Abstract

Purpose: 
According to several studies, people with childhood onset fluency disorder show differences in executive functions compared with normal peers. The purpose of this study was assessment of 7-12 years old children with childhood onset fluency disorder and in four areas of executive functions including sustained attention, Auditory working memory, reaction time and response control.
Methods: 
This research was a comparative study. Twenty children with childhood onset fluency disorder and 20 normal children were selected through Speech Therapy Centers and schools in Tehran. They were tested by auditory (N BACK) to measure auditory working memory, continuous performance test (CPT) to evaluate sustained attention and reaction time and the go / no go test to measure response control. Also, the severity of non-fluency was measured by using the percent syllables stuttered. The results were analyzed by independent T-test and Walsh test.
Results: 
The results showed the significant differences between children with childhood onset fluency disorder and normal peers in the areas of ​​sustained attention (p=0.019), auditory working memory (p=0.038) and response control (p=0.033). However, no difference was observed between the scores of children with childhood onset fluency disorder and normal children in the area of ​​reaction time (p= 0.329) (p>0.05)
Conclusion: 
The results showed that children with childhood onset fluency disorder are weaker in three areas of executive functions such as sustained attention, auditory working memory, and response control in comparison with their normal peers.
