Dysphasic memory impairments are seen, for example, in the difficulty of retrieving the spoken form of a word, given some specification of its meaning or in retrieving a meaning, given the spoken form in recovering the orthographic (written) form of a word, given its spoken form and so on.l Let us call the ability that is needed for such tasks and which is evidently disturbed in dysphasic impairments 'language memory', to distinguish it both from the more general (non-episodic and non-linguistic) knowledge of the world-and from memory for particular, experienced (non-linguistic) events or episodes, both of which may be well preserved in many forms of dysphasia (Allport, 1983a). Of course, this is not to say that they are, primarily, impairments of 'episodic' memory, that is, of memory for particular experiences or events but they are impairments, nonetheless, of memory, or memory-retrieval, for the previously familiar patterns of language.
Allport Distributed memory, modular subsystems and dysphasia INTRODUCTION I take it as self-evident that the dysphasias-acquired disorders of language-are a class of memory disorder.
