Dual-process models of recognition posit that recollection and familiarity are subserved by two separate neuroanatomical systems: the hippocampus and the perirhinal cortex. Some researchers however, argue against this neuroanatomical distinction and suggest that recollection and familiarity reflect high- and low-strength memories processed similarly by an integrated system in the medial temporal lobe (MTL). We are currently using an fMRI event-related paradigm to investigate the mnemonic processing of words and non-words to determine whether recollection and familiarity are processed by separate systems in the MTL.
