This study investigated the effects of varying degrees of linguistic constraint upon the performance of hard-of-hearing subjects in a repetition task. Experimental stimuli consisted of three sets of sentence strings: grammatical, semantically anomalous, and ungrammatical, respectively. While the control group performed essentially equally across all three conditions, the hard-of-hearing group performed best to the grammatical stimuli and worst to the ungrammatical stimuli. It was hypothesized that the hard-of-hearing subjects employed a primitive sentence dictionary, while the normal-hearing subjects had developed a more sophisticated word dictionary.
本研究调查了不同程度的语言限制对听力障碍受试者在重复任务中的表现的影响。实验刺激由三组句子串组成：分别是符合语法的、语义异常的和不符合语法的。虽然对照组在所有三种条件下的表现基本相同，但听力障碍组在符合语法的刺激下表现最佳，在不符合语法的刺激下表现最差。据推测，听力障碍受试者使用的是原始的句子词典，而听力正常的受试者则发展出了更复杂的单词词典。
