Purpose. The purpose of this study was to examine the effects of iPod interactions on driver performance over several sessions to determine if performance decrements declined with practice. Method . Nineteen younger drivers (mean age = 19.4, range 18 to 22) participated in a six-session study in the University of Calgary Driving Simulator. Drivers encountered a number of critical events on the roadways while interacting with the iPod. Measures of hazard response, vehicle control, eye movements, and secondary task performance were analysed. Results. Increases in perception response time (PRT) and decreases in minimum headway, led to an increase in the number of collisions when difficult iPod tasks were performed. Over the course of the sessions, performance improved in all conditions. Discussion. Responses to common driving hazards were slowed when iPod interactions were being executed. With practice, this effect declined somewhat but the decrement remained relative to the baseline condition.Discussion.
