less good in hazard <strong>anticipation</strong> than experienced <strong>drivers</strong> are, when they do<br />
not have to drive.<br />
Most <strong>of</strong> the studies on differences in eye movements between <strong>novice</strong> <strong>drivers</strong><br />
and experienced <strong>drivers</strong> while watching videos taken from the driver's<br />
perspective have been carried out at the University <strong>of</strong> Nottingham<br />
(Chapman et al., 2004; Chapman & Underwood, 1998; Crundall et al., 2002;<br />
Underwood, Chapman, et al., 2002). These studies were not about<br />
anticipatory eye glances in situations with latent hazards, but about scanning<br />
patterns on different types <strong>of</strong> road and on fixations in situations with<br />
imminent hazards. A key finding <strong>of</strong> these studies was that also while<br />
watching videos, <strong>novice</strong> <strong>drivers</strong> did not adapt their scan patterns as much to<br />
the type <strong>of</strong> road (rural, suburban and urban) as experienced <strong>drivers</strong> did. A<br />
second key finding was that when there is an imminent hazard, <strong>novice</strong><br />
<strong>drivers</strong> narrowed down there visual search for a longer period to the area<br />
where the imminent hazard was visible than older, more experienced <strong>drivers</strong><br />
did. This is to say they kept staring in the direction <strong>of</strong> the detected hazard<br />
and forgot to look around for other information. From the first key finding<br />
can be concluded that lack <strong>of</strong> adaptation in visual search to the type <strong>of</strong> road<br />
and road environment is not caused by lack <strong>of</strong> attention that is available for<br />
visual search, but is caused by less developed mental models (schemata).<br />
From the second key finding can be concluded that <strong>novice</strong> <strong>drivers</strong> may miss<br />
important information that is necessary to avert the imminent hazard when<br />
this information is in the peripheral field <strong>of</strong> view. The only study found on<br />
hazard perception and differences between <strong>novice</strong> <strong>drivers</strong> and experienced<br />
<strong>drivers</strong> using video clips and eye tracker equipment, not carried out at the<br />
University <strong>of</strong> Nottingham, was a study by Borowsky et al. (2010). In this<br />
study, latent hazards in the video clips were mostly staged in real traffic.<br />
Except for one latent hazard, these latent hazards were overt hazards. There<br />
were no significant differences in eye movements between <strong>novice</strong> <strong>drivers</strong><br />
and experienced <strong>drivers</strong> with regard to the overt latent hazards. One <strong>of</strong> the<br />
staged situations in a video clip was a lead vehicle that suddenly brakes at a<br />
T-intersection (road to the right) because a car approaches the T-intersection<br />
from the right and turns to the right just in front <strong>of</strong> the lead vehicle. From the<br />
driver's perspective in the video clip (the car behind the lead vehicle) the<br />
approaching car from the right cannot be clearly spotted because <strong>of</strong> parked<br />
vehicles. This situation is both an overt latent hazard (a lead vehicle that can<br />
brake) and a covert latent hazard (a possible car from the right that causes<br />
the lead vehicle to brake). In this, situation <strong>novice</strong> <strong>drivers</strong> tended to look only<br />
straight ahead to the lead vehicle whereas experienced <strong>drivers</strong> also looked to<br />
