Luckhardt, Christina; Kröger, Anne; Cholemkery, Hannah; Bender, Stephan; Freitag, Christine M. – Journal of Autism and Developmental Disorders, 2017
The underlying neural mechanisms of implicit and explicit facial emotion recognition (FER) were studied in children and adolescents with autism spectrum disorder (ASD) compared to matched typically developing controls (TDC). EEG was obtained from N = 21 ASD and N = 16 TDC. Task performance, visual (P100, N170) and cognitive (late positive…

Herrington, John D.; Riley, Meghan E.; Grupe, Daniel W.; Schultz, Robert T. – Journal of Autism and Developmental Disorders, 2015
This study examines whether deficits in visual information processing in autism-spectrum disorder (ASD) can be offset by the recruitment of brain structures involved in selective attention. During functional MRI, 12 children with ASD and 19 control participants completed a selective attention one-back task in which images of faces and houses were…

Tseng, Angela; Bansal, Ravi; Liu, Jun; Gerber, Andrew J.; Goh, Suzanne; Posner, Jonathan; Colibazzi, Tiziano; Algermissen, Molly; Chiang, I-Chin; Russell, James A.; Peterson, Bradley S. – Journal of Autism and Developmental Disorders, 2014
The Affective Circumplex Model holds that emotions can be described as linear combinations of two underlying, independent neurophysiological systems (arousal, valence). Given research suggesting individuals with autism spectrum disorders (ASD) have difficulty processing emotions, we used the circumplex model to compare how individuals with ASD and…

Pearson, Amy; Marsh, Lauren; Hamilton, Antonia; Ropar, Danielle – Journal of Autism and Developmental Disorders, 2014
Previous research into autism spectrum disorder (ASD) has shown people with autism to be impaired at visual perspective taking. However it is still unclear to what extent the spatial mechanisms underlying this ability contribute to these difficulties. In the current experiment we examine spatial transformations in adults with ASD and typical…

Dundas, Eva M.; Best, Catherine A.; Minshew, Nancy J.; Strauss, Mark S. – Journal of Autism and Developmental Disorders, 2012
It has been established that typically developing individuals have a bias to attend to facial information in the left visual field (LVF) more than in the right visual field. This bias is thought to arise from the right hemisphere's advantage for processing facial information, with evidence suggesting it to be driven by the configural demands of…

Strauss, Mark S.; Newell, Lisa C.; Best, Catherine A.; Hannigen, Sarah F.; Gastgeb, Holly Zajac; Giovannelli, Joyce L. – Journal of Autism and Developmental Disorders, 2012
While much research has examined the development of facial recognition abilities, less is known about the ability of individuals with and without autism to categorize facial gender. The current study tested gender categorization abilities in high-functioning children (5-7 and 8-12 years), adolescents (13-17 years), and adults (18-53 years) with…

Dundas, Eva; Gastgeb, Holly; Strauss, Mark S. – Journal of Autism and Developmental Disorders, 2012
While it is well-known that individuals with autism spectrum disorder (ASD) have difficulties processing faces, very little is known about the origins of these deficits. The current study focused on 6- and 11-month-old infants who were at either high-risk (n = 43) or low-risk (n = 31) for developing ASD based on having a sibling already diagnosed…

Mazefsky, Carla A.; Oswald, Donald P. – Journal of Autism and Developmental Disorders, 2007
This study compared emotion perception accuracy between children with Asperger's syndrome (AS) and high-functioning autism (HFA). Thirty children were diagnosed with AS or HFA based on empirically supported diagnostic criteria and administered an emotion perception test consisting of facial expressions and tone of voice cues that varied in…

Webb, Sara J.; Dawson, Geraldine; Bernier, Raphael; Panagiotides, Heracles – Journal of Autism and Developmental Disorders, 2006
Autism involves a basic impairment in social cognition. This study investigated early stage face processing in young children with autism by examining the face-sensitive early negative event-related brain potential component in 3-4 year old children with autism spectrum disorder (ASD), typical development, and developmental delay. Results…

Peterson, Candida C. – Journal of Autism and Developmental Disorders, 2005
This study examined theory of mind (ToM) and concepts of human biology (eyes, heart, brain, lungs and mind) in a sample of 67 children, including 25 high functioning children with autism (age 6-13), plus age-matched and preschool comparison groups. Contrary to Baron-Cohen [1989, "Journal of Autism and Developmental Disorders," 19(4),…
