Pupillary response during social emotion tasks in autism spectrum disorder / Juei-Po LEE in Autism Research, 17-10 (October 2024)

Pupillary response has been proposed as an indicator of arousal dysregulation or cognitive load. The pupillary response of autistic individuals during socio-affective tasks remains unclear. This study investigated pupillary response in autistic adults when viewing emotional faces/eyes and recognizing emotions during the Reading the Mind in the Eyes Test (RMET) and watching interpersonal touch scenes in the social touch task. The study included 98 participants diagnosed with autism spectrum disorder and 37 typically developing controls (TD). Pupil size was measured using the Tobii X2-30 Eye Tracker. The results showed that autistic adults had larger maximal pupil sizes, smaller minimal pupil sizes, and greater change rates of pupil size, particularly during the RMET Eyes task. Clinical correlations revealed that attention switching difficulty positively correlated with mean pupil size in TD participants, while social communication deficits positively correlated with mean pupil size in autistic participants. In conclusion, our findings suggest atypical pupillary responses in autistic adults during socio-affective tasks, indicating heightened cognitive demand. Further investigation is necessary to understand the underlying mechanisms and their association with autistic traits.

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.
