沟通涉及很多不确定性。因此，从表面上看，令人惊讶的是，从细胞到人类的生物通信系统表现出高度的模糊性，并且经常将其解决方案留给上下文线索。一旦我们考虑到情境信息可能在个体之间存在差异，这个难题就会加深。在下文中，我们提出了一个模糊的沟通模型，在缺乏共同的上下文先验的主观理性代理之间的迭代交互。我们认为歧义的正当性在于赋予对话者灵活地调整语言使用的手段，以满足他们的交际偏好。语言对齐在这一过程中起着重要的作用，它促进了语境期望的趋同，从而导致对歧义信息的一致使用和解释。我们的结论是，歧义是生态合理的，当（i）对话者的（信念）上下文的期望一般是一致的，或（ii）他们互动多次在一个信息的背景下，使他们的期望对齐。根据这些结果，意义的多样性可以被理解为一种机会主义的结果，由语言顺应和语境信息促成和塑造。1.沟通中的多重性2。通过语用推理的歧义信号2.1. 2.2.信号行为2.3.沟通成功2.4.迭代交互3.单次和迭代交互的预测3.1.模拟3.2.探索和过去的经验3.3.先发制人的适应4.讨论5.结论附录交际中的意义多重性通过语用推理的歧义信号传递2. 1. 2.2.信号行为2.3.沟通成功2.4.迭代交互信号传递行为迭代交互单一和迭代交互的预测3.1.模拟3.2.探索和过去的经验3.3.探索和过去的经验
Communication involves a great deal of uncertainty. Prima facie, it is therefore surprising that biological communication systems—from cellular to human—exhibit a high degree of ambiguity and often leave its resolution to contextual cues. This puzzle deepens once we consider that contextual information may diverge between individuals. In the following we lay out a model of ambiguous communication in iterated interactions between subjectively rational agents lacking a common contextual prior. We argue ambiguity’s justification to lie in endowing interlocutors with means to flexibly adapt language use to each other and the context of their interaction to serve their communicative preferences. Linguistic alignment is shown to play an important role in this process; it foments convergence of contextual expectations and thereby leads to agreeing use and interpretation of ambiguous messages. We conclude that ambiguity is ecologically rational when (i) interlocutors’ (beliefs about) contextual expectations are generally in line or (ii) they interact multiple times in an informative context, enabling for the alignment of their expectations. In light of these results meaning multiplicity can be understood as an opportunistic outcome enabled and shaped by linguistic adaptation and contextual information. 1.
