Maekawa, Toshihiko; Tobimatsu, Shozo; Inada, Naoko; Oribe, Naoya; Onitsuka, Toshiaki; Kanba, Shigenobu; Kamio, Yoko – Research in Autism Spectrum Disorders, 2011
Individuals with high-functioning autism spectrum disorder (HF-ASD) often show superior performance in simple visual tasks, despite difficulties in the perception of socially important information such as facial expression. The neural basis of visual perception abnormalities associated with HF-ASD is currently unclear. We sought to elucidate the…

Keane, Brian P.; Rosenthal, Orna; Chun, Nicole H.; Shams, Ladan – Research in Autism Spectrum Disorders, 2010
Autism involves various perceptual benefits and deficits, but it is unclear if the disorder also involves anomalous audiovisual integration. To address this issue, we compared the performance of high-functioning adults with autism and matched controls on experiments investigating the audiovisual integration of speech, spatiotemporal relations, and…

Falkmer, Marita; Bjallmark, Anna; Larsson, Matilda; Falkmer, Torbjorn – Research in Autism Spectrum Disorders, 2011
Can the disadvantages persons with Asperger syndrome frequently experience with reading facially expressed emotions be attributed to a different visual perception, affecting their scanning patterns? Visual search strategies, particularly regarding the importance of information from the eye area, and the ability to recognise facially expressed…

Yamasaki, Takao; Fujita, Takako; Ogata, Katsuya; Goto, Yoshinobu; Munetsuna, Shinji; Kamio, Yoko; Tobimatsu, Shozo – Research in Autism Spectrum Disorders, 2011
People with autism spectrum disorder (ASD) often show inferior global motion performance with superior performance in detail form perception, suggesting dysfunction of the dorsal visual stream. To elucidate the neural basis of impaired global motion perception in ASD, we measured psychophysical threshold and visual event-related potentials (ERPs)…

Haesen, Birgitt; Boets, Bart; Wagemans, Johan – Research in Autism Spectrum Disorders, 2011
This literature review aims to interpret behavioural and electrophysiological studies addressing auditory processing in children and adults with autism spectrum disorder (ASD). Data have been organised according to the applied methodology (behavioural versus electrophysiological studies) and according to stimulus complexity (pure versus complex…

Kern, Janet K.; Garver, Carolyn R.; Carmody, Thomas; Andrews, Alonzo A.; Trivedi, Madhukar H.; Mehta, Jyutika A. – Research in Autism Spectrum Disorders, 2007
The purpose of this study was to examine sensory quadrants in autism based on Dunn's Theory of Sensory Processing. The data for this study was collected as part of a cross-sectional study that examined sensory processing (using the Sensory Profile) in 103 persons with autism, 3-43 years of age, compared to 103 age- and gender-matched community…
