Summary of VTEs by session and block. (A) The left histogram shows the number of VTE trials per block, whereas the right shows the proportions of VTEs per block. The right histograms show no differences in how proportions of VTE per block are distributed for either place (green) or alternation (gold) blocks. (B) Within-session differences in VTE on correct compared to incorrect choices show that VTE was far more likely to lead to a correct choice. Raw numbers are shown on the left (using a log y-axis), and the distribution of within-session differences is on the right. (C) Although VTE was more likely to lead to correct choices, there were no differences in the probabilities of VTEs occurring early compared to late in blocks. Gold lines in B and C indicate instances in which a value on the right was higher than its paired value on the left.
