Аннотация:We used the Stop-signal task, standard Stroop task and Stroop task complicated with the requirement to inhibit the response to the word 'Red' (NoGo condition) in 26 subjects. Comparison of the ERPs recorded to the word regardless of congruence in the Stroop task with NoGo condition revealed significant (p < 0.05) differences in 200–300 and 400–500 ms latencies, especially in the lead F3. There were differences between the Go and NoGo conditions at the same latencies in the Stop-signal. The mean RT in this task was less than in the Stroop task with NoGo (the difference was 41 ms), although a correlation (+0.64) of the both RTs was found. This is consistent with the finding, that the latency in differences in the late ERPs components in the Stop-signal (after 300 ms) is lower than in the Stroop task with inhibition (after 400 ms). The study was supported by RFBR project No. 13-06-00553.
