ABSTRACT
Many studies have shown that (a) functional communication training (FCT) is effective for reducing problem behavior, and (b) multiple schedules can facilitate reinforcer schedule thinning during FCT. Most studies tha have used multiple schedules with FCT have included therapist-arranged stimuli (e.g., colored cards) as the discriminative stimuli (S(D) s), but recently, researchers have evaluated similar multiple-schedule training procedures with naturally occurring S(D) s (e.g., overt therapist behavior). The purposes of the current study were to compare the effects of arranged and naturally occurring S(D) s directly during (a) acquisition of discriminated functional communication responses (FCRs) and (b) generalization of discriminated FCRs when we introduced the multiple schedules in novel contexts in which the naturally occurring stimuli were either relatively easy or difficult to discriminate. Results showed that (a) 2 of 3 participants acquired discriminated responding of the FCR more rapidly with arranged than with naturally occurring stimuli, (b) 2 of 3 participants showed resurgence of problem behavior , and (c) 2 of 3 participants showed greater generalization of discriminated responding to novel contexts with arranged stimuli than with naturally occurring stimuli. We discuss these results relative to the conditions under which naturally occurring and arranged S(D) s may promote rapid and generalized treatment gains.

We examined whether different durations of exposure to relevant establishing operations (EO) during treatment of problem behavior affected treatment efficacy and response bursting. In Study 1, we compared 2 functional communication training (FCT) interventions. In the first treatment, we used a card touch as the target mand; this was associated with limited exposure to the EO because we could physically guide the mand at prescribed times. In the other treatment, we used a vocal response as the mand; this was associated with longer exposure to the EO because it was not possible to guide the response. In Study 2, we exposed participants to time-based reinforcement schedules that were yoked to the schedules of obtained reinforcement from the 2 FCT interventions in Study 1. Results indicated that limited exposure to the EO was associated with less response bursting, larger and more rapid reductions in problem behavior, and faster acquisition of the alternative mand.

We examined relations between self-control responding and environmental variables with 3 children with behavior disorders. Differential delays were presented before or after task completion in a single-session reversal design. Delays presented before task completion produced more impulsive responding than those presented after task completion for all participants.
