“…Odor perceived intensity was determined by the same individuals on a 9-level Likert scale (1 = no odor at all to 9 = extremely strong odor). The concentration of non-commercial odorants was manipulated to select those of medium intensity according to neurotypical judgments ( 33 , 34 ). Eight hedonically contrasted odorants were selected.…”

IntroductionOdors are closely linked to emotions, play an important role in the well-being of individuals and can influence mood. Despite these crucial properties, the hedonic responses to odors of people with profound intellectual and multiple disabilities (PIMD) remain little explored.AimThis within-subjects study aims to examine whether children and young people with PIMD react in a differentiated way to odors evaluated as pleasant or unpleasant by neurotypical adults and, if so, with which behaviors. The influence of their global mood on their emotional responses to odors is also examined.MethodTwenty children and young people (7–18 years old) with PIMD were exposed to four pairs of hedonically contrasted odors. A control stimulus was presented before each odorant. Five emotional responses, one physiological reaction (nausea reactions), and three responses reflecting approach toward or avoidance of the stimulus were recorded throughout the duration of the stimulus exposure. The participants’ global mood status was measured before the start of the research with the French version of the Mood, Interest and Pleasure Questionnaire (Ross and Oliver, 2003).ResultsThe results show that when exposed to pleasant odorants, participants kept their heads aligned with the odorant source longer, smiled longer, and produced more positive vocalizations. In contrast, unpleasant odorants elicit more pouts and grimaces. Nausea reactions occurred in the presence of unpleasant odorants. The hedonic responses were more marked during the second presentation of the stimuli. Participants with a higher MIPQ score showed significantly more emotional reactions to odors.ConclusionThe results confirm the presence of olfactory preferences in participants with PIMD and the existence of a link between their mood, emotions and olfactory hedonic processing. They prompt the use of odors to support not only the cognitive development of this population, but also their mood and their emotional regulation abilities.

“…Finalement, les trois études réalisées ont permis de tester des conditions d'observation des comportements de détection des odeurs avec des personnes polyhandicapées, un apport précieux quand on connait les défis de la recherche impliquant cette population (Petitpierre & Dind, 2023).…”

L’olfaction est une modalité sensorielle cruciale sur le plan cognitif et affectif ainsi que pour la qualité de vie des êtres humains. Cependant, ce sens a longtemps été négligé dans le champ du polyhandicap. Trois études portant sur les habiletés olfactives de 20 à 22 enfants et jeunes polyhandicapés ont permis de mettre en évidence leurs capacités à détecter des odeurs, à manifester des réactions de plaisir ou de déplaisir en fonction de la nature plaisante ou non des odeurs, ainsi qu’à s’habituer à une odeur présentée de manière répétée et rapprochée dans le temps. Ces résultats permettent d’encourager les milieux accompagnant ces personnes à utiliser davantage les odeurs à des fins d’étayage affectif et d’apprentissage.
