Fig. 1. Response scores (means and standard errors) of salivary cortisol during experimental days minus comparison day data (raw values depicted for the comparison day). Driving phobics (DP) and healthy controls (HC). Awake = awakening; Pre = 1 hour before; SitA = quiet sitting; Drive1 = driving outbound leg; Drive2 = driving inbound leg; SitB = quiet sitting. Comparison data (nondriving) was collected at the same times as these epochs on the driving days.
