This is a project to study information that speakers convey by exploiting pragmatic inferences. To understand what people say, one listens both to what is said and what is "unsaid". If there is a plate of 5 cookies on the table and a child eats them all and then tells her sister who made them, "I ate some of the cookies." the child is not strictly speaking lying. Notice that if one eats all of the cookies on a plate, it is also true that one has eaten some of the cookies on that plate. This "some, and possibly all" interpretation is given by the logic of what is said, while the "some, but not all" interpretation is considered to be a part of meaning that is unsaid and is appropriate in some contexts, but not others. Understanding when each of these two interpretations is called for is thought to be a question of which part of the mind is being put to use. The part of the mind that is dedicated to language only is thought to be responsible for the "some, and possibly all" interpretation, while higher order reasoning--not specific to language--is thought to be responsible for the "some, but not all" interpretation. When are children able to grasp this relatively subtle difference in language use? If science could find a moment in their mental developmental when they understand one, but not the other, it would constitute evidence of which parts of the mind develop more quickly than others. Further, do children who are known to have severe language problems show evidence of understanding one kind of interpretation and not the other? If so, not only would there be evidence of distinct developmental timelines for distinct parts of the mind, there might also be a way of identifying children with these disorders early so that they could receive therapeutic services to help them learn to cope with their language problem.This study tests a sample of children who speak Spanish as a first language, because the difference between the types of meaning is clearer in Spanish than in many languages, as a result of there being a word with only the "some and possibly all" meaning ("unos") and another word for that can have either meaning ("algunos"). This project will examine what both typically-developing children and children with the developmental language deficit labeled Specific Language Impairment know about these constructions. Preschool-aged children with this language disorder are very likely to receive a dyslexia diagnosis once they reach school age. Consequently, one aim of this study is to identify differences--in terms of their knowledge of this aspect of language--between children who have language problems and those who do not, as a means for diagnosing language problems early in child development.

这是一个研究说话人通过语用推理传达信息的项目。 要理解人们所说的话，一个人既要听所说的话，也要听“未说”的话。如果桌子上有一盘5块饼干，一个孩子把它们都吃了，然后告诉她的姐姐是谁做的，“我吃了一些饼干。“严格来说，这孩子并没有撒谎。请注意，如果一个人吃掉了盘子里的所有饼干，那么他也确实吃掉了盘子里的一些饼干。这种“一些，可能是所有”的解释是由所说的逻辑给出的，而“一些，但不是所有”的解释被认为是未说出来的意义的一部分，在某些情况下是合适的，但在其他情况下不是。理解何时需要这两种解释中的每一种被认为是一个问题，即大脑的哪一部分被使用。大脑中专门用于语言的部分被认为负责“一些，可能是所有”的解释，而高阶推理-不特定于语言-被认为负责“一些，但不是所有”的解释。孩子们什么时候才能领会语言使用中这种相对微妙的差异呢？如果科学能在他们的心智发展中找到一个他们能理解其中一个而不能理解另一个的时刻，那么这就能证明心智的哪些部分比其他部分发展得更快。此外，那些已知有严重语言问题的儿童是否表现出理解一种解释而不是另一种解释的证据？如果是这样的话，不仅有证据表明大脑不同部分有不同的发育时间表，而且可能有一种方法可以早期识别患有这些疾病的儿童，以便他们可以接受治疗服务，帮助他们学习科普他们的语言问题。这是因为西班牙语中的意思类型之间的区别比许多语言都要清楚，因为有一个词只有“一些，可能是所有”的意思（“unos”），而另一个词可以有任何一个意思（“algunos”）。这个项目将研究两个典型的发展中国家的儿童和儿童与发展性语言缺陷标记为特定语言障碍知道这些结构。患有这种语言障碍的学龄前儿童一旦达到学龄，很可能会被诊断为阅读障碍。因此，本研究的目的之一是确定差异-在他们的语言这方面的知识-有语言问题的儿童和那些谁没有，作为一种手段，在儿童发展的早期诊断语言问题。
