Research Lecture Series Dr. Steven Savage Presents: How does age affect the contribution of head and eye movements to scanning at intersections?


Please join Dr Steven Savage, as he presents, “How does age affect the contribution of head and eye movements to scanning at intersections?: The lecture will take place on November 27, 2018 as part of the Research lecture Series in Lecture Hall 2. All are welcome to attend. One hour of Mass CE will be awarded. You are invited to join us for a light reception in Conference Room 1 following the lecture.

Abstract: Older drivers are more likely to be involved in collisions at intersections. One reason for this may be that they do not scan their surroundings sufficiently well to detect hazards in a timely manner. Furthermore, there have been conflicting reports regarding older and younger subjects scanning behavior. Some have shown that older subjects make smaller and fewer scans than younger drivers, whereas others have found no age differences. However, in these previous studies scanning behavior was quantified by tracking subjects head movements only. This approach does not capture potential compensatory eye movement behavior. Older subjects may, for instance, make more scans with their eyes only or have a larger eye component to their scans. Therefore, the aim of the current study was to evaluate the effects of age on the relative contributions of both the head and the eyes to overall scan magnitudes at intersections.
