Fig. 4.

Reaction times (RTs) for (a + b) Experiment 2a, (c + d) Experiment 2b and (e + f) Experiment 2c. The top panels (a, c, e) show RTs across multiple Training repetitions for High PE (brown, solid) and Low PE (blue, dotted) conditions. The bottom panels (b, d, f) show RTs for final Training and critical Study trials, which were intermixed (i.e., the x-axis implies temporal order only for single scene, but not across different scenes). Baseline condition (red, dashed). Error bars are standard errors. Final Training in the bottom panel is also Training trial 6 in top panel.
