记忆衰退让语言协作更稳定，但会延迟真实共识的达成。
Forgetting Our Way to Shared Meaning: Effects of Forgetting on Conceptual Alignment in a Non-Partnership Coordination Game
- 用非合作博弈模拟语言共识演化，考察记忆与适应性影响
- 适应性玩家更快达成真实共识，非适应者误以为早达成
- 随时间弱化新信息权重，能提升共识稳定性，适合长期协作
语言共享意义依赖于人们对概念范畴的学习与一致。本文研究个体记忆特性如何影响群体中共享意义的出现与演变。传统语义模型缺乏对群体协作中意义形成机制的解释，且多基于合作型博弈假设。本文构建非合作博弈框架，通过不同适应性与记忆衰退水平的智能体进行反事实模拟，揭示实际与感知共识之间的差异。结果表明：适应性玩家实现真实共识更快，最终概念区域更接近；而非适应性玩家过早感知到共识。随时间减弱新信息权重，比固定权重更能促进共识稳定。记忆特征在实际与感知共识的演化中起关键作用。
原文摘要 · Abstract (English)
Shared meaning in language requires people to learn and agree on categories. We ask how characteristics of agents' memories change the emergence and evolution of shared meaning. Without a coordination game, models of conceptual semantics cannot explain how shared meaning emerges and changes in groups of people; however, existing games assume that players share payoffs in a partnership setting. We model conceptual alignment as a non-partnership game and illustrate differences in actual and perceived conceptual convergence from counterfactual simulations using agents with varying levels of adaptiveness and memory degradation. We found that adaptive players achieved actual convergence faster and had closer final conceptual regions than non-adaptive players, while non-adaptive players perceived convergence earlier. Weighing novel information less over time resulted in more stable agreements than fixing the weight of novel information. Memory features are critical to the emergence and evolution of actual and perceived convergence.
