Samenvatting
A recent review of research investigating the potential effect of mobile phone use on a concurrent driving task, noted that not only were comparisons between handheld and hands-free operation confounded through critical shortfalls in experimental and statistical control, but also that only one study conducted in 1969 specified the use of a manual transmission vehicle (RoSPA, 1997). This paper details a series of controlled and wholly repeated measures studies, examining kinesthetic and cognitive interference resulting from handheld and hands-free mobile phone use whilst driving simulated vehicles with manual and automatic transmission. The concomitant effects on driving performance are discussed. (Author/publisher)
