Addiction stroop exp

[moses20]

I'm new to Superlab and am trying to design a modified Stroop experiment to assess attentional bias in smokers for smoking related stimuli. I was wondering if anyone has any modified Stroop experiemnts they would be willing to share to give me an idea of the type of format I should be aiming towards? Any type of modified Stroop would be helpful, need not be addiction related.
Thanks

Exists a modified version of stroop called Emotional Stroop for the study of emotional interference. Maybe you can work with cigarrette brands using brands as interference.
