Accuracy-Contingent Analysis. Best fitting model (Experiment 2).

Effect Estimate S.E. z-value p-value
Intercept -1.20 0.25 -4.79 <.00001 *
Accuracy on Prev. Inst. (Incorr. vs. Corr.) 1.16 0.30 3.90 .00001 *

Note: Results of multi-level logit model with crossed intercepts for both Participants and Items. The lmer function in R was used [syntax: Accuracy ~ 1 + PreviousAccuracy + (1 | Participant) + (1 | Item)]. Model was a better fit than a model with fixed effects (χ2(1) = 15.15, p < .001). Models adding fixed effect of Condition or Condition × PreviousAccuracy interaction did not reliably improve fit. Adding random slopes to null model did not improve fit.
