The working memory characteristics of aphasia patients were explored in different tasks and test materials in the
current study. 20 aphasia patients (aphasia group, 35-56 years old) and 20 normal cases (control group, 35-56
years old) were asked to finish auditory repetition and auditory recognition tasks of numbers, notional and function
words. The maximum length of the string correctly completed was referred to as the working memory span. The
working memory span was compared between the two experimental groups. Results showed that the working
memory span of aphasic patients was significantly lower than that of control group. Numbers were the easiest for
aphasics. In different tasks, the difficulties from high to low were as follows: positive sequence repetition, reverse
sequence repetition, positive sequence recognition and reverse sequence recognition.
