posted on 25.04.2008, 14:36 authored by Nikolaos Gkikas, John H. RichardsonThis article concisely describes three experiments testing the effects of
auditory/cognitive distraction deriving from levels of conversational demand. In
the pilot study, 8 participants drove three simulated routes with and without the
task of holding a conversation with the experimenter. In the pilot experiment, 8
participants drove three different virtual routes with and without conversing
with the experimenter. In experiment 1, 24 participants drove one virtual route
under three conditions: no interaction with the experimenter, holding an
informal conversation and holding a conversation concerning issues at work.
The same design was repeated in the second experiment, with the difference
that the 12 participants were tested on the Lane Change Task (Mattes, 2003).
The results suggest a significant effect for conversation on driver ability to
control the vehicle laterally, as well as a differentiation between conversation
topics.
