Driver Perception & Attention
Implicit & explicit processes in behavioural adaption
2005 Masters' Thesis by B Lewis-Evans |
Behavioural adaptation is the finding that road safety interventions often have unanticipated (& contrary) consequences e.g. road width, delineation, brake lights, ABS
Theoretical question whether behavioural adaptation is due to explicit decisions (risk) or implicit perceptions (affordances)
Simulator-based study manipulating road width and measuring driver speeds, lane positions, judgements of safety, relative risk, and driving difficulty
Results showed that speeds reliably decreased with road width, without any explicit awareness of changes in road width changes in risk & preference are retrospective
