📰 ArXiv cs.AI

Mitigating perceptual impairment in multimodal large language models during reasoning tasks is crucial for improving their performance, and this can be achieved by addressing attention dispersion

advanced Published 21 May 2026
Action Steps
  1. Identify attention dispersion as a potential cause of perceptual impairment in MLLMs
  2. Analyze the visual attention of MLLMs during multi-step reasoning to detect drift from question-relevant regions
  3. Implement attention-focused training methods to mitigate attention dispersion and improve model focus
  4. Evaluate the effectiveness of mitigation strategies using visual question answering tasks
  5. Refine and adjust mitigation approaches based on evaluation results

Title: Deeper Thought, Weaker Aim: Understanding and Mitigating Perceptual Impairment during Reasoning in Multimodal Large Language Models

Abstract:
arXiv:2603.14184v2 Announce Type: replace-cross Abstract: Multimodal large language models (MLLMs) often suffer from perceptual impairments under extended reasoning modes, particularly in visual question answering (VQA) tasks. We identify attention dispersion as the underlying cause: during multi-step reasoning, the model's visual attention becomes scattered and drifts away from question-relevant regions, effectively "losing focus" on the visual input. To better understand this phenomenon, we an
