儿童只需几次偶然的接触就可以学习新单词含义的各个方面，并且可以长时间保留这些知识，这一过程被称为“快速映射”(1-8) 人们通常认为快速映射是专用语言机制的结果，但这种能力也可能适用于语言学习以外的领域。在这里，我们提出了两个实验，其中三岁和四岁的儿童和成人被教导一个新的名称和一个关于物体的新事实，并测试他们的记忆力立即、延迟 1 周或延迟 1 个月后。我们的研究结果表明，快速映射并不局限于单词学习，这表明学习和保留新单词的能力是非特定于语言的学习和记忆能力的结果。
Children can learn aspects of the meaning of a new word on the basis of only a few incidental exposures and can retain this knowledge for a long period-a process dubbed 'fast mapping'(1-8) It is often maintained that fast mapping is the result of a dedicated language mechanism, but it is possible that this same capacity might apply in domains other than language learning, Here we present two experiments in which three- and four-year-old children and adults were taught a novel name and a novel fact about an object, and were tested on their retention immediately, after a 1-week delay or after a 1-month delay. Our findings show that fast mapping is not limited to word learning, suggesting that the capacity to learn and retain new words is the result of learning and memory abilities that are not specific to language.
