Magnitude of the contour adaptation effect for different adapting and test spatial frequencies. (A) Data from observer SH for adapting SFs of 0.56, 1.1, and 2.14 c/deg. Error bars indicate 95% CIs based on 5000 bootstrap re-samples. (B) Individual subject data (filled symbols) and group mean data (open symbols, N = 5) adapting to 1.1 c/deg and testing with SFs between 0.4 and 3 c/deg. Error bars indicate SEM across observers; 0 on the y-axis indicates the point of veridical equality.
