Impairment of verbal short-term memory following left temporoparietal and upper parietal lesions

Abstract

    In order to investigate differences between two cases of verbal long-term and short-term memory impairments following left temporoparietal and left upper parietal lesions, short-term memory tasks were carried out according to two conditions, i. E. auditory presentation and visual presentation. Results showed no differences between these conditions in the temporoparietal lesion patient, but in the upper parietal lesion patient results significantly declined under visual presentation. This disparity between patients may indicate separate mechanisms. These results partly agreed with Soma's schema of the phonological loop of working memory (Soma 1997).
