This study was to analyze the response properties of normal hearing young female adults (N = 29) in response to complex auditory digit expansions requiring both forward and backward working memory processes. The stimulus sets consisting of middle, front, and back digit combinations were digitally synthesized in the sequential length patterns of 3, 6, and 9 Korean and English digits. Individual digit spans had male and female voice options. They were randomly presented through the closed acoustic system and the corresponding performances were analyzed with special references to a speaker’s language and gender. The results were as follows: First, statistically significant differences were noted in Korean and English versions of complex digit sequences of the length six (p < .01). Second, there were no statistically significant preferences in the gender of the speaker in 3, 6, 9 length sessions of the complex digit patterns (p > .01). Third, the average values of the 50% performance index point were reduced in the order of complex digit span, backward digit span, and forward digit span. In summary, the data showed quantitative measures of the working memory consumptions and language dependency in complex digit sequences. Results can be used as initial reference data for the complex auditory digit expansion studies. This complex digit sequence procedure may also be clinically applied for screening memory-related disorders and impaired cognitive functions.
