The Power of Labels: Identical Odors Perceived Differently Based on Names

New research reveals that the names we assign to odors can significantly impact how our brains process and perceive them. In an experiment, participants were asked to evaluate the similarity or difference between identical odors based on the labels given to them. Two citrus scents, for instance, were rated as more dissimilar when labeled differently.

Using advanced ultrahigh-field functional MRI technology, researchers were able to observe the brain’s response to these labeled odors in the primary olfactory cortex, the region responsible for processing odors. The findings suggest that the labels we use can influence our perception of odors, providing valuable insights into the complex relationship between language and our sensory experiences.

The study, published in the journal Human Brain Mapping, raises intriguing questions about the context-dependent nature of our sense of smell and the role of language in shaping our daily life. So, would a rose still be as sweet if it were called something else? Or would stinky tofu remain as pungent under a different name? The answer, according to this research, might just surprise you.

Participants in the study were presented with a series of labeled odors, such as minty and citrusy. These odors were scanned using a 7-tesla functional MRI Machine Condition Monitoring, which allowed researchers to observe the brain’s activity in real-time as participants evaluated the similarity or difference between the labeled odors. The results showed that identical odors were processed differently in the brain depending on the labels assigned to them. This research sheds new light on the intricate relationship between language and our sensory experiences, highlighting the importance of considering the context in which we encounter and evaluate odors.
