Prefrontal Cortex (DLPFC) and the Orbito Frontal Cortex (OFC). It is not so<br />

much the late maturation <strong>of</strong> these areas in itself, but rather the late<br />

maturation <strong>of</strong> these areas in combination with the earlier maturation <strong>of</strong> other<br />

brain areas, including the sub-cortical areas related to motivation and<br />

emotion such as the amygdala and the nucleus accumbens. The slowly<br />

maturing prefrontal systems are supposed to have an inhibitory function on<br />

emotional and motivational systems. It is thought that because <strong>of</strong> this<br />

imbalance <strong>young</strong> people are relatively speaking: impulsive, have an<br />

inclination towards sensation seeking, prefer immediate rewards, have a<br />

greater sensitivity to peer influences and find it difficult to plan ahead.<br />

Adolescents however, do not seem to be less rational than adults are when<br />

reflecting on their own capabilities. This is to say, both <strong>young</strong> <strong>drivers</strong> and<br />

middle-aged <strong>drivers</strong> tend to overestimate their own driving capabilities.<br />

Young <strong>drivers</strong> also do not underestimate known risks when they have the<br />

time to reflect on these risks. When asked for, they will tell that drinking and<br />

driving is dangerous. The problem is that although they know the risks<br />

(when asked for), at least some <strong>of</strong> them still will take the risks.<br />

Although both <strong>young</strong> female <strong>drivers</strong> and <strong>young</strong> male <strong>drivers</strong> are<br />

overrepresented in crashes, the <strong>young</strong> driver problem is predominantly a<br />

<strong>young</strong> male driver problem. The pace at which the volume <strong>of</strong> gray matter<br />

declines (until well into the third decade <strong>of</strong> life) and the volume <strong>of</strong> white<br />

matter increases (during the second decade <strong>of</strong> life), differs between <strong>young</strong><br />

females and <strong>young</strong> males. Decrease in gray matter makes information<br />

processing more effective and increase in white matter makes information<br />

processing faster. Because <strong>of</strong> these differences in pace, <strong>young</strong> females mature<br />

earlier than <strong>young</strong> males. Not only the brain matures at a different pace in<br />

<strong>young</strong> females and in <strong>young</strong> males, also the hormonal regulation starts to<br />

differ considerably between boys and girls when they get into puberty. The<br />

effect <strong>of</strong> the different pace in brain development and differences in hormonal<br />

regulation affecting the cortical and sub-cortical areas, could explain the<br />

greater self-control over emotional behaviour and a lower tendency for<br />

sensation seeking in <strong>young</strong> females than in <strong>young</strong> males.<br />

7.2.2. Social and cultural aspects <strong>of</strong> being <strong>young</strong><br />

The social and cultural aspects <strong>of</strong> being <strong>young</strong> cannot be isolated from the<br />

biological aspects <strong>of</strong> being <strong>young</strong>. It is both 'nature' and 'nurture' and the<br />

interaction between the two. Motives for driving and having a car can be<br />

different for <strong>young</strong> <strong>drivers</strong> compared to middle-aged <strong>drivers</strong> and may differ<br />

across lifestyle groups. For many <strong>young</strong> <strong>drivers</strong> a car is not only a means <strong>of</strong><br />

transport to travel from A to B without the inconveniences <strong>of</strong> public<br />
