Figure 3: One-year recall.
From: Sleep Supports the Slow Abstraction of Gist from Visual Perceptual Memories
In a two-alternative forced-choice task, above-chance performance was only observed for prototypes when subjects had slept after encoding ($$$p < 0.001), but not in the Wake condition or for recall of old shapes (item memory). Importantly, subjects showed significantly better memory for prototypes (gist memory) when they had slept after encoding compared to the other three conditions (***p < 0.001). Mean and SEM are shown. N = 17.
