The aim of this study is threefold: Firstly, to describe the acquisition patterns of Greek past tense by children with specific language impairment (SLI); secondly, to investigate the relationship between the phonological salience of past tense in Greek and its acquisition by children of typical and atypical language development; thirdly, to establish an account on the nature of specific language impairment by comparing the acquisition patterns exhibited by children with SLI to those presented by typically developing children. The performance of 10 children with SLI in elicited past tense production is compared to that of chronological age matched (CA) and language matched (LM) controls. Based on the claim that morphophonological salience aids acquisition (or learning), it is predicted that children with SLI will perform better in the production of past forms of higher salience than less salient forms. The results confirm this prediction, providing support for the claim that salience differences do account for better performances in tense marking in Greek SLI.
By reading this article, the reader will be able to: (1) describe the problems children with SLI face in Greek tense marking, (2) explain the reasons why SLI performances differ from one language to the next based on the Interpretability Hypothesis, (3) discuss whether children with SLI differ qualitatively from TD controls in past tense marking and explain how.
本研究有三个目标：其一，描述特定语言障碍（SLI）儿童对希腊语过去时态的习得模式；其二，调查希腊语过去时态的语音显著度与其在典型和非典型语言发展儿童中的习得之间的关系；其三，通过比较SLI儿童与典型发育儿童所展现的习得模式，对特定语言障碍的本质作出解释。将10名患有SLI的儿童在诱发过去时态产出任务中的表现，与按年龄匹配（CA）和按语言匹配（LM）的对照组儿童的表现进行比较。基于形态语音显著度有助于习得（或学习）这一观点，预测患有SLI的儿童在产出显著度较高的过去形式时，会比产出显著度较低的形式表现得更好。结果证实了这一预测，为显著度差异确实能解释希腊语SLI在时态标记方面表现更好这一观点提供了支持。
通过阅读本文，读者将能够：（1）描述患有SLI的儿童在希腊语时态标记中面临的问题，（2）基于可解释性假设解释SLI在不同语言中的表现为何存在差异，（3）讨论患有SLI的儿童在过去时态标记方面与典型发育对照组儿童在性质上是否存在差异，并解释差异情况。
