- •
We investigate the effect of target probability on the pre-stimulus ERP.
- •
The BP was larger for frequent targets and the right pN was larger for rare target.
- •
The BP and the pN could be ERP indices of the speed–accuracy system.
- •
The BP could be related to the subjective baseline of perceptual decision.
- •
The pN could be related to the threshold response setting in decision-making.
