Brief Report: Altered Horizontal Binding of Single Dots to Coherent Motion in Autism / Nicole DAVID in Journal of Autism and Developmental Disorders, 40-12 (December 2010)
[article]
Titre : Brief Report: Altered Horizontal Binding of Single Dots to Coherent Motion in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Nicole DAVID, Auteur ; Michael ROSE, Auteur ; Till R. SCHNEIDER, Auteur ; Kai VOGELEY, Auteur ; Andreas K. ENGEL, Auteur Année de publication : 2010 Article en page(s) : p.1549-1551 Langues : Anglais (eng) Mots-clés : Apparent motion Bistable perception Binding Interhemispheric communication High-functioning autism Index. décimale : PER Périodiques Résumé : Individuals with autism often show a fragmented way of perceiving their environment, suggesting a disorder of information integration, possibly due to disrupted communication between brain areas. We investigated thirteen individuals with high-functioning autism (HFA) and thirteen healthy controls using the metastable motion quartet, a stimulus consisting of two dots alternately presented at four locations of a hypothetical square, thereby inducing an apparent motion percept. This percept is vertical or horizontal, the latter requiring binding of motion signals across cerebral hemispheres. Decreasing the horizontal distance between dots could facilitate horizontal percepts. We found evidence for altered horizontal binding in HFA: Individuals with HFA needed stronger facilitation to experience horizontal motion. These data are interpreted in light of reduced cross-hemispheric communication.

[article]
Titre : Dissociation Between Key Processes of Social Cognition in Autism: Impaired Mentalizing But Intact Sense of Agency Type de document : Texte imprimé et/ou numérique Auteurs : Nicole DAVID, Auteur ; Astrid GAWRONSKI, Auteur ; Natacha S. SANTOS, Auteur ; Wolfgang HUFF, Auteur ; Fritz-Georg LEHNHARDT, Auteur ; Albert NEWEN, Auteur ; Kai VOGELEY, Auteur Année de publication : 2008 Article en page(s) : p.593-605 Langues : Anglais (eng) Mots-clés : Mentalizing Sense-of-agency High-functioning-autism Asperger-syndrome Action-monitoring Self-other-distinction Index. décimale : PER Périodiques Résumé : Deficits in social cognition and interaction, such as in mentalizing and imitation behavior, are hallmark features of autism spectrum disorders. Both imitation and mentalizing are at the core of the sense of agency, the awareness that we are the initiators of our own behavior. Little evidence exists regarding the sense of agency in autism. Thus, we compared high-functioning adults with autism to healthy control subjects using an action monitoring and attribution task. Subjects with autism did not show deficits in this task, yet they showed significant mentalizing deficits. Our findings indicate a dissociation between the sense of agency and ascription of mental states in autism. We propose that social-cognitive deficits in autism may arise on a higher level than that of action monitoring and awareness.

Titre : Impairments in multisensory processing are not universal to the autism spectrum: no evidence for crossmodal priming deficits in Asperger syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Nicole DAVID, Auteur ; Till R. SCHNEIDER, Auteur ; Kai VOGELEY, Auteur ; Andreas K. ENGEL, Auteur Année de publication : 2011 Article en page(s) : p.383-388 Langues : Anglais (eng) Mots-clés : Asperger syndrome high-functioning autism multisensory processing crossmodal priming local processing Index. décimale : PER Périodiques Résumé : Individuals suffering from autism spectrum disorders (ASD) often show a tendency for detail- or feature-based perception (also referred to as “local processing bias”) instead of more holistic stimulus processing typical for unaffected people. This local processing bias has been demonstrated for the visual and auditory domains and there is evidence that multisensory processing may also be affected in ASD. Most multisensory processing paradigms used social-communicative stimuli, such as human speech or faces, probing the processing of simultaneously occuring sensory signals. Multisensory processing, however, is not limited to simultaneous stimulation. In this study, we investigated whether multisensory processing deficits in ASD persist when semantically complex but nonsocial stimuli are presented in succession. Fifteen adult individuals with Asperger syndrome and 15 control persons participated in a visual-audio priming task, which required the classification of sounds that were either primed by semantically congruent or incongruent preceding pictures of objects. As expected, performance on congruent trials was faster and more accurate compared with incongruent trials (crossmodal priming effect). The Asperger group, however, did not differ significantly from the control group. Our results do not support a general multisensory processing deficit, which is universal to the entire autism spectrum.

BEWERNICK, Auteur Année de publication : 2010 Article en page(s) : p.290-299 Langues : Anglais (eng) Mots-clés : Social-cognition Mentalizing Visuospatial-perspective-taking- Asperger-Syndrome Autism Index. décimale : PER Périodiques Résumé : Mentalizing refers to making inferences about other people’s mental states, whereas visuospatial perspective taking refers to inferring other people’s viewpoints. Both abilities seem vital for social functioning; yet, their exact relationship is unclear. We directly compared mentalizing and visuospatial perspective taking in nineteen adults with Asperger syndrome (AS) and fifteen control participants with the same stimulus material. Stimuli depicted virtual characters surrounded by two different objects. Virtual characters expressed a preference for one of the objects indicated by facial expression, gestures or head/body orientation. Compared to controls, participants with AS showed significantly increased reaction times and decreased accuracy for mentalizing (i.e., when inferring the virtual character’s preference from the character’s nonverbal bodily cues). By contrast, there were no significant group differences in perspective taking (i.e., by mental own-body transformations). These findings demonstrate, first, specific deficits in AS when mental states have to be inferred from nonverbal social cues. Second, visuospatial perspective taking may not necessarily be related to social impairments occurring in autism spectrum disorders.

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.
