The aim of the study is investigation of the specificity of mother - twin’s speech interaction at the age of 4-6 years, features of mother-child interaction due to the order of birth comparison.
The subjects of the study are 4 triads «mother - dizygotic twins» at the age of the children 4-6 years. Mother-child interaction in home conditions was audio and video recorded. Perceptive analysis was used. Audiotests with 184 fragments of interaction for each child and his mother was created. 8 professional experts listened to tests and marked features of mother and child behavior in special questionnaires. Spearmann correleation and multiple regression statistical methods were used to analyse the results.
Mother initiates interaction with both children. When mother refers to a child she spells sounds loud and clearly. First-born children pronounce different types of replicas, such as one word, simple sentences, complex sentences. Second-born children speak by one-word replicas. So mother needs to stimulate him additionally to get an answer: repeats the same question or word, marks her replicas by voice. Mother repeats sounds after the second-born twin to improve his sound articulation. When mother stimulates children to answer all the children interact with mother and answer, but the first-born children demonstrate positive emotions and the second-born children positive or negative emotions.
Correlations between features of maternal and children’s speech are revealed. Differences between maternal speech adressed to the first-born and the second-born twin are presented, such as specificity of their speech.
