The term semantic memory refers to neurocognitive systems for the storage and processing of information about the world. We have published a number of research articles on this topic over the last 20 years.
Recently, we have published a chapter explaining in detail a new theory of information processing modularity, with examples from semantic memory studies, including a new method that enables researchers to use event-related brain potentials (ERPs) to isolate and distinguish among modular and interactive processors in the brain.

Hart & M.A. Kraut (Eds.), Neural basis of semantic memory. Cambridge, U.K.: Cambridge University Press.
Much of our previous research on semantic memory is reviewed in a Psychonomic Bulletin & Review article which can be dowloaded by clicking here.
