Preschoolers' use of number words to denote one-to-one correspondence was assessed by 2 tasks. In the matching task, the children matched 2 sets to determine whether they could be put in one-to-one correspondence and then judged whether the same number word should be used to denote both sets. In the counting task, the children counted 2 sets and used the final number words of the count to determine whether the sets could be put in one-to-one correspondence. Most 4-year-olds and some 3 1/2-year-olds use number words to denote one-to-one correspondence in each of these tasks. These findings are related to previous research.
通过两项任务评估了学龄前儿童使用数字词来表示一一对应的情况。在匹配任务中，孩子们将两组物品进行匹配，以确定它们是否可以形成一一对应关系，然后判断是否应该用同一个数字词来表示这两组物品。在计数任务中，孩子们数两组物品，并使用计数的最后一个数字词来确定这两组物品是否可以形成一一对应关系。大多数4岁儿童和一些3岁半儿童在这些任务中都使用数字词来表示一一对应关系。这些发现与之前的研究相关。
