These curves were constructed by analysing response proportions at precise intervals of 0.1 degrees, showing a preference for the comparison circle being larger than the target circle. The logistic function was employed to quantify the probability (P) of perceiving the comparison circle as larger than the target circle. The color coding in the figure represents the different conditions: small inducer – simultaneous viewing (solid red line), large inducer – simultaneous viewing (solid green line), small inducer – delayed viewing (dashed red line), and large inducer – delayed viewing (dashed green line).
