Children with Autism Detect Targets at Very Rapid Presentation Rates with Similar Accuracy as Adults
Peer reviewed Peer reviewed
Direct linkDirect link
Hagmann, Carl Erick; Wyble, Bradley; Shea, Nicole; LeBlanc, Megan; Kates, Wendy R.; Russo, Natalie – Journal of Autism and Developmental Disorders, 2016
Enhanced perception may allow for visual search superiority by individuals with Autism Spectrum Disorder (ASD), but does it occur over time? We tested high-functioning children with ASD, typically developing (TD) children, and TD adults in two tasks at three presentation rates (50, 83.3, and 116.7 ms/item) using rapid serial visual presentation.…

Cognitive Mechanisms Underlying Action Prediction in Children and Adults with Autism Spectrum Condition
Peer reviewed Peer reviewed

Schuwerk, Tobias; Sodian, Beate; Paulus, Markus – Journal of Autism and Developmental Disorders, 2016
Recent research suggests that impaired action prediction is at the core of social interaction deficits in autism spectrum condition (ASC). Here, we targeted two cognitive mechanisms that are thought to underlie the prediction of others' actions: statistical learning and efficiency considerations. We measured proactive eye movements of 10-year-old…

Tillmann, J.; Ashwood, K.; Absoud, M.; Bölte, S.; Bonnet-Brilhault, F.; Buitelaar, J. K.; Calderoni, S.; Calvo, R.; Canal-Bedia, R.; Canitano, R.; De Bildt, A.; Gomot, M.; Hoekstra, P.

C.; Zander, E.; Charman, T. – Journal of Autism and Developmental Disorders, 2018
Research on sex-related differences in Autism Spectrum Disorder (ASD) has been impeded by small samples. We pooled 28 datasets from 18 sites across nine European countries to examine sex differences in the ASD phenotype on the ADI-R (376 females, 1763 males) and ADOS (233 females, 1187 males). On the ADI-R, early childhood restricted and…

Brief Report: Is Cognitive Rehabilitation Needed in Verbal Adults with Autism? Insights from Initial Enrollment in a Trial of Cognitive Enhancement Therapy
Peer reviewed Peer reviewed

Eack, Shaun M.; Bahorik, Amber L.; Hogarty, Susan S.; Greenwald, Deborah P.; Litschge, Maralee Y.; Mazefsky, Carla A.; Minshew, Nancy J. – Journal of Autism and Developmental Disorders, 2013
Cognitive rehabilitation is an emerging set of potentially effective interventions for the treatment of autism spectrum disorder, yet the applicability of these approaches for "high functioning" adults who have normative levels of intelligence remains unexplored. This study examined the initial cognitive performance characteristics of 40…

Theory of Mind in Adults with HFA and Asperger Syndrome
Peer reviewed Peer reviewed
Direct linkDirect link
Spek, Annelies A.; Scholte, Evert M.; Van Berckelaer-Onnes, Ina A. – Journal of Autism and Developmental Disorders, 2010
Theory of mind was assessed in 32 adults with HFA, 29 adults with Asperger syndrome and 32 neurotypical adults. The HFA and Asperger syndrome groups were impaired in performance of the Strange stories test and the Faux-pas test and reported more theory of mind problems than the neurotypical adults. The three groups did not differ in performance of…

The Comparative and Developmental Study of Auditory Information Processing in Autistic Adults.
Peer reviewed Peer reviewed
Nakamura, Kenryu; And Others – Journal of Autism and Developmental Disorders, 1986
The study examined brain functions related to information processing in autistic adults using auditory evoked potentials (AEP) and missing stimulus potentials (MSP). Both nonautistic and autistic adults showed normal mature patterns and lateralities in AEP for music stimuli, but nonautistic children did not. Autistic adults showed matured patterns…

Empirically Derived Subclassification of the Autistic Syndrome.
Peer reviewed Peer reviewed
Siegel, Bryna; And Others – Journal of Autism and Developmental Disorders, 1986
A method for empirical classification of autistic and autisticlike children, based on behavior observations of 35 males and 11 females (ages 4-28 years) was examined. Factor and cluster analysis indicated four subtypes, characterized by perseverative thinking and play, motor disturbances, schizotypal/schizoid features, and anxiety and negativism.…
