CONCEPT
Incentive Salience
Berridge's technical term for the motivational force that transforms neutral stimuli into objects of desire — the pull that makes a cue grab attention, trigger approach, and flood consciousness with the sense that this thing, right now, is worth pursuing. Not reasoned preference. Neural magnetism.
Incentive salience is the process by which the mesolimbic dopamine system tags cues with motivational urgency. When a cue has been paired with reward — particularly variable reward — it acquires incentive salience, which manifests as three measurable properties: automatic attentional capture (the cue grabs attention without conscious effort), approach motivation (the organism moves toward the cue), and consummatory motivation (the organism is driven to engage with the cue to obtain the associated reward). Berridge places "wanting" in quotation marks to distinguish the technical sense from everyday usage; incentive salience is wanting in the technical sense. It is pre-reflective, can override cognitive evaluation, and is not proportional to actual hedonic value. The system is attracted to uncertainty. It is maximally activated by cues that sometimes deliver enormously and sometimes deliver nothing.

The experimental signature of incentive salience is dissociation from knowing.
