La morfología flexiva en el trastorno específico del lenguaje y en la deprivación sociocultural

Children with Specific Language Impairment (SLI) and children with Sociocultural Deprivation (SD) have difficulties with Inflectional Morphology. The aim of this study is to show the difficulties with morphology that experience these subjects. Three groups of subjects were selected: one with specific language impairment, one tipically developing children and one with sociocultural deprivation. Two measures of inflectional morphology were used that presented different contextual influences: Real inflectional morphology, with contextual influence and no real inflectional morphology, without contextual influence. Our results show that SLI and SD have difficulties with real inflectional morphology tasks, that are influenced by previous learning. In contrast, only SLI have difficulties with no real inflectional morphology. In this way, SLI have difficulties with the application of morphological rules. Finally, we discuss the practical implications of our results.
