Goldman, Sylvie; O'Brien, Liam M.; Filipek, Pauline A.; Rapin, Isabelle; Herbert, Martha R. – Research in Autism Spectrum Disorders, 2013
Motor stereotypies are defined as patterned, repetitive, purposeless movements. These stigmatizing motor behaviors represent one manifestation of the third core criterion for an Autistic Disorder (AD) diagnosis, and are becoming viewed as potential early markers of autism. Moreover, motor stereotypies might be a tangible expression of the…

Han, Yvonne M. Y.; Chan, Agnes S.; Sze, Sophia L.; Cheung, Mei-Chun; Wong, Chun-kwok; Lam, Joseph M. K.; Poon, Priscilla M. K. – Research in Autism Spectrum Disorders, 2013
Previous studies have shown that children with autism spectrum disorders (ASDs) have impaired executive function, disordered neural connectivity, and abnormal immunologic function. The present study examined whether these abnormalities were associated. Seventeen high-functioning (HFA) and 17 low-functioning (LFA) children with ASD, aged 8-17…

Doyle-Thomas, Krissy A. R.; Duerden, Emma G.; Taylor, Margot J.; Lerch, Jason P.; Soorya, Latha V.; Wang, A. Ting; Fan, Jin; Hollander, Eric; Anagnostou, Evdokia – Research in Autism Spectrum Disorders, 2013
Several brain regions show structural and functional abnormalities in individuals with autism spectrum disorders (ASD), but the developmental trajectory of abnormalities in these structures and how they may relate to social and communicative impairments are still unclear. We assessed the effects of age on cortical thickness in individuals with…

Chan, Agnes S.; Han, Yvonne M. Y.; Sze, Sophia L.; Cheung, Mei-chun; Leung, Winnie Wing-man; Chan, Raymond C. K.; To, Cho Yee – Research in Autism Spectrum Disorders, 2011
The present study examined the memory performance and cortical connectivity of children with ASD, and investigated whether the memory deficits exhibited by these children were associated with the cortical connectivity. Twenty-one children with ASD and 21 children with normal development (NC), aged 5-14 years, participated in the study. Each child…

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…

Cheung, Mei-chun; Chan, Agnes S.; Sze, Sophia L.; Leung, Winnie W.; To, Cho Yee – Research in Autism Spectrum Disorders, 2010
The present study examined the verbal memory profile and its relation to organizational strategies in high-functioning (Hi-AUT) and low-functioning (Lo-AUT) children with autism. Twenty-two Hi-AUT and 16 Lo-AUT, and 22 age-, gender- and handedness-matched normal children (NC) were required to remember a list of semantically related words for…
