Figure 5. Probability vs. area choices in Experiment 1.

Equivalent radius in the probability choice task (A) and in the area choice task (B) are plotted against the true area equivalent radius. Each dot is for one subject and one rectangle condition. Green denotes subjects of the Gaussian type. Gray denotes the area-matching type. Note that the probability choices of the area-matching type improperly agreed with the predictions of area-matching, while the area choices of the Gaussian type improperly deviated from the true area equivalent radii.
