This study compared the ability of language learning disabled children and sex/age matched normals to judge the correctness of linguistic stress. Subjects were presented with prerecorded pairs of question-answer trials. In one series they were asked to judge the appropriateness of linguistic stress for each pair. In a second series, they judged semantic appropriateness of the pairs in order to provide a linguistic point of reference for their understanding of the questions. An analysis of variance indicated that the linguistic stress task was more difficult than the semantic interpretation task (p less than .001) and that normal children performed significantly better than LD children on both tasks (p less than .05). Discussion of the data includes interpretation from both perceptual deficit and symbolic deficit perspectives.
本研究比较了语言学习障碍儿童与性别/年龄匹配的正常儿童判断语言重音正确性的能力。向受试者呈现预先录制的问答试验对。在一个系列中，要求他们判断每对试验中语言重音的恰当性。在第二个系列中，他们判断这些对子的语义恰当性，以便为他们理解问题提供一个语言参考点。方差分析表明，语言重音任务比语义解释任务更难（p小于0.001），并且在这两项任务中，正常儿童的表现都明显优于学习障碍儿童（p小于0.05）。对数据的讨论包括从感知缺陷和符号缺陷两个角度进行的解释。
