Reward uncertainty enhances incentive salience attribution as sign-tracking.
Conditioned stimuli (CSs) come to act as motivational magnets following repeated association with unconditioned stimuli (UCSs) such as sucrose rewards. By traditional views, the more reliably predictive a Pavlovian CS-UCS association, the more the CS becomes attractive. However, in some cases, less predictability might equal more motivation. Here we examined the effect of introducing uncertaint...
متن کاملThe Incentive Salience of Alcohol
Results: Findings indicate that the C allele of rs2023239 is associated with greater CB1 binding in the prefrontal cortex, greater alcohol cue–elicited brain activation in the midbrain and prefrontal cortex, greater subjective reward when consuming alcohol, and more positive outcomes after treatment with a medication that targets the mesocorticolimbic neurocircuitry. In addition, there were str...
متن کاملIncentive Salience and the Transition to Addiction
Most adults have used a potentially addictive drug at least once in their lifetime, if caffeine, alcohol, and nicotine are included in addition to illicit drugs. In some cases, contact with a substance is so frequent and socially accepted that many in society fail to recognize it as a “drug.” However, relatively few people develop sufficient problems with drug use to meet the formal criteria fo...
متن کاملA Neural Computational Model of Incentive Salience
Incentive salience is a motivational property with 'magnet-like' qualities. When attributed to reward-predicting stimuli (cues), incentive salience triggers a pulse of 'wanting' and an individual is pulled toward the cues and reward. A key computational question is how incentive salience is generated during a cue re-encounter, which combines both learning and the state of limbic brain mechanism...
متن کاملA computational substrate for incentive salience.
Theories of dopamine function are at a crossroads. Computational models derived from single-unit recordings capture changes in dopaminergic neuron firing rate as a prediction error signal. These models employ the prediction error signal in two roles: learning to predict future rewarding events and biasing action choice. Conversely, pharmacological inhibition or lesion of dopaminergic neuron fun...
