Decision making: normative decision theories define how people should make decisions to yield the optimal choice, descriptive decision theories describe the decisions that people actually make. Many of our decisions use heuristics that were shaped by evolution: value and decision making: Economic models view decision making as a way to maximize reward or payoff: shows multiple factors are considered, components of value: Payoff what kind of outcome and how much: primary and secondary reinforcers. Effort or cost how much effort or time will the outcome cost: temporal discounting function. Preference one outcome may be liked more than the other: representation of value: Single-cell recording from three pfc areas in the monkey while the monkey made value decisions: manipulated payoff, probability, and cost.
