This chapter provides an overview of functional magnetic resonance imaging (fMRI) studies of task switching. It addresses four questions. The first is whether neuroimaging evidence supports theories emerging from behavioral studies of task switching. The second question is whether neuroimaging evidence provides support for the often-implicit assumption that “task switching” represents a coherent area of study—that is, that common mechanisms or common organizational principles govern task switching regardless of the particular tasks involved. The third question is whether consistent dissociations are observed among different forms of task switching, for example switching between perceptual attributes versus switching between different sets of potential responses. The fourth, more exploratory, question is whether switching of “retrieval set” in long-term memory shares principles and mechanisms with task switching as more traditionally studied.

Keywords:   functional magnetic resonance imaging, fMRI, cognitive control, task switching, long-term memory
