UPDATE: CORONAVIRUS RESPONSE

The Child Language Learning Center at Portland State University is happy to announce that we are back open. We are continuing to be cautious and taking all necessary precautions to keep our space safe for the time being. The lab is also currently looking for individuals to join the lab or participate in ongoing research studies. If you are interested or have any questions, please visit the Contact Us page or email us at ChildLLC@pdx.edu.

We hope that you are continuing to stay safe and healthy, feel free to access this list of community resources designed to be of assistance during COVID-19: COVID-19 Emergency Relief Resources for PDX (and beyond).

The Child Language Learning Center (CLLC) at Portland State University is directed by Dr. Carolyn Quam. The CLLC studies phonological development in monolingual and bilingual learners with and without Developmental Language Disorder (DLD) in preschoolers, adult language impairment, and adult second language learning. We conduct our research both in our lab at Portland State University and in the community. 

If you would like more information about our research or want to participate in a study, please visit the Contact US page or email us at childllc@pdx.edu.

Helpful Definitions:

Developmental Language Disorder: According to the American Speech-Language-Hearing Association, Developmental Language Disorder (DLD) is an impairment of comprehension and/or use of a language that impacts the individual's ability to function in academic, work or social settings (1993, p. 40). The difficulties cannot be otherwise explained by hearing or sensory impairments, motor impairments, or another medical or neurological condition.

Portland State is located on the traditional homelands of the Multnomah, Kathlamet, Clackamas, Tumwater, Watlala bands of the Chinook, the Tualatin Kalapuya, and many other indigenous nations of the Columbia River (hayásh-tsəqʷ  in the Chinook language). We acknowledge the ancestors of this place and understand that we are here because of the sacrifices forced upon them. By recognizing these communities, we honor their legacy, their lives, and the resiliency and ongoing contributions of their descendants.  


We encourage you to use the Native Land map to learn which indigenous communities are native to your area: https://native-land.ca/
