Figure 2.

Behavioral results from Experiment 1. Videos that were recalled on days 1, 8, and 18 (Set 1) were recalled best, with only 4.5% of the details forgotten between day 1 and day 8 and a 2% improvement in recall on day 18. Videos that were recalled on day 1 and day 18 (Set 2) were also remembered reasonably well, with only 14.7% of the details forgotten by day 18. By contrast, videos that were not recalled on day 1 but were first recalled on day 8 (Set 3) showed substantial forgetting, with the number of details recalled being 47.8% lower than the level of recall on day 1 on Sets 1 and 2. Performance on Set 3 improved by 7.6% between day 8 and day 18. Error bars indicate SEM.
