T-tests comparing mean amplitude N2, P3 across automated (APPEAR), and manual (Manual) processing. Cohen’s d value was calculated for each comparison. The mean, M, and standard deviation, SD, measurements are in μV.

N2	APPEAR M (SD)	Manual M (SD)	Mean comparison
Fz	1.09 (1.09)	1.33 (1.37)	t(7) = 1.03, p = 0.34, d = 0.19
FCz	1.32 (1.25)	1.54 (1.66)	t(7) = 1.01, p = 0.35, d = 0.14
Cz	1.50 (1.87)	1.30 (1.46)	t(7) = −0.96, p = 0.37, d = 0.12
