Figure 1.

Pictorial representation of the modified version of the Stroop task used in the study. Participants could only respond to three ink-colors: red, green, or purple. For the incongruent-eligible condition (third box) the word was one of the ink-colors that the participant could respond with (red, green, or purple) but printed in an incongruent ink-color (such as GREEN printed in red ink). For the incongruent-ineligible condition (fourth box), the word could be any color-word other than red, green, or purple printed in an incongruent ink-color (such as the word BLUE printed in red ink).Reprinted from Prakash et al.
