“…In contrast, studies have demonstrated that the anterior N2 in response to perceptually novel stimuli often is not modulated by stimulus context or attention (Chong et al, 2008; Daffner et al, 2000; Schomaker, Roos, & Meeter, 2014; Tarbi et al, 2011), and can be enhanced when novel stimuli occur outside the focus of attention (Schomaker & Meeter, 2014). Moreover, in a study that varied whether frequent standard, rare target, or rare non-target stimuli consisted of simple geometric shapes or highly unusual figures, stimulus frequency and deviance from immediate context were found to have only limited influence over the size of the anterior N2.…”
