ABSTRACT |
Backward digit span was frequently adopted as a useful tool for evaluating auditory working memory and 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 adults with 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 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 6 in 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 spans can contribute to exploring auditory memory functions and the related clinical
implications. |
