arXiv:2606.29904v1 Announce Type: new Abstract: This study demonstrates an alignment of per-word processing time in a popular state-space language model Mamba and human readers. In Mamba, the recurrent state transition at each layer conceptually takes some duration of time, the discretization timestep $\Delta_t$, determined dynamically in response to the input. Using a naturalistic reading dataset, we show that the per-word timestep from Mamba is a significant predictor of human reading times, and remains significant even when known predictors such as GPT-2 surprisal are controlled for. We fur
The proliferation of advanced AI models like Mamba allows for deeper comparative analysis with human cognitive processes, driven by increased research into explainability and biological plausibility.
This research suggests that some AI models may be developing internal processing mechanisms that mirror human cognition, potentially indicating a path towards more intuitive and human-like AI understanding.
Our understanding of AI internal 'thought' processes becomes more measurable and comparable to human brain function, opening avenues for AI design inspired by cognitive science.

The finding strengthens the validity of Mamba-style architectures as biologically inspired and efficient.
Future AI development may prioritize architectures that exhibit similar quantifiable alignments with human cognitive metrics.
This could lead to a convergence of AI and neuroscience research, accelerating progress in both fields towards understanding intelligence.
