Brian MacWhinney
Brian MacWhinney is a cognitive psychologist whose computational models and shared language corpora connect research on language learning with AI and natural language processing. He studied geology and rhetoric at Berkeley, earned a psycholinguistics doctorate there in 1974, and taught at the University of Denver before joining Carnegie Mellon in 1981. With Elizabeth Bates, he developed the Competition Model; with Catherine Snow, he co-founded CHILDES in 1984 and extended it into TalkBank in 2001. A 2024 paper with Houjun Liu linked AI and machine-learning methods to cross-language analysis of CHILDES data, and his 2025 work included corpus tools with students and management of TalkBank. He received the 2026 Yuen Ren Chao Prize and, as of October 2026, is Teresa Heinz Professor of Cognitive Psychology at Carnegie Mellon.

Timeline
-
1961–1981
Berkeley, Denver, and CMU
At Berkeley, he studies geology and rhetoric and completes a 1974 Ph.D. in psycholinguistics. He becomes an assistant professor at the University of Denver in 1975 and joins CMU's Psychology department in 1981.
-
1984
Starting CHILDES
In 1984, he and Catherine Snow co-found the Child Language Data Exchange System (CHILDES) for the computational study of child-language transcripts.
-
2001
Extending TalkBank
In 2001, with NSF support, he helps extend CHILDES into TalkBank, a wider system of language databases that share CHAT transcription and CLAN analysis tools.
-
2014–2015
The Competition Model
With Elizabeth Bates, he develops the Competition Model, a computational account of grammar acquisition and sentence processing. His 2014 and 2015 edited volumes develop its Unified version, which connects first- and second-language learning through emergentist theory.
-
2024–2025
Applying AI to CHILDES
In a 2024 paper with Houjun Liu, he connects AI and machine-learning methods for speech recognition and NLP with cross-language study, and applies Universal Dependencies to CHILDES transcripts in 27 languages. By 2025, he manages NIH- and NSF-funded CHILDES and TalkBank corpora, including SLABank, and works with students on computational corpus tools and an online database for classroom interactions.
-
2026
A language science prize
In 2026, he receives the Yuen Ren Chao Prize in Language Science Lifetime Achievement Award.

As of October 2026
