Clozing the Gap: Exploring Why Language Model Surprisal Outperforms Cloze Surprisal

arXiv:2601.09886v2 Announce Type: replace Abstract: How predictable a word is can be quantified in two ways: using human responses to the cloze task or using probabilities from language models (LMs).When used as predictors of processing effort, LM probabilities outperform probabilities derived from cloze data. However, it is important to establish that LM probabilities do so for the right reasons, since different predictors can lead to different scientific conclusions about the role of prediction in language comprehension. We present evidence for three hypotheses about the advantage of LM prob

Why this matters
Why now

The rapid advancement and integration of large language models (LLMs) into various applications necessitate a deeper understanding of their internal mechanisms and how they measure language predictability.

Why it’s important

For a strategic reader, insights into why language models outperform human-derived metrics for language processing are crucial for developing more effective AI systems and understanding human-AI cognitive interaction.
