Hazard anticipation of young novice drivers - SWOV

• The video task and the photo task have concurrent validity. If these
tasks have concurrent validity this would imply that controlled for
exposure, crash free novice drivers have higher scores on both task than
novice drivers that have reported a crash;
• The video task with mouse clicks and the photo task have convergent
validity. If the two tasks have convergent validity this would imply that
the more experienced drivers are the higher their scores on both the
video task and the photo task will be.
As the version of the video task with the mouse clicks failed to discriminate
between learner drivers, novice drivers and experienced drivers (i.e. there
was no convergent validity), an improved version of the video task was
developed. The hypothesis research question in this second study was:
• The improver video task has convergent validity, implying that
professional drivers have higher scores on this improved video task
than learner drivers.
Research that is necessary to test the first hypothesis of the first study (on
concurrent validity) could not be conducted in the second study, as no crash
data were available of the participants in study 2.

The video task
Just as in Chapter 4, animated video clips were developed that contained at
least one latent hazard. Also just as in Chapter 4, a distinction was made
between covert latent hazards and overt latent hazards. Figure 5.1 shows two
screen captures of a developing traffic situation. Both the driver and the lorry
are turning left. The left screen capture is of an earlier moment in time than
the right screen capture. Is the participant aware of the fact that the lorry
blocks her or his view and that another car or motorcycle may suddenly
appear at the position where the cross is put in the right picture? This is the
same situation as depicted in Figure 3.9, but now from the perspective of the
driver.
