| Annotation | When driving, the ability to detect impending collisions is an important perceptual task. The present study concerns the detection of motion along a straight path during variable speed. Observers were presented with displays simulating a 3-D environment with obstacles in the path of motion. During the trial, observer motion decelerated at a constant rate, and was followed by a blackout prior to the end of the display. On some trials, the rate of deceleration resulted in stopping before the collision, whereas on other trials the rate of deceleration resulted in a collision with the obstacles. The observer's task was to detect which trials simulated an impending collision. The proportion of collision judgements was greater for older as compared with younger observers when a collision was not simulated. Older observers showed less sensitivity to detect collisions than did younger observers, particularly at high speeds. The results suggest that increased accident rates for older drivers may be due to an inability to detect collisions at high speed. (RH). |
