Understanding speech prediction and errors in people who stutter

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates how individuals who stutter process auditory information and how this affects their speech. Participants will engage in various tasks, such as naming pictures and reading aloud, while their speech and brain activity are monitored. The study aims to explore the role of auditory feedback and brain stimulation in speech production, providing insights that could lead to new interventions for stuttering. By analyzing the neural and behavioral responses, researchers hope to establish a foundation for future therapies.

* not taking any medications that affect the central nervous system
* absence of safety contra-indication for tDCS, TMS and MRI (for adults)
