This document summarizes Brian Knutson's presentation on anticipatory affect and financial risk taking. It discusses how brain regions like the nucleus accumbens and anterior insula that anticipate rewards and losses influence financial decision making. Studies using tasks like the Behavioral Investment Allocation Strategy task show that activity in these regions before choices predicts risk seeking or risk avoiding behaviors. The findings suggest affective processes beyond standard economic models impact financial decisions. Remaining questions concern how other decision systems interact with affective circuits and whether individual level effects translate to groups.
