Alerting-induced P2 peak amplitude at different cortical sites (X_ ± SD, μV).

Group	Cues	Prefrontal	Frontal	Frontal-central	Central
Novices	Dual cue	3.43 ± 2.61##	3.98 ± 2.72##	4.19 ± 2.75##	3.83 ± 2.79##
Elites	Dual cue	2.42 ± 1.90	2.61 ± 1.83*	2.70 ± 1.94*	2.30 ± 1.97*
Novices	No cue	0.90 ± 2.59##	1.07 ± 2.56##	1.11 ± 2.49##	1.11 ± 2.18##
Elites	No cue	0.47 ± 1.88	0.56 ± 1.63	0.58 ± 1.59	0.40 ± 1.66

Post hoc comparisons based on Bonferroni correction: compared with the novice group, ^*p < 0.05, ^**p < 0.01; compared with the no-cue condition, ^#p < 0.05, ^##p < 0.01. Significance is based on post hoc comparisons following a significant main effect of group or cue in the 2 (group) × 2 (cue) × 4 (brain region) three-factor mixed-design ANOVA.
