Figure 3. Results from Experiment 2.

All data is presented analogously to Figure 2 (Experiment 1). A Raw data and psychometric function fits for one author (circles, solid line) and one naïve participant (squares, dashed line) from Experiment 2A. The inset shows the changes to the stimulus (hard apertures for the distractors and lower background luminance). All other aspects of the stimuli and task were identical to Experiment 1. B PSEs (and confidence intervals) for all three participants in Experiment 2A. The rightmost bar shows the mean mislocalization effect for the group (and standard error). The stimulus manipulations abolished the motion-induced mislocalization effect. C Raw data and psychometric function fits from the crowding experiment (Experiment 2B). There is no clear separation of psychometric functions between inward and outward drifting distractors. D 75% correct thresholds (with confidence intervals) for all participants and group means (with standard errors). There was no significant difference in crowding for distractors of opposing motion directions.
