Electrophysiological Evidence for Specific Language Imapirment: A Case Study in Croatian

Recent developments in the SLI related research show a turn towards the search for electrophysiological substrate of the language deficit. The method of measuring the event-related potentials, with its excellent time resolution, proves to be suitable method for this new research orientation. Both pre-linguistic deficits (e.g. sound discrimination) and deficits in the higher-level processing (semantics, syntax) are sought for. In this research we applied three electrophysiological measures to a child with SLI. The measures include a phoneme reconstruction task and stimuli with syntactic and semantic violation in order to obtain the effects in mismatch negativity (MMN), left anterior negativity (LAN), P600 and N400. To define the difference between the SLI and typical language development, a TLD child is tested, as well. The results - having phonological, semantic and syntactic component - could contribute to the long-disputed discussion on the nature of the SLI. Various theories make different predictions: if the deficit is grammatical, no difference in MMN should be present. However, if the deficit is related to the ability to process rapid acoustic stimuli, the MMN effect will be smaller in SLI children. Semantic and syntactic violation experiments could show the difference in higher-level linguistic processing between the SLI child and the controls. The deficits in this domain could be explained by different variables and alongside with different theories on the nature of SLI.
