Inclusion Criteria

There are 2 groups (1. Addiction group; 2. Control group). Each group consists of 20 participants (male/female, between 18 and 65 years).

Participants of the addiction group must be diagnosed with an addiction disorder/substance dependence (F10.2, F11.2, F13.2, F14.2, F15.2, F16.2, F18.2, F19.2). Furthermore, they must be able to speak German and have to be in treatment at the LVR-Klinik Bonn.

Participants of the control group must speak German or Dutch and have to be students of the Radboud University Nijmegen.

Exclusion Criteria

- Pure cannabis addiction (ICD 10: F12.2) will be excluded, since no long-term WM impairment was found for cannabis (Crean, Crane & Mason, 2011).

- Less than 30 days abstinent: Detoxification can impair cognitive functioning for a couple of days and weeks. To minimize the acute influences of detoxification on cognitive performance, participants of the addiction group must be abstinent for at least 30 days.
