Researchers have introduced Spatial-IQ, a new hierarchical framework designed to deconstruct and test the spatial reasoning capabilities of multimodal large language models (MLLMs). This framework breaks down object counting in 3D structures into nine distinct perceptual and cognitive sub-tasks, mirroring human spatial cognition development. By evaluating models on these sub-tasks, Spatial-IQ reveals that top-performing models often achieve high accuracy on the main task without mastering the foundational sub-tasks, indicating potential shortcut behaviors. The study also demonstrates that training MLLMs using chain-of-thought supervision on these hierarchical sub-tasks, coupled with reinforcement learning, significantly enhances both spatial consistency and overall accuracy.
