Secondary task and risky driving behavior: a test of the mediating effect of situation awareness

Hartono B., Gozali M.

International Journal of Occupational Safety and Ergonomics

2015

Vol. 21, No. 3

399--404

A theoretical model is developed by using a contingency perspective to hypothesize the relationship between a secondary task and risky driving behavior. It is conjectured that the relationship between the two variables is mediated by situation awareness (SA). An experiment is designed and administered to provide empirical evidence. Thirty Indonesian students as subjects were required to carry out a driving assignment in a simulated environment. Empirical evidence suggests that SA provides a partial mediation effect towards the relationship between a secondary task and risky driving behavior. It is also found that a secondary task has a significant effect on risky driving behavior. The secondary task also becomes a significant explanation of SA. In addition, working memory capacity, experience and gender are found to have no significant impact towards SA.
