Abstract
PURPOSE: The purpose of the present study was to examine relations between children's exogenously triggered response inhibition and stuttering. METHOD: Participants were 18 children who stutter (CWS; mean age = 9;01 years) and 18 children who not stutter (CWNS; mean age = 9;01 years). Participants were matched on age (±3 months) and gender. Response inhibition was assessed by a stop signal task (Verbruggen, Logan, & Stevens, 2008). RESULTS: Results suggest that CWS, compared to CWNS, perform comparable to CWNS in a task where response control is externally triggered. CONCLUSIONS: Our findings seem to indicate that previous questionnaire-based findings (Eggers, De Nil, & Van den Bergh, 2010) of a decreased efficiency of response inhibition cannot be generalized to all types of response inhibition.
