(a) Multiple regions exhibited shifts in event timing between initial and repeated viewings, with event transitions shifting earlier in time with subsequent viewings. Across the brain, anticipation timescales varied from a few seconds to 15 s, with the longest timescale anticipatory signals in prefrontal cortex and the temporal pole. Anticipation followed a posterior-to-anterior hierarchy, with progressively anterior areas generating anticipatory signals that reach further into the future (Spearman’s rho = 0.58, p=0.0030). Statistical thresholding was conducted via a permutation test, with correction for false discovery rate (FDR), q<0.05. (b) Event by time plots for three sample regions from (a), selected post hoc for illustration. Because the HMM produces a probability distribution across states at each timepoint, which can reflect a combination of current and upcoming event representations, we plot the expected value of the event assignments at each timepoint. The upward shift from the first viewing to subsequent viewings indexes the amount of anticipation.
