使用Thomas等人提出的信号检测范式对儿童早期语言理解进行了两项研究。(1981)。实验一复制了Thomas等人的原始发现，表明13个月大的婴儿理解父母报告他们会理解的单词，而不理解父母报告他们不理解的单词。在实验2中，对程序进行了修改，以测试早期语言理解中的过度延伸。在一半的实验中，孩子们看到了一系列物体，其中包括一个“已知单词”的指代。在另一半上，数组包括一个物体，它在感知上与已知单词的指称相似，但本身不是合适的指称(例如，苹果而不是橙子)。虽然孩子们表现出了对已知单词的理解，但他们也过度使用了这个词来表示不恰当的指称。我们讨论了这种过度延伸的机制，以及理解和产出之间的一般关系。
Two studies of children's early language comprehension were performed using the signal detection paradigm introduced by Thomas et al. (1981). Experiment 1 replicated the original findings of Thomas et al., demonstrating that 13-month-olds understand a word that a parent reported they would understand and did not understand a word that a parent reported they would not. In Experiment 2, the procedure was modified to test for overextensions in early language comprehension. On half of the trials, children saw an array of objects including a referent for a ‘known word’. On the other half, the array included an object perceptually similar to the referent of the known word, but which itself was not an appropriate referent (e.g. an apple instead of an orange). Though the children demonstrated an understanding of the known word, they also overextended that word to the inappropriate referent. Mechanisms for such overextensions are discussed, as is the general relationship between comprehension and production.
