Overview of experimental design. While in the scanner, participants encoded emotionally negative and neutral images that were displayed in short blocks of 4 images. For each block, participants answered one of two encoding questions that were cued before the block, and the encoding question served as the source context for each image. One day later, participants completed a three-stage memory test for each studied item intermixed with new items, first rating whether the item was recollected (R), familiar (F), or new (N), then choosing the source context associated with the item, and finally rating confidence in the source decision.
