Hazard perception is the ability to detect and react to dangerous situations on the road, with reported strong associations with crash involvement (Horswill & McKenna, 2004). The present study investigated the neurocognitive correlates of hazard perception in a population of older adults without dementia. The final sample consisted of 22 males and 42 females between the ages of 60 and 88, X=70.36 (SD=6.88). Participants were screened for dementia using the RBANS. They were also administered a series of neuropsychological measures as well as a Hazard Perception Test (HPT). Better reaction time to touching the target hazards on the HPT was correlated with better performance on Trail Making Test Part B, r = .28, p = .012, Inhibition, r = .22, p = .041 and Switching, r = .23, p = .033 subtests of the Color-Word Interference Test and Useful Field of View part III, r = .28, p = .011. A lower number of errors on the HPT was associated with worse performance on Line Orientation, r =- .22, p = .042, Block Design subtest, r = -.36, p = .002, Trail Making Test Part B, r = .34, p = .003, and Useful Field of View parts II, r = .25, p = .022 and III, r = .28, p = .012. Findings provide preliminary evidence of a relationship between visuospatial/constructional skills, executive functioning and hazard perception in healthy aging older adults. The present study adds to the limited literature on hazard perception in this population and helps guide future research.
