The positive results in the current report strengthen the notion that theta and delta phase dynamics play a crucial role in the morphology of ERPs, often obscuring effects observed in traditional time-domain component measures, and bolster the view that time-frequency analyses may offer an important new look at traditional time-domain component measures from condition averaged ERP data. The standard N2 and P3 measures observed here did not accurately characterize the multiple processes occurring during (i.e., theta and delta) related to response inhibition which occurred during the ERP window, similar to what was shown for the FN and P3 components during a gambling feedback task (Bernat et al., 2011). This bolsters the idea that superimposed theta and delta processes may underlie ERP components across a broad array of tasks. In detail, the rapid oscillatory rise and fall of theta activity corresponds to a polarity-shift from a negative deflection during the N2 to a positive deflection at the P3, while delta contributes a unidirectional positivity throughout the ERP response. Moreover, in the current report, regression models indicated that theta and delta contributed
