Young drivers are specifically poor at maintaining attention to the forward roadway while driving. Additionally, drivers are poorly calibrated to their own abilities, often overestimating their driving skills. The current research examines the effect of FOCAL on a young driver’s calibration using two different measures, normalized difference scores and the Brier score. Thirty-six participants received either FOCAL or Placebo training program, immediately followed by driving simulator evaluation of their attention maintenance performance. In the evaluation drive, participants had driven through four scenarios in a driving simulator with their eyes tracked. Participants were asked to perform a mock visual search task on a tablet simulating an infotainment in-vehicle system while driving in each scenario. After each drive, participants filled out a questionnaire for the Brier score. Once all drives were complete, the participant filled out one final questionnaire used for the normalized proportion of glances. FOCAL trained drivers performed better than Placebo trained drivers on attention maintenance and were greater calibrated using the normalized proportions measure. The brier score measure did not find any significant differences. Theoretical and practical implications and future directions are discussed.
