MAGNEE, Auteur ; Herman VAN ENGELAND, Auteur ; Béatrice DE GELDER, Auteur ; Chantal KEMNER, Auteur Année de publication : 2008 Article en page(s) : p.995-1000 Langues : Anglais (eng) Mots-clés : Multisensory-integration language-and-communication autism EEG visual auditory Index. décimale : PER Périodiques Résumé : Background: Integration of information from multiple sensory sources is an important prerequisite for successful social behavior, especially during face-to-face conversation. It has been suggested that communicative impairments among individuals with pervasive developmental disorders (PDD) might be caused by an inability to integrate synchronously presented visual and auditory cues. Method: We investigated audiovisual integration of speech stimuli among a group of high-functioning adult PDD individuals and age- and IQ-matched controls using electroencephalography, measuring both early pre-phonological, as well as late phonologically driven integration. Results: Pre-phonological AV interactions are intact, while AV interactions corresponding to more complex phonological processes are impaired in individuals with PDD. Conclusions: The present findings argue for a pattern of impairments on tasks related to complex audiovisual integration combined with relative sparing of low-level integrational abilities. This combination may very well contribute to the communicative disabilities which are typical for the disorder.

Facial electromyographic responses to emotional information from faces and voices in individuals with pervasive developmental disorder / Maurice J.C.M. MAGNEE in Journal of Child Psychology and Psychiatry, 48-11 (November 2007)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 48-11 (November 2007) . - p.1122–1130 Titre : Facial electromyographic responses to emotional information from faces and voices in individuals with pervasive developmental disorder Type de document : Texte imprimé et/ou numérique Auteurs : Maurice J.C.M. MAGNEE, Auteur ; Herman VAN ENGELAND, Auteur ; Béatrice DE GELDER, Auteur ; Chantal KEMNER, Auteur Année de publication : 2007 Article en page(s) : p.1122–1130 Langues : Anglais (eng) Mots-clés : Autism emotional-processing facial-expressions voice-prosody electromyography-(EMG) multisensory-perception Index. décimale : PER Périodiques Résumé : Despite extensive research, it is still debated whether impairments in social skills of individuals with pervasive developmental disorder (PDD) are related to specific deficits in the early processing of emotional information. We aimed to test both automatic processing of facial affect as well as the integration of auditory and visual emotion cues in individuals with PDD. Methods: In a group of high-functioning adult individuals with PDD and an age- and IQ-matched control group, we measured facial electromyography (EMG) following presentation of visual emotion stimuli (facial expressions) as well as the presentation of audiovisual emotion pairs (faces plus voices). This emotionally driven EMG activity is considered to be a direct correlate of automatic affect processing that is not under intentional control. Results: Our data clearly indicate that among individuals with PDD facial EMG activity is heightened in response to happy and fearful faces, and intact in response to audiovisual affective information. Conclusions: This study provides evidence for enhanced sensitivity to facial cues at the level of reflex-like emotional responses in individuals with PDD. Furthermore, the findings argue against impairments in crossmodal affect processing at this level of perception. However, given how little comparative work has been done in the area of multisensory perception, there is certainly need for further exploration.
