FIGURE 4.

Performance during the Study Phase of Experiment 1B for high and low similarity categories (left panel). The right panel presents data from the second day refresher only presented in Figure 2 and is depicted here for comparison purposes. Solid lines indicate interleaved study, while dashed lines indicate blocked study. Error bars indicate standard errors of the means. Chance-level performance in this task was 0.33 and is represented in the graphs by the horizontal dashed line.
