AgeLab on BBC's "Surviving A Car Crash"
The AgeLab was featured on BBC’s Horizon in “Surviving A Car Crash”. AgeLab Researcher Bryan Reimer discusses driver stress and cognitive distraction. He explains the relationship that exists between workload and performance and how this relationship relates to automotive safety and crash prevention. Research Associate Katie Godfrey has a test subject drive the MIT AgeLab’s instrumented 2010 Lincoln MKS on the highway while performing moderately demanding cognitive tasks to increase the subject’s stress levels. The test demonstrated that as workload and stress increase, so do the driver’s heart rate and other measures of physiological arousal. In addition, changes in the subject’s gaze with increased cognitive demand suggests a restriction in how visual attention is allocated to the activities on the roadway.
