- Abstract
This study compares language and cognitive development of children from different socio-economic backgrounds, during the first three years of their life, in relation to the duration of maternal vocalizations and to the number of toys available to the child in his/her environment. A total of 209 mother-child dyads participated in the study. The sample was divided in three groups of mothers: 65 teenage mothers, 91 mothers of low socioeconomic status (LSES), and 53 mothers, of higher socioeconomic status (HSES). Results showed that children of teenage mothers and children of LSES mothers had a language development (measured with the Reynell) and a cognitive development (measured with the Bayley and Stanford-Binet) inferior to those of children of HSES mothers. The duration of maternal vocalization at 6 and at 18 months of age was related to measures of child development, particularly to child language development at 18 and 24 months. Furthermore, the number of linguistic and social toys in the child's environment was correlated with some measures of language and cognitive development. Variability in children's language and cognitive development is related to environmental factors which seem more significant at certain times than others in the child's development.
