Reading performance is similar for the two groups in both languages. While reading Mandarin Chinese, the control group showed a left-hemispheric specialization within the 400–600 ms interval in delta synchronization. However, delta synchronizations were widely distributed in all scalp regions and lasted longer than 600 ms in the AS group. One possible interpretation of our data is the hypothesis that the AS group has more difficulty in brain organization of semantic and syntactic processes than the control group when reading their native language, because Chinese syntactic structure requires more work to be done by the perceiver. Nevertheless, other brain mechanisms (e.g., top-down regulation), can partially compensate for this difficulty, allowing AS subjects to attain the same level of response activity as the controls.

Voluntary attention in Asperger's syndrome: Brain electrical oscillation and phase-synchronization during facial emotion recognition / Yi-Li TSENG in Research in Autism Spectrum Disorders, 13-14 (May 2015)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 13-14 (May 2015) . - p.32-51 Titre : Voluntary attention in Asperger's syndrome: Brain electrical oscillation and phase-synchronization during facial emotion recognition Type de document : Texte imprimé et/ou numérique Auteurs : Yi-Li TSENG, Auteur ; Han Hsuan YANG, Auteur ; Alexander N. SAVOSTYANOV, Auteur ; Vincent S. C. CHIEN, Auteur ; Michelle LIOU, Auteur Article en page(s) : p.32-51 Langues : Anglais (eng) Mots-clés : Asperger syndrome  EEG  Facial emotion recognition  Spatial frequency  Event-related spectral perturbations (ERSP)  Phase synchronization Index. décimale : PER Périodiques Résumé : Abstract This study investigated electroencephalography (EEG) oscillatory activity and phase-synchronization in patients with Asperger's syndrome (AS) during visual recognition of emotional faces. In the experiment, 10 AS adults (2 females, age 19.6 ± 1.96) and 10 IQ-matched controls (3 females, age 24.4 ± 3.24) participated in tasks involving emotionality evaluation of either photograph or line-drawing faces. Emotional faces elicited comparable reaction times and evaluation scores between the two groups. In the photograph task, the AS group had no visible N400 component and lower delta/theta synchronization (350–450 ms post-stimulus onset) in the temporal and occipital–parietal regions, and much weaker phase synchronization between distant scalp regions (200–500 ms post-stimulus onset) compared with the control group. In the line-drawing task, the two groups had the same degree of delta/theta synchronization in the central and occipital–parietal regions and comparable phase synchronization between scalp regions. We conclude by hypothesizing that AS patients might have structural deficits in the amygdala and its related limbic structures, a site critical for recognition of emotional faces beyond conscious awareness, but that they preserve the intact function in the cognitive pathway to keep up comparable behavioral performances with the healthy controls through voluntary control of attention.
