Background: People with severe-to-profound intellectual disabilities often lack meaningful interactions with others. Communication partners need to be skilled in identifying and responding to often-subtle behaviours. One method of facilitating interaction is the use of sensory-based stimuli. Method: This study measured the impact of sensory-based…

This triple-arm, double-blind, randomized clinical trial investigated the effect of multisession prefrontal transcranial direct current stimulation (tDCS) on social functioning in individuals with autism spectrum disorder (ASD). A total of 105 individuals (age 14-21 years) diagnosed with ASD were randomized into the active-tDCS, sham-tDCS, and…

The Good Behavior Game (GBG) is an effective intervention to reduce disruptive behavior. The GBG typically involves immediate stimulus presentation (e.g., delivery of a token) following disruptions; however, experimenters have also removed tokens contingent upon disruptions. In the present study, we compared the effects of the GBG-stimulus…

The school-based consultation literature includes a variety of empirically supported procedures for increasing teachers' implementation of classroom management strategies. However, teachers may respond differently to empirically supported consultation procedures. This study used a multiple baseline design across three elementary teachers to test…

The present study aimed to develop a proposed training program based on DTT to improve the nonverbal communication skills in children with ASD. To achieve the objective of the study, the author developed a scale of non-verbal communication skills consisted of (20 items) measures attention and eye contact, imitation and using the signal,…

This study compared the efficacy of no choice and choice of preferred engagement stimuli to reduce escape-maintained disruptive behavior of pupils in kindergarten with developmental disabilities in inclusive classes. This study demonstrated how functional behavior assessment can be conducted in a school setting to determine the functional…

Effectively managing a classroom is crucial in promoting positive student outcomes. Behavior-specific praise is an empirically supported strategy to reinforce desirable student behaviors. Following a review of the literature, we identified tactile prompting and self-monitoring as effective methods to increase teachers' use of behavior-specific…

We evaluated functional communication training (FCT) combined with a chained schedule of reinforcement procedure for the treatment of challenging behavior exhibited by two individuals diagnosed with Asperger syndrome and autism. Following functional analyses that suggested that challenging behavior served multiple functions for both participants,…

There is a lack of evidence-based behavioral therapies or pharmacotherapies to treat repetitive behaviors found in autism. Effective behavioral therapies are needed to counter any negative consequences these behaviors may have on the child's early learning and socialization. The purpose of this proof-of-principle study was to test the feasibility…

Training context can influence resistance to disruption under differing reinforcement schedules. With nonhumans, when relatively lean and rich reinforcement schedules are experienced in the context of a multiple schedule, greater resistance is found in the rich than the lean component, as described by behavioral momentum theory. By contrast, when…

The effects of a pica exchange procedure were evaluated on the pica of a female with severe mental retardation. A BAB design revealed that the pica exchange procedure was effective at reducing the occurrence of pica. In addition, the pica exchange procedure was effective throughout six increasingly more difficult response effort conditions.…

A functional analysis suggested that rumination exhibited by an adult with autism was maintained by automatic reinforcement. Next, a preference assessment with three flavor sprays (i.e., flavored sprays used by dieters) showed that apple pie spray was most preferred. Finally, the effects of fixed-time delivery of the apple pie spray on levels of…

One child with developmental disabilities was taught to mand for attention by saying "excuse me." Treatment effects were extended to multiple training contexts by teaching the participant to attend to naturally occurring discriminative stimuli through differential reinforcement of communication during periods of the experimenter's nonbusy…

Two children with developmental delays and a history of problem behavior participated in this study to examine the efficacy of combining two treatments demonstrated to reduce problem behavior: noncontingent reinforcement and functional communication training. At issue was whether the noncontingent delivery of an alternative preferred stimulus and…
