Stimulus equivalence training has been relatively under represented in the research literature for training individuals with autism spectrum disorder (ASD) in early letter-sound correspondence. The primary purpose of the current study was to compare the effectiveness of two different topographies of intraverbals on the emergence of untrained…

The purpose of the present study was to evaluate the effects of multiple exemplar training and social reinforcement on the maintenance and generalization of joint attention initiations across toy classes. Three children with autism spectrum disorder (ASD) participated. After analyzing samples of joint attention initiations from neurotypical peers,…

The relationships of autism quotient (AQ), systematizing (SQ), and empathizing (EQ), with over-selectivity were explored to assess whether over-selectivity is implicated in complex social skills, which has been assumed, but not experimentally examined. Eighty participants (aged 18-60) were trained on a simultaneous discrimination task (AB+CD-),…

The present study evaluated the emergence of intraverbal responses following tact training with three adolescents diagnosed with autism spectrum disorders. Participants were taught to tact the name of a cartoon character (e.g., "What is the name of this monster?" ["Simon"]) and that character's preferred food (e.g., "What food does this monster…

Individuals with autism spectrum disorders (ASDs) have been assumed to show evidence of abnormal visuospatial processing, which has been attributed to a failure to integrate local features into coherent global Gestalts and/or to a bias towards local processing. As the available data are based on baseline performance only, which does not provide…

A critical component of effective communication is the ability to consider the knowledge state of one's audience, yet individuals with autism spectrum disorders (ASD) have difficulty representing the mental states of others. In the present study, youth with high-functioning ASD were trained to consider their reader's knowledge states in…

The effect of expertise training with faces was studied in adults with ASD who showed initial impairment in face recognition. Participants were randomly assigned to a computerized training program involving either faces or houses. Pre- and post-testing included standardized and experimental measures of behavior and event-related brain potentials…

Four autistic children, age 8-15, exhibited fewer correct responses to a stimulus as the number of stimulus components was increased from 1 to 4. Training was effective in producing some generalized increases in responses to complex stimuli. (Author/JDD)
