The present paper focuses on ERP data recorded during a number of different speeded response tasks, including the Erikson Flankers task, the Simon task, color Stroop task, and the Go/No-Go task. In the arrows version of the Erikson Flankers task, participants respond to the direction of a central arrowhead which is flanked by either compatible (e.g., < < < < <) or incompatible (e.g., < < > < <) arrowheads (Eriksen & Eriksen, 1974). Similarly, in the Simon task, participants respond to a red circle with their left index finger and to a blue circle with their right index finger (Simon, 1969). Stimuli are presented either to the right or to the left of the center fixation cross, leading to congruent (e.g., red circle on the left side) or incongruent (e.g., red circle on the right side) trials. In the color Stroop task, names of colors are presented on a screen and participants are asked to respond to the color of the word. On congruent trials, the color of the target word matches the word (i.e., the word “red” is
