Abstract

To travel safely, drivers must detect imminent collisions. Older drivers have more accidents per miles driven than younger drivers, potentially reflecting age differences in judgments about collision. Prior studies measured age differences in judgments about when a collision would occur (time to contact). Older adults made greater underestimations, but this would lower their risk for accidents. Judgments about when a collision would occur must be preceded by judgments about whether a collision would occur (Presented at the Annual Meeting of the Human Factors and Ergonomics Society (2001) Minneapolis). Results of the present study indicated that judgments about potential collision were less accurate for older drivers compared with younger drivers. This would increase their risk for accidents. Age differences in driver performance may be associated more with age differences in judgments about whether a collision would occur than with age differences in judgments about when a collision would occur. Age differences in judgments about potential collision suggest a new avenue to pursue in an account of differential accident rates in older and younger drivers.
