![]() Visual perception and perceptual performance in ASD thus may not be simply labeled as diminished or “impaired” global processing. Research in typically developing individuals or healthy adults suggests that there is also natural variability in perceptual precedence across the general population ( Scherf et al., 2009 Dale and Arnell, 2010 McKone et al., 2010). However, a large proportion of the current research utilizes specific perceptual paradigms designed to capture differences in global/local processing (i.e., Navon figures EFT, Embedded figures test) and makes direct comparisons between those with ASD diagnoses and those that lack any diagnosis ( Plaisted et al., 1998 O'Riordan et al., 2001 Dakin and Frith, 2005 Mottron et al., 2006 Scherf et al., 2008 Kaldy et al., 2011, 2016). ![]() Inconsistent results across the current literature have been attributed to variable sample demographics and the clinical characterization of diagnostic groups, variable task demands, differences in task administration, and differing stimulus properties ( Van der Hallen et al., 2015). local processing ( Happé and Booth, 2008). While some reports indicate poorer task performance on paradigms requiring global visual processing in individuals with ASD as compared to their peers, others have been unable to identify significant differences in perceptual precedence or global vs. However, other studies have noted that enhanced perceptual performance in individuals with ASD may not be observed across all contexts ( D'Souza et al., 2016 Guy et al., 2019). Several studies have demonstrated a perceptual bias to local as compared to global features and/or enhanced visual processing abilities in individuals with ASD ( Happé, 1999 Dakin and Frith, 2005 see Simmons et al., 2009 for review). Visual perception has been researched at length in autism spectrum disorder (ASD). Findings presented here suggest variability in perceptual processing across ASD may be influenced by individual differences in trait distribution. Additionally, results of an item-level analysis point to a significant relationship between within-task variability on the Figure Ground subtest and quantitative ASD traits, with a less variable response pattern being associated with increased ASD symptoms. We report a significant linear relationship between ASD features and performance on the TVPS Figure Ground subtest. In addition to assessing overall accuracy across subtests of the TVPS, we also assessed response variability at the item-level, and the linear relationship between quantitative measures of ASD symptoms, task performance, and item-level variance. The purpose of the current study was to assess meaningful variability in visual-perceptual skills using a standardized assessment of visual perception, the Test of Visual Perceptual Skills (TVPS), across children with and without autism spectrum disorder (ASD). 4Department of Basic Sciences, Geisinger Commonwealth School of Medicine, Scranton, PA, United States.3Geisinger Neuroscience Institute, Danville, PA, United States.2Department of Imaging Science and Innovation, Center for Health Research, Danville, PA, United States.1Geisinger Health System, Autism and Developmental Medicine Institute (ADMI), Lewisburg, PA, United States.Antoinette Sabatino DiCriscio 1 *, Jaclyn Smith 1 and Vanessa Troiani 1,2,3,4
