Simultaneous prompting is an errorless learning strategy designed to reduce the number of errors students make; however, research has shown a disparity in the number of errors students make during instructional versus probe trials. This study directly examined the effects of error correction versus no error correction during probe trials on the…

This study aimed to evaluate the effects of cueing in visual search paradigm for people with and without intellectual disabilities (ID). A total of 36 subjects (18 persons with ID and 18 persons with normal intelligence) were recruited using convenient sampling method. A series of experiments were conducted to compare guided cue strategies using…

This study aimed to examine the use of a predictive stimulus (Time Timer[TM]) and delayed reinforcement to increase appropriate waiting behavior in a child with developmental disabilities and problem behavior maintained by access to tangible items and activities. The study employed a changing criterion design across settings to gradually increase…

We evaluated the efficacy of a vocational training program including behavioral skills training, and a "performance cue system" (i.e., a proprietary iPhone application adapted for the study) to teach targeted social-vocational skills to six young adults with an Autism Spectrum Disorder. In two separate studies, participants were employed…

We evaluated a video-based error correction procedure for teaching four adults with developmental disabilities to set a table. Video clips were initially used as an antecedent prompt. However, only one of the adults learned to set the table with this procedure. Consequently, the remaining three adults received intervention in which the video clips…
