In this study 160 children, aged 11 years with a definite history of specific language impairment (SLI), completed four tasks that could be potential positive psycholinguistic markers for this impairment: a third person singular task, a past tense task, a nonword repetition task, and a sentence repetition task. This allowed examination of more than one type of marker simultaneously, facilitating both comparisons between markers and also evaluation of combinations of markers in relation to identifying SLI. The study also provided data regarding the markers in relation to nonverbal IQ, made use of new normative data on all tasks, and examined marker accuracy in relation to current language status. The results show that markers vary in accuracy, with sentence repetition (a previously unused marker) proving to be the most useful. This psycholinguistic marker shows high levels of sensitivity (90%), specificity (85%), and overall accuracy (88%), as well as being able to identify the majority of children whose current language status falls in the normal range despite a history of SLI.
在本研究中，160名11岁有特定语言障碍（SLI）明确病史的儿童完成了四项任务，这些任务可能是该障碍潜在的积极心理语言学标志物：第三人称单数任务、过去时态任务、非词重复任务和句子重复任务。这使得能够同时检查不止一种类型的标志物，既便于标志物之间的比较，也便于评估标志物组合在识别SLI方面的作用。该研究还提供了关于标志物与非言语智商关系的数据，利用了所有任务的新常模数据，并检查了标志物相对于当前语言状态的准确性。结果表明，标志物的准确性各不相同，句子重复（一种以前未使用过的标志物）被证明是最有用的。这种心理语言学标志物显示出高水平的敏感性（90%）、特异性（85%）和总体准确性（88%），并且能够识别出大多数尽管有SLI病史但当前语言状态处于正常范围的儿童。
