Attentional and approach biases in adolescents with a cannabis use disorder. (A) Attentional bias (in seconds) for cannabis words significantly differed from attentional bias for alcohol words (p = 0.008). A positive score indicates that participants were slower in naming the colour of substance-related words compared to neutral words. (B) Approach bias (in milliseconds) for cannabis, alcohol, appetitive and neutral pictures did not significantly differ. A positive score indicates that participants were faster in pulling (approach) compared to pushing (avoidance) the joystick for that picture category. Average (bar) and individual (dots) bias scores are depicted in both figures.
