Cole, Eleanor J.; Slocombe, Katie E.; Barraclough, Nick E. – Journal of Autism and Developmental Disorders, 2018
Previous research suggests that Autism Spectrum Disorder (ASD) might be associated with impairments on implicit but not explicit mentalizing tasks. However, such comparisons are made difficult by the heterogeneity of stimuli and the techniques used to measure mentalizing capabilities. We tested the abilities of 34 individuals (17 with ASD) to…

Cole, Eleanor J.; Barraclough, Nick E.; Enticott, Peter G. – Journal of Autism and Developmental Disorders, 2018
ASD is associated with mentalizing deficits that may correspond with atypical mirror system (MS) activation. We investigated MS activity in adults with and without ASD when inferring others' intentions using TMS-induced motor evoked potentials (MEPs) and mu suppression measured by EEG. Autistic traits were measured for all participants. Our EEG…

Ziermans, Tim; Swaab, Hanna; Stockmann, Alexander; de Bruin, Esther; van Rijn, Sophie – Journal of Autism and Developmental Disorders, 2017
Formal thought disorder (FTD) is a disruption in the flow of thought and a common feature in psychotic disorders and autism spectrum disorder (ASD). Executive dysfunction has often been associated with FTD, yet for ASD convincing evidence is lacking. This study investigated FTD and three core executive functions in 50 young children and…

Cage, Eilidh; Bird, Geoffrey; Pellicano, Elizabeth – Journal of Autism and Developmental Disorders, 2016
Being able to manage reputation is an important social skill, but it is unclear whether autistic children can manage reputation. This study investigated whether 33 autistic children matched to 33 typical children could implicitly or explicitly manage reputation. Further, we examined whether cognitive processes--theory of mind, social motivation,…

Brosnan, Mark; Lewton, Marcus; Ashwin, Chris – Journal of Autism and Developmental Disorders, 2016
Dual process theory proposes two distinct reasoning processes in humans, an intuitive style that is rapid and automatic and a deliberative style that is more effortful. However, no study to date has specifically examined these reasoning styles in relation to the autism spectrum. The present studies investigated deliberative and intuitive reasoning…

Waite, Jane; Beck, Sarah R.; Heald, Mary; Powis, Laurie; Oliver, Chris – Journal of Autism and Developmental Disorders, 2016
Working memory (WM) impairments might amplify behavioural difference in genetic syndromes. Murine models of Rubinstein-Taybi syndrome (RTS) evidence memory impairments but there is limited research on memory in RTS. Individuals with RTS and typically developing children completed WM tasks, with participants with RTS completing an IQ assessment and…

Bowler, Dermot M.; Gaigg, Sebastian B.; Gardiner, John M. – Journal of Autism and Developmental Disorders, 2015
Adults with autism spectrum disorder (ASD) show intact recognition (supported procedure) but impaired recall (unsupported procedure) of incidentally-encoded context. Because this has not been demonstrated for temporal source, we compared the temporal and spatial source memory of adults with ASD and verbally matched typical adults. Because of…

Solomon, Marjorie; Buaminger, Nirit; Rogers, Sally J. – Journal of Autism and Developmental Disorders, 2011
To investigate the relationship between cognitive and social functioning, 20 Israeli individuals with HFASD aged 8-12 and 22 age, maternal education, and receptive vocabulary-matched preadolescents with typical development (TYP) came to the lab with a close friend. Measures of abstract reasoning, friendship quality, and dyadic interaction during a…

Koyama, Tomonori; Kamio, Yoko; Inada, Naoko; Kurita, Hiroshi – Journal of Autism and Developmental Disorders, 2009
Using the Japanese version of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III), 26 girls with high-functioning (IQ greater than or equal to 70) pervasive developmental disorders (HFPDD) (mean age, 8.2 years) were compared with 116 boys with HFPDD (mean age, 9.0 years). Compared with the boys, the girls scored significantly…

Age- and IQ-balanced 27 children with high-functioning (IQ greater than or equal to 70) pervasive developmental disorder not otherwise specified (HPDDNOS) and 27 children with attention-deficit/hyperactivity disorder (ADHD) were compared on the Japanese version of Wechsler Intelligence Scale for Children Third Edition (WISC-III) and the Childhood…

Mottron, Laurent; Dawson, Michelle; Soulieres, Isabelle; Hubert, Benedicte; Burack, Jake – Journal of Autism and Developmental Disorders, 2006
We propose an "Enhanced Perceptual Functioning" model encompassing the main differences between autistic and non-autistic social and non-social perceptual processing: locally oriented visual and auditory perception, enhanced low-level discrimination, use of a more posterior network in "complex" visual tasks, enhanced perception…

Zwaigenbaum, L; Sonnenberg, L. K.; Heshka, T.; Eastwood, S.; Xu, J. – Journal of Autism and Developmental Disorders, 2005
We report a 4-year-old girl with a "de novo", apparently balanced complex chromosome rearrangement. She initially presented for assessment of velopharyngeal insufficiency due to hypernasal speech. She has distinctive facial features (long face, broad nasal bridge, and protuberant ears with simplified helices), bifid uvula, strabismus,…

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),…

Hill, Elisabeth; Berthoz, Sylvie; Frith, Uta – Journal of Autism and Developmental Disorders, 2004
Difficulties in the cognitive processing of emotions--including difficulties identifying and describing feelings--are assumed to be an integral part of autism. We studied such difficulties via self-report in 27 high-functioning adults with autistic spectrum disorders, their biological relatives (n = 49), and normal adult controls (n = 35), using…

Gagnon, Louise; Mottron, Laurent; Bherer, Louis; Joanette, Yves – Journal of Autism and Developmental Disorders, 2004
This study examined the hypothesis of superior quantification abilities of persons with high functioning autism (HFA). Fourteen HFA individuals (mean age: 15 years) individually matched with 14 typically developing (TD) participants (gender, chronological age, full-scale IQ) were asked to quantify as accurately and quickly as possible…
