The influence of emotions on decision -making is largely ignored. The studies of decision-making in neurological patients who can no longer process emotional information normally suggest that people make judgments not only by evaluating the consequences and their probability of occurring, but also and even sometimes primarily at a gut or emotional level. OUTSTANDING QUESTIONS what specific parameter s of decision contexts are encoded by the brain? how are these parameters represented and processed at the neural level? To what extent do such representations correspond to the parameter s of decision -making frameworks? What is the relationship between these representations and cognitive and emotional processes? DECISION MAKING UNDER UNCERTAINTY Minimal parameters: a basic tradeof f between expected reward and risk Choosing between putting money into a savings account or the stock market Expected utility (risk is implicit) vs. financial decision theory UNCERTAINT Y PARAMETERS EXPERIMENTAL DESIGN NEURAL CORRELATES OF EXPECTED REWARD NEURAL CORRELATES OF RISK CONCLUSIONS, PART 1 the brain decomposes risky choice contexts along the statistical dimensions that are the cornerstone of financial decision theory, a paradigmatic cost -benefit and cognitive computation However, these are paradigmatic emotion/affective regions (including insula) At the level of reward/risk perception, no need for speed/accuracy tradeof f ETHICS AND THE BATTLE BET WEEN EMOTION AND REASON MORAL DECISION MAKING Emotion – reason distinction central to classical and contemporar y debates Kant (cognitivism) vs. Hume (moral sentimentalism) Kohlberg ‘s cognitivist moral developmental psychology (moral reasoning) vs. Gilligan Contemporary moral intuitionism (Haidt) HAIDT’S SOCIAL INTUITIONISM Julie & Mark Family Dog 4 reasons to doubt the causal importance of reason Dual process problem Motivated reasoning problem Post hoc problem (objective reasoning a cognitive illusion) The action problem DUAL SYSTEMS ETHICAL POSITIONS Consequentialism Mill's utilitarianism An action is right if it promotes the best consequences.

JOHN STUART MILL GREENE MORAL PHILOSOPHY Scenarios that probe moral intuition. Much used in moral philosophy One of the most famous is the “trolley” dilemma A runaway trolley is about to kill 5 people a) Push lever to change track -- kill 1 to save 5. b) Push man down foot bridge -- kill 1 to save 5.
