Episodic and semantic memory tasks performed inside the scanner. A, Episodic memory: Participants completed 72 trials of the episodic task. In each trial, participants first saw a cue telling them which clip to recall. They then closed their eyes for 6 s and recollected the clip as vividly as possible. Once the 6 s had elapsed, they heard a tone signaling them to open their eyes. They then rated the vividness of the recollection as well as stating in which of the three modalities the clip had originally been presented. They then had a 4 s fixation pause before the next trial commenced. B, Semantic memory. Participants completed 72 trials of the semantic task. Each trial started with a cue denoting the word to which they were to associate words. They then closed their eyes for 6 s and thought of as many words associated with the cue as possible. Once the 6 s had elapsed, they heard a tone signaling them to open their eyes and to rate how related the words they thought of were to the cue word, as well as the number of words that they came up with in the 6 s (1 meaning none, 2 up to three words, and 3 >3 words). They then had a 4 s fixation pause before the next trial commenced.
