In the Child Language Learning Center (CLLC), we are trying to understand the language-learning process for monolingual and multilingual learners from infancy through adulthood. One phenomenon we are very interested in is the fact that young children pay attention to a variety of aspects of their language, even aspects that are not used in their native language. We believe this flexibility when paying attention to language is a crucial part of learning new language structure. We are interested in how this flexibility changes across development, how it differs for children and adults who have language-based learning disabilities, and how it differs in multilinguals with varying degrees of proficiency in each language. Our interests in multilingualism also extend to broader contextual factors that support or undermine families' ability to pass on their home language to children. Currently, the CLLC has two projects in active data collection exploring these ideas, which are summarized below. We are also working on additional projects, including a scoping review of the literature on factors that support or undermine heritage-language maintenance.
The bilingualism group is expanding upon previous research conducted by Dr. Quam and Dr. Sarah Creel at UC San Diego with Mandarin-English bilingual adult participants. The primary goal of the research is to learn about how experience with English for native speakers of Mandarin Chinese affects their sound processing in their native language. We are excited to use our EyeLink eye-tracker to test our hypotheses, continuing this line of research right here at Portland State University! If you are a native speaker of Mandarin and are interested in participating, please check out our Participate page!
As a trusted resource, pediatricians, teachers, speech-language pathologists, and other educational, health, and medical providers regularly field questions from parents outside their area of expertise. This may include questions on bilingual language input, language delays, and language disorders. We are currently collecting information on service providers' knowledge and beliefs surrounding language development in children, as well as their experiences discussing language development concerns with families. Our survey attempts to gain insight into the speech and language concerns brought forth by families and to better understand the information given in response to these concerns. If the first phase of the study shows there are gaps in knowledge on the part of service providers, the second phase may involve the creation of language development training modules.
