“…As stimuli are typically presented outside the focus of attention, the MMN is suggested to capture automatic pre-attentive discrimination processes (Näätänen et al, 2007). Associations between higher intelligence and larger (i.e., more negative) MMN amplitudes have been observed in multiple studies (De Pascalis et al, 2014;De Pascalis & Varriale, 2012;Houlihan & Stelmack, 2012;Sculthorpe et al, 2009;Troche et al, 2009Troche et al, , 2010 as well as a relation between higher intelligence and shorter MMN latencies (De Pascalis et al, 2014;De Pascalis & Varriale, 2012;Sculthorpe et al, 2009). However, associations were mostly of moderate effect size (~ r = -.15 to r = -.42) and different studies also failed to find respective relations (e.g., Bauchamp & Stelmack, 2006;De Pascalis & Varriale, 2012;Troche et al, 2010), suggesting a more heterogeneous picture.…”
