Abstract Details

142 college students participated in a study of simulated driving. The aim of the study was to investigate situational and personality factors that may influence risk-taking in states of moderate stress and fatigue, within the general framework of the transactional model of stress. An attempt was made to induce a state of fatigue in half the participants, by forcing them to evade a series of other vehicles and pedestrians that threatened to collide with the driver. Following the induction, drivers were afforded opportunities to pass other traffic in risky circumstances. In fact, the fatigue induction proved to be ineffective: all participants, irrespective of experimental condition, tended to respond to the simulated drive with moderately elevated levels of distress and fatigue. By contrast, personality factors linked to aggression and anxiety were predictive of both subjective response and objective performance indices related to risk-taking, such as frequency of passing other vehicles. The investigation of personality focused on the role of coping, including both typical or dispositional coping style, and the situational coping elicited by the actual drive. Dispositional coping predicted increased subjective distress and worry, and loss of task engagement. Consistent with the transactional model of driver stress, the effect of dispositional coping was largely mediated by the situational strategies adopted in response to the specific situation. Task-focused coping appeared to be more adaptive than emotion-focused coping. Dispositional coping factors, especially a confrontive coping dimension, predicted risk-taking behaviors such as frequent passing. These effects were not mediated by situational coping, suggesting that emotions experienced during the acquisition of driving skills may shape habitual behavioral styles that operate irrespective of current mood and coping strategy. Implications of the findings for countermeasures to driver stress are discussed.
