Fig. 2. Information sampling behaviour on Attribute and Option trials reveals preference for sampling current best alternatiive.
(A) On attribute trials where a third cue was sampled, the probability of third saccade being directed diagonally back towards option 1, rather than vertically to remain on option 2, is high when Cue 1 is high value and Cue 2 is low value. (B) On option trials, the number of cues sampled is lowest when Cues 1 and 2 are high value, but surprisingly it is highest when Cues 1 and 2 are low value, even though this provides complete information about which option to choose.
