THE EFFECT OF PERSONALITY DIMENSIONS AND SUBJECTIVE EXPERIENCE OF FATIGUE ON TRAFFIC SAFETY

The study deals with problem of correlation between conative personality dimensions and subjective experience of fatigue in professional drivers from the aspect of traffic safety, as well as with alteration of correlation in three time spots: in the beginning, in the middle and in the end of the working day. The sample comprised 107 drivers. Conative dimensions were evaluated by the Cybernetic Battery of Conative Tests KON-6. Subjective experience of fatigue was measured by the Psychological Fatigue Test (PFT). The correlation between conative dimensions and subjective experience of fatigue has shown that the coefficients of Multiple Correlation obtained in all three testings are statistically significant (F1=5.182, F2=6.106, F3=5.783, df=6, p<0.01. We may conclude that except the EPSILON dimension (which is equivalent to Eysenc’s extraversion), all other conative dimensions are in positive correlation with subjective experience of fatigue in all the three time spots of our study.
