難命名視覚刺激に対する連想創造性:人間とマルチモーダルLLMの比較
Testing Associative Creativity in Humans and Multimodal LLMs with Difficult-to-Name Visual Stimuli
抽象図形やノイズ画像など名付けにくい視覚刺激の説明において、人間とMLLMの連想創造性(独創性・有効性)を比較し、人間の方が意味的距離や多様性の高い記述を生成することを示した研究。

We investigate associative creativity in descriptions of abstract visual stimuli by humans and multimodal large language models (MLLMs). While conceptual association is central to human communication, it remains unclear how humans and models adapt when visual stimuli become increasingly difficult to map onto familiar semantic concepts. We evaluate several state-of-the-art MLLMs and human participants along two dimensions of creativity, originality and effectiveness, using two datasets with controlled manipulations of difficulty. SilCC varies naming difficulty through progressively more complex combinations of abstract shapes, and PixCC varies difficulty through increasing levels of random visual noise. Results show that humans produce more diverse associative descriptions than MLLMs, including greater semantic distance, higher entropy, and more novel expressions relative to reference lexica. As difficulty increases, effectiveness declines in SilCC, and humans increasingly shift from holistic associations to descriptions of low-level visual properties in PixCC.
