Mirror me: Imitative responses in adults with autism / Odette SCHUNKE in Autism, 20-2 (February 2016)

Titre : Mirror me: Imitative responses in adults with autism Type de document : Texte imprimé et/ou numérique Auteurs : Odette SCHUNKE, Auteur ; Daniel SCHOTTLE, Auteur ; Eik VETTORAZZI, Auteur ; Valerie BRANDT, Auteur ; Ursula KAHL, Auteur ; Tobias BÄUMER, Auteur ; Christos GANOS, Auteur ; Nicole DAVID, Auteur ; Ina PEIKER, Auteur ; Andreas K ENGEL, Auteur ; Marcel BRASS, Auteur ; Alexander MUNCHAU, Auteur Article en page(s) : p.134-144 Langues : Anglais (eng) Mots-clés : autism imitation interference mirror neurons reaction times Index. décimale : PER Périodiques Résumé : Dysfunctions of the human mirror neuron system have been postulated to underlie some deficits in autism spectrum disorders including poor imitative performance and impaired social skills. Using three reaction time experiments addressing mirror neuron system functions under simple and complex conditions, we examined 20 adult autism spectrum disorder participants and 20 healthy controls matched for age, gender and education. Participants performed simple finger-lifting movements in response to (1) biological finger and non-biological dot movement stimuli, (2) acoustic stimuli and (3) combined visual-acoustic stimuli with different contextual (compatible/incompatible) and temporal (simultaneous/asynchronous) relation. Mixed model analyses revealed slower reaction times in autism spectrum disorder. Both groups responded faster to biological compared to non-biological stimuli (Experiment 1) implying intact processing advantage for biological stimuli in autism spectrum disorder. In Experiment 3, both groups had similar ‘interference effects’ when stimuli were presented simultaneously. However, autism spectrum disorder participants had abnormally slow responses particularly when incompatible stimuli were presented consecutively. Our results suggest imitative control deficits rather than global imitative system impairments.

Titre : Visual Search Performance Does Not Relate to Autistic Traits in the General Population Type de document : Texte imprimé et/ou numérique Auteurs : D. LOPEZ PEREZ, Auteur ; D. P. KENNEDY, Auteur ; P. TOMALSKI, Auteur ; Sven BÖLTE, Auteur ; B. D'ONOFRIO, Auteur ; T. FALCK-YTTER, Auteur Article en page(s) : p.2624-2631 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Eye movements Eye tracking Reaction times Visual search task Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is commonly conceived as the extreme end of a continuum. Research suggests that autistic individuals outperform typically developing controls in visual search. Thus, enhanced visual search may represent an adaptive trait associated with ASD. Here, using a large general population sample (N = 608, aged 9-14 years), we tested if higher levels of autistic traits are associated with enhanced visual search. Visual search was evaluated using both manual responses and eye movements, and autistic traits were measured using the Social Responsiveness Scale. Contrary to our hypothesis, no significant relation between autistic traits and visual search were observed. The theoretical implications of these results are discussed.
