Do Adults Diagnosed With Autism Spectrum Disorders Have An Advantage In Real-World Visual Search Tasks?, Nicholas Charles Russell
Theses and Dissertations
Individuals with Autistic Spectrum Disorders (ASD) often perform better than typically developing (TD) individuals in simple, albeit difficult, visual search tasks. This ability is often attributed to a lack of drive for coherence or superior local processing. We compare thirty adults with ASD with forty-nine TD individuals and twenty-seven adults with anxiety (ANX) across two real-world visual search tasks. Individuals had to find either a number superimposed over a real-world scene ("œno context" condition) or an object located in a contextually relevant location ("œcontext" condition). Each participant completed forty-one trials in each condition, each with a unique scene. Eye movements …

The Relationship Between Auditory Habituation And Anxiety In Autism Spectrum Disorder, David Nicholas Top
Theses and Dissertations
Many individuals with autism spectrum disorder (ASD) have atypical sensory processing and behaviors including sensory sensitivity and low registration of sensory stimuli as well as sensory seeking and avoiding behaviors. Additionally, many individuals with ASD have clinically distressing levels of anxiety. Previous research suggests that there is a link between abnormal sensory processing, anxiety, and ASD. The purpose of this study was to experimentally observe auditory sensory processing using pupillometry methods, between ASD, control, and high-anxious control groups. While a difference in tonic pupil size was observed, there were no reactivity or habituation differences between the groups. There were no …
