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.
