Impairments of auditory-verbal short-term memory: Do selective deficits of the input phonological buffer exist?

摘要

The existence of the functional syndrome of auditory-verbal short-term storage impairment was used as strong supporting evidence for the presence of a phonological buffer in the first version of the Baddeley-Hitch working memory model. In later versions the syndrome corresponded to the selective impairment of the phonological input buffer. The present paper considers whether the correspondence between the functional syndrome, represented by 20 published cases, and a Baddeley-Hitch model component is still of value to memory theory. The following potential problems for the theoretical utility of the correspondence are considered:
