    "subtitle": null,
    "abstract": "When making decisions, we are often forced to choose\nbetween something safe we have chosen before, and\nsomething unknown to us that is inherently risky, but may\nprovide a better long-term outcome. This problem is known as\nthe Exploitation-Exploration (EE) Trade-Off. Most previous\nstudies on the EE Trade-Off have relied on response data,\nleading to some ambiguity over whether uncertainty leads to\ntrue exploratory behavior, or whether the pattern of\nresponding simply reflects a simpler ratio choice rule (such as\nthe Generalized Matching Law (Baum, 1974; Herrnstein,\n1961)). Here, we argue that the study of this issue can be\nenriched by measuring changes in attention (via eye-gaze),\nwith the potential to disambiguate these two accounts. We\nfind that when moving from certainty into uncertainty, the\noverall level of attention to stimuli in the task increases; a\nfinding we argue is outside of the scope of ratio choice rules.",
