Morten H. Christiansen

Morten H. Christiansen is the William R. Kenan, Jr. Professor of Psychology at Cornell University and holds a concurrent position as Professor of Cognitive Science at Aarhus University's School of Communication and Culture and the Interacting Minds Centre. His research focuses on the interplay between biological and environmental factors in language evolution, acquisition, and processing. Key methodologies include computational modeling, neuroimaging, and experimental psychology.

He is an elected member of Denmark’s and Norway’s Royal Academies of Sciences and a Fellow of the Association for Psychological Science and Cognitive Science Society. His work spans over 250 papers and four edited volumes, with his monograph The Language Game (2022) proposing a novel theory of language emergence through improvisation.

Research interests emphasize multiword chunking, statistical learning, and individual differences in language processing. Current projects explore Danish language challenges, computational models of cultural evolution, and the impact of large language models (LLMs) on human cognition.

Christiansen directs the Cognitive Science of Language Lab, teaches undergraduate and graduate courses (e.g., PSYCH 2150: Psychology of Language), and collaborates internationally on projects like the Danish Gigaword Corpus. His recent work highlights language as an emergent system shaped by interactive and ecological pressures.
