In the Language, Attention & Cognitive Engineering (LACE) laboratory, one focus of our research has been understanding the effects of bilingualism on various aspects of cognition: executive attention, cognitive control, ambiguity resolution, and lexical retrieval. Another focus is understanding the effects of other special experiences and skills (e.g., music, mindfulness, video gaming, multitasking, exercise) on cognitive ability. To this end, we implement both behavioral and self-report measures to investigate cognitive architectures underlying human information processing.


LACE Lab location: EP 513

Undergraduate and graduate students are welcome to join the lab. Students can earn 1-3 credits of supervised selected research for active participation in the lab. Those who would like to join, reach out to Dr. Paap directly via e-mail and include a letter of interest.
