Abstract

from arXiv · show

Multimodal Large Language Models (MLLMs) have achieved remarkable success in open-vocabulary perceptual tasks, yet their ability to solve complex cognitive problems remains limited, especially when visual details are abstract and require visual memory. Current approaches primarily scale Chain-of-Thought (CoT) reasoning in the text space, even when language alone is insufficient for clear and structured reasoning, and largely neglect visual reasoning mechanisms analogous to the human visuospatial sketchpad and visual imagery. To mitigate this deficiency, we introduce Cognitive Supersensing, a novel training paradigm that endows MLLMs with human-like visual imagery capabilities by integrating a Latent Visual Imagery Prediction (LVIP) head that jointly learns sequences of visual cognitive latent embeddings and aligns them with the answer, thereby forming vision-based internal reasoning chains. We further introduce a reinforcement learning stage that optimizes text reasoning paths based on this grounded visual latent. To evaluate the cognitive capabilities of MLLMs, we present CogSense-Bench, a comprehensive visual question answering (VQA) benchmark assessing five cognitive dimensions. Extensive experiments demonstrate that MLLMs trained with Cognitive Supersensing significantly outperform state-of-the-art baselines on CogSense-Bench and exhibit superior generalization on out-of-domain mathematics and science VQA benchmarks, suggesting that internal visual imagery is potentially key to bridging the gap between perceptual recognition and cognitive understanding. We will open-source the CogSense-Bench and our model weights.

1 Introduction

The introduction identifies a gap between MLLMs’ strong visual perception and their ability to manipulate visual information, arguing that text-only reasoning can bottleneck visuospatial tasks. It presents Cognitive Supersensing, CogSense-Bench, and CogSense-Dataset as a framework for learning and evaluating visual cognitive reasoning.

1 Introduction

  • MLLMs can recognize and describe visual content but struggle to mentally manipulate it, while text-only CoT can bottleneck geometric and structured visual reasoning (Wei et al., 2022; Zhang et al., 2024c).The introduction gives abstract layouts, future transformations, shape rotation, dynamics simulation, and visual-rule induction as examples of difficult operations.Source: §1 · pp. 1–2
  • CogSense-Bench evaluates five dimensions—fluid and crystallized intelligence, visuospatial cognition, mental simulation, and visual routines—and reveals persistent weaknesses in state-of-the-art MLLMs, including with CoT prompting.The benchmark operationalizes visual cognition beyond perceptual recognition.Source: §1 · p. 2
  • Cognitive Supersensing adds an LVIP head that predicts answer-aligned visual latent sequences, then uses supervised fine-tuning and reinforcement learning to encourage coherent latent reasoning.The latent states are intended to preserve visual structure while language supplies high-level semantic guidance and final explanations.Source: §1 · p. 2
  • CogSense-8B achieves state-of-the-art performance across all tasks and 73.8% overall accuracy, surpasses GPT-5.2 by +33.5, and generalizes to challenging science and mathematics VQA benchmarks.The introduction also reports outperformance of strong baselines on broader science VQA benchmarks.Source: §1 · p. 2
  • CogSense-Dataset spans five categories and eleven subtasks and supports a multistage training pipeline that grounds intermediate visual latents toward the answer.Its supervised objective makes latent states predictive of the final answer’s visual representation; reinforcement learning optimizes latent-conditioned rollout trajectories.Source: §1 · p. 2, Figure 1 · p. 3, Figure 2 · p. 4

2 CogSense Dataset and Benchmark

CogSense-Dataset-105K and CogSense-Bench address the lack of systematic evaluation of high-level visual cognition beyond recognition. Their five cognitive dimensions include tasks requiring multi-step reasoning and manipulation of internal visual states.

Dataset and benchmark

  • CogSense-Dataset-105K and CogSense-Bench target the gap left by VQA benchmarks focused predominantly on semantic recognition or description.The dataset is described as comprehensive and large-scale, and the benchmark as a unified multi-task evaluation of high-level visual cognition.Source: §2 · p. 4

Cognitive categories

  • The benchmark evaluates five complementary dimensions: Fluid Intelligence, Crystallized Intelligence, Visuospatial Cognition, Mental Simulation, and Visual Routines.These theory-grounded categories are intended to capture distinct mechanisms of human visual reasoning, including abstract reasoning, spatial structuring, simulation, and attention-driven operations.Source: §2 · p. 4
  • Fluid Intelligence tests solving unseen problems, while Crystallized Intelligence assesses using learned world knowledge to abstract concepts across visual variation.Visuospatial Cognition probes reconstruction of structural relationships and decomposition of shapes; Mental Simulation infers hidden dynamics; Visual Routines assesses visual search and focused attention.Source: §2 · p. 4

Motivation

  • Because CogSense tasks require multi-step reasoning and answer-oriented internal visual states, the paper proposes Cognitive Supersensing to pair rationale generation with latent visual imagery prediction.The proposed approach is intended to support the simulation-like and stateful reasoning demanded by CogSense-Bench.Source: §2 · p. 4

3 Method

Cognitive Supersensing trains an MLLM to generate textual rationales and answers alongside answer-oriented latent imagery, using synthesized reasoning data, joint supervised learning, and rationale-focused reinforcement learning.

3.1 Preliminaries

  • The three-stage pipeline synthesizes reasoning chains, jointly trains text generation and latent imagery prediction, then uses latent rationales in reinforcement learning.The model processes visual and text tokens with a shared LLM backbone, whose text decoder generates the rationale and answer while an LVIP head predicts answer-oriented latent imagery.Source: §3.1 · p. 5

3.2 Stage I: Reasoning Chain Generation

  • A teacher MLLM generates step-by-step rationales and predicted answers, and chains with incorrect conclusions or hallucinated content are filtered out.The retained examples form an augmented dataset for supervised fine-tuning.Source: §3.2 · p. 5

3.3 Stage II: SFT with Latent Visual Imagery Prediction

  • LVIP predicts the ground-truth option image’s latent representation from pooled hidden states for option-image tokens, jointly with supervised text generation.The target is the frozen visual encoder embedding of the correct option image; the model minimizes an MSE loss alongside autoregressive cross-entropy, and the LVIP head can remain frozen at inference for optional grounding.Source: §3.3 · pp. 5–6

3.4 Stage III: RL with Latent Rationales

  • Diversity-seeking RL uses a Generative Flow Network to train rationale sampling toward a reward-induced posterior, combining answer evidence with LVIP representation grounding (Bengio et al., 2021, 2023; Lahlou et al., 2023; Zhang et al., 2022).A frozen supervised-model scorer supplies answer evidence, while a frozen LVIP head supplies the representation-level reward; flow matching trains the rationale policy rather than selecting a single deterministic chain.Source: §3.4 · pp. 6–7
  • Sparse anchor scores are interpolated between rationale prefixes for SubTB training, while reference-guided fine-tuning accepts trajectories meeting a relative evidence threshold (Madan et al., 2023).At inference, the model samples multiple latent rationales and selects the answer with the highest length-normalized frozen-scorer evidence score.Source: §3.4 · pp. 7–8
