Disagreement exists in the literature over whether it is possible for new
semantic (factual) information to be learned in the absence of episodic
(event) memory. We report the case of R.S., a 49-year-old amnesic man, who
we found to have acquired information about famous people, public events
and new vocabulary during the 13-year period since he became amnesic,
despite having no measurable anterograde episodic memory function and a
profound loss of autobiographical memory. These data suggest that at least
some severe amnesics are able to acquire new semantic knowledge, provided
that critical temporal neocortical regions are spared. We discuss these
findings in the context of recent connectionist models of memory.
