LANGUAGE ACQUISITION, PROCESSING, AND PEDAGOGY LAB
We advance linguistic theory and improve language education
LAPP Lab carries out behavioral and eye-tracking research. Our research is generously supported by the National Science Foundation, the National Institutes of Health, Duolingo, Language Learning, and the PROSEED/TEL CMU fund.
Ph.D., M.A., and B.A./B.S. students take part in research, conference presentations, and journal publications. Grad students have gone on to tenure-track, post-doc, and industry positions. Undergrads have gone on to graduate school and industry positions.
Stimuli, data, and code are made freely available on the Open Science Framework. Our published research is free to read and download.

We finally published our dumpling study in JASA Express Letters. For the rest of my life, I can tell people that I have published on dumplings, one of life's greatest foods. This is a small but tasty victory. Who says experimental linguistics cannot be delicious?

The lab has a new web-based eye-tracking study on the perception of sincere and sarcastic speech. We will be presenting it at Speech Prosody 2026 in Philadelphia this May. Come say hi!
We continue to test the limits of advantageous transfer and our additive model of speech perception. tl;dr: it's complicated.
