Dopamine reward prediction error coding
Reward prediction errors consist of the differences between received and predicted rewards. They are crucial for basic forms of learning about rewards and make us strive for more rewards-an evolutionary beneficial trait. Most dopamine neurons in the midbrain of humans, monkeys, and rodents signal a reward prediction error; they are activated by more reward than predicted (positive prediction er...
متن کاملReward Prediction Error in Online Game Trades
We use trade data from an online game economy to test the dopaminergic reward prediction error (DRPE) hypothesis: upon buying a game item at a price which is obviously too low, a player should become more active in the trading market. We find that players are more willing to buy goods in the in-game market after such an trade incident. Hence, the effect predicted by the DRPE model is visible. Y...
متن کاملDopamine, Reward Prediction Error, and Economics∗
The neurotransmitter dopamine has been found to play a crucial role in choice, learning and belief formation. The best developed current theory of dopaminergic function is the “reward prediction error” hypothesis that dopamine encodes the difference between the experienced and predicted “reward” of an event. We provide axiomatic foundations for this hypothesis to help bridge the current concept...
متن کاملReward Prediction Error Signals are Metarepresentational
Although there has been considerable debate about the existence of metarepresentational capacities in non-human animals and their scope in humans, the well-confirmed temporal difference reinforcement learning models of rewardguided decision making have been largely overlooked. This paper argues that the reward prediction error signals which are postulated by temporal difference models and have ...
متن کاملEye Field Encodes Reward Prediction Error
The outcomes of many decisions are uncertain and therefore need to be evaluated. We studied this evaluation process by recording neuronal activity in the supplementary eye field (SEF) during an oculomotor gambling task. While the monkeys awaited the outcome, SEF neurons represented attributes of the chosen option, namely, its expected value and the uncertainty of this value signal. After the ga...
