the middle <strong>of</strong> the piece or play variations on the theme. She thinks that the<br />

performance at the procedural stage is generated by procedural<br />

representations that are simply run <strong>of</strong>f in their entirety (see the concept <strong>of</strong><br />

schemata in Section 3.4). It is only later after more practicing but also because<br />

<strong>of</strong> rethinking <strong>of</strong> what one is actually doing, that one can interrupt the piece<br />

and start at for instance the third bar without having to go back to the<br />

beginning and repeat the entire procedure from the beginning. The ability to<br />

play variations on the theme requires even more practicing and rethinking.<br />

Karmil<strong>of</strong>f-Smit (1992) hypothesised that this is not because <strong>of</strong> improvement<br />

in behavioural mastery but because <strong>of</strong> improvement <strong>of</strong> the mental<br />

representations that generate the skills (i.e. improvement in schemata). This<br />

is what she called the process <strong>of</strong> 'representational redescription'. Suppose<br />

that based on simple representations a driver applies her or his skills more or<br />

less automatically and unexpectedly a dangerous situation occurs. Then the<br />

driver may start to rethink why she or he has applied these skills. The result<br />

<strong>of</strong> this rethinking is that her or his mental representations (schemata) that<br />

generate automatic task execution become more elaborate and flexible.<br />

Studies on differences between experts and <strong>novice</strong>s in detection and<br />

recognition tasks have shown that experts can see patterns and perceive the<br />

underlying structure <strong>of</strong> a situation that <strong>novice</strong>s cannot. When however<br />

confronted with completely novel situations in which even the elaborated<br />

schemata <strong>of</strong> experts are not <strong>of</strong> any help to comprehend the situation,<br />

detection <strong>of</strong> patterns by experts can be worse than detection <strong>of</strong> patterns by<br />

<strong>novice</strong>s (see Chi, 2006 for an overview). Experts spend proportionately more<br />

time on how a novel situation can be comprehended with existing<br />

knowledge and much less time in implementing a strategy for the solution<br />

than <strong>novice</strong>s. This is relevant for hazard detection. The differences between<br />

<strong>novice</strong>s and experts with regard to the detection and recognition <strong>of</strong> potential<br />

hazards are discussed in more detail in Chapter 3.<br />

The conclusion <strong>of</strong> the theory discussed so far is that generally not all topics<br />

relevant for safe driving are addressed in basic driver training. Furthermore,<br />

<strong>of</strong> the skills that are learned such as manoeuvring the vehicle and mastering<br />

common traffic situations, skill performance may look like as if the<br />

procedural stage is reached, but this is probably not true. Of what is<br />

described by Karmil<strong>of</strong>f-Smith (1992) as the process <strong>of</strong> 'representational<br />

rediscription' has presumably not yet started when learner <strong>drivers</strong> pass the<br />

driving test.<br />
