Tse, Venus W. S.; Crabtree, Jason; Islam, Shamsun; Stott, Joshua – Journal of Autism and Developmental Disorders, 2019
This study aimed to compare cognitive and memory abilities between older adults with and without autism over the age of 50. Twenty-eight individuals with autism and 29 typically developing (TD) older adults took part in the current study. Participants' cognitive and memory abilities were assessed by WAIS-IV and WMS-IV. Older autistic adults were…

Margoni, Francesco; Guglielmetti, Giulia; Surian, Luca – Journal of Autism and Developmental Disorders, 2019
Past research suggested that, due to difficulties in mentalistic reasoning, individuals with autism tend to base their moral judgments on the outcome of agents' actions rather than on agents' intentions. In a novel task, aimed at reducing the processing demands required to represent intentions and generate a judgment, autistic children were…

Rosa, Mireia; Puig, Olga; Lázaro, Luisa; Vallés, Virginia; Lera, Sara; Sánchez-Gistau, Vanesa; Calvo, Rosa – Journal of Autism and Developmental Disorders, 2017
Despite evidence supporting the presence of cognitive deficits in children and adolescents with high-functioning autism spectrum disorder (HF-ASD), the nature of these deficits and their clinical and adaptive correlates remain unclear. Moreover, there are few cognitive studies of ASD siblings as a high risk population. We compared 50 children and…

Vanmarcke, Steven; Mullin, Caitlin; Van der Hallen, Ruth; Evers, Kris; Noens, Ilse; Steyaert, Jean; Wagemans, Johan – Journal of Autism and Developmental Disorders, 2016
Typically developing (TD) adults are able to extract global information from natural images and to categorize them within a single glance. This study aimed at extending these findings to individuals with autism spectrum disorder (ASD) using a free description open-encoding paradigm. Participants were asked to freely describe what they saw when…

Gökçen, Elif; Frederickson, Norah; Petrides, K. V. – Journal of Autism and Developmental Disorders, 2016
Autism spectrum disorder (ASD) is characterised by profound difficulties in empathic processing and executive control. Whilst the links between these processes have been frequently investigated in populations with autism, few studies have examined them at the subclinical level. In addition, the contribution of alexithymia, a trait characterised by…

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…

Costescu, Cristina A.; Vanderborght, Bram; David, Daniel O. – Journal of Autism and Developmental Disorders, 2015
Children with autism spectrum disorder (ASD) engage in highly perseverative and inflexible behaviours. Technological tools, such as robots, received increased attention as social reinforces and/or assisting tools for improving the performance of children with ASD. The aim of our study is to investigate the role of the robotic toy Keepon in a…

Falck-Ytter, Terje; Thorup, Emilia; Bölte, Sven – Journal of Autism and Developmental Disorders, 2015
Whether gaze following--a key component of joint attention--is impaired in children with autism spectrum disorder (ASD) is currently debated. Functional gaze following involves saccading towards the attended rather than unattended targets (accuracy) as well as a subsequent processing bias for attended objects. Using non-invasive eye tracking…

Miller, Haylie L.; Ragozzino, Michael E.; Cook, Edwin H.; Sweeney, John A.; Mosconi, Matthew W. – Journal of Autism and Developmental Disorders, 2015
The neurocognitive impairments associated with restricted and repetitive behaviors (RRBs) in autism spectrum disorder (ASD) are not yet clear. Prior studies indicate that individuals with ASD show reduced cognitive flexibility, which could reflect difficulty shifting from a previously learned response pattern or a failure to maintain a new…

Doobay, Alissa F.; Foley-Nicpon, Megan; Ali, Saba R.; Assouline, Susan G. – Journal of Autism and Developmental Disorders, 2014
Research on Autism Spectrum Disorder (ASD) is thriving; however, scant empirical research has investigated how ASD manifests in high ability youth. Further research is necessary to accurately differentiate high ability students with ASD from those without the disorder, and thus decrease the risk of misdiagnosis. The purpose of the present study is…

Eack, Shaun M.; Greenwald, Deborah P.; Hogarty, Susan S.; Bahorik, Amber L.; Litschge, Maralee Y.; Mazefsky, Carla A.; Minshew, Nancy J. – Journal of Autism and Developmental Disorders, 2013
Adults with autism experience significant impairments in social and non-social information processing for which few treatments have been developed. This study conducted an 18-month uncontrolled trial of Cognitive Enhancement Therapy (CET), a comprehensive cognitive rehabilitation intervention, in 14 verbal adults with autism spectrum disorder to…

Sachse, Michael; Schlitt, Sabine; Hainz, Daniela; Ciaramidaro, Angela; Schirman, Shella; Walter, Henrik; Poustka, Fritz; Bolte, Sven; Freitag, Christine M. – Journal of Autism and Developmental Disorders, 2013
This study broadly examines executive (EF) and visuo-motor function in 30 adolescent and adult individuals with high-functioning autism spectrum disorder (ASD) in comparison to 28 controls matched for age, gender, and IQ. ASD individuals showed impaired spatial working memory, whereas planning, cognitive flexibility, and inhibition were spared.…

FMRI was performed with the dynamic facial expressions fear and happiness. This was done to detect differences in valence processing between 25 subjects with autism spectrum disorders (ASDs) and 27 typically developing controls. Valence scaling was abnormal in ASDs. Positive valence induces lower deactivation and abnormally strong activity in ASD…

Poljac, Edita; Poljac, Ervin; Yeung, Nick – Journal of Autism and Developmental Disorders, 2012
Impairments in cognitive control generating deviant adaptive cognition have been proposed to account for the strong preference for repetitive behavior in autism. We examined if this preference reflects intentional deficits rather than problems in task execution in the broader autism phenotype using the Autism-Spectrum Quotient (AQ). Participants…

de Vries, Marieke; Geurts, Hilde M. – Journal of Autism and Developmental Disorders, 2012
Children with autism spectrum disorders (ASDs) show daily cognitive flexibility deficits, but laboratory data are unconvincing. The current study aimed to bridge this gap. Thirty-one children with ASD (8-12 years) and 31 age- and IQ-matched typically developing children performed a gender emotion switch task. Unannounced switches and complex…
