Distinct dynamics of conceptual and referential disruptions in human reading and large language model processing

The study investigates how disrupting conceptual versus referential information in short narratives affects human reading and large language model (LLM) processing. In humans, conceptual disruptions cause a strong, localized processing cost that peaks early and declines quickly, while referential disruptions produce weaker, gradually decreasing effects that are more influenced by sentence boundaries. In LLMs, both disruptions appear immediately at the manipulated word; surprisal patterns mirror human reading, whereas output-layer representations show that referential disruption initially causes a larger displacement before both types decay following a power-law.

Surprisal Theory is Tautological (without Rational Grounding)

Surprisal theory holds that the human processing difficulty of a linguistic unit in context is an affine function of its surprisal under some language model. I argue this claim is a tautology without further constraint: for any non-negative difficulty measure over units in context, there exists a language model whose surprisal is an affine function of it under mild technical conditions.

Lost but not erased: Finding traces of a forgotten language in neural speech models

The study investigates whether phonological traces of a first language persist in neural speech models after switching to a second language, mirroring phenomena observed in international adoptees. Using automatic speech recognition models trained on one language and then abruptly switched to another, researchers found that traces of the first language remained in the lowest, pre‑phonemic layers throughout second‑language training. These traces proved functional, as models with early exposure re‑learned their lost first language 14% faster than naive models, an advantage that vanished when the earliest layers were replaced with those from a non‑adopted model.

The Rise of Verbal Tics in Large Language Models: A Systematic Analysis Across Frontier Models

arXiv:2604. 19139v3 Announce Type: replace-cross Abstract: As Large Language Models (LLMs) continue to evolve through alignment techniques such as Reinforcement Learning from Human Feedback (RLHF) and Constitutional AI, a growing and increasingly conspicuous phenomenon has emerged: the proliferation of verbal tics--repetitive, formulaic linguistic patterns that pervade model outputs.
