Experiment 2 predictions.
Predictions for normal and catch trials in Experiment 2 for a trial in which the object moves from right to left. (A) and (B) depict the optic flow field on normal trials and catch trials, respectively. Gray vectors depict the optic flow of the stationary background and yellow vectors depict the optic flow of the moving objects. (C) and (D) show the object-motion component (dotted lines) and how it is recovered by subtracting the self-motion component (faded dash lines) from the optic flow of the moving objects.
