in a chained schedule is responded to in proportion to the contrast effect during S +. The result suggests that a prior interpretation of contrast, in terms of Amsel's frustration theory, is not the correct one.

Schedule Thinning

We treated destructive behavior maintained by both social-positive (i.e., access to tangibles) and social-negative (i.e., escape from demands) reinforcement in an individual diagnosed with autism spectrum disorder using functional communication training (FCT). We then thinned the schedule of reinforcement for the tangible function using a multiple schedule (mult FCT) and later thinned the availability of escape using a chained schedule (chain FCT). Both treatments proved effective at maintaining functional communicative responses while decreasing destructive behavior to near-zero levels. In addition, treatment effects maintained when we rapidly thinned mult FCT to the terminal schedule. Throughout chain-FCT schedule thinning, we assessed client preference for each schedule-thinning arrangement (mult FCT or chain FCT) using a concurrent-chains procedure. Client preference reliably shifted from chain FCT to mult FCT as the response requirement increased and the proportion of session spent in reinforcement began to favor mult FCT. We discuss the clinical implications of these findings.
