Accounting for Subjectivity in Experimental Research on Human Olfaction

Area of Science:

• Neuroscience
• Psychology
• Sensory Science

Background:

• Olfaction exhibits significant interindividual perceptual differences.
• Subjective experience in olfaction has been largely neglected in contemporary research.
• Recent advances in consciousness research offer potential methods for studying subjectivity.

Purpose of the Study:

• To advocate for the inclusion of subjective reports in olfactory research.
• To propose methodological adaptations from consciousness studies for olfactory research.
• To enhance the understanding of odor perception diversity and its neural underpinnings.

Main Methods:

• Reviewing and adapting methodologies from consciousness research.
• Developing protocols for rigorous acquisition of subjective olfactory reports.
• Integrating subjective data with neural mechanism investigations.

Main Results:

• Proposed methods enable rigorous collection of subjective olfactory data.
• The adapted methodologies are suitable for studying individual differences in olfaction.
• This approach facilitates deeper insights into the neural basis of odor perception.

Conclusions:

• Incorporating subjective reports is crucial for a comprehensive understanding of olfaction.
• Methodological innovation can bridge the gap between objective measures and subjective experience in smell research.
• This research paves the way for future studies on the neural correlates of individual olfactory perception.
