“The scientists immediately discovered a strong neural signal that drove many of the investment decisions. The signal was fictive learning.”
“Montague wanted to know which part of the dopamine system was distorted in the addicted brain. He began to wonder if addiction was, at least in part, a disease of fictive learning. Addicted smokers will continue to smoke even when they know it’s bad for them. Why can’t they instead revise their models of reward?”
ABSTRACT:
A Neural Substrate of Prediction and Reward
Wolfram Schultz, Peter Dayan, P. Read Montague *
The capacity to predict future events permits a creature to detect, model, and manipulate the causal structure of its interactions with its environment. Behavioral experiments suggest that learning is driven by changes in the expectations about future salient events such as rewards and punishments. Physiological work has recently complemented these studies by identifying dopaminergic neurons in the primate whose fluctuating output apparently signals changes or errors in the predictions of future salient and rewarding events. Taken together, these findings can be understood through quantitative theories of adaptive optimizing control.
