Within-subject correlations between an ERP component (ORN, P400a [250–350 msec], P400b [350–450 msec]) and a behavioral measure (response judgment [RJ], RT, and d′ [DP]). Significance of the relationship was assessed by a one-sample t test. Within-subject correlations are also displayed separately for each group: younger musicians (YM), younger nonmusicians (YN), older musicians (OM), and older nonmusicians (ON).

*Musicians > Nonmusicians (p > .05).

**p < .0001.
