Internal noise estimates correlate with autistic traits / Greta VILIDAITE in Autism Research, 10-8 (August 2017)
[article]
Titre : Internal noise estimates correlate with autistic traits Type de document : Texte imprimé et/ou numérique Auteurs : Greta VILIDAITE, Auteur ; Miaomiao YU, Auteur ; Daniel H. BAKER, Auteur Article en page(s) : p.1384-1391 Langues : Anglais (eng) Mots-clés : internal noise neural noise double-pass sensory autism quotient decision making Index. décimale : PER Périodiques Résumé : Previous neuroimaging research has reported increased internal (neural) noise in sensory systems of autistic individuals. However, it is unclear if this difference has behavioural or perceptual consequences, as previous attempts at measuring internal noise in ASD psychophysically have been indirect. Here, we use a “gold standard” psychophysical double-pass paradigm to investigate the relationship between internal noise and autistic traits in the neurotypical population (n?=?43). We measured internal noise in three tasks (contrast perception, facial expression intensity perception, and number summation) to estimate a global internal noise factor using principal components analysis. This global internal noise was positively correlated with autistic traits (rs?=?0.32, P?=?0.035). This suggests that increased internal noise is associated with the ASD phenotype even in subclinical populations. The finding is discussed in relation to the neural and genetic basis of internal noise in ASD.
