Top panel: Demonstration of how the point of subjective equivalence (PSE) was calculated with psychometric functions for an example participant, with stimuli congruent and incongruent with moving fingers. The PSE describes the point where participants judge the target and reference events to have equal duration. Judgment precision was inferred from the standard deviation of the Gaussian distribution that best fits the data; it pertains to the inverse of the slope, and lower thresholds reflect more consistent categorizations, thereby indicating better performance. Other panels: Mean PSEs for stimuli congruent and incongruent with moving fingers, for all experiments and perspectives. 1PP = first-person perspective; 3PP = third-person perspective. Error bars represent the standard error of the mean.
