ABSTRACT
Bob Bjork’s overarching view of human learning and memory as dynamic and constructive capabilities adapted to constraints of the brain “wetware”—notably the view of forgetting as a dynamic consequence of memory updating captured by the title of this volume-will enduringly inuence our science. at view, which implies going beyond the functionalist computer metaphor (e.g., Richardson-Klavehn & Bjork, 2002), ts well with the view that contributions from neurobiology are essential to progressing cognitive theories (e.g., Buzsáki, 2006; Henson, 2005; Moscovitch, 2008; Richardson-Klavehn et al., 2009; Rugg, 2009). Here I hope to present some telling examples of such contributions from functional neuroimaging. I dene neuroimaging to encompass both hemodynamic (e.g., functional magnetic resonance imaging, fMRI) and electrophysiological methods (e.g., electroencephalography, EEG, and magnetoencepalography, MEG), given advances in the spatial resolution of the latter methods, and I also hope to illustrate the benets of relating these approaches. e chapter is organized into two main parts, the rst addressing research on encoding processes, extending interests that I developed while a graduate student working with Bob (Richardson-Klavehn & Bjork, 1988), and the second addressing research on retrieval processes-and in particular research on retrieval inhibition, a topic close to Bob’s heart (e.g., Bjork, 1989, 2007).
