Assessment of melodic contour of vocalization of infants in second half of the first year
The aim of the research is to compare infants’ vocalizations aged 9–10 months both at family home and the orphans’ home. The research resulted in defining the forms of melodic contour and presenting their classification. 12 types of melodic contours were detected. The research reveals the individual differences between the infants brought up at home and orphans. The orphans` melodic contours are characterized by fewer types (mainly one melodic contour) comparing to the infants` melodic contours who are brought up at home. Significant differences between distributions of different types of melodic contours between the group of family home infants and group of infants from the orphan’s home were not revealed.
