| Research Abstract |
The purpose of this study was to investigate language processing abilities among adults who stutter by event-related brain potentials(ERP). Subjects were 15 adults who stutter (AWS) (11 males and 4 females) and 15 adults who do not stutter (AWNS) (9 males and 6 females). The event related potential (ERP) effects of language processing were compared for the two groups. AWS and AWNS showed following substantial differences in P600 and N400, even though the two groups did not differ in the accuracy of sentence judgment observed in the button press task; 1) AWS exhibited decreased amplitude of N400. 2) AWS exhibited increased amplitude of P600. This study, therefore, revealed language processing differences between AWS and AWNS, even when no speech production was required.
