The State of Speech Development of Single – and Twin-Born Children – Comparative Analysis

Abstract

This article presents the subject of speech development of twin-born children. Due to the significant importance of environmental and neotological factors, twins are considered to be at risk of developmental disorders. This is manifested by language delay and quantitative and qualitative differences in all aspects of the language, compared to children born from single pregnancies. In this study it was made a comparative analysis of the state of linguistic competences of all language subsystems in the group of single- and twin-born children. The research problem has become the question: do the specific biological and environmental conditions of twin pregnancy determine the dynamics of acquiring the language system by them? The study concerned nine 3-year-old children, including three pairs of twins constituting the research group and three children born from a single
pregnancy constituting the control group.
