Abstract

In her interesting commentary, Valerie Gray Hardcastle argues that a P300 can be obtained even with "completely" novel stimuli which do not access or index LTM codes (1995). My argument is that, in order to get recognized, even a novel stimulus requires some sort of LTM information. Thus, even in this case some sort of "indexing of a memory code" would be necessary. I agree that the P300 reflects much more than just this type of process. However, this should be expected if the P300 reflects processes of a complex Working Memory System as I have proposed.
