自罗杰·布朗 (Roger Brown) 于 1957 年对单词学习进行开创性研究以来，大多数词汇习得的实验研究都关注快速映射：建立新词汇条目的过程，以及新听到的单词的语言上下文的表示与其非语言上下文的表示相互作用以固定初始部分含义的过程。这里我重点关注随后的扩展过程，通过该过程来近似成人的含义。有两个因素会导致学习过程延长；假设空间的大小以及有时需要创建新的语义原语。有时词汇学习需要概念上的改变。我概述了一个可以实现这一目标的学习机制。学习动词数字含义的案例研究说明了这一论点。
Since the seminal 1957 studies of word learning by Roger Brown, most experimental studies of lexical acquisition have concerned fast mapping: the process through which a new lexical entry is established, and through which representations of the linguistic context of a newly heard word interact with representations of its nonlinguistic context to fix an initial partial meaning. Here I focus on the subsequent extended process through which the adult meaning is approximated. Two factors lead to an extended learning process; the size of the hypothesis space and the need, sometimes, for the creation of new semantic primitives. Sometimes lexical learning requires conceptual change. I sketch a learning mechanism through which this can be achieved. A case study of learning the meanings of verbal numerals illustrates the argument.
