23名学龄期语言障碍儿童和46名正常儿童参加了2项听觉词汇判断任务。语音不透明的影响（即，重音和元音变化（涉及从基本词形成派生词）对词识别的影响。在一项任务中，儿童对语音上透明的真实的派生词（例如，无帽）和伪衍生物（例如，* quickless）。在这项任务中，LI的儿童相比，他们的实足年龄（CA）的同龄人只有微妙的赤字。在另一项任务中，儿童对语音上不透明的真实的派生词（例如，酸度）和伪衍生物（例如，*以及透明衍生物。在这项任务中，LI儿童在识别语音不透明的真实的衍生物方面的准确性大大低于CA儿童，并且比CA和语言年龄（LA）儿童的识别速度要慢。LI和LA组的儿童比CA组的儿童识别语音不透明的伪派生词的速度慢。这些结果被解释在有限的处理能力帐户的语言障碍。
Twenty-three school-age children with language impairments (LI) and 46 typically achieving children participated in 2 auditory lexical decision tasks. Effects of phonological opacity (i.e., stress and vowel changes involved in forming derivatives from a base word) on word recognition were investigated. In one task, children made lexical decisions about phonologically transparent real derivatives (e.g.,hatless) and pseudo derivatives (e.g.,*quickless). In this task, children with LI showed only subtle deficits compared to their chronological-age (CA) peers. In the other task, children made lexical decisions about phonologically opaque real derivatives (e.g.,acidity) and pseudo derivatives (e.g.,*combinity) as well as transparent derivatives. In this task, children with LI were substantially less accurate than were CA children in identifying phonologically opaque real derivatives and were slower to do so than both CA and language-age (LA) children. Children in the LI and LA groups were slower than children in the CA group to identify phonologically opaque pseudo derivatives. These results are interpreted within a limited processing capacity account of language impairment.
