DROWSINESS AND DRIVING IN A MIDDLE AGED POPULATION
A population of middle aged and older drivers was screened for physical problems or psychological traits that might pre-dispose the individuals toward difficulties in staying alert while driving. The incidence of middle aged and elderly drivers admitting to drowsiness while driving is high. This appears related to maleness, yearly mileage logged, and long trip driving. Cattell personality testing revealed no consistent group of personality traits which correlates with getting drowsy. Subjects who handled drowsiness especially poorly (that is, falling asleep) did show a low factor C which measures emotionality, tendency to worry, give up, and evade responsibility. Many physical factors were examined, but all failed to reveal a consistent pattern of physical defect in the drowsiness group.
