This study used an adapted alternating treatments design to compare the effectiveness of two different procedures for fading video prompts for teaching two individuals with developmental disabilities and moderate intellectual disability to independently perform two different daily living tasks. The tasks were systematically faded from video…

Purpose: This study investigated the effects of signs on word learning by children with developmental language disorder (DLD), in comparison with typically developing (TD) children, and the relation between a possible sign effect and children's linguistic and cognitive abilities. Method: Nine- to 11-year-old children with DLD (n = 40) and TD…

Recent research has shown the effectiveness of literacy-based behavioral interventions (LBBIs) as an instructional strategy for a host of skills and routines, including employment skills. This study compared the effects of three LBBI storybook formats (print, e-book, and e-book enhanced with video clips) on the accuracy and independent completion…

Few published studies have systematically compared the efficacy of different prompt-fading methods in the training of complex response chains. The current study systematically compared a most-to-least physical prompt fading hierarchy with a most-to-least vocal prompt fading strategy in the training of four arbitrary Tinkertoy® construction tasks…

The ability to engage in positive social interactions is an important goal for young children with developmental disabilities (DDs). Peer-mediated intervention (PMI), one category of interventions often employed with those who show social skill deficits, involves use of typical peers who live model appropriate behaviors. A second frequent category…

This study examined the efficacy of the EDIT Strategy on proofreading skills of postsecondary individuals who attended a campus-based college program for students with developmental disabilities. A random assignment to treatment or control groups and a pre- and posttest with maintenance follow-up design were employed. The EDIT Strategy was taught…

The present study compared a spelling practice intervention using a tablet personal computer (PC) and picture cards with three students diagnosed with developmental disabilities. An alternating-treatments design with a non-concurrent multiple-baseline across participants was used. The aims of the present study were: (a) to determine if…

This study evaluated two methods of training staff who were working with individuals with developmental disabilities: pyramidal training and consultant-led training. In the pyramidal training, supervisors were trained in the principles of applied behavior analysis (ABA) and in delivering feedback. The supervisors then trained their direct-care…

This study used an iPod Touch to compare the effects of video prompting with and without error correction on the acquisition of two daily living skills across three students with moderate to profound intellectual disability and an extremely limited daily living skills repertoire. An adapted alternating treatments design within a multiple probe…

The purpose of this study was to compare the effects of simultaneous prompting instruction with high and low treatment integrity on the learning of children with developmental disabilities. Low treatment integrity was defined as not delivering a controlling prompt during 30% of the teaching trials. Three preschool children with autism and…

There is limited research demonstrating direct instruction (DI) as an effective language intervention for students with autism spectrum disorders (ASD) and developmental disabilities (DD). Existing research has shown that instruction using partial implementation of DI programs resulted in student learning (Ganz, 2007) and instruction using whole…

This study compared the effectiveness of self-, other-, and subjective-video models on teaching daily living skills to three individuals with developmental disabilities. Results indicated that all conditions were effective in promoting independent correct responding in both instructional and generalization settings and that the effects maintained…

Numerous instructional techniques have been used to teach sight word reading skills to individuals with developmental disabilities. The results of research incorporating paired associate instruction, in which familiar pictures are paired with unknown print stimuli, suggest that pictures ''block'' (i.e., interfere with) learners' ability to…

We compared two procedures (video prompting versus video modeling) for teaching six adults with developmental disabilities to set a table and put away groceries. Video prompting involved 10 separate video clips, each showing one step of the task analysis. Video modeling involved a single video showing all 10 steps from beginning to end. After…

A single subject alternating treatment design was used to compare the effectiveness of embedded and small-group instruction to teach vocabulary word definitions to four middle school students with developmental disabilities. Embedded instruction was implemented in the students' general education classes. Students were taught to verbally define…
