Children with autism spectrum disorder (ASD) are taught conditional discriminations often during early intervention. Auditory-visual conditional discrimination (AVCD) training requires the presentation of multiple antecedent stimuli, and the order of stimulus presentation varies in the literature. This series of studies replicated previous…

To date, studies have not established whether autistic and non-autistic individuals differ in emotion recognition from facial motion cues when matched in terms of alexithymia. Here, autistic and non-autistic adults (N = 60) matched on age, gender, non-verbal reasoning ability and alexithymia, completed an emotion recognition task, which employed…

Auditory-visual conditional discrimination training (e.g., receptive identification training, listener responses; AVCD) is ubiquitous in early intervention and special education programs. Nevertheless, some learners with Autism Spectrum Disorder (ASD) do not appear to benefit from this training despite use of empirically validated treatments. To…

Children with autism spectrum disorder are typically taught conditional discriminations using a match-to-sample arrangement. Consideration should be given to the temporal order in which antecedent stimuli (the sample and comparison stimuli) are presented during match-to-sample trials, as various arrangements have been used in the extant…

Individuals with autism spectrum disorder (ASD) show atypical processing of facial expressions. Research with autistic toddlers suggests that abnormalities in processing of spatial frequencies (SFs) contribute to such differences. The current event-related-potential (ERP) study investigated differences between 10-month-old infants with high- and…

Few studies have evaluated the use of assessment to identify the most efficient instructional practices for individuals with autism spectrum disorder. This is problematic as these individuals often have difficulty acquiring skills, and the procedures that may be efficient with one individual may not be for others. The experimenters conducted…

"Stimulus over-selectivity" describes a phenomenon in which an individual responds only to a subset of the stimuli present in the environment and, thus, may restrict learning. This study aimed to develop understanding of the nature and role of over-selectivity in autism spectrum disorder (ASD) by analyzing the relationship of…

Children who are diagnosed with autism spectrum disorder (ASD) often fail to show equivalence class formation. This may be related to their difficulty in learning the programmed baseline conditional discriminations. The present study investigated equivalence class formation after training visual identity-matching performance with auditory…

In teaching conditional discriminations to children with autism spectrum disorder (ASD), practitioners may progress from simple to conditional discriminations or may teach conditional discriminations from the onset of instruction. Some research indicates that teaching simple discriminations first may be unnecessary and that teaching may more…

This study examined if listener behavior and responding by exclusion would emerge after training 3 participants with autism to tact stimuli. Tacts for 2 of 3 stimuli were directly trained using discrete trial training methodology and were followed by an auditory-visual discrimination probe in which auditory-visual discrimination by naming (i.e.,…

Autistic individuals often present atypicalities in adaptation--the continuous recalibration of perceptual systems driven by recent sensory experiences. Here, we examined such atypicalities in human biological motion. We used a dual-task paradigm, including a running-speed discrimination task ('comparing the speed of two running silhouettes') and…

We extended past observational learning research by incorporating stimuli already known to participants into training. We used a multiple-baseline design across three participants to determine the effects of discrimination training on the discrimination of consequences applied to modeled responses using both known and unknown pictures. During…

Individuals with Autism Spectrum Disorder (ASD) often excel on visual search and crowding tasks; however, inconsistent findings suggest that this 'islet of ability' may not be characteristic of the entire spectrum. We examined whether performance on these tasks changed as a function of motor proficiency in children with varying levels of ASD…

There has been an increased interest in research evaluating the use of handheld computing technology as speech-generating devices (SGD) for children with autism. However, given the reliance on single-subject research methodology, replications of these investigations are necessary. This study presents a replication with variation, of a method for…

The eye-tracking experiment was carried out to assess fixation duration and scan paths that individuals with and without high-functioning autism spectrum disorders employed when identifying simple and complex emotions. Participants viewed human photos of facial expressions and decided on the identification of emotion, the negative-positive emotion…
