Morphophonological salience as a compensatory means for deficits in the acquisition of past tense in SLI.

Unlabelled: 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.

Learning Outcomes: 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.
