Research
Researchers at the Center for the Study of Learning (CSL) use behavioral and neuroimaging data to investigate a variety of topics regarding learning and learning disabilities.
Current Research Topics
Reading & Reading Disability (Dyslexia)
We conduct behavioral and neuroimaging research to examine how typical reading occurs in the brain and to better understand the origins of developmental dyslexia. We compare neuroimaging data of people with dyslexia to typical readers to characterize differences in brain function and structure. We also examine how training or intervention programs lead to changes in behavior and the brain.

Language Experience: Bilingualism
We conduct research to examine how language experience (specifically bilingualism) affects brain structure and function. We also study the interaction between bilingualism and reading ability, and other cognitive skill sets such as executive functioning.

Math & Math Disability (Dyscalculia)
We conduct behavioral and neuroimaging research to understand the relationship between math and reading in the brain, particularly in those with learning disabilities. Using training interventions and neuroimaging methods, we seek to understand the brain bases of math learning disabilities (dyscalculia) and to investigate the bases of comorbidity between math and reading disabilities.

Past Projects & Research Topics
Spelling
We've studied the neural basis of spelling, and how reading and spelling may have shared and distinct neural representations.

Sensorimotor Systems
We've examined how sensorimotor systems develop and how they may be linked to reading and dyslexia.

Sensory Experience: Deafness
We've conducted research that examines how sensory experience (e.g. deafness) is related to neuroplastic differences in the brain.
