Overview of experimental design. A, Participants first completed a baseline rest scan followed by a scene/face localizer task. Following the localizer task, participants completed 3 rounds of motivated encoding, incentivized retrieval on a subset of trials, and postencoding rest. Postencoding rest followed retrieval as to ensure that individuals were not incentivized to rehearse information. At a 24 h delay, participants completed a nonincentivized memory test for memoranda that was not tested during the immediate test. B, During motivated encoding, participants were trying to associate trial-unique pictures and words. Before encoding, a condition cue appeared indicating whether successful encoding would contribute to a high-value bonus ($20) or a low-value bonus ($1). High- and low-value encoding was intermixed across encoding blocks.
