Face individual identity recognition: a potential endophenotype in autism / Ilaria MINIO-PALUELLO in Molecular Autism, 11 (2020)
[article]
Titre : Face individual identity recognition: a potential endophenotype in autism Type de document : Texte imprimé et/ou numérique Auteurs : Ilaria MINIO-PALUELLO, Auteur ; Giuseppina PORCIELLO, Auteur ; Alvaro PASCUAL-LEONE, Auteur ; Simon BARON-COHEN, Auteur Article en page(s) : 81 p. Langues : Anglais (eng) Mots-clés : Autism Emotion recognition Endophenotype Face memory Heterogeneity Individual identity recognition Prosopagnosia Social memory Theory of mind Neuroelectrics, Neosync, NovaVision, Magstim, and Cognito and is listed as an inventor on several issued and pending patents on the real-time integration of transcranial magnetic stimulation with electroencephalography and magnetic resonance imaging. The other authors declare no competing interests. Index. décimale : PER Périodiques Résumé : BACKGROUND: Face individual identity recognition skill is heritable and independent of intellectual ability. Difficulties in face individual identity recognition are present in autistic individuals and their family members and are possibly linked to oxytocin polymorphisms in families with an autistic child. While it is reported that developmental prosopagnosia (i.e., impaired face identity recognition) occurs in 2-3% of the general population, no prosopagnosia prevalence estimate is available for autism. Furthermore, an autism within-group approach has not been reported towards characterizing impaired face memory and to investigate its possible links to social and communication difficulties. METHODS: The present study estimated the prevalence of prosopagnosia in 80 autistic adults with no intellectual disability, investigated its cognitive characteristics and links to autism symptoms' severity, personality traits, and mental state understanding from the eye region by using standardized tests and questionnaires. RESULTS: More than one third of autistic participants showed prosopagnosia. Their face memory skill was not associated with their symptom's severity, empathy, alexithymia, or general intelligence. Face identity recognition was instead linked to mental state recognition from the eye region only in autistic individuals who had prosopagnosia, and this relationship did not depend on participants' basic face perception skills. Importantly, we found that autistic participants were not aware of their face memory skills. LIMITATIONS: We did not test an epidemiological sample, and additional work is necessary to establish whether these results generalize to the entire autism spectrum. CONCLUSIONS: Impaired face individual identity recognition meets the criteria to be a potential endophenotype in autism. In the future, testing for face memory could be used to stratify autistic individuals into genetically meaningful subgroups and be translatable to autism animal models.
