    "title": "Individual Differences in Gaze Dynamics in Risky Decision-making",
    "subtitle": null,
    "abstract": "In risky decision-making, expected utility (EU) theory is\nwidely used to examine people's risk attitude and choice\nbehavior. However, it is unknown how risk attitude relates to\nattention and information search. In this paper, we explore the\nrelationship between risk attitude (as measured by a variant of\nEU) and eye movement patterns (which serve as a proxy for\nattention and information search). Participants made choices\nbetween gambles presented perceptually as flickering grids in\nwhich monetary values were indicated by colors and\nprobabilities by color proportions. To explore attention and\ninformation search patterns, we investigated eye movement\npatterns when faced with different gambles and correlated\nthese patterns with the parameters of EU. We observed that\npeople who are more risk-seeking (as determined by\nmodeling) tend to look at risky options more often. These\nresults bridge choice behaviors conceptualized by EU and\ninformation search strategies under risky decision-making\nrevealed by eye movements.",
