Rapid neural categorization of angry and fearful faces is specifically impaired in boys with autism spectrum disorder / Stephanie VAN DER DONCK in Journal of Child Psychology and Psychiatry, 61-9 (September 2020)
[article]
Titre : Rapid neural categorization of angry and fearful faces is specifically impaired in boys with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Stephanie VAN DER DONCK, Auteur ; Milena DZHELYOVA, Auteur ; Sofie VETTORI, Auteur ; Soha Sadat MAHDI, Auteur ; Peter CLAES, Auteur ; Jean STEYAERT, Auteur ; Bart BOETS, Auteur Article en page(s) : p.1019-1029 Langues : Anglais (eng) Mots-clés : Autism electroencephalography facial emotion processing fast periodic visual stimulation implicit expression detection Index. décimale : PER Périodiques Résumé : BACKGROUND: Difficulties with facial expression processing may be associated with the characteristic social impairments in individuals with autism spectrum disorder (ASD). Emotional face processing in ASD has been investigated in an abundance of behavioral and EEG studies, yielding, however, mixed and inconsistent results. METHODS: We combined fast periodic visual stimulation (FPVS) with EEG to assess the neural sensitivity to implicitly detect briefly presented facial expressions among a stream of neutral faces, in 23 boys with ASD and 23 matched typically developing (TD) boys. Neutral faces with different identities were presented at 6 Hz, periodically interleaved with an expressive face (angry, fearful, happy, sad in separate sequences) every fifth image (i.e., 1.2 Hz oddball frequency). These distinguishable frequency tags for neutral and expressive stimuli allowed direct and objective quantification of the expression-categorization responses, needing only four sequences of 60 s of recording per condition. RESULTS: Both groups show equal neural synchronization to the general face stimulation and similar neural responses to happy and sad faces. However, the ASD group displays significantly reduced responses to angry and fearful faces, compared to TD boys. At the individual subject level, these neural responses allow to predict membership of the ASD group with an accuracy of 87%. Whereas TD participants show a significantly lower sensitivity to sad faces than to the other expressions, ASD participants show an equally low sensitivity to all the expressions. CONCLUSIONS: Our results indicate an emotion-specific processing deficit, instead of a general emotion-processing problem: Boys with ASD are less sensitive than TD boys to rapidly and implicitly detect angry and fearful faces. The implicit, fast, and straightforward nature of FPVS-EEG opens new perspectives for clinical diagnosis.

Images of neutral faces were presented at 6 Hz, periodically interleaved with fearful expressions at 1.2 Hz oddball rate. While both groups equally display the face inversion effect and mainly rely on information from the mouth to detect fearful expressions, boys with ASD generally show reduced neural responses to rapid changes in expression. At an individual level, fear discrimination responses predict clinical status with an 83% accuracy. This implicit and straightforward approach identifies subtle deficits that remain concealed in behavioral tasks, thereby opening new perspectives for clinical diagnosis.
