Predictions of the pure association variant of the Context Maintenance and Retrieval (CMR) model, which assumes that a change in task information does not disrupt temporal context or cause an event boundary. A. In control lists, encoding-retrieval similarity (ERS) between the temporal context state of a recalled item and the temporal contexts of its neighbors during study. Lag refers to the distance in serial position between two items from study (see Figure 1E). Like CMR, the pure association variant predicts that temporal context states will be more similar between the recalled item and neighboring items from study. B. Unlike CMR, the pure association variant predicts that neural similarity is identical for two neighboring items within the same event or two items across different events. C. The pure association model variant predicts that the recall of an item bordering an event boundary leads to retrieval of that item’s temporal context states from study. Because these temporal context states do not incorporate disruptions, ERS values are nearly identical between items studied with the same task versus items studied with different tasks. D. The pure association variant predicts that, when compared to control lists (gray circles), transitions in two-task lists are enhanced for items recalled within the same event (darker teal lines). By contrast, recall transitions across events (lighter orange lines) are equivalent to control lists. Both of these predictions are present for preboundary items (squares) and boundary items (triangles). E. In the experimental data (replotted from Figures 2B, 5C,D), participants exhibit reduced recall transitions in two-task lists to items from different events (lighter orange lines), whether transitioning from preboundary items (squares) or boundary items (triangles). By contrast, participants exhibit similar or greater transitions for items recalled within the same event (darker teal lines). F. The full CMR model makes both critical predictions of reduced transitions for items from different events and enhanced transitions between items of the same event. For more distant items with darker teal lines, items may be from the following event. Error bars represent Loftus and Masson (1994) 95% confidence intervals. Assoc. = Association. Sim. = Similarity.
