List 1 recall on interpolated tests (A) and in list 2 (B). The interpolated task labels on the X-axis of each panel indicate what happened with A–B pairs in the interpolated phase before participants learned A–C pairs in list 2. The interpolated tasks comprised cued recall tests of B responses without feedback (A–B test, no feedback) or with feedback (A–B test, feedback), and restudy of complete A–B pairs (A–B restudy). The item type coloring indicates whether pairs appeared in an A–B, A–C condition that included the same cues (A) in each list and different responses in list 1 (B) and list 2 (C) or in an A–B, — condition that included list 1 A–B pairs that did not correspond to any list 2 pairs. The colored points are marginal means estimated from mixed-effect models, and error bars are the corresponding 95% confidence intervals. The gray points are individual participant probabilities.
