Anchor point eye movement analyses for the size (left) and contrast (right) single-dimension tasks. Data points represent the preference ratio ([number preferred −number nonpreferred]/[number preferred + number nonpreferred]) for each participant. Biases toward the taller bar and darker bar are plotted to the left, and biases toward the shorter and lighter bar are plotted toward the right. Gray dashed lines represent the threshold value (0.4) for having a bias toward a specific feature
