  • Title: Interaction between visual status, driver age and distracters on daytime driving performance.
    Author: Wood J, Chaparro A, Hickson L.
    Journal: Vision Res; 2009 Aug; 49(17):2225-31. PubMed ID: 19559721.
    Abstract:
    This study investigated the effects of visual status, driver age and the presence of secondary distracter tasks on driving performance. Twenty young (M=26.8years) and 19 old (M=70.2years) participants drove around a closed-road circuit under three visual (normal, simulated cataracts, blur) and three distracter conditions (none, visual, auditory). Simulated visual impairment, increased driver age and the presence of a distracter task detrimentally affected all measures of driving performance except gap judgments and lane keeping. Significant interaction effects were evident between visual status, age and distracters; simulated cataracts had the most negative impact on performance in the presence of visual distracters and a more negative impact for older drivers. The implications of these findings for driving behaviour and acquisition of driving-related information for people with common visual impairments are discussed.
