Emotional prosodic change detection in autism Spectrum disorder: an electrophysiological investigation in children and adults / J. CHARPENTIER in Journal of Neurodevelopmental Disorders, 10-1 (December 2018)

Titre : Emotional prosodic change detection in autism Spectrum disorder: an electrophysiological investigation in children and adults Type de document : Texte imprimé et/ou numérique Auteurs : J. CHARPENTIER, Auteur ; K. KOVARSKI, Auteur ; Emmanuelle HOUY-DURAND, Auteur ; J. MALVY, Auteur ; A. SABY, Auteur ; Frédérique BONNET-BRILHAULT, Auteur ; Marianne LATINUS, Auteur ; Marie GOMOT, Auteur Année de publication : 2018 Article en page(s) : 28 p. Langues : Anglais (eng) Mots-clés : Adults Autism spectrum disorder Change detection Children Eeg Emotion Mismatch negativity (MMN) Prosody Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism spectrum disorder (ASD) is characterized by atypical behaviors in social environments and in reaction to changing events. While this dyad of symptoms is at the core of the pathology along with atypical sensory behaviors, most studies have investigated only one dimension. A focus on the sameness dimension has shown that intolerance to change is related to an atypical pre-attentional detection of irregularity. In the present study, we addressed the same process in response to emotional change in order to evaluate the interplay between alterations of change detection and socio-emotional processing in children and adults with autism. METHODS: Brain responses to neutral and emotional prosodic deviancies (mismatch negativity (MMN) and P3a, reflecting change detection and orientation of attention toward change, respectively) were recorded in children and adults with autism and in controls. Comparison of neutral and emotional conditions allowed distinguishing between general deviancy and emotional deviancy effects. Moreover, brain responses to the same neutral and emotional stimuli were recorded when they were not deviants to evaluate the sensory processing of these vocal stimuli. RESULTS: In controls, change detection was modulated by prosody: in children, this was characterized by a lateralization of emotional MMN to the right hemisphere, and in adults, by an earlier MMN for emotional deviancy than for neutral deviancy. In ASD, an overall atypical change detection was observed with an earlier MMN and a larger P3a compared to controls suggesting an unusual pre-attentional orientation toward any changes in the auditory environment. Moreover, in children with autism, deviancy detection depicted reduced MMN amplitude. In addition in children with autism, contrary to adults with autism, no modulation of the MMN by prosody was present and sensory processing of both neutral and emotional vocal stimuli appeared atypical. CONCLUSIONS: Overall, change detection remains altered in people with autism. However, differences between children and adults with ASD evidence a trend toward normalization of vocal processing and of the automatic detection of emotion deviancy with age.

MINSHEW, Auteur ; Beatriz LUNA, Auteur Année de publication : 2011 Article en page(s) : p.132-142 Langues : Anglais (eng) Mots-clés : ASD change detection development developmental disorder people perception social cognition Index. décimale : PER Périodiques Résumé : People with autism spectrum disorders (ASD) process visual information in a manner that is distinct from typically developing individuals. They may be less sensitive to people's goals and, more generally, focus on visual details instead of the entire scene. To examine these differences, people with and without ASD were asked to detect changes in dynamic scenes with multiple elements. Participants viewed a brief video of a person or an inanimate object (the “figure”) moving from one object to another; after a delay, they reported whether a second video was the same or different. Possible changes included the figure, the object the figure was moving from, or the object the figure was moving toward (the “goal”). We hypothesized that individuals with ASD would be less sensitive to changes in scenes with people, particularly elements that might be the person's goal. Alternately, people with ASD might attend to fewer elements regardless of whether the scene included a person. Our results indicate that, like controls, people with ASD noticed a change in the “goal” object at the end of a person's movement more often than the object at the start. However, the group with ASD did not undergo the developmental improvement that was evident typically when detecting changes in both the start and end objects. This atypical development led to deficits in adults with ASD that were not specific to scenes with people or to “goals.” Improvements in visual processing that underlie mature representation of scenes may not occur in ASD, suggesting that late developing brain processes are affected.

Children and adolescents relied more on social referencing cues in the scene as compared to adults, and in the presence of such cues, were less able to use other kinds of cues. Typically developing children and adolescents were no better than those with ASD at detecting changes within the various social contexts. Results suggest children and adolescents with ASD use relevant social cues while searching a scene just as typical children do.

Twenty-two children diagnosed with ASD and 22 matched typically developing (TD) children were told to detect changes in objects of central interest or objects of marginal interest (MI) embedded in either emotion-laden (positive or negative) or neutral real-world pictures. The results showed that emotion-laden pictures equally interfered with performance of both ASD and TD children, slowing down reaction times compared with neutral pictures. Children with ASD were faster than TD children, particularly in detecting changes in MI objects, the most difficult condition. However, their performance was less accurate than performance of TD children just when the pictures were negative. These findings suggest that children with ASD have better visual search abilities than TD children only when the search is particularly difficult and requires strong serial search strategies. The emotional–social impairment that is usually considered as a typical feature of ASD seems to be limited to processing of negative emotional information.
