Visual attention and older drivers: the contribution of inhibition of return to safe driving

Exp Aging Res. 2006 Apr-Jun;32(2):119-35. doi: 10.1080/03610730500511918.

Abstract

Increasing data suggest that visual attention may be impaired in some older drivers, and that such impairment may be related to poorer driving abilities and a higher crash risk. Because effective scanning of the environment is important for safe driving, the authors sought to examine the relationship between a reflexive visual attention mechanism and driving. To examine this issue the authors conducted a preliminary study using the inhibition of return (IOR) paradigm, which has been labeled as a fundamental search mechanism. Forty-one drivers aged 55 and over completed two on-road driving evaluations and IOR testing. After accounting for the contribution of age, IOR statistically predicted overall driving evaluation scores (p = .045), and the number of errors in scanning the environment (p = .031). To the authors' knowledge these findings represent the first documentation of a relationship between IOR and driving. The results are informative regarding the importance of reflexive visual attention mechanisms towards safe driving.
