We have shown that evoked mean spectral power (ERSP) and ITC vary by developmental period vis-à-vis reward vs. non-reward (no win) processing. The meaning of these age related correlates still requires further study. For instance, as developmental trends, they may relate to greater efficiency of processing feedback, but they could also be associated with aspects of greater reward sensitivity or risk taking proclivity (Galvan et al., 2006). As noted by Casey et al. (2008), there is a relative paucity of research focused on the role of the frontal cortex and, more specifically, the functional interaction it has with subcortical reward circuitry with respect to risky behavior. Future studies should consider these functional relationships and how they vary across individuals, such as adolescents showing high levels of sensation-seeking (Mackiewicz Seghete, Cservenka, Herting, & Nagel, 2013).
