Perceived Workload and Performance in the Presence of a Malodor
As part of an olfactory adaptation experiment, researchers collected NASA Task Load Index (TLX) data from United States Military Academy cadets who completed two complex tasks in either the presence or absence of a simulated malodor. Results showed that participants exposed to the odor twice tended to show a decrease in perceived mental demand during the second task. Furthermore, these participants also showed a higher correlation coefficient between decrease in mental demand and improvement in task performance. Taken together, these results indicate a possible link between olfactory adaptation and perceived mental demand, at least in the presence of a malodor.
