优选句法理论与原则——参数理论的比较

原则——参数理论因不承认普遍语法原则之间的冲突,普遍语法原则本身的不可违背性和参数设定的一次性等而使得理论的普遍解释性受到削弱。在优选音系学基础上发展起来的优选句法理论是以制约条件为基础的表征式理论,它以其普遍性、可违反性、和谐性、严格层级性和分析的自由性等特点能更好地解释语言的类型学效果,更好地解决普遍语法原则之间的冲突,并在儿童语言的“非忠实性产出”和相对“忠实性理解”之间建立直接的连接关系。

A Comparison Between Optimality-Theoretic Syntax and the Principles-and-Parameters Theory

The principles-and-parameters theory assumes that there are not conflicts among the principles of Universal Grammar and that the UG principles cannot be violated, the parameters＇ setting has the effect of ＂once and for all＂, which reduces the general explanatory force of the theory. The optimality-theoretic syntax developed on the basis of optimality phonology is a kind of representational theory based on the universal constraints, the characteristics of universality, violability, harmonic evaluation, strict domination and the freedom of analysis in OT Syntax can more systematically explain the effect of human languages establish a direct connection between the ＂non-faithful ＇ typology, solve the conflicts among UG principles and production＂ and the relative ＂faithful comprehension＂ in child language.
