Table 1_The sound of smell: crossmodal correspondences between sound and odor.docx

Sounds and smells, in particular, might co-occur in our daily lives (e.g., spraying a perfume), yet their interaction remains underexplored. Understanding how these modalities interact can inform multisensory design and sensory marketing.

This study investigates whether affects indirectly mediate crossmodal associations between sounds and odors.</p>Methods<p>We conducted three experiments. In Experiments 1 and 2, 61 and 60 participants respectively classified 80 sounds and 24 olfactory ingredients according to eight affective categories: Apathy, Depression, Happiness, Irritation, Relaxation, Sensuality, Stimulation, and Stress. In Experiment 3, 62 participants directly matched 5 groups of sounds to 5 groups of odors, selected based on the results of the first two experiments.
