Webbrecent evidence for a dissociation of “liking” and “wanting” in drug addiction, known as the incentive sensitization theory (Robinson and Berridge 1993). We also make the case that sensitization of the “wanting” system and the resulting disso-ciation of “liking” and “wanting” occurs in both gambling disorder and food addiction.
