Intérêt de l’olfaction pour favoriser l'accès lexical chez l’adulte déficient intellectuel

Abstract : The present study investigates the contribution of olfactory inputs to lexical access. It is based on the results of a naming task, given to ten adults with intellectual disability, aged from 2 to 6.5 (lexical age of acquisition). Could olfaction help these people during rehabilitation? Indeed, disability often implies a need to anchor thought in perception. Olfaction, between emotions and memory, could be an interesting rehabilitation tool. The participants are shown seven pictures of objects and their corresponding smell, separately at first and then altogether. The efficiency of both procedures as far as the access to lexicon is concerned, is compared analyzing the answer score, the response time and the number of produced words. This workshop is conducted with a group of ten intellectually disabled people and a group of ten neurotypical children of same sex and same lexical age of acquisition. The compared results highlight that the number of words produced by a person with intellectual disability gets better with olfactory and olfactory-visual aid. This is in opposition to the results achieved with only visual help or the results of the non-disabled children. Odor naming performances seem to improve with age. Qualitatively, odors appear to give more enjoyment to this population. These results are compared with current data available in specialized literature.
