Figure 1.

Schematic representation of the study design. At the initial assessment, from each participant, we obtained a corpus of 9 event memories (Events 1-9). Participants were tested for recall of 3 unique events after each of the delay intervals of 1 year, 2 years, and 3 years. For each individual participant, random assignment was used to determine the delay interval over which a given event would be tested. The figure depicts an example random assignment of Events 1-9 to each of the 1-, 2-, and 3-year delay intervals.
