Addiction-Stroop color match-to-sample task paradigm.
Participants matched the color of a color sample to that of a target word by pressing a YES key for color matches and a NO key for color nonmatches. The task had three conditions for word content (Stroop): (1) color words (neutral), (2) alcohol words (alcohol), and (3) cannabis words (cannabis). (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
