Figure 4. Last gaze properties.

(a) Probability to choose the symbol with a higher Q-value split by the last gaze location (higher or lower Q-value symbol) and model-based/model-free groups. Model-based subjects tend to choose the last seen symbol irrespective of the Q-value difference. Bins with fewer than five subjects per group were excluded from the plots. Q-value differences were normalized to 1 on the group level. Bars denote s.e., clustered by subject. (b) Effect of gaze time advantage on probability to choose the last seen symbol. Model-free subjects are more likely to choose the last seen symbol if they spent more time looking at it during the trial.
