Understanding speech processing in children who stutter

Neural Processing of Speech Signals in Children Who Stutter

NA · University of Pittsburgh · NCT05668923

This study looks at how children's brains process speech to see if there are differences between kids who stutter and those who don't.

What this trial studies

This research aims to explore how speech and language are processed in the brains of children, particularly focusing on differences between those who stutter and those who do not. The study employs a combination of behavioral speech and language tests, electroencephalography (EEG), and functional magnetic resonance imaging (fMRI) to evaluate neural processes involved in speech sound encoding. Participants will undergo various speech-sound tasks while their brain activity is monitored, allowing researchers to quantify neural activations related to speech processing. The findings may provide insights into the underlying mechanisms of stuttering and inform future interventions.

Who should consider this trial

Good fit: Ideal candidates include children who are fluent English speakers, aged within the typical range of cognitive and language abilities, and either have developmental stuttering or are typically fluent without a family history of stuttering.

Not a fit: Patients with other communication disorders, cognitive impairments, or those taking medications that alter neural function may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and treatment options for children who stutter.

How similar studies have performed: Other studies have shown promise in using neuroimaging techniques to understand speech processing, but this specific approach focusing on stuttering is relatively novel.
