Same same but different: the case of olfactory imagery

Abstract
In the present work we present an overview of experimental findings corroborating olfactory imagery observations with the visual and auditory modalities. Overall, the results indicate that imagery of olfactory information share many features with those observed in the primary senses although some major differences are evident. One such difference pertains to the considerable individual differences observed, with the majority being unable to reproduce olfactory information in their mind. Here, we highlight factors that are positively related to an olfactory imagery capacity, such as semantic knowledge, perceptual experience, and olfactory interest that may serve as potential moderators of the large individual variation.

Understanding Olfactory Imagery: A New Perspective
Overview/Introduction
Have you ever tried to imagine a smell in your mind? While visual and auditory imagery—imagining sights and sounds—are well-studied, olfactory imagery, or the ability to imagine smells, is less understood. This research explores how olfactory imagery compares to visual and auditory imagery, highlighting significant differences and factors that influence our ability to imagine smells.
Methodology
The study involved reviewing experimental findings that compare olfactory imagery with visual and auditory modalities. Researchers examined how people imagine smells and identified factors that might affect this ability. They also explored how olfactory imagery functions in people with normal smell perception versus those with smell loss.
Key Findings
- Similarities and Differences: Olfactory imagery shares some characteristics with visual and auditory imagery. However, a key difference is the large variation in people's ability to imagine smells. While most people can easily visualize images or hear sounds in their mind, fewer can do the same with smells.
- Individual Differences: The capacity to form olfactory images varies greatly among individuals. Factors such as semantic knowledge (understanding the meaning of smells), perceptual experience, and interest in odors can enhance one's ability to imagine smells.
- Impact of Smell Loss: People with olfactory loss (anosmia) struggle to form olfactory images similar to those with normal smell perception. Interestingly, the longer someone experiences smell loss, the more their brain activity changes, suggesting a gradual memory loss of olfactory representations.
Implications
- Practical Applications: Understanding olfactory imagery could improve fields like flavor and fragrance design, where imagining smells is crucial. It could also aid in developing therapies for those with smell disorders.
- Enhancing Olfactory Imagery: Activities that boost semantic knowledge and perceptual experience, such as learning to identify and name odors, might improve olfactory imagery abilities.
Limitations
- Individual Variation: The study highlights significant individual differences in olfactory imagery capacity, which can complicate generalizations. More research is needed to understand why some people are better at imagining smells than others.
In conclusion, while olfactory imagery shares some features with visual and auditory imagery, it is unique in its variability among individuals. Factors like knowledge and experience play a crucial role, and understanding these can help harness the potential of olfactory imagery in various applications.
