Abstract

<p>The present study investigated the relationship between working memory capacity (WMC) and shadowing latency in 21 people who stutter (PWS) and 15 people who do not stutter (PWNS). WMC was measured using the Reading Span Test (RST). The mean RST score of the PWS group was significantly lower than that of the PWNS group. The PWS group also showed significantly shorter shadowing latency than the PWNS group. In terms of the relationship between WMC and shadowing latency, the PWS group had a significant positive correlation, whereas the PWNS group showed a significant negative correlation. These results suggest that PWS and PWNS employ different processing strategies in verbal working memory and shadowing tasks.</p>
