“…It is known that increased age can contribute to changes in information processing speed and executive function. Most studies on post-error slowing reported that slowing occurs in both young and older adults (Pereiro, Bustamante, Cisneros, & Juncos-Rabadán, 2018;Czernochowski, 2014;Ruitenberg, Abrahamse, De Kleine, & Verwey, 2014;Dutilh, Forstmann, Vandekerckhove, & Wagenmakers, 2013;Jackson & Balota, 2012;Friedman, Nessler, Cycowicz, & Horton, 2009;Nessler, Friedman, Johnson, & Bersick, 2007;Falkenstein, Hoormann, Christ, & Hohnsbein, 2000), with significantly increased post-error slowing in older compared to young participants in some of the studies (Pereiro et al, 2018;Ruitenberg et al, 2014;Dutilh et al, 2013;Jackson & Balota, 2012;Friedman et al, 2009;Falkenstein et al, 2000). Based on the aging literature, age may not account for the lack of a post-mismatch button press delay in our study, but, other than age, we are not aware of major differences in our experimental task design and that of Iwanaga and Nittono (2010).…”
