Adolescents’ propensity for risk taking and reward-seeking behavior. Their results revealed greater responses of the nucleus accumbens and amygdala when winning than losing. Whereas adults activated the amygdala, adolescents mostly activated the nucleus accumbens, suggestive of adolescents’ heightened sensitivity to reward more than punishment. Another fMRI study has found that, compared to adults, adolescents showed greater activation in the anterior cingulate, orbitofrontal cortex, and right amygdala in response to viewing fearful faces (McClure et al.2004). Similarly, when viewing subsequently remembered emotion-specific faces, adolescents had different levels of activity in the right temporal lobe, anterior cingulate, and hippocampus compared to adults (Nelson et al., 2003). These studies suggest that adults activate areas related to attentional demands when viewing emotion-laden faces, whereas adolescents spend more energy attending to the emotional content of the faces and consequently activate areas related to affective processing(McClure et al., 2004).
