that study (Chorlian et al., 2015), as described in section 3.1, informed the analysis employed in the present study. The developmental trajectories (time-series) of the association between KCNJ6 gene variants and theta band EROs during the P3 response to targets in adolescents and young adults are measured by the effect size of the genetic variants in a non-parametric regression model of the theta band EROs. These associations are described as a function of age, sex, task modality, and scalp location. The current study is not designed as a replication of the adult study; 19% of the subjects included in this study were subjects in Kang et al. (2012). This is the first developmental study of neurophysiological function that characterizes trajectories of the genetic association of task-related electrophysiological activity with specific SNPs.
