The sense of smell has a powerful influence over our emotions, memories and reactions. For children with profound learning and communication difficulties, smell can help them identify people, places and objects. So, given that olfactory information has a direct path to our limbic system, can it be positively harnessed in an educational environment? A new study aims to explore not only how multisensory impaired (MSI) children use their sense of smell, but also whether olfactory cues can improve their understanding, communication and ability to make choices. Here, the authors review the approach, considerations and initial findings of the study—as well as the potential long-term implications for fragranced products of the future.
