TL;DR: These results substantiate the key neural substrates underlying reactivity to drug cues and drug craving and identify brain regions that are consistently activated by presentation of drug cues.

TL;DR: A human devaluation-transfer procedure in which young adult smokers were first trained on a concurrent choice task to earn tobacco and chocolate points before one outcome was devalued by specific satiety or health warnings against consumption of that outcome indicated that choice was controlled by an expectation of outcome value, that is, was goal-directed.

TL;DR: A proposed theoretical synthesis may account for the contributions of appetitive and aversive motivational processes involved in self-regulatory conflicts to AB and it yields testable predictions about the conditions under which AB should predict and have a causal influence on future consummatory behavior.

TL;DR: A novel application of incentive learning theory is proposed which posits that depressed smokers experience greater increases in the expected value of smoking in the face of these three motivational states, which promotes goal-directed choice of smoking behavior over alternative actions.

TL;DR: Although initial drug seeking is goal‐directed, chronic drug exposure confers a progressive loss of control over action selection by specific outcome representations (impaired outcome devaluation and specific transfer), and a concomitant increase in control overaction selection by antecedent stimuli (enhanced habit and general transfer).
