Robust function of Cartesian coordinates in serial bias in 2D continuous spatial perception (experiments 2–4) (A) Experiment 2 (online experiment, short block, keyboard response). (Left) Participants maintained their fixation on the central point and were presented with a red dot at random locations in a 2D continuous space, followed by a square mask. During the reproduction stage, subjects adjusted the position of the red dot with keyboards to match the red dot position during the perception stage. (Middle and right) model comparison results for experiment 2, with the same setting as Figure 1IJ. (B) Experiment 3 (online experiment, short block, keyboard response). Left: Subjects performed the same task as experiment 2 but with a round-shape mask. (Middle and right) Model comparison results for experiment 3, with the same setting as Figure 1IJ. (C) Experiment 4 (offline experiment, long blocks, mouse response). (Left) Subjects performed the same task as experiment 2, but by using a mouse. (Middle and right) Model comparison results for experiment 4, with the same setting as Figure 1IJ.
