The experiment investigates the effect of perceived control on risk taking
in a dynamic, everyday task. Using established and validated video simulati
on techniques, the risk-taking preferences for 96 drivers were measured for
a range of driving activities (speed choice, following distance, gap accep
tance, and overtaking). The perceived control manipulation was as follows:
Half of the participants were told to imagine they were driving the vehicle
, and the other half were told to imagine they were passengers. Those who w
ere told to imagine they were driving chose significantly faster speeds tha
n did those who were told to imagine they were passengers. Differences for
the other risk-taking measures were not significant. For speed choice, it c
ould be argued that an illusion of control was in operation, such that thos
e who were in control (i.e., drivers) were comfortable with a higher level
of risk than those who were not in control (i.e., passengers).
