Cue-Triggered Addiction and Natural Recovery

We propose a model of natural recovery, a widespread yet unexplained aspect of addictive behavior, starting from the recent theory developed by Bernheim and Rangel (2004). While the Bernheim and Rangel model generates many distinctive patterns of addiction, it does not explicitly consider pathways to natural recovery. Based on insights from the neurosciences, we introduce an ”implicit cognitive...

Effects of Methadone Maintenance Treatment on Decision-Making Processes in Heroin-Abusers: A Cognitive Modeling Analysis

A B S T R A C TIntroduction: Although decision-making processes have become a principal target of study among addiction researchers, few researches are published according to effects of different treatment methods on the cognitive processes underlying decision making up to now. Utilizing cognitive modeling method, in this paper we examine the effects of Methadone maintenance treatment (MMT) on ...

Computational Models of Incentive-Sensitization in Addiction: Dynamic Limbic Transformation of Learning into Motivation

Incentive salience is a motivational magnet property attributed to rewardpredicting conditioned stimuli (cues). This property makes the cue and its associated unconditioned reward ‘wanted’ at that moment, and pulls an individual’s behavior towards those stimuli. The incentive-sensitization theory of addiction posits that permanent changes in brain mesolimbic systems in drug addicts can amplify ...

Stress increases cue-triggered "wanting" for sweet reward in humans.

Stress can increase reward pursuits: This has traditionally been seen as an attempt to relieve negative affect through the hedonic properties of a reward. However, reward pursuit is not always proportional to the pleasure experienced, because reward processing involves distinct components, including the motivation to obtain a reward (i.e., wanting) and the hedonic pleasure during the reward con...
