The aim of the present study is to investigate short-term memory and working
memory deficits in aphasics in relation to the severity of their language
impairment. Fifty-eight aphasic patients participated in this study. Based on
language assessment, an aphasia score was calculated for each patient. Memory was
assessed in two modalities, verbal and spatial. Mean scores for all memory tasks
were lower than normal. Aphasia score was significantly correlated with
performance on all memory tasks. Correlation coefficients for short-term memory
and working memory were approximately of the same magnitude. According to our
findings, severity of aphasia is related with both verbal and spatial memory
deficits. Moreover, while aphasia score correlated with lower scores in both
short-term memory and working memory tasks, the lack of substantial difference
between corresponding correlation coefficients suggests a possible primary
deficit in information retention rather than impairment in working memory.
