Longitudinal study of brain development in children who stutter

This study involves collecting longitudinal data (behavioral, neuroimaging) from young children who stutter and their age-matched peers, starting from close to stuttering onset (ages 3 and up). Multiple acquisition of these data points from each child will enable us to examine brain developmental trajectories that differ between children who do and do not stutter, and further help elucidate factors that are associated with persistent forms of stuttering. We are also investigating how these brain and behavioral changes that correlate with persistent developmental stuttering differ between the two sexes.

These analyses will help us answer some long-standing questions about stuttering, such as: Why do some children recover naturally from stuttering while others don't? Why do more boys stutter than girls? 

The findings from this research have potential to lead to objective prognostic markers for persistent stuttering, and also lead to targeted treatment related research that may involve neuromodulation.

This research is funded through an NIDCD/NIH grant R01 DC011277 (PI Chang).

Rhythm perception and production in people who stutter

Combining behaviorial experiments, neuroimaging, and animal modeling (songbirds) methods, we are conducting parallel series of studies to investigate a novel rhythm deficit hypothesis in stuttering. This study is in collaboration with Drs. Devin McAuley, Juli Wade, and Laura Dilley at Michigan State University.

This study is funded by the Grammy Foundation and the RAIND (Research in Autism, Intellectual, and Neurodevelopmental Disabilities) pilot grant (PIs McAuley, Chang, Wade, Dilley).
