We currently are recruiting children and adults who do and do not stutter for three research studies.

Neural bases of childhood stuttering

Funded by the National Institutes on Deafness and other Communication Disorders (NIDCD/NIH), we are conducting a 5-year, longitudinal investigation to examine brain developmental trajectories in children who do and do not stutter. We will be using both structural and functional neuroimaging techniques to assess brain development to examine whether there are sex-specific developmental patterns that lead to recovery versus persistence in developmental stuttering. 

Children who are between 3-6 years of age, have been stuttering for more than 6 months, and are monolingual speakers of English may qualify for the study. We are also recruiting typically developing children to serve in the comparison (control) group. These children must meet all criteria as listed above but should not have had a history of stuttering or other speech conditions.

We provide payment to parents for their time involved and transportation costs. In addition, the team provides, at no cost, a comprehensive report of your child’s speech, language, hearing, and IQ assessments. You will also receive a picture of your child’s brain!

Brain Imaging Study of Fluent and Dysfluent Speech

The Speech Neurophysiology Lab at the University of Michigan is recruiting children who stutter, including those who have stuttered in the past, as well as typically developing children to participate a research study (HUM00119337). The aim of this study is to investigate brain activity associated with speech production in children.

Your child may participate in this study if he/she is a native English speaker between 5-12 years old with no history of cognitive or neurological impairments.

Families may receive up to $220 for their time, including travel costs. In addition, the team provides, at no cost, a comprehensive report of your child’s speech and language.

Non-invasive brain stimulation in adults  who stutter

The Speech Neurophysiology Lab is recruiting adults who stutter to participate in a research study (HUM00134495) involving MRI brain scanning and high definition transcranial direct current stimulation (HD-tDCS), a safe, non-invasive form of brain stimulation. The study is conducted at the University of Michigan in Ann Arbor. Total study time is ~12 hours over 3 weeks, plus 1-month follow-up.Participants may receive $420 for their time. 

Eligibility: 1) right-handed, monolingual speaker of English, 2) between 18-65 years of age, 3) no history of neurological, language, hearing, cognitive, or speech impairments (other than stuttering for speakers who stutter), 4) not taking any medications affecting brain function such as those for anxiety, depression, or attention deficits, 5) no history of brain injury, and 6) can travel to Ann Arbor. If you are unsure if you meet these criteria, please contact us and we can discuss eligibility with you.
