Addicted individuals less responsive to reward-anticipation

It may be difficult for addicted individuals to learn when they can expect a reward. This learning problem could perhaps explain why they are more prone to addiction and find it difficult to kick the habit. Researchers at Radboud university medical center and Radboud University reached this conclusion on the basis of an extensive meta-analysis of the brain imaging literature. Their findings will be published in JAMA Psychiatry on 1 February.
