Neural Processing of Speech Signals in Children Who Stutter

What this Trial Is About

Researchers are investigating how speech and language are processed in the brains of children, focusing on differences between those who stutter and those who do not. This study aims to improve understanding of the neural mechanisms behind speech sound encoding and how these processes change with different task demands, using advanced brain imaging and computational modeling methods. Participants will undergo a range of speech sound tests, EEG tasks measuring brain responses to speech signals, and functional MRI scans to explore brain activity during speech tasks. These assessments include listening and identifying syllables, as well as comprehending continuous speech, both in quiet and noisy settings. The study also involves structural brain scans and uses computational techniques to analyze brain activity and speech processing. Children in the study will complete standardized speech, language, and cognitive tests administered by trained professionals. They will wear scalp electrodes for EEG recording and undergo MRI scanning with safety screenings for metal objects. Researchers will measure multiple brain responses and activations related to speech processing during single sessions lasting up to two hours. The entire participation involves behavioral assessments, brain recordings, and imaging to examine speech sound identification and neural activity.
