本文关注的是语言变化、语言习得、标记和语法表征之间映射的计算复杂性之间的相互作用。我们通过语言变化的计算模拟证明，标记可以在语言特征组合的分布中产生“空白”。某些组合不会发生，仅仅是因为有些组合在计算上不那么复杂。我们认为，在这种意义上，标记的一个贡献者是表面句法结构和概念结构之间映射的透明度程度。我们开发了一个粗略的复杂性度量，考虑到句法结构涉及到概念结构中关系的拉伸和扭曲的程度，我们展示了它如何在一些特定情况下给出正确的结果。
Our concern in this paper is with the interactions between language change, language acquisition, markedness, and computational complexity of mappings between grammatical representations. We demonstrate through a computational simulation of language change that markedness can produce ‘gaps’ in the distribution of combinations of linguistic features. Certain combinations will not occur, simply because there are combinations that are computationally less complex. We argue that one contributor to markedness in this sense is the degree of the transparency of the mapping between superficial syntactic structure and Conceptual Structure. We develop a rough measure of complexity that takes into account the extent to which the syntactic structure involves stretching and twisting of the relations that hold in Conceptual Structure, and we show how it gives the right results in a number of specific cases.
