Purpose: In accordance with aging of populations in many developed countries, number of drivers who suffer from mild cognitive impairment (MCI drivers) is increasing. Since it has been reported that driving skill of the MCI drivers are deteriorated, it is important to train themselves in driving situation to preserve their driving skills. The present study was conducted to develop the simple driving simulator system, and to examine the effect of training in this system. Design/methodology/approach: Nineteen university students (8 males and 11 females) participated in this study. After the habituation period (approximately 5min), three trials (approximately 12 min) were conducted. Experimental situation imitated the real highway course. During trials, dangerous situation that would be resulted in car accident is randomly appeared and participants were required to avoid the car accidents. To avoid the possible car accidents are considered as correct response. Findings: Mean percent of correct responses for male and female were 75.2% and 56.6% in 1st trial and 95.7% and 72.6% in 3rd trial, respectively. Two-way analysis of variance revealed that the main effect of sex (F (1, 14) = 7.84, p < .05) and trials (F (2, 34) = 10.19, p < .001). These results indicate that numbers of car accidents are dramatically decreased and the driving skills of male are superior to that of female. Practical implications: Although the present study revealed the differences in driving skills between the sexes, their driving history was not considered. Driving history of each participant should be examined in future study. Originality/value: Since the improvement of driving skills is revealed, our experimental design is expected as the tool for the preservation of driving skills in the MCI drivers.
