Abstract [en]

The literature suggests that ocular diseases are negatively related to driving performance. The factors associated with safe driving is discussed and perceptual abilities are suggested to be related to crash involvement. The present study will focus on i) perceptual tasks or reaction time tasks and ii) attentional and cognitive tasks. All tasks will be visual and cognitive demanding and the objective is to understand how different visual cognitive tasks are related to driving performance. The motive is to be able to discriminate between safe versus unsafe drivers with visual deficits but also understand how different mental mechanisms are related to safe, or unsafe, driving.

The reaction time tasks are interesting since the reaction time of participants in the study can be measured when performing the driving task. The participants’ reaction time when an object is possible to detect can be measured i) within the complex driving scenario as well as in tasks ii) mimicking driving and iii) “regular” computerized reaction time tasks such as the Simon task. Hence, the objective is two-folded to develop a simulator based method able to discriminate between safe versus unsafe drivers (among the visual deficit population). Second, to pinpoint the importance of visual reaction time and different cognitive tasks on driving performance.

The cognitive, attentional demanding tasks are not as analyzed at this point but will be elaborated on in the presentation. The tasks are presented in the method section.

The summarised data on patients with Glaucoma, Cataract, age-related macular degeneration (AMD), and diabetic retinopathy reveal, on a general level, is that ocular diseases impair driver performance.  The literature also suggests, for instance, that not all Glaucoma patients fail on-road driving tests. In summary, the majority of the research literature results indicate, a) general decline in driving performance due to a visual impairment, but b) this is not true for all patients with the same visual deficit.
