Driving experience, attentional focusing, and the recall of recently inspected events

How does a driver’s perception of roadway events change with experience? A laboratory study addressed this question by comparing novice and experienced drivers as they watched video recordings taken from a moving vehicle. While watching the recordings, the drivers had their eye movements monitored. When the recording was paused, memory for immediately prior events was tested, and recall performance related to what the viewer had been inspecting. The recordings were taken from a vehicle as it travelled along a series of roads, and questions were asked about other road users and about roadway features. The experiment asked about the relationship between driving experience and attentional capture, and about the recall of events recently seen. What attracted attention were objects of central interest such as other road users appearing close to the camera, and moving objects. When the memory test was administered immediately after a hazardous event had occurred, such as a pedestrian stepping into the path of the camera vehicle, then there was evidence of attentional focussing and reduced availability of details about incidental objects. Recall performance generally reflected the pattern of eye fixations, but viewers did not always recall details about fixated objects, and were sometimes able to recall information about objects that were not fixated. Experienced drivers recalled more of the incidental events than the novices, but they were similar in their recall of central events. This supports the association between driving experience and the extent of the effective perceptual field.
