We discuss the role of short-term auditory verbal storage
within a working memory system. Data from single case studies of
patients with left parietal lesions and selective impairment of memory
span are discussed in order to address the question of the functions
of short-term memory in language processing. The backup resource of
auditory verbal short-term memory is required for those tasks that
necessitate backtracking in order to integrate a verbal message within
a developing central cognitive representation.
