PURPOSE: The purpose of this study was to evaluate if previously reported questionnaire-based differences in self-regulatory behaviors (Eggers, De Nil, & Van den Bergh, 2009, 2010) between children who stutter (CWS) and children who do not stutter (CWNS) would also be reflected in their underlying attentional networks. METHOD: Participants consisted of 41 CWS (mean age = 6;09 years) and 41 CWNS (mean age = 6;09 years) ranging from 4;00 to 9;00 years of age. Participants were matched on age and gender. The efficiency of the attentional networks was assessed by using the computerized Attention Network Test (Fan, McCandliss, Sommer, Raz, & Posner, 2002). RESULTS: Primary results indicated that CWS had a significantly lower efficiency of the orienting network compared to CWNS, whereas no differences were found on the alerting or executive control network. CONCLUSIONS: Current findings corroborate previously found differences in self-regulatory behavior and were taken to suggest a possible role for attentional processes in developmental stuttering.
