“…Most current research on RT-ability correlations emphasizes the role of one or more lower-order constructs in explaining the relationship. The most prominent account appeals 2 of 18 | MCKINNEY aNd EULER to variation in neural information processing speed (Jensen, 2006) and is supported by an inverse relation between cognitive ability and ERP latencies (Bazana & Stelmack, 2002;Beauchamp & Stelmack, 2006;Jaušovec & Jaušovec, 2000;de Pascalis, Varriale, Fulco, & Fracasso, 2014;de Pascalis, Varriale, & Matteoli, 2008;Schubert, Hagemann, Voss, Schankin, & Bergmann, 2015;Troche, Houlihan, Stelmack, & Rammsayer, 2009). Indeed, one recent study suggested that variation in the speed of later ERP components (the P200 and later) can explain more than 80% of the variance in general intelligence using factor analytic approaches (Schubert, Hagemann, & Frischkorn, 2017).…”
