Cognitive decline resulting from Dementia of Alzheimer’s Type (DAT) can lead to reduced
ability to perform complex daily tasks required for independent living, including driving an automobile.
This study explores the ability of untrained observers to classify driving safety using short video
clips of simulated driving through intersections; it also examined whether untrained observers could
predict whether the driver was cognitively healthy or cognitively impaired. Participants (n = 54) were
shown a series of 30 video clips arranged in an online survey and asked to answer questions following
each clip regarding the safety of the maneuver and the cognitive status of the driver. Results showed
that participants’ subjectively rated DAT drivers as significantly less safe in comparison to control
drivers, F (1, 52) = 228.44, p < 0.001. Participant’s classification of DAT drivers and controls was also
significantly higher than chance (i.e., >50% correct). Findings provide preliminary support for the
development of a clinical decision-making aid using video replay of driving simulator performance
in fitness-to-drive assessments for individuals with cognitive impairment.
