Being the aim of the study to study the Stroop Effect in an emotional task, and compare it with a cognitive task, we conducted an experiment, using ERPs (128 electrodes) and emotional faces of fear and happiness that could be either men or women. In the cognitive task we have conflict using the word MALE or FEMALE. The response was to the gender of the face. The emotional conflict was created by using the words FEAR and HAPPINESS. The response was to the emotion of the face (Egner et al,2008). Results showed a clear main effect of task type and conflict, in the amplitude of the same group of electrodes and within the same time window between 380-690 miliseconds. Latency was influenced only by task type. The emotional task was slower and more positive in central frontal sites than the cognitive task. In central parietal electrodes the emotional task was also slower and more negative than the cognitive task. As for the conflict variable, incongruent trials showed greater negativity in central parietal electrodes and greater positivity in frontal sites than congruent trials. No interaction between types of task and conflict was found.
