The P3 results suggest a multifocal influence of alcohol on cognition, which is supported by later ERP studies examining the effect of alcohol on several cognitive domains, including attention and monitoring, leading to effective performance control. These domains are part of the rubric of executive control, and impairment in these processes has a widespread influence on cognition. Alcohol-induced changes have been reported in components related to visual processing (Colrain et al., 1993; Weschke and Niedeggen, 2012), covert attention (Jaaskelainen et al., 1995; Kenemans et al., 2010), sustained attention (Rohrbaugh et al., 1987), motor preparation (Marinkovic et al., 2000), response inhibition (Easdon et al., 2005), error/action monitoring (Ridderinkhof et al., 2002; Euser et al., 2011), and semantic memory (Marinkovic et al., 2004).
