Figure. Effortless Learning, Delayed Retrieval, and Retention Performance by Group.

Figure

Colored bars represent the mean number of errors in the (A) incidental recall, (B) delayed recall, and (C) recognition conditions of the Three Words Three Shapes test for the 3 diagnostic groups. Brackets indicate significant pairwise differences. Error bars indicate 1 SD; error bars are absent for groups that had perfect (ie, error-free) performances. AD indicates autopsy diagnosis of Alzheimer disease neuropathology; AMN, clinical diagnosis of amnestic dementia; FTLD, autopsy diagnosis of frontotemporal lobar degeneration; PPA, clinical diagnosis of primary progressive aphasia.

a Significant difference across the 3 groups (P = .001).

b Significant within-group difference (P < .025).
