Does peer passenger influence on male adolescent drivers ' visual scanning behavior during simulated driving?
The presence of a male peer passenger was associated with a reduction in the visual scanning range of male adolescent drivers. This reduction could be a result of potential cognitive load imposed on the driver due to the presence of a passenger and the real or perceived normative influences or expectations from the passenger.
In contrast to findings in mice, the results of this study exclude a role for DNMT1 gene copy number in susceptibility to neoplastic transformation in humans.
