Alertness Maintaining Task (AMT): Effects on Driving in Healthy Aging and Mild Cognitive Impairment

Negative effects on driving accuracy and safety have been clearly demonstrated during conditions of distraction or when drivers are engaged in a competing task (e.g., cell phone use). However, more recent studies suggest that certain types of cognitive tasks (Alertness Maintaining Tasks, AMTs) can be used in situations of driving fatigue to actually increase alertness and reduce driving errors in younger drivers. Although the use of AMTs holds promise in this area, research on the effects of these tasks on driving performance in older drivers or drivers with pre-existing cognitive impairment has not been completed. A better understanding of the possible utility of AMTs in these two populations is clearly important, given these individuals' higher risk for driving errors and crashes. This pilot proposal compares three groups of individuals (young, healthy old, patients with mild cognitive impairment) using a STISIM driving simulator for an extended period of time to induce fatigue, followed by alternating driving and driving plus AMT conditions. The trivia-based AMT used in this proposal is presented via a Ford Automotive Sync System to allow for auditory task presentation and verbal responding. Participants also will undergo heart rate monitoring while using the STISIM, a brief neuropsychological test battery, and self report measures of fatigue and performance to better understand possible group differences. This project will combine efforts from the Department of Psychiatry, School of Engineering and Ford Automotive Company. The data from this pilot study will be used for future larger scale collaborative studies.
