Tilt aftereffect and orientation prior overview. (A) Example of the tilt aftereffect. Stare at the central red fixation dot of the top Gabor patch for 30 s, then shift your fixation to the fixation dot of the bottom Gabor patch. The bottom patch may appear to be tilted counterclockwise despite being vertical. This is the tilt aftereffect, which is a perceived repulsion away from the orientation of the adapting Gabor. (B) Stereotypical aftereffects observed as a function of the difference in orientation between the adaptor and test stimulus. Positive values indicate a repulsive effect, and negative values indicate attraction. (C) Typical distribution of orientations observed in naturalistic images, with a dominance of cardinal orientations over obliques. This dominance has led to our prior for orientation information, resulting in the oblique effect.
