TTC distribution in the two-ball experiment (a) Estimated TTC variability versus ideal TTCs for each subject in the first ball experiment of the two-ball experiment. The red bars show the average of estimated TTCs for all subjects in each condition ± SEM. The outlier points (deviated more than two times the standard deviation from the mean value) are not considered. (b) Same as (a), for the second ball of the two-ball experiment. (c) Estimated TTC variability divided by σ2α, versus ideal TTCs for each subject in the first ball experiment of the two-ball experiment. (d) Same as (c), for the second ball of the two-ball experiment. In (a–d) the format is the same as Fig. 2b. (Number of dots = conditions × participants = 9 × 18 for the first ball, outliers = 10, Number of dots = conditions × participants = 8 × 18 for the second ball, outliers = 8) (e) Number of conditions × subjects in which each of the five probability distributions provided the best fit according to the AIC criterion for the first ball in the two-ball condition. (f) the same plot as (e) for the second ball in the two-ball condition.
