The provision of reinforcement to increase desired behaviors is a crucial element of behavior analytic intervention for individuals diagnosed with autism spectrum disorder (ASD). Formal preference assessments, like the multiple stimulus without replacement procedure (MSWO), are often used to determine reinforcers used during intervention. While…

The purpose of this study was to examine the effectiveness of two error correction (EC) procedures: modeling alone and the use of an error statement plus modeling. Utilizing an alternating treatments design nested into a multiple baseline design across participants, we sought to evaluate and compare the effects of these two EC procedures used to…

Individuals with low functioning autism spectrum disorders (LFASD) who demonstrate significant cognitive and communication needs benefit from using technology for learning graphic symbols for enhancing participation. This study investigated if an iPad application would increase identification of graphic symbols by children and adults with LFASD.…

This study describes the development and evaluation of a behavioral parent training protocol via telecommunication for three parents of preschool children with autism, with limited access to behavioral expertise. A single-subject, multiple baseline experimental design across child behaviors, replicated across parents, was used to evaluate the…

Today, the use of formal preference assessments, including paired-stimulus preference assessments, is widely utilized to help determine which items to use as reinforcers during intervention. A second way to determine potential reinforcers is to analyze multiple dimensions of a stimulus in the moment, a procedure known as in-the-moment reinforcer…

Self-instruction for individuals with an intellectual disability can be viewed as a pivotal skill in that once learned this skill has collateral effects on future behaviors in various environments. This study used a multiple probe across participants design to evaluate video modeling to teach high school students with an intellectual disability to…

West Syndrome is a severe, early-onset epilepsy syndrome, with significant implications for subsequent neurological and cognitive development. While most children with a prior diagnosis of West Syndrome initially follow a normal developmental trajectory, there is evidence of subsequent emergence of clusters of difficulties, including autism…

Students with disabilities trail behind their peers without disabilities while in school, as well as in post-secondary outcome areas. Given that self-determination and enhanced academic skills are associated with improved post-school outcomes, one possible solution is to identify interventions that teach self-determination and academic skills…

This research addresses the challenges of assessing receptive language abilities in minimally verbal children with autism spectrum disorder by comparing several adapted measurement tools: a standardized direct assessment of receptive vocabulary (i.e. Peabody Picture Vocabulary Test-4); caregiver report measures including scores on the Vineland-II…

Two students with developmental disabilities were taught two daily living skills using video prompting with error correction presented on an iPod Touch, and two different fading procedures were implemented. In one fading procedure, individual video clips were merged into multiple larger clips following acquisition of the entire skill. In the…

The article provides a set of tables with the differences necessary for statistical significance between the Vineland Adaptive Behavior Scales and Bayley Scales of Infant Development, McCarthy Scales of Children's Abilities, Stanford-Binet Intelligence Scale, and Wechsler scales. The tables are intended to supplement clinical decisions in…

Twenty-four children (ages 27-58 months) with autism were tested on the Bayley, Merrill-Palmer, and Vineland scales. While scores on the different tests were highly correlated, actual test scores varied considerably, with the Bayley tending to produce the lowest IQ scores and the Merrill-Palmer the highest. Implications for selecting pre- and…
