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
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.

| Navigation Assessment | The navigation task will consist of up to six blocks of instruction/recall segments that will contain the same number of turns over the same distance, but with novel environmental stimuli and a randomized order of turns unique to each block. | 30 minutes |
| Measure | Description | Time Frame |
|---|---|---|
| Braking Assessment | a virtual stop sign will appear suddenly in the middle of the visual field. The participant will be instructed to come to a stop as quickly as possible and to remain stopped until the stop sign disappears | 15 minutes |
| Workload and mood assessment |
