Experiment 3: Catch-trials in the same-physical-size condition. The graph compares the average judged locations in the catch trials with those from the test trials at the same target distance and eye level. Distances are underestimated with both the test and catch targets. Furthermore, catch and test targets with the same angular size are perceived at the same distance despite the difference in their physical distances (and physical sizes), with targets having the smaller angular size being perceived as farther. This reveals the effect of angular size on perceived distance.
