Car crashes rank among the leading causes of death in the United States. Acknowledgements We acknowledge the assistance of Founded in 1947, the AAA Foundation in Washington, D.C. is a not-for-profit, publicly supported charitable research and education organization dedicated to saving lives by preventing traffic crashes and reducing injuries when crashes(More)
OBJECTIVE To assess the sensitivity of two physiological measures for discriminating between levels of cognitive demand under driving conditions across different age groups. BACKGROUND Previous driving research presents a mixed picture concerning the sensitivity of physiological measures for differentiating tasks with presumed differences in mental(More)
Although it is speculated that impairments associated with autism spectrum disorder (ASD) will adversely affect driving performance, little is known about the actual extent and nature of the presumed deficits. Ten males (18-24 years of age) with a diagnosis of high functioning autism and 10 age matched community controls were recruited for a driving(More)
Physiological measures provide a continuous and relatively non-invasive method of characterising workload. The extent to which such measures provide sensitivity beyond that provided by driving performance metrics is more open to question. Heart rate and skin conductance were monitored during actual highway driving in response to systematically increased(More)
OBJECTIVE The aim of this study was to assess sensitivity of visual attention and driving performance for detecting changes in driver cognitive workload across different age groups. BACKGROUND The literature shows mixed results concerning the sensitivity of gaze concentration metrics to variations in cognitive demand. No studies appear showing how age(More)
Heart rate and heart rate variability (HRV) measures collected under actual highway driving from 25 young adults were compared to assess the relative sensitivity of each for distinguishing between a period of single task driving and periods of low and high additional cognitive workload. Basic heart rate, skin conductance and most, but not all, of the HRV(More)
Young adults with attention deficit hyperactivity disorder (ADHD) are at higher risk for being involved in automobile crashes. Although driving simulators have been used to identify and understand underlying behaviors, prior research has focused largely on single-task, non-distracted driving. However, in-vehicle infotainment and communications systems often(More)
Young adults with Attention Deficit Hyperactivity Disorder (ADHD) have been shown to be at increased risk for impairment in driving behaviors. While stimulant medications have proven efficacy in reducing ADHD symptomatology, there is limited knowledge as to their effects on driving impairment. The main aim of this study was to assess the impact of(More)
PURPOSE Young adults with ADHD have been shown to be at increased risk for impairment in driving behaviors. Although stimulant medications have proven efficacy in reducing ADHD symptomatology, there is limited knowledge as to their effects on driving behavior. The focus of this report is on assessing the impact of lisdexamfetamine dimesylate (LDX) on(More)
