This study investigated theta and delta TF activity during a complex response inhibition task, based on previous research demonstrating that indexing theta and delta activity during common ERP component windows measures can offer some important advantages relative the traditional time-domain measures (e.g. FN and P3; Bernat et al., 2011). The positive results from the current study provide information relative to the two primary aims. First, results extend previous work with gambling feedback data to this go/no-go task, revealing that theta and delta measures were both increased for demands of response inhibition, and indexed separable but overlapping processes occurring during conventional electrocortical indices of response inhibition (i.e., N2 and P3). This provides motivation for future work to better understand the functional role of these theta and delta processes during response inhibition and decision making. Second, results bolster the view that indexing these co-occuring but separable processes operating in theta and delta frequency ranges may offer an important new way to look at traditional time-domain component measures based on typical condition averaged ERP data. The current findings support the view that common
