Table 2.

Mean amplitude of the difference waves (ERPs in switching trials minus ERPs in repetition trials) in the early (230–330 ms) and late (330–430) time window (N = 13).

Time window	230–330 ms		330–430 ms
Electrode	Mean amplitude (μV)	95% CI	Mean amplitude (μV)	95% CI
Fz	1.26	[0.06, 2.46]	0.73	[−0.22, 1.68]
Cz	1.54	[0.19, 2.89]	0.36	[−0.42, 1.14]
Pz	0.67	[−0.51, 1.85]	0.30	[−0.68, 1.27]

Note: the mean amplitudes were derived from ERPs pooled for the two task conditions. CI = confidence interval.
