Henri Kauhanen

Hi, and welcome! My name is Henri, and I am a complex systems scientist working on linguistic variation and change. I formulate and study mathematical models to try to figure out what is and what isn’t universal in the dynamics of human language.

Selected papers

A bifurcation threshold for contact-induced language change

Glossa: a journal of general linguistics, 7(1), 1–32 (2022)

The fraction of L2 (second-language) learners present in a speech community must exceed a critical threshold for L2-difficult features to be lost.

Geospatial distributions reflect temperatures of linguistic features

Henri Kauhanen, Deepthi Gopal, Tobias Galla & Ricardo Bermúdez-Otero

Science Advances, 7, eabe6540 (2021)

The propensity of features of language to change can be measured using a temperature-like quantity.

Replicator–mutator dynamics of linguistic convergence and divergence

Royal Society Open Science, 7, 201682 (2020)

Sociolinguistic identity maintenance can be understood as a population game with nonlinear fitness.

Stable variation in multidimensional competition

The Determinants of Diachronic Stability (Benjamins) (2019)

Stable variation can arise when multiple grammars compete.

Deriving the Constant Rate Effect

Henri Kauhanen & George Walkden

Natural Language & Linguistic Theory, 36(2), 483–521 (2018)

The Constant Rate Effect, or something like it, arises from the interplay of variational learning and production biases.

Neutral change

Journal of Linguistics, 53(2), 327–358 (2017)

Changes can be well-behaved even if they are selectively neutral.

Manuscripts

Language structure is influenced by the proportion of non-native speakers: a reply to Koplenig (2019)

Henri Kauhanen, Sarah Einhaus & George Walkden

(2022)

When non-vehicular languages for which no direct estimate of L2 speaker proportion exists are treated as missing data, a correlation between the proportion of L2 speakers and language complexity is found.
