초록

Backward digit span was frequently adoptedas a useful tool for evaluatingauditory working memoryand learning. The detailed response data, however, were not available for backward Korean digit span sets. In this study, backward Korean monosyllable digit spans were examined in normal hearing young adultswith special reference to the previous forward Korean digit span data. 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 backward digit span responses were recorded and analyzed on the custom-made computerized workstation. In this result, no statistically significant differenceswere 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 6in this backward Korean digit span study. This led to about 2 index differences from the average values of forward and backward digit span data (p < .01). This discrepancy corresponded to the additional processing in the backward digit span task model. In conclusion, the data exhibited the similar trends as those from backward digit spans with other languages. These backward and forward digit spanscancontribute toexploring auditory memory functions and the related clinical implications.
