This project was designed to explore the parameters that increase or decrease incidences of Inattentional Blindness, within the context of the driving experience in order to provide evidence for a core underlying cause in “looked-but-fail-to-see†accidents. Participants were presented with a battery of relevant visuo-spatial and cognitive tests. The aim of the project was to explore the cognitive, perceptual and psychological factors that increase or decrease incidences of IB in the laboratory, and are therefore likely to be influential in “looked-but-fail-to-see†accidents on the road.
