\n[\/vc_column_text][vc_empty_space][vc_column_text css=””]Introduction<\/strong>: Behavioral and questionnaire-based studies suggest that children who stutter (CWS) exhibit poorer response inhibition than children who do not stutter (CWNS). However, the behavioral findings in adults who stutter (AWS) are less unequivocal and mainly based on manual response inhibition. Further study is therefore needed, especially given the lack of studies on verbal response inhibition among these groups.<\/span><\/p>\n

Methods<\/strong>: Thirteen AWS and 14 adults who do not stutter (AWNS) participated in a verbal stop signal task (SST) in which they were asked to read aloud six Chinese characters as fast as possible during the go-signal and ignore-signal trials and refrain from naming them during the stop-signal trials.<\/span><\/p>\n

Results<\/strong>: The two groups showed a comparable response reaction time in the go-signal and ignore -signal trial conditions. Furthermore, there were no significant differences in terms of the stop -signal reaction time (SSRT) and accuracy. However, a significant positive correlation was found between SSRT and the frequency of stuttering in conversation but not in reading.<\/span><\/p>\n

Conclusion<\/strong>: Current findings seem to provide additional support that exogenously triggered response inhibition among AWS does not differ from AWNS. The association between stuttering frequency and SSRT seems to suggest that individuals with more severe stuttering in conversa-tional speech have reduced exogenous response inhibition. However, this finding needs to be further explored in future studies using different measures of stuttering severity.<\/span>[\/vc_column_text][vc_empty_space][vc_btn title=”Download” css=”” link=”url:http%3A%2F%2Fdoi.org%2F10.1016%2Fj.jfludis.2022.105957|title:About%20us|target:_blank|”][vc_column_text css=”” el_class=”prevnext”]
