About Us

Our lab conducts research on the cognitive processes that support the acquisition and proficient use of a second language. Our research investigates how bilingual speakers manage to speak words in one language at a time, how adult learners of a second language acquire new vocabulary, and what information is available when proficient bilinguals read in one or both of their two languages.

Our lab's principal investigator is Dr. Judith Kroll.

For more information, feel free to explore our website or contact any of our lab members with questions.
