This study investigated whether the event-related brain potentials (ERPs) in go/no-go tasks were modulated by the processing of facial expressions. The ERPs were recorded from 13 participants performing emotional (with happy and angry faces) and nonemotional (with letter stimuli) go/no-go tasks. Results showed that go responses to facial expressions were slower than those to letter stimuli. The no-go-trial-ERPs between 220-320ms after the stimulus onset were more negative than the go-trial-ERPs, but in the smile-go/anger-no-go task, this difference reduced in amplitude in the latency range of 220-260ms. Possible differences of no-go potentials between emotional and non-emotional go/no-go tasks were indicated.
