Fig. 6: Reference-adjacent events also contribute to the temporal asymmetry (main experiment).

A Illustration of the annotation approach. We extended the annotation procedure depicted in Fig. 5A to also label unreferenced events that were either temporally adjacent to (i.e., immediately preceding or proceeding) a referenced event (reference-adjacent events) or not (remaining events). B Adjacent reference rate for unreferenced events as a function of lag. Across all possible just-watched segments (lag 0), the bar heights denote the average proportion of unreferenced events in other past or future segments that were temporally adjacent to any referenced event. C Difference in hit rates between unreferenced events and remaining events. To highlight the effect of reference adjacency on retrodiction and prediction of unreferenced events, here we display the difference in across-segment mean hit rates between unreferenced events and remaining events, as a function of temporal distance (lag) to the just-watched segment. D Hit rates for remaining events. Participants (n = 36) across-segment mean response hit rates for unreferenced events that were not temporally adjacent to any referenced events are displayed as a function of temporal distance to the just-watched segment. Each point represents one segment (paired with a just-watched segment). Panels (B–D): colors are described in the Fig. 4 caption. E Hit rates and counts of referenced, reference-adjacent, and remaining events. As a function of temporal distance to the just-watched segment, the sub-panels display the numbers (x-axes) and proportions (y-axes) of referenced (red), reference-adjacent (purple), and remaining (gray) events that participants hit (darker shading) or missed (lighter shading) in their uncued retrodictions (top sub-panel) and uncued predictions (bottom sub-panel).
