Impacts of sensory multimodality congruence and familiarity with short utilization, on product evaluation and general perceptual comfort

The world is a multi-sensory environment and every event has its multi-faces. However, not all sensory modalities are involved equally to all stimuli: specific cross-modal integration may be particularly pertinent for specific context: for a cosmetic product, touch and olfaction are evidently the two most important senses and their integration plays an important role in perceptual decision making to guide product utilization behavior (Courrèges et al., 2021). While precedent study has just studied the effect of touch-olfaction interaction, which are the mechanisms underpinning these effects are not examined. We hypothesized that each sense, when works alone, can create an expectation of sensory information coming from the other sensory modalities (Damettè et al., 2006) while simultaneously integrated, can evoke a integrated new sensory feature. The whole product appreciation not only depends on the degree of congruence between the modalities but also is a dynamic process depending on the degree of familiarity and affectivity after repeated use. (Sacchetti, Mc Glone et al, 2021)
Precisely, in this study, we shall explore how the touch could create an expectation about other sensory modalities, especially about olfactory perception and inversely, how an olfactory stimulus can evoke the experience of other sensory modalities, and especially about texture expectation. Also we would like to explore how the simultaneous touch - olfactory perception can reinforce emotional experience and global comfort perception. In addition mechanisms such as the degree of congruence between the modalities, familiarity to the product will be studied to examine their contribution to emotional experience of the product.
To answer these questions, 40 people (18-45 years, 20 women among 40) will be recruited and take part in a touch-olfaction interaction experimentation in the laboratory and a follow-up observation of cosmetic products use at home. The touch-olfaction interaction experimentation consists of using 6 perfumes (covers a fairly wide range of perfumes used in the cosmetic) and 4 typical textures used in cosmetic products. To measure the sensory interaction, 1) after having touched each texture or smelled each parfum one series of description tests (from free to indexed descriptions and finally focused either olfactory or texture expectation) should be used and also emotional experience and emotional expectation evoked by these mono-sensory stimulus will be measured. 2) with different combination of touch-olfaction stimuli, participants will assess the emotional experience and global comfort provided by the stimuli and the degree of congruence of the two modalities. The emotional experiences are also assessed with psycho-physiological measures(Gabriel et al, 2021), such Heart Rate change (indicator of emotion, arousal state and information take-in) , Breathing rhythm (co varied with emotion) and facial reactions (explicit and implicit emotional expression) 3) The familiarity influence on the emotional experience will be estimated with a observational measure after a 3 week-utilization of the products. We would like to know after a period of utilization a cosmetic product (one is personally least congruent, another is personally most congruent), how emotional experience evolve and whether the degree of congruence is modified. We predicted that touch and olfaction are not mutually most potential sensory expectation. This gives room of sensory integration plasticity : our progressive inductive description from all sensory modalities to focus on a particular one will impact on their judgement of the degree of congruence. The high congruence will reinforce positive emotional experience and also global comfort while incongruence is an important negative factor on global comfort judgement. However in line with touch-olfaction integration plasticity, we expect to see that after 3 week-utilization in real life conditions, the degree of incongruence will be diminished and also accompanied with an increase of positive emotions.
