that in the video clips no visible other road user will start to act dangerously<br />

(overt hazards) and no other road user will suddenly appear on collision<br />

course from behind an object that blocks the view (covert hazards). After<br />

each short video clip and the screen has turned black, participants are asked<br />

what could likely have happened that did not happen and if it had happened<br />

would have been a real threat. When participants watch the video clips their<br />

eye movements are recorded with an eye tracker. In order to test the<br />

emotional and motivational aspect <strong>of</strong> hazard <strong>anticipation</strong>, participants watch<br />

photographs taken from the driver's perspective. There are three categories<br />

<strong>of</strong> photographs: safe situations (i.e. no imminent or latent hazard present),<br />

potentially hazardous situations (i.e. containing a latent hazard that can be a<br />

covert latent hazard or an overt latent hazard) and hazardous situations (i.e.<br />

contain an imminent hazard). Based on other hazard <strong>anticipation</strong> tasks in<br />

which photographs <strong>of</strong> traffic situations were used (Huestegge et al., 2010;<br />

Kelly et al., 2010), it is expected that <strong>novice</strong> <strong>drivers</strong> and experienced <strong>drivers</strong><br />

will not differ in the skill to detect and recognize both imminent hazards and<br />

latent hazards on snapshots if they have the time to watch these snapshots.<br />

Whereas detection and recognition is supposed not to differ, it is expected<br />

that <strong>young</strong> <strong>novice</strong> <strong>drivers</strong> are willing to take more risks than older <strong>young</strong>er<br />

<strong>drivers</strong> in the depicted situations. Participants are asked what their action<br />

would be if they were the driver: do nothing (in case the situation is<br />

considered as safe), release the throttle (in case the situation is considered to<br />

contain a latent hazard), or brake (in case the situation is considered to<br />

contain an imminent hazard). Responses are risky when in case <strong>of</strong> a<br />

photograph with an imminent hazard, the response is 'release throttle' and in<br />

case <strong>of</strong> a photograph with a latent hazard, the response is 'do nothing'. The<br />

response is very risky when in case <strong>of</strong> a photograph with an imminent<br />

hazard the response is 'do nothing'. Responses are cautious when in case <strong>of</strong> a<br />

photograph <strong>of</strong> a safe situation, the response is 'release throttle' and in case <strong>of</strong><br />

a photograph with a latent hazard, the response is 'brake'. The response is<br />

very cautious when in case <strong>of</strong> a photograph with a safe situation the<br />

response is 'brake'. While participants study the static traffic scenes, their eye<br />

movements are recorded.<br />

The specific hypotheses are:<br />

1. Young <strong>novice</strong> <strong>drivers</strong> and older <strong>novice</strong> <strong>drivers</strong> with almost no driving<br />

experience score equally low on a hazard <strong>anticipation</strong> task with the<br />

emphasis on the cognitive aspect <strong>of</strong> hazard <strong>anticipation</strong> (detection,<br />

recognition and prediction);<br />
