text messaging during simulated driving
Drews et al. (2009) evaluated the effects of text messaging while driving a xed-base driving simu-
lator, with three screens providing approximately 180 forward degree eld of view. They compared
performance of 40 participants while driving (single task) and driving and text messaging (dual
task). The participants drove in the right lane of a 51-km (32-mile) simulated multilane rural and
urban beltway. During each trial, the participants followed a pace car that was programmed to brake
at 42 randomly selected intervals and would continue to decelerate until the participant depressed
the brake pedal, at which point the pace car would begin to accelerate to the normal freewa ...
