Abstract:
|
The present study was designed to test the vicious cycle hypothesis, which posits that stuttering is caused by overmonitoring the preverbal speech plan. We measured three electrophysiological neural markers elicited by errors: the error-related negativity (ERN), the error positivity (Pe), and alpha suppression. The ERN was heightened in stutterers and the Pe was heightened in severe stutterers, but we deem it unlikely that hyperactive self-monitoring is the only cause of stuttering. Additionally, the present study provides evidence that preverbal speech monitoring may utilize the same neural mechanisms as action-monitoring. |
