In older adults (ranging between ages 54 – 85), studies have consistently found decreased ERN amplitude when compared to young adults (ranging between ages 18–28; Band & Kok, 2000; Falkenstein, Hoormann, & Hohnsbein, 2001; Mathalon et al., 2003; Mathewson et al., 2005; Nieuwenhuis et al., 2002; Themanson et al., 2006). It is important to note, though, that some of these findings may be confounded by behavioral differences, such as decreased accuracy in older adult groups (Band & Kok, 2000; Mathewson et al., 2005; Nieuwenhuis et al., 2002).
