%X Passengers have the opportunity to influence the driver's situation awareness and promote safer performance. This paper reports an investigation into the influence of passengers on driver situation awareness. 40 two-person teams performed an interactive verbal task, while one team member also undertook a simulated driving task. Half of the drivers were paired with driving-experienced passengers; the others took part with driving-novice passengers. Dependent variables were Verbal Response Time (conversation modulation) and Situation Awareness. <br><br>RESULTS indicated that driving-novice passengers engaged in relatively more conversation than the driving-experienced passengers. Significant differences were found for total Situational Awareness between driving-experienced and driving-novice groups. Further analysis suggested that both experienced drivers and passengers had significantly better Situational Awareness of perceptual factors than driving-novices. Further, Verbal Response Times were found to be significantly predictive of Situational Awareness. <br><br>FINDINGS provide some support for the notion that passengers may have a positive effect on driver's attention in spite of their verbal interactions.<p /> <p>Language: en</p>
