Fig. 1: Experimental design and memory performance.

a Experimental design. Subjects performed a continuous recognition task on a series of natural scene images. On each trial, subjects indicated whether the current image had been presented at any point, so far, in the experiment. Photos from the COCO image dataset/Flickr45. b Task schedule. Each subject completed 30–40 fMRI scan sessions. The first session corresponds to day 0. c Memory discriminability (d’) as a function of session number. Each colored line without error bars represents data from an individual subject. The blue line with error bars shows the mean d’ across subjects. Chance performance corresponds to a d’ of 0. The vertical gray dashed line marks the last session (30) included in the main analyses. d The cumulative number of hit trials as a function of session number. e The cumulative number of false alarm trials as a function of session number. Error bars denote the standard error.
