ABSTRACT
Digit spans were frequently used as a potential tool for evaluating central auditory signal processing such as auditory memory and learning. The basic detailed data, however, were not available for Korean digit span sets. In this study, Korean monosyllable digit spans were examined in normal hearing adults. The stimuli were synthesized in 1 to 10 Korean digit spans of male and female voices. They were randomly presented through the closed acoustic system for 20 subjects (10 males and 10 females). The corresponding responses were recorded and analyzed on the custom-made computerized workstation. In this result, no statistically significant differences were observed in terms of the lateralization (left/right) and the gender of the subjects and speakers (p > .01). The average performance point of 50% was determined at the index value of about 8 in this Korean digit span study. In conclusion, the data exhibited the similar trends as those from digit span experiments with other languages. Further language specific outcomes can be analyzed with the addition of the related digit intervals and controlled acoustical features. This procedure may also contribute to clinical applications on screening and probing memory-related central processing disorders.
