AI让设计更新颖但未必更好用，且影响不同人群的创意思维。
Creativity in the Age of AI: Evaluating the Impact of Generative AI on Design Outputs and Designers' Creative Thinking
- 对比有无AI辅助设计，发现AI提升设计新颖性却未改善实用性。
- 专家评价：AI生成设计更独特（“weird”），但视觉和品牌契合度无差异。
- 新手设计师创意更活跃，英语母语者使用时反而更紧张。
随着生成式AI（GenAI）日益融入设计流程，其对设计成果及设计师创意思维的影响亟待研究。我们开展了一项被试内实验，让参与者在有无GenAI支持下设计广告。结果表明，专业评审认为使用GenAI的设计更具创意和非传统性（“weird”），尽管在视觉吸引力、品牌契合度或实用性方面无显著差异，这揭示了在GenAI情境下，新颖性与实用性这一传统创造力双要素出现脱钩。此外，尽管GenAI未显著提升整体创意思维能力，用户反应因母语和先前AI使用经验而异：英语母语者使用AI时放松度下降，而首次接触GenAI的设计师则在发散思维（如想法流畅性与灵活性）上有所提升。这些发现凸显了GenAI对不同群体影响的差异性，提示个性化AI工具的潜力。
原文摘要 · Abstract (English)
As generative AI (GenAI) increasingly permeates design workflows, its impact on design outcomes and designers' creative capabilities warrants investigation. We conducted a within-subjects experiment where we asked participants to design advertisements both with and without GenAI support. Our results show that expert evaluators rated GenAI-supported designs as more creative and unconventional ("weird") despite no significant differences in visual appeal, brand alignment, or usefulness, which highlights the decoupling of novelty from usefulness-traditional dual components of creativity-in the context of GenAI usage. Moreover, while GenAI does not significantly enhance designers' overall creative thinking abilities, users were affected differently based on native language and prior AI exposure. Native English speakers experienced reduced relaxation when using AI, whereas designers new to GenAI exhibited gains in divergent thinking, such as idea fluency and flexibility. These findings underscore the variable impact of GenAI on different user groups, suggesting the potential for customized AI tools.
