Fixation patterns of learner drivers with and without cerebral palsy (CP) when driving in real traffic environments

Among learner drivers with cerebral palsy (CP), driver education is problematic for those failing to fulfil their education as well as for those becoming licensed drivers. A crucial ingredient in the development of driving is the quality of the visual search. Problems increase for CP learners in those parts of training where high demands are set on visual search abilities. The aim of the study was to increase knowledge about search patterns among learners with CP in comparison with learners and experienced drivers without CP. The study was carried out in traffic by measuring eye movements and the duration and distribution of fixation. The results show that search strategies among learners with CP were less flexible than in the control groups. The results suggest a need for better methods for teaching CP learners search strategies and may provide a tool for such development.
