Anticipation of Action Intentions in Autism Spectrum Disorder / Matthew HUDSON in Journal of Autism and Developmental Disorders, 42-8 (August 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-8 (August 2012) . - p.1684-1693 Titre : Anticipation of Action Intentions in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Matthew HUDSON, Auteur ; Hollie G. BURNETT, Auteur ; Tjeerd JELLEMA, Auteur Année de publication : 2012 Article en page(s) : p.1684-1693 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Gaze direction  Action anticipation  Representational momentum  Motor intention  Goal directed action Index. décimale : PER Périodiques Résumé : We investigated whether individuals with a mild form of autism spectrum disorder (ASD) are influenced by an actor’s gaze direction when anticipating how an observed action will continue in the immediate future. Participants observed a head rotate towards them, while the gaze direction was either leading, or lagging behind, rotation. They also observed identical rotations of a cylinder containing the geometrical equivalent of the gaze manipulation. The control group was influenced by the gaze manipulations for the animate but not the inanimate stimulus. The ASD group did not discriminate between the stimuli, showing a similar influence for both. This suggests that the ASD responses in the animate condition were biased by the low-level directional features of the eyes rather than by the conveyed intentions.

Atypical emotional anticipation in high-functioning autism / Letizia PALUMBO in Molecular Autism, (August 2015)  

Public ISBD [article]  inMolecular Autism > (August 2015) . - p.1-17 Titre : Atypical emotional anticipation in high-functioning autism Type de document : Texte imprimé et/ou numérique Auteurs : Letizia PALUMBO, Auteur ; Hollie G. BURNETT, Auteur ; Tjeerd JELLEMA, Auteur Article en page(s) : p.1-17 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Understanding and anticipating others’ mental or emotional states relies on the processing of social cues, such as dynamic facial expressions. Individuals with high-functioning autism (HFA) may process these cues differently from individuals with typical development (TD) and purportedly use a ‘mechanistic’ rather than a ‘mentalistic’ approach, involving rule- and contingency-based interpretations of the stimuli. The study primarily aimed at examining whether the judgments of facial expressions made by individuals with TD and HFA would be similarly affected by the immediately preceding dynamic perceptual history of that face. A second aim was to explore possible differences in the mechanisms underpinning the perceptual judgments in the two groups.

Brief Report: An Evaluation of the AQ-10 as a Brief Screening Instrument for ASD in Adults / Tom BOOTH in Journal of Autism and Developmental Disorders, 43-12 (December 2013)

BURNETT, Auteur Article en page(s) : p.2997-3000 Langues : Anglais (eng) Mots-clés : Autism  AQ  ASD  Screening  ROC analysis Index. décimale : PER Périodiques Résumé : There is a need for brief screening instruments for autistic spectrum disorders (ASD) that can be used by frontline healthcare professionals to aid in the decision as to whether an individual should be referred for a full diagnostic assessment. In this study we evaluated the ability of a short form of the autism spectrum quotient (AQ) questionnaire, the 10 item AQ-10, to correctly classify individuals as having or not having ASD. In a sample of 149 individuals with ASD and 134 controls without an ASD diagnosis, we found that the full AQ (AQ-50) abridged AQ (AQ-S) and AQ-10 all performed well as a screen for ASD. ROC analysis indicated that sensitivity, specificity and area under the curve were very similar at suggested cut-off’s for ASD across measures, with little difference in performance between the AQ-10 and full AQ-50. Results indicate the potential usefulness of the AQ-10 as a brief screen for ASD.

Impaired Identification of Impoverished Animate but not Inanimate Objects in Adults With High-Functioning Autism Spectrum Disorder / Hollie G. BURNETT in Autism Research, 8-1 (February 2015)  

Public ISBD [article]  inAutism Research > 8-1 (February 2015) . - p.52-60 Titre : Impaired Identification of Impoverished Animate but not Inanimate Objects in Adults With High-Functioning Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Hollie G. BURNETT, Auteur ; Sven PANIS, Auteur ; Johan WAGEMANS, Auteur ; Tjeerd JELLEMA, Auteur Article en page(s) : p.52-60 Langues : Anglais (eng) Mots-clés : autism spectrum disorder (ASD)  concept forming  Gabor  impoverished objects  animate  inanimate Index. décimale : PER Périodiques Résumé : The ability to identify animate and inanimate objects from impoverished images was investigated in adults with high-functioning autism spectrum disorder (HFA) and in matched typically developed (TD) adults, using a newly developed task. Consecutive frames were presented containing Gabor elements that slightly changed orientation from one frame to the next. For a subset of elements, the changes were such that these elements gradually formed the outline of an object. Elements enclosed within the object's outline gradually adopted one and the same orientation, outside elements adopted random orientations. The subjective experience was that of an object appearing out of a fog. The HFA group required significantly more frames to identify the impoverished objects than the TD group. Crucially, this difference depended on the nature of the objects: the HFA group required significantly more frames to identify animate objects, but with respect to the identification of inanimate objects the groups did not differ. The groups also did not differ with respect to the number and type of incorrect guesses they made. The results suggest a specific impairment in individuals with HFA in identifying animate objects. A number of possible explanations are discussed. Autism Res 2015, 8: 52–60.

Linguistic Alignment in Adults with and Without Asperger’s Syndrome / Katie E. SLOCOMBE in Journal of Autism and Developmental Disorders, 43-6 (June 2013)

We investigated if these difficulties could be attributable to a deficit in the ability to linguistically converge with an interlocutor, which is posited to be important for successful communication. To that end, participants completed two cooperative tasks with a confederate, which allowed us to measure linguistic alignment with the confederate in terms of lexical choice, syntactic structure and spatial frame of reference. There was no difference in the performance of individuals with AS and matched controls and both groups showed significant alignment with the confederate at all three levels. We conclude that linguistic alignment is intact in adults with AS engaged in structured, goal-directed social interactions.
