个人如何改变语言

How individuals change language

摘要:

语言的出现和变化,随着时间的推移,在人口水平上,通过个人之间的相互作用的发言者。然而,很难直接观察到一个人的语言创新是如何促成整个人群的语言变化的,存在许多理论建议。我们介绍了一个非常普遍的数学模型,包括各种各样的个人层面的语言行为,并提供统计预测的人口水平的变化,从而导致他们。这个模型使我们能够比较在不同的假设下,个人学习和使用语言的方式在多种语言中的定冠词和不定冠词的变化的可能性。我们发现,语言变化的帐户,呼吁主要是在儿童语言习得的错误是非常弱的历史数据的支持,而那些允许扬声器在整个生命周期逐渐改变更合理,特别是当结合社会网络效应。

英文摘要:

Languages emerge and change over time at the population level though interactions between individual speakers. It is, however, hard to directly observe how a single speaker's linguistic innovation precipitates a population-wide change in the language, and many theoretical proposals exist. We introduce a very general mathematical model that encompasses a wide variety of individual-level linguistic behaviours and provides statistical predictions for the population-level changes that result from them. This model allows us to compare the likelihood of empirically-attested changes in definite and indefinite articles in multiple languages under different assumptions on the way in which individuals learn and use language. We find that accounts of language change that appeal primarily to errors in childhood language acquisition are very weakly supported by the historical data, whereas those that allow speakers to change incrementally across the lifespan are more plausible, particularly when combined with social network effects.
