COGSCI 200 Lecture Notes - Lecture 23: Basal Ganglia, Reinforcement Learning, Expected Utility Hypothesis
Document Summary
Cogsci 200 - morality, free will, & responsibility (part ii) Transform subjective values into an objective internal scale. Prospect theory - theory of how human choice deviates from expected utility theory. Reinforcement learning - learning how to maximize future expected utility. All rewards are internally generated signals computed by the brain, and encompass both extrinsic and intrinsic reward. Ventral-medial and orbital prefrontal cortex and basal ganglia (striatum) represent a final common pathway for the representation of utility (subjective value) Midbrain (dopaminergic) circuits (connecting to basal ganglia) compute reward prediction error signals used in reinforcement learning. Emotion - appraisal theory - understanding the function of emotions. Appraisal - assessments of situations that tell the organism how they relate to current goals and values\ Intuitionist (affective/perceptual) approach - immediate sense about right or wrong when judging the situation. David hume said reason needs to serve the passions. Rationalist approach - calculating & reasoning through problems.
