Assessment of Morphosyntactic Development in European Portuguese-Speaking Children.

Objective: Studies on the late acquisition of morphosyntax in European Portuguese (EP)-speaking children are relatively scarce in the literature. The purpose of this paper is to report data on the morphosyntactic domain from typically developing children. The present investigation focused on differences in morphosyntactic performance according to specific demographic variables (e.g., gender, age, ecological setting, and socioeconomic background). Patients and Methods: Eighty EP-speaking children aged between 6 years and 6 years and 11 months were assessed with the Language Test - Preschool Language Assessment (TL-ALPE). Results: Within the age range considered, some receptive and productive competencies were acquired. Significant differences were found for gender and age. Conclusion: These outcomes contribute to the knowledge of late developmental processes in the morphosyntactic domain, in EP-speaking children, presenting well-established performance standards. The provided reference information is fundamental to accurately identify children with language impairment and to construct new valid assessment instruments. © 2015 S.
