“…Recent studies using large samples suggest an error rate of around 20% is typical (Ettinger et al, 2003a(Ettinger et al, , 2005bSmyrnis et al, 2002; Tatler & Hutton, in submission; see also Everling & Fischer, 1998). Error rates are not constant across the lifespan, being highest during childhood, reaching a nadir during early adulthood and then increasing very slowly with advancing age until around 60, when the rate of increase appears to accelerate (Fischer, Biscaldi, & Gezeck, 1997;Klein & Foerster, 2001;Olincy, Ross, Youngd, & Freedman, 1997). The developmental profile of antisaccade errors is thus broadly consistent with the known development of the prefrontal cortex.…”
