Sensory Stimulation During Simulated Driving

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

About this study

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.

Treatment and study plan

Fragrance

Other

peppermint, rosemary, and zest/pulp will increase memory recall for navigation and improve reaction times for braking, compared to performance during unscented conditions

Primary outcomes

  1. Navigation Assessment

    Time frame: 30 minutes

    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.

Secondary outcomes

  1. Braking Assessment

    Time frame: 15 minutes

    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

  2. Workload and mood assessment

    Time frame: 5 minutes

    participants will be asked to rank their perceived mental, physical, and temporal demands in combination with their performance, effort and frustration

  3. Scent assessment

    Time frame: 5 minutes

    A short fragrance questionnaire will be given after each study session, in order to ensure that participants are able to distinguish between non-scented and scented conditions
