ABSTRACT
The present study investigated the effects of differential negative reinforcement of other behavior (DNRO) on problem behavior evoked by music in a 7-year-old child with pervasive developmental disorder. Following an auditory stimulus assessment, DNRO was used to reduce problem behavior to near-zero levels. Results are discussed in terms of identifying establishing operations to govern treatment options and the use of negative reinforcement when arbitrarily imposed positive reinforcers do not compete with escape from auditory stimulation.

We evaluated the effects of multiple treatment procedures, including simultaneous presentation of preferred foods, on the packing behavior of a 9-year-old girl with autism. A reversal design was used to assess the effects of differential reinforcement with response cost alone and with simultaneous presentation. In addition, simultaneous presentation was assessed independent of differential reinforcement with response cost. Results indicated that simultaneous presentation reduced packing and that differential reinforcement with response cost was not necessary to maintain these reductions. Results are discussed in terms of the use of simultaneous presentation for packing as an alternative to consequence manipulations.

We investigated the effects of response effort on the use of mands during functional communication training (FCT) in a participant with autism. The number of links in a picture exchange response chain determined two levels of response effort. Each level was paired with a fixed ratio (FR3) schedule of reinforcement for aggression in a reversal design. Responding to either schedule produced access to a preferred item. The participant opted for the low effort mand while aggression decreased significantly. However, the high effort mand did not compete with the FR3 schedule for aggression. Results are discussed in terms of response effort within a response chain of a picture exchange system and competing ratio schedules for problem behavior during mand training.
