    Abstract

    In our earlier article, we proposed that recent episodic experiences in patients with semantic dementia support the production of nongeneralisable, autobiographically constrained, "semantic-like" facts (Graham, Lambon Ralph, &, Hodges, 1997). We argued that this type of "semantic-like" knowledge was distinguishable from true semantic information because our two patients with semantic dementia showed no facilitatory effect of recent autobiographical experiences on their knowledge of golf and bowls; information which was presumably learnt prior to the onset of their disease. In this paper, we discuss the implications of these results for current views relating to the nature and organisation of long-term memory. © 1999 Psychology Press Ltd.
