Noisy memory encoding explains negative polarity illusions

arXiv:2606.04340v1 Announce Type: new Abstract: A sentence like "The authors that no critics recommended have ever received acknowledgment for a best-selling novel" is sometimes rated as acceptable even though, strictly speaking, it is ungrammatical because the negative polarity word "ever" is not licensed where it is. This behavioral effect is sometimes called a "negative polarity illusion". Here we propose that the lossy context surprisal theory of Hahn et al. (2022) -- whereby people have an imperfect encoding of complex sentences -- might explain this effect. We hypothesize that people hav

Why this matters
Why now

This paper leverages recent theoretical advancements (Hahn et al., 2022) to explain long-standing linguistic phenomena through cognitive limitations, demonstrating the iterative nature of scientific progress in AI and cognitive science.

Why it’s important

A strategic reader should care because improving our understanding of how humans process language, including their 'errors,' is crucial for developing more robust and human-like AI language models and for advancing cognitive science.

What changes

This research provides a cognitive explanation for 'negative polarity illusions,' shifting the understanding from simple grammatical errors to a principled outcome of imperfect cognitive encoding, which can inform future AI model design.

    Direct

    This research contributes to the theoretical understanding of human language processing and its limitations.

    Second

    It could inspire new approaches to designing AI models that explicitly account for 'lossy' or imperfect information encoding, potentially leading to more human-like language understanding or generation.

    Third

    These insights might lead to AI systems that are better at interpreting ambiguous or non-standard human communication by understanding the cognitive shortcuts or biases that lead to such expressions.
