Fig. 9.

Mean bias in the With Object condition, which contained a moving object (A), the absolute value of the heading error in the No Object condition, which did not contain a moving object (B), and mean variability in heading judgments in the No Object condition (C) are plotted as a function of trial duration from Experiment 3. Note that whereas A depicts heading bias, B depicts heading error. Positive bias indicates a heading error in the direction of the object's FoE, and a negative bias indicates a heading error in the direction away from the object's FoE. The absolute values in B correspond to errors to either side of the heading direction. Error bars indicate ±SE. The mean standard deviation (i.e., variability) across subjects is plotted in C.
