Quantifying Cross-Linguistic Effects of Syncretism on Agreement Attraction Using LLM Processing Proxies

This paper investigates why morphological syncretism amplifies agreement attraction errors in some languages (English, German, Russian) but not others (Turkish, Armenian), a pattern lacking a principled account. The authors use surprisal and attention entropy derived from large language models as proxies for human sentence processing across four languages. LLM-derived measures successfully replicate behavioral findings in English and German, align with Turkish null results, and partially capture Russian patterns. The work demonstrates LLMs as tools for cross-linguistic psycholinguistic investigation.
