Abstract
Researchers have observed poor driving performance among those who have sustained an ABI, compared to their pre-morbid selves and healthy controls. Because of the role that attention plays in driving, attentional impairment typically observed after an ABI may contribute to this driving deficit. Eye glance is a well-established measure of visual attention. The current study sought to evaluate participants' glances while driving, comparing those with ABI to a healthy control group on two conditions: baseline and performing a secondary task. During all driving conditions, the ABI had more overlong glances than the HC group. Both ABI and HC groups had more glances away during the task condition than during baseline. There were also significant interactions of group x driving condition. Results showed that group and task affected the frequency of long glances away from the road, but secondary task performance had greater effects on glances of the ABI group than on the HC group. A secondary aim of this study was to compare performance on traditional neuropsychological tests to eye glances, a more ecologically valid measure of attention. The lack of many significant correlational findings are likely due to the complexity of the construct of attention, and the contributions of other cognitive abilities to tests and during driving. This study showed that ABI have poorer glance behavior than HCs during driving, but additional research is necessary to determine the implications of these findings.
