Effects of Simulator Practice and Real-World Experience on Cell-Phone—Related Driver Distraction

OBJECTIVE: Our research examined the effects of practice on cell-phone-related driver distraction. BACKGROUND: The driving literature is ambiguous as to whether practice can reduce driver distraction from concurrent cell phone conversation. METHODS: Drivers reporting either high or low real-world cell phone usage were selected to participate in four 90-min simulated driving sessions on successive days. The research consisted of two phases: a practice phase and a novel transfer phase. RESULTS: Dual-task performance deficits persisted through practice and transfer driving conditions. Moreover, groups reporting high and low real-world experience exhibited similar driving impairments when conversing on a hands-free cell phone. CONCLUSIONS: These data indicate that practice is unlikely to eliminate the disruptive effects of concurrent cell phone use on driving. APPLICATION: Multiple regulatory agencies have considered, or are currently considering, legislation to restrict in-vehicle cell phone use. Findings reported herein may be useful to inform these public policy decisions.
