My research is focused on understanding the functional and neural basis of two dimensions of memory functioning that lie at the opposite ends of the awareness spectrum. The first is implicit memory, or alterations in behavior that are not dependent on explicit awareness of a prior processing event. The second is metamemory: specifically, what is the basis for self-reflective evaluations of memory performance and how do these evaluations guide efforts at memory retrieval. The basic approach I have employed within each of these areas is to test well founded cognitive theories using several complimentary research methodologies including, (a) task dissociations in neurologically damaged patients and healthy controls, (b) human electro and magneto encephalograhic recordings (EEG and MEG), (c) functional Magnetic Resonance Imaging (fMRI), and (d) the multimodal integration of fMRI and MEG.
