Current Projects

 

MAPping 

A study on how children learn words with a focus on memory, attention, and the phonology of words (the way words sound).

Participate in research on how children learn language!  We are seeking families to participate in research related to how children learn language the skills that support language development. Children between the ages of 2 and 12 years may be eligible to participate. To learn more, contact us via email or by phone at 206-685-2202. Click here to see our flyer on autism research or here to see our flyer on fragile X syndrome research.

 

Expressive Language Sampling Study

The NeuDLL Lab at the University of Washington is conducting research on spoken language in children, adolescents, and young adults with autism in cooperation with two other sites in the United States. We are seeking individuals between 6 and 23 years old with autism spectrum disorder. To learn about participation, contact us via email or by phone at 206-685-2202. Click here to see our flyer.
