Adolescence is a critical time in a person’s life, which is the period extending from the onset of puberty to early adulthood (12 – 18 years of age) (Lefton & Brannon, 2006). It is during this time that key developmental tasks of adolescence are experienced, such as cognitive development, psychological development, acquisition of ones self identity and of course physical maturation (Lefton & Brannon, 2006). During Adolescence the brain undergoes many structural changes as demonstrated by MRI studies, these studies especially show significant changes in the parietal and frontal regions of the brain along with a pronounced decline of gray matter volume during adolescence as opposed to childhood (Choudhury, Blakemore & Charman, 2006). White matter is seen as increasing throughout adolescence into adulthood in the prefrontal and parietal cortex (Choudhury, Blakemore & Charman, 2006). It is these biological changes that assist developmental changes, as it is due to these regions that a high level of cognitive abilities take place (Blackmore, Ouden, Choudury & Frith, 2007). These cognitive abilities include that of executive function, which is “skills that enable the control and coordination of thoughts & Behaviours” and mentalising, the ability to manipulate and understand other people’s intentions (Choudhury, Blakemore & Charman, 2006, p. 166; Blackmore, et al, 2007). Autonomy is another crucial part of adolescence and involves three separate domains these being behavioural, cognitive and affective domains (Parra & Oliva, 2009).
