Proportion of “later than beep” responses as a function of TTPt (A), TTPf (B) and fDist (C) for each level of occlusion (red = 10% occlusion; green = 30% occlusion; blue = 50% occlusion). Different PSS are obtained for TTPf and fDist due to the different range of values of the variables (see Method section and Table in S1 Table), and therefore are not due to an effect of occlusion on judgment.
