Fig 3. Shapes found in an exploitation phase are perceived as similar.

Participants who did not play the creative foraging game chose the odd-one-out among four shapes, three from the same exploitation phase and one from a different exploitation phase found by the same player. Participants chose the outlier twice as often as by chance. Means and std (computed using bootstrapping) are shown (p<0.0001, see Section D in S1 File).
