Scientific background

Cognitive Bias Modification - A Cheap and Effective Help to Quit Smoking Cognitive Bias Modification is the new treatment tool for anxiety, depression and addiction this Milliennium. It is based on the changing of automatic unconscious biases in thinking. Emily Holms of Oxford University calls it a cognitive vaccin. (1)

Alcohol Addiction Addictions are seen as neurocognitive development disorders. Recent evidence showes that computerized training interventions with Cognitive Bias Modification (CBM) can reverse some of the underlying processes. A replication study with alcoholic patients reported again, after treatment with CBM, at one year follow up alcohol avoidance behaviour and lower relaps rates. Older patients benefitted more than younger ones. In the first study of Wiers the participants had to push away pictures of alcohol with a joystick during 4 sessions of 15 minutes, in the study of Eberl during12 sessions, without much difference.(2) In a study to assess the optimum number of sessions 6 session seemed the average optimum (3)

Smoking Another study by Reinout Wiers showed that automatic approach tendencies are also present in smokers. (4) A trial to study the effect of CBM in non-quitting smokers was registered in 2014 (5)

Quitty is a game, based on CBM and NLP. The game was tested in a small group of non-quitting smokers All smokers who played at least 5 days for 15 minutes were smoking less cigarettes after the first week.
