AI写作助手会削弱作者归属感，但个性化设计可部分修复。
Who Owns the Text? Design Patterns for Preserving Authorship in AI-Assisted Writing
- 提供按需句级建议，结合角色引导与风格定制
- 风格个性化使归属感提升0.43分，AI内容采纳率增5个百分点
- 提出五种保留作者身份的设计模式，适合教育/专业写作工具
AI写作助手可降低负担并提升流畅度，但可能削弱作者的归属感。我们通过一款具备归属感知功能的协同编辑器，测试了两种常见设计：基于角色的指导和风格个性化。在一项在线研究中（N=176），参与者完成三项专业写作任务：无AI协助的邮件、使用通用AI建议的提案，以及采用角色引导的求职信。其中一半人接收到根据其过往写作风格定制的建议。在两种AI辅助任务中，心理归属感相比无辅助写作下降约0.85-1.0分（7分量表），尽管认知负荷降低约0.9分，整体质量评分保持相似。角色引导未能阻止归属感下降；而风格个性化部分恢复归属感（+0.43分），并提高AI内容采纳率（+5个百分点）。我们提炼出五种设计模式：按需启动、微建议、声音锚定、受众支架、决策点溯源，以指导保有作者身份的写作工具开发。
原文摘要 · Abstract (English)
AI writing assistants can reduce effort and improve fluency, but they may also weaken writers' sense of authorship. We study this tension with an ownership-aware co-writing editor that offers on-demand, sentence-level suggestions and tests two common design choices: persona-based coaching and style personalization. In an online study (N=176), participants completed three professional writing tasks: an email without AI help, a proposal with generic AI suggestions, and a cover letter with persona-based coaching, while half received suggestions tailored to a brief sample of their prior writing. Across the two AI-assisted tasks, psychological ownership dropped relative to unassisted writing (about 0.85-1.0 points on a 7-point scale), even as cognitive load decreased (about 0.9 points) and quality ratings stayed broadly similar overall. Persona coaching did not prevent the ownership decline. Style personalization partially restored ownership (about +0.43) and increased AI incorporation in text (+5 percentage points). We distill five design patterns: on-demand initiation, micro-suggestions, voice anchoring, audience scaffolds, and point-of-decision provenance, to guide authorship-preserving writing tools.
