(A) Subject reported mean tilt perception vs. radius grouped by view condition. Actual tilt angle was 10 degrees in all cases (B) Correctness (fraction of times subjects were within +/− 2 degrees) and confidence for “conflict - C” (viewing and actual radius different), “no conflict - NC” (viewing and actual radius the same), and “dark - D” cases. Significant results (p < 0.05) are marked *. Correctness and confidence would be equal if subjects were able to perfectly judge their ability to perform the estimation task. Error bars represent standard error.
