The current study describes the use of a procedure called the "potty party", an all-day toilet training method using basic learning principles of "errorless" discrimination with 3 children with incontinence diagnosed with autism. At the start of treatment days, each participant was greeted and prompted to request the bathroom. After the child requested the bathroom, they were taken to the restroom, pants and underpants were removed, the child was seated on the toilet. While on-seat, participants were given liquids, less-preferred reinforcers and engaged in typical daily activities such as discrete trial training. When the child voided in the toilet, specific verbal praise and highly preferred edible reinforcers were delivered. The child was also given time off the toilet with their most preferred toys or items/activities. Time off-toilet subsequently increased with each in-toilet urination until the participants were spending the same amount of time off-toilet, out-of-bathroom, and in the classroom as their peers. Results for all three participants using 3 non-concurrent A-B phase designs indicated that the potty party procedure was effective in decreasing accidents to zero levels for all three participants and increased in-toilet urination for two. Future directions for research in toileting are discussed.

The case of a 9-year-old male with autism spectrum disorder (ASD) who presented with problem behavior in the form of high-frequency clothing removal is reported. Descriptive data indicated the behavior occurred when tasks were presented and commonly delayed task demands and resulted in staff attention. Two latency functional analyses with isolated and synthesized contingencies were completed to clarify the operant function of the behavior. Initial results of the synthesized analysis indicated clothing removal was sensitive to attention and escape. However, a subsequent functional analysis with isolated contingencies indicated that the behavior was maintained only by attention. A function-based intervention package consisting of attention extinction, response blocking, and differential reinforcement of other behavior (DRO) effectively reduced the frequency of clothing removal to near-zero levels. Results of the intervention were partially generalized to a new therapist. The use of latency functional analyses as a means to rapidly examine isolated and synthesized contingencies maintaining problem behavior is discussed as well as the effects of the treatment package on the behavior of clothing removal.
