Summary

Story summary

Agit Simsek, a Turkish researcher, conducted an EEG study of 29 adults who stutter and 30 controls, all right-handed and aged 18-45.
The EEG showed delayed, weaker event-related potentials to 1000 Hz tones in stutterers, and greater severity linked to slower processing and higher anxiety.
Severe stutterers showed faster, stronger responses to unexpected 1200 Hz tones.
The study’s limitations included a modest sample, cross-sectional design, pure-tone stimuli, and no multiple-comparison correction.
