Computer-based Training (Retraining) for People With Gambling Problems

The training program is based upon the approach-avoidance task (AAT) and can be easily performed on a computer, laptop or tablet. There is a total of 20 pictures, 10 slot-machine gambling related pictures and 10 neutral pictures that were already used in a prior study (Wittekind et al., submitted). The pictures appear on the computer screen and have to be either pushed or pulled. Pushing and pulling depends on a masked instruction (not related to the content of the pictures, but to the color of the frame). All gambling-related pictures are framed with the color that is instructed to be pushed, all neutral pictures are framed with the color that is instructed to be pulled.
