Dissertations - ALL

This study examined factorial invariance of three self-report measures of psychiatric symptoms—the World Health Organization Adult ADHD Self-Report Scale (ASRS; Kessler et al., 2005), the Center for Epidemiologic Studies Depression Scale-Revised (CESD-R; Eaton, Smith, Ybarra, Muntaner, & Tien, 2004), and the Depression Anxiety Stress Scales (DASS; Lovibond & Lovibond, 1995)—using a convenience sample of 434 adults surveyed though Amazon Mechanical Turk. Participants were sorted into two groups based on their score on the Autism-Spectrum Quotient (AQ; Baron-Cohen, Wheelwright, Skinner, Martin, & Clubley, 2001). Of 423 participants included in the final sample, 203 were included in the low ASD traits group …

Visual Processing Across Space And Time In Children With Autism Spectrum Disorder, Justin Kopec

Dissertations - ALL

Individuals with autism spectrum disorder (ASD) demonstrate enhanced perceptual

abilities relative to typically developing (TD) peers, as evidenced by better detection and identification of visual targets. This enhanced ability to discriminate features has been replicated across spatial and temporal displays. Research also suggests that visual perceptual abilities are correlated with the severity of core autism symptoms in this population, with the exception of atypical sensory behaviors, including sensory seeking and aversion, in which the relationship has been understudied and remains poorly understood. The current study introduces a novel visual search task to assess identification accuracy of feature-based visual targets that …
