Research Interests

Judith Kroll is Distinguished Professor of Psychology, Linguistics, and Women’s Studies and Director of the Center for Language Science at Pennsylvania State University ( She completed her undergraduate work at New York University and her graduate work at Brandeis University. She previously held faculty positions at Mount Holyoke College, Rutgers University, and Swarthmore College. Together with Annette de Groot, she co-edited Tutorials in Bilingualism: Psycholinguistic Perspectives (1997, Erlbaum) and the Handbook of Bilingualism: Psycholinguistic Approaches (2005, Oxford). She served as a co-editor of Bilingualism: Language and Cognition from its founding in 1997 until 2001 and its coordinating editor from 2001-2002. She serves on a number of editorial boards, including Journal of Memory and Language, Journal of Experimental Psychology: Learning, Memory, and Cognition, International Journal of Bilingualism, Journal of Cognitive Psychology, and Psychological Science. The research that she and her students conduct concerns the acquisition, comprehension, and production of two languages during second language learning and in proficient bilingual performance. Their work, using behavioral and neurocognitive methods, is supported by grants from the National Science Foundation and the National Institutes of Health.  She is the PI on a recently awarded PIRE grant from NSF (Partnerships for International Research and Education) to develop an international research network and program of training to enable Penn State students at all levels (undergraduate, graduate, and postdoctoral) and early career faculty to  pursue research abroad on the science of bilingualism (  She was one of the founding organizers of Women in Cognitive Science, a group developed to promote the advancement of women in the cognitive sciences and supported by the National Science Foundation (
