Following Functional Communication Training (FCT), clinicians often gradually expose newly taught communicative responses to delayed reinforcement contingencies to prepare clients for the normative environment in which requests are frequently reinforced after a delay. The introduction of delays may result in the resurgence and maintenance of problem behavior and the weakening of the newly trained communicative response. The current study compared delay tolerance with three individuals diagnosed with intellectual and developmental disabilities when reinforcement for the functional communication response (FCR) was delivered following (a) the passage of time, (b) the omission of problem behavior, or (c) the occurrence of an alternative behavior. We measured delay tolerance in terms of minimizing problem behavior and maintaining efficient FCRs. Outcomes support requiring alternative responding during delays to attain optimal treatment results.

Children of both typical and atypical cognitive development tend to prefer contexts in which their behavior results in a choice of reinforcers rather than a single reinforcer, even when the reinforcer accessed is identical across conditions. The origin of this preference has been attributed speculatively to behavioral histories in which choice making tends to be associated with differentially beneficial outcomes. Few studies have evaluated this claim, and those that have, have yielded mixed results. We provided five preschool‐aged children experiences in which choice‐making and no‐choice contexts were differentially associated with higher preference and larger magnitude reinforcers, and we assessed changes in their preference for choice and no‐choice contexts in which outcomes were equated. These conditioning experiences resulted in consistent and replicable shifts in child preference, indicating that preference for choice is malleable through experience.
