AI-assisted writing raises concerns about autonomy and ownership when benefiting writers. Personalization has been proposed as an effective solution while also risking writers' reliance on AI and behavior shifting. For better personalization design, existing studies rely on interaction and information solely within the writing phase; however, few studies have examined how reading behaviors can inform personalized writing. This study investigates the effects of integrating reading highlights for personalization on AI-assisted writing. A between-subjects study with 46 participants revealed that the personalization condition encouraged participants to produce more highlights. However, highlighting unexpectedly shifted from a sense-making strategy to an instrumental act of "feeding the AI," leading to significant reliance on AI and declines in writers' sense of autonomy, ownership, and self-credit. These findings indicate personalization risks in AI-assisted writing, emphasize the importance of personalization strategies, and provide design implications.

翻译：人工智能辅助写作在为作者带来便利的同时，也引发了关于自主性与所有权的担忧。个性化被视为一种有效的解决方案，但也存在导致作者过度依赖AI及行为模式转变的风险。为优化个性化设计，现有研究仅依赖于写作阶段内的交互与信息；然而，鲜有研究探讨阅读行为如何为个性化写作提供参考。本研究探究了整合阅读标注信息用于个性化对AI辅助写作的影响。一项包含46名参与者的组间对照实验显示，个性化条件促使参与者生成了更多标注。然而，标注行为意外地从一种意义建构策略转变为“喂养AI”的工具性行为，导致对AI的显著依赖，并削弱了作者的自主感、所有权意识与自我成就感。这些发现揭示了AI辅助写作中的个性化风险，强调了个性化策略的重要性，并为设计提供了启示。
