MultivationBench: A Benchmark for Multimodal Sequential Motivation Reasoning Researchers introduced MultivationBench, a benchmark for evaluating multimodal sequential motivation reasoning in story-driven visual narratives, built on Maslow's hierarchy and Reiss's basic desires. Testing showed all models struggled to maintain consistent motivation reasoning across sequential contexts, revealing a gap between static recognition and dynamic reasoning. arXiv:2607.26465v1 Announce Type: new Abstract: Multimodal Large Language Models have sparked significant interest due to their potential for social intelligence; however, their ability to perform sequential motivation reasoning remains insufficiently studied. Existing evaluations predominantly examine static text or isolated visual snapshots, which do not reflect the cumulative nature of real-world behavioral drivers. To address this gap, we introduce MultivationBench, a benchmark designed to rigorously evaluate multimodal motivation reasoning within story-driven visual narratives. The benchmark builds upon established psychological frameworks - Maslow's hierarchy and Reiss's basic desires - and requires models to integrate accumulated multimodal context to infer evolving motivations. Results indicate that MultivationBench presents a significant challenge: all tested models struggle to maintain consistent motivation reasoning across sequential contexts, revealing a critical disconnect between static recognition capabilities and the dynamic reasoning essential for human-like social understanding.
