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, 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.

Research Opportunities:

We are looking for a few enthusiastic undergraduates who would like to work in the lab with us on new projects.

Our lab conducts research on the cognitive processes that support the acquisition and proficient use of a second language. (for more information see our research page.) However, there is no requirement to speak a second language yourself. The only requirement is to be interested in gaining research skills and in being part of an interactive lab group.

For more information, please refer to the Purple Lab Website

Active Funding

National Institutes of Health Grant, R01-HD053146: Cognitive processes in bilinguals (Co-PIs, Chip Gerfen, Taomei Guo, and Maya Misra), 2008-2013

The goal of this project is to use converging methods (ERPs, behavioral measurements, and acoustic measurements of speech) to identify the way in which bilinguals select the intended language in spoken production.

National Science Foundation Grant, BCS-0955090: Language Processing in bilinguals (Co-PIs Paola Dussias, Janet Van Hell, Ana Schwartz, 2010-2013

The goal of this research is to investigate the conditions that enable bilinguals to select the intended language when words and grammatical structures in both languages are available and to determine how some sentence contexts restrict language processing to one language alone but others encourage code switching between the bilingual’s two languages.

National Science Foundation Grant, OISE-0968369: PIRE (Partnerships in International Research and Education): Bilingualism, mind, and brain: An interdisciplinary program in cognitive psychology, linguistics, and cognitive neuroscience (Co-PIs Paola Dussias, Ping Li, Janet van Hell), 2010-2015

The goal of the PIRE is to develop a training program in coordination with an international research network of collaborators to enable undergraduates, graduate students, post doctoral fellows, and early career faculty to conduct research abroad.
