LANGUAGE ACQUISITION, PROCESSING, AND PEDAGOGY LAB

We advance linguistic theory and improve language education

team meeting

Experimental Linguistics Research

Established in 2015, 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, the journal Language Learning, and the PROSEED/TEL CMU fund.

Active Student Learning

PhD, MA, and BA/BS 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 top graduate schools. Consider joining the lab!

Collaborative and Open Science

LAPP Lab stimuli, data, and code are made freely available on the Open Science Framework. Because team science is the best science, LAPP Lab collaborates with other labs and is part of the Pittsburgh Cognitive Auditory Neuroscience (PCAN) network.


LAPP Lab takes an interdisciplinary approach to understanding the mechanisms and architecture underlying language acquisition and processing. Our work bridges linguistics, psychology, speech science, and education, and aims to contribute real-world pedagogical innovations that improve language teaching and learning. The lab has two standing research groups: Psychling, the behavioral psycholinguistics group, and StatsEye, the R and eye-tracking group.

Interested in gaining research experience? Getting copies of papers or materials? Opening a dumpling lab? Or even participating in one of our studies? Contact the lab's director, Dr. Seth Wiener, for more information.

    Fall Ahead

    Lots of exciting things happening as we move into the second half of the fall semester. Our massive, multiyear, COVID-19 impacted study, "Incidental Nonspeech Auditory Learning Scaffolds Phonetic, Category, and Word Learning in a Foreign Language Classroom" has been tentatively accepted for publication! More to come along with a pre-print very soon. We have a new Italian eye-tracking study under review that we hope to share along with a study about dumplings! Stay tuned!
