Performance on the International Shopping List (ISLT) Delayed Recall Task, by participants who either failed the scopolamine challenge test (SCT) at baseline (N = 28, at end of study) vs. those who passed the SCT at baseline (N = 30, at end of study), modeled over all four study visits. Dark lines indicate group mean scores at each visit, with SE bars provided. Both between- and within-subject variation is represented in each group, by displaying individual subject change over time, with each case yoked to the group baseline mean score
