Imagine walking into a room and, without realizing it, sensing fear through smell. This could change how you communicate with others. While it is known that we rely on body language and facial expressions to understand others, smell might also play a role. Previous lab-based research has shown that people can detect fear in body odours. By combining psycholinguistic experiments and virtual reality interactions during exposure to fear-related smells, this project takes the next step to uncover how smells affect language processing in interactions. Investigating how smells interact with real-world communication holds promises for therapy, education, and virtual environments.
