related hippocampal activity co-varies with amount of retrieved contextual information. The data are shown for test items endorsed as familiar (K) or recollected (R), further segregated by the confidence and accuracy of a subsequent source memory judgment made on recollected items. R-high and R-mod refer to accurate source judgments
made with high and moderate levels of confidence respectively. R-weak refers to source judgments made with low confidence or that were inaccurate.
