语言需要通过内部表征的中介将符号（单词、句子）与物理世界联系起来的能力，这一过程被称为符号基础。认知科学中最大的争论之一是人类大脑是如何做到这一点的。我们需要物质解释还是系统解释？约翰·塞尔（John Searle）著名的“中文房间”（Chinese Room）思想实验继续产生大量争论和反争论的文献，该实验认为，自主建立对世界的内部表征（在哲学术语中称为“意向性”）是基于人类神经组织的特殊属性，因此，人工系统，如自主的物理机器人，永远无法实现这一点。在这里，我们将命名游戏作为符号交互的一个特殊例子来研究，并研究一个动态系统，该系统自主建立和使用在游戏中表现所必需的符号网络。我们在物理机器人的真实实验中证明，这样一个动态系统确实导致了一个成功的紧急通信系统，因此，符号基础和意向性可以用一种特定的系统动力学来解释。人类大脑显然有参与这种动态的正确机制，但同样的动态也可以体现在其他类型的物理系统中。
Language requires the capacity to link symbols (words, sentences) through the intermediary of internal representations to the physical world, a process known as symbol grounding. One of the biggest debates in the cognitive sciences concerns the question how human brains are able to do this. Do we need a material explanation or a system explanation? John Searle’s well known Chinese Room thought experiment, which continues to generate a vast polemic literature of arguments and counter-arguments, has argued that autonomously establishing internal representations of the world (called ’intentionality’ in philosophical parlance) is based on special properties of human neural tissue and that consequently an artificial system, such as an autonomous physical robot, can never achieve this. Here we study the Grounded Naming Game as a particular example of symbolic interaction and investigate a dynamical system that autonomously builds up and uses the semiotic networks necessary for performance in the game. We demonstrate in real experiments with physical robots that such a dynamical system indeed leads to a successful emergent communication system and hence that symbol grounding and intentionality can be explained in terms of a particular kind of system dynamics. The human brain has obviously the right mechanisms to participate in this kind of dynamics but the same dynamics can also be embodied in other types of physical systems.
