What are the mechanisms underlying rapid, incremental on-line language comprehension? How do preschool children develop fast and interactive processing system that allows them to successfully employ multiple sources of information on-line? Do bilingual speakers to rely on two independent sets of processing mechanisms or is the nature of the bilingual processing system universal? The answers to these questions come from experimental studies in Dr. Sekerina's experimental psycholinguistic laboratory that utilize the free head eye-tracking technique in studying language processing in real time. Research in Dr. Sekerina's laboratory focuses on both adults and children, and on two languages, English and Russian. She is a recipient of an NSF ADVANCE grant designed to advance careers of women in science. A native of Moscow, Russia, she has taught at several East European summer schools and brings in a strong international perspective to her research and teaching.
