Because functionally distinct theta and delta components have been shown to have unique contributions to the FN-P3 complex, we sought to evaluate whether these measures, and their associated phase dynamics, would be similarly observed for an N2-P3 complex observed in a go/no-go task. Positive findings would provide two new pieces of information. First, this would extend previous work from gambling feedback data, and suggest that separable yet overlapping theta and delta processes are active during response inhibition. Second, if the theta/delta phase dynamics are shown to underlie the go/no-go N2 and P3, as was shown for the FN and feedback-P3, this would support the suggestion that this dynamic may be at work more generally in common ERP measures and could be important to evaluate across data from other experimental paradigms. To assess this, the current study compared TF theta and delta measures with conventional time-domain N2 and P3 ERP measures in data from a go/no-go task using the TF-PCA approach described above (Bernat et al., 2005), in the same manner as applied previously to gambling feedback data (Bernat et al.,
