Abstract
In this study, 243 cognitively intact and cognitively impaired older participants’ movement-in-depth (looming) abilities were assessed using a portable device that we had previously developed in our laboratory [4]. Results indicated normative relationships between looming ability and age, looming ability and driving violation records, and age and driving violation records. Findings also confirmed the validity and reliability of the measurements taken with the device. In conclusion, this device may be useful for identifying drivers at risk for rear-end collisions, developing effective training interventions, and creating fair and valid driver licensing tests.
