PS260 Chapter Notes - Chapter 12: Confirmation Bias, Representativeness Heuristic, Orbitofrontal Cortex
Document Summary
Elliot had damage to the orbitofrontal cortex and so he seemed to have lost his emotions. Decisions often involve some element of risk (will the dinner taste as good as the menu implies?) Emotion also plays a role in evaluating our options. In choosing which restaurant we evaluate how each one makes us feel. Detecting covariation: a relationship between two variables such that the presence of one variable can be predicted from the presence of the other. If it is positive, then increases in one variable occur when increases in the other variable occur. If it is negative then decreases in one variable occur when increases in the other occur. (e. g. : exercise and risk of heart attacks covary negatively because exercise strengthens the heart muscle, decreasing the risk) (e. g. : exercise and stamina covary positively since as exercise increases, so does stamina. ) Illusions of covariation: some people detect covariation even where there is none.
