Preference reversals in decision making under risk are accompanied by changes in attention to different attributes

摘要: Recent work has shown that visual fixations reflect and influence trial-to-trial variability in people’s preferences between goods. Here we extend this principle to attribute weights during decision making under risk. We measured eye movements while people chose two risky gambles or bid on a single gamble. Consistent with previous work, found exhibited systematic preference reversals choices bids. For matched expected value, systematically the higher-probability option but provided higher for offered greater amount win. This effect was accompanied by shift of attributes, fixating probabilities more amounts Our results suggest construction value risk depends task context partly because differentially directs attention at versus amounts. Since recent demonstrates neural correlates vary fixations, our also testable hypotheses regarding how modulates computation generate reversals.
