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.
