Étude comparative du lexique olfactif d’enfants neurotypiques et d’enfants présentant un Trouble du Spectre Autistique

Abstract : Numerous studies underline the particular relationship that children with an Autism Spectrum Disorder have with language, as well as with sensoriality; however, few have linked these two major components of autism. We therefore wanted to analyze the lexical richness that an autistic child can produce when he is exposed to odors’ names.
Our main research objective was to identify the number of significant terms mentioned by a child with ASD with olfactory hyper-sensoriality when he is told names of odorants, and to compare his results with those of a neurotypical child. These children were both male and aged around 8 years old Our secondary objective was to check whether there could be a link between the number of terms related to an odorant and the hedonic value that the child could give to this same odorant, especially in the case of ASD. We asked each of the children to tell us how much they appreciated each odor mentioned, by referring to a scale of hedonicity for more clarity and precision.
Our results have highlighted a difference in the elaboration of the lexicon related to the olfactory field in favor of the autistic child, who has used more significant terms and more varied grammatical natures than the neurotypical child. Finally, concerning hedonicity, this is not correlated with the lexical richness in the case of our subjects, and cannot be considered as reliable for the autistic child, this one granting a strong positive valence to items being difficult to tolerate on a daily basis. These results underscore the need for further research into the influence of sensoriality on verbal and non-verbal communication in children with ASD, and to consider this influence both in speech therapy and in everyday life.
