About

The purpose of this study is to examine the effect of three specific odors on simulated driving performance. It is hypothesized that the presence of peppermint, rosemary, and zest/pulp will increase memory recall for navigation and improve reaction times for braking, compared to performance during unscented conditions

Full description

This study will examine the effect of scented odors on the attention and behavioral performance of healthy young adult and older adult drivers. Past research indicates that specific scented odors (i.e., peppermint and cinnamon) enhance motivation, performance and alertness, decrease fatigue and stimulate the central nervous system in a variety of contexts. The current study will examine the effect of three different odors on simulated driving as participants perform navigation and braking scenarios. This study will be the first of its kind to elucidate the association between specific scents and performance gains in simulated driving. The data will serve as proof-of-concept for eventual patient focused interventions relative to sensory stimulation and driving.
