OBJECTIVE The aim of this study was to assess how scrolling through playlists on an MP3 player or its aftermarket controller affects driving performance and to examine how drivers adapt device use to driving demands. BACKGROUND Drivers use increasingly complex infotainment devices that can undermine driving performance. The goal activation hypothesis(More)
Vehicle crashes caused by driver distraction are of increasing concern. One approach to reduce the number of these crashes mitigates distraction by giving drivers feedback regarding their performance. For these mitigation systems to be effective, drivers must trust and accept them. The objective of this study was to evaluate real-time and post-drive(More)
The risk of drivers engaging in distracting activies is increasing as in-vehicle technology and carried-in devices become increasingly common and complicated. Consequently, distraction and inattention contribute to crash risk and are likely to have an increasing influence on driving safety. Analysis of police-reported crash data from 2008 showed that(More)

Recent high profile security breaches have highlighted the importance of insider threat detection systems for cybersecurity. However, issues such as high false positive rates and concerns over data privacy make it difficult to predict performance within an enterprise environment. These and other issues limit an organization's ability to effectively apply(More)
Recent studies focused on driver calibration show that drivers are often miscalibrated, either over confident or under confident, and the magnitude of this miscalibration changes under different conditions. Previous work has demonstrated behavioral and performance benefits of feedback, yet these studies have not explicitly examined the issue of calibration.(More)
Many drivers are miscalibrated, i.e. they think they are better or worse than they actually are at multitasking situations. Recent studies focused on calibration while driving show that drivers are miscalibrated, either over confident or under confident, and that this effect changes under different conditions. Previous work has demonstrated behavioral and(More)
