Objective: This study examines the relationship between the Stroop and driving simulator performance in older adult and younger adult populations. Method: Participants in the older adult group consisted of 9 males and 16 females with an average age of 61.44 (SD = 7.148). Participants in the younger adult group consisted of 17 males and 41 females with an average age of 20.45 (SD = 1.912). The data was derived from an on-going de-identified database of normal adults. Results: A Pearson correlation was conducted between scores on the Stroop and driving errors for both of the age groups. No significant correlations were found within the young adult group. Within the older adult group, at p < 0.05, Simulator Lane Excursions was significantly correlated with Stroop Word T (r = −0.458) and Stroop Color T Score ( r = −0.517), Total Tickets/Violations with Stroop Word T Score (r = −0.433) and Stroop Color T (r = −0.508), as well as Total Collisions with Stroop Color Word T (r = −0.482). Conclusion: Results revealed significant inverse relationships between the Stroop scores and various errors on the driving simulator within an older adult population but not within a younger adult group. As scores on the Stroop increase, an individual's driving errors decrease. This reinforces a relationship between an individual's concentration, speed, and their ability to switch between cognitive tasks and driving abilities. The results also suggest that this relationship is only present in an older adult population but not in the younger population, possibly because of more variability in older adults.
