요약Purpose:Previous literature has found that children who stutter (CWS) exhibit differences in executive function skills, including inhibitory control, compared to children who do not stutter (CWNS). The current study aimed to determine the similarities and differences between behavioral and neural indices of inhibitory control in both groups of children.Method:Forty CWS and 36 CWNS, ages 3 to 8 years, completed two inhibition tasks. Twenty CWS and 16 CWNS completed an inhibition task, a Go/No-Go task, while electroencephalography (EEG) was collected to evaluate neural processes underlying inhibitory control. Children also completed Head-Toes-Knees-Shoulders (HTKS), a measure of behavioral self-regulation that assesses inhibitory control and other cognitive processes.Results:CWS and CWNS performed with similar behavioral accuracy and response times on the inhibitory control tasks (HTKS and Go/No-Go). HTKS accuracy and P2 mean amplitudes elicited by the No-Go condition were found to be significantly correlated for CWS. HTKS accuracy was found to be correlated with P3 mean amplitudes elicited by the Go condition across participants, with the strongest relationship for CWNS. All other correlations were not found to be significant.Conclusions:These findings suggest that CWS and CWNS perform similarly on tasks involving inhibitory control. In CWS, increased attentional engagement, which is needed to withhold a response during the No-Go condition of the Go/No-Go task, indicated by larger P2 responses, may support stronger performance on HTKS, especially on the complex rule-changing section. Additionally, when children, across both groups, are able to use their attention more efficiently during tasks with more familiarity, as with the Go condition in the Go/No-Go task, they perform better on all parts of the inhibitory control task (HTKS). Together, these preliminary findings suggest that relationships between behavioral responses and neural processes that regulate inhibition may differ in subtle ways between CWS and CWNS. Replication of this study with a larger sample size is needed to confirm the findings of this study.
