Extended Data Fig. 1

Data presented is similar to main Fig. 1, but only for participants in the behavior-only group, when separating trials into 5 levels of PE (PE0, small (<|3|) and large (>=|3|) PE+/PE-). a. Proportion of discrimination errors as a function of objective time difference between the two images (Δt), averaged across all trials separately for each PE-type. Shown is the main effect of Δt (F4,68 = 26.9, p <10−12, η2 = 0.61), but no difference between PE types (F4,68 = 0.7, p = 0.59). b. Proportion of discrimination errors as a function of PE-type and Trial-type. An interaction between PE-type and Trial-type is evident as PE+ and PE- bias performance in opposite directions relative to PE0 trials (F4,68 = 9.79, p < 10−5, η2 = 0.36). Inset: after correction for individual Time-Order Error (TOE). c. Proportion of discrimination errors as a function of time difference between images (Δt), separately for LS and SL trials. PE+ and PE- bias performance in opposite directions relative to PE0, for all values of Δt. Different outcome magnitudes are not significantly different (p>0.12), and no main effect of Trial-type (F1,17 = 4.1, p = 0.06). d. Proportion of discrimination errors as a function of time difference between images (Δt), separately for LS and SL trials and corrected for TOE. PE+ and PE- bias performance in opposite directions relative to PE0, for all values of Δt. e. Proportion of discrimination errors as a function of individual Just-Noticeable-Difference (JND), corrected for TOE, fitted to a logistic function after JND normalization. Error bars represent SEM (n=18).
