用代词提升新闻标题记忆度，但效果因内容而异。
Headlines You Won't Forget: Can Pronoun Insertion Increase Memorability?
- 通过实验测试第一、二人称代词对标题记忆的影响
- 240人参与，7680次判断显示代词影响记忆度不一
- 大模型自动插入代词常导致语义不准或风格生硬
为使新闻标题影响信念并推动行动，相关信息需被记住且可提取。本研究借鉴认知心理学实验设计，探究直接指涉（第一、二人称代词）这一语言特征对记忆度的影响，并评估大语言模型在不改变原意的前提下，精准插入该特征的可行性。三组受控记忆实验共招募240名参与者，产生7,680条独立记忆判断。结果表明，代词插入对记忆度影响复杂：其效果因标题主题、插入方式及上下文而异。探索性分析提示需进一步收集数据并进行细粒度分析，才能明确中介因素。此外，基于大模型的自动修订并不总合适：众包评估发现许多修改存在内容准确性不足、情感保留缺失或语风不自然的问题。研究数据已公开，供后续研究使用。
原文摘要 · Abstract (English)
For news headlines to influence beliefs and drive action, relevant information needs to be retained and retrievable from memory. In this probing study we draw on experiment designs from cognitive psychology to examine how a specific linguistic feature, namely direct address through first- and second-person pronouns, affects memorability and to what extent it is feasible to use large language models for the targeted insertion of such a feature into existing text without changing its core meaning. Across three controlled memorization experiments with a total of 240 participants, yielding 7,680 unique memory judgments, we show that pronoun insertion has mixed effects on memorability. Exploratory analyses indicate that effects differ based on headline topic, how pronouns are inserted and their immediate contexts. Additional data and fine-grained analysis is needed to draw definitive conclusions on these mediating factors. We further show that automatic revisions by LLMs are not always appropriate: Crowdsourced evaluations find many of them to be lacking in content accuracy and emotion retention or resulting in unnatural writing style. We make our collected data available for future work.
