人类交流系统在文化上进化，但推动这种进化的进化机制还没有被很好地理解。根据通讯变量遵循中性进化动态在种群中传播的基线(也称为漂移模型)，我们测试了两种文化选择模型的作用：协调偏向和内容偏向。我们构建了一个在四个8人实验室微型社会中进行简单交流游戏的交流变量传播的参数化混合概率模型。我们发现，选择主义模型结合在一起，解释了大部分经验数据。最合适的参数设置包括以自我为中心的偏见和内容偏见，这表明参与者保留了他们自己以前使用的交际变量，除非他们遇到了更好的(内容偏见的)变量，在这种情况下，他们被采用了。这一新的结果模式表明：(I)人类通信系统的文化进化理论必须整合选择主义模型；(Ii)人类通信系统是功能自适应的复杂系统。
Human communication systems evolve culturally, but the evolutionary mechanisms that drive this evolution are not well understood. Against a baseline that communication variants spread in a population following neutral evolutionary dynamics (also known as drift models), we tested the role of two cultural selection models: coordination- and content-biased. We constructed a parametrized mixed probabilistic model of the spread of communicative variants in four 8-person laboratory micro-societies engaged in a simple communication game. We found that selectionist models, working in combination, explain the majority of the empirical data. The best-fitting parameter setting includes an egocentric bias and a content bias, suggesting that participants retained their own previously used communicative variants unless they encountered a superior (content-biased) variant, in which case it was adopted. This novel pattern of results suggests that (i) a theory of the cultural evolution of human communication systems must integrate selectionist models and (ii) human communication systems are functionally adaptive complex systems.
