Fiche synthèse

1. Objectifs


Intentions :
« The main objective of the present research was to examine the long term association between the properties of maternal utterances at 18, 30 and 36 months and children’s verbal performance and cognitive development at same ages. Within a heterogenous sample composed of adolescent mothers, adult mothers of low SES and adult mothers of middle SES, group differences in the properties of maternal utternances were examined. The correlations between the different forms and functions of maternal speech and their stability across ages were studied. » (p. 176)

2. Méthode



Échantillon/Matériau :
« The sample consisted of 125 mother-child dyads divided into 3 groups: 32 adolescent mothers (aged 14-19 yrs), 54 adult mothers (aged 20-37 yrs) of low socioeconomic status (LSES), and 39 adult mothers (aged 22-37 yrs) of middle socioeconomic status (MSES). » (p.173)

Instruments :
- The Reynell Scales for child’s language development;
- Bayley Scales of Infant Development (Bayley, 1969);
- Speech categories: the category system used fo the present analyses was similar to other systems differentiating utterances on the basis of the mother’s underlying interactional intent (McDonald & Pien, 1982).

3. Résumé


« The research analyzed longitudinally the properties of maternal utterances and their relation with child’s language and cognitive development. The sample consisted of 125 mother-child dyads divided into 3 groups: 32 adolescent mothers (aged 14-19 yrs), 54 adult mothers (aged 20-37 yrs) of low socioeconomic status (LSES), and 39 adult mothers (aged 22-37 yrs) of middle socioeconomic status (MSES). The form and function of each mother’s utterances to her child at 18, 30, and 36 mo of age were evaluated during a free-play session in the laboratory. Results show differences between the 3 groups in the properties of maternal utterances. Adolescent and adult LSES mothers used more utterances that controlled or directed what the child was doing, and fewer utterances that informed or questioned the child. During their second and third year of life, children from the MSES group obtained higher scores than children of adolescent and adult LSES mothers on measures of language and cognitive development. Multiple regression analysis revealed that the forms and functions of maternal utterances were important predictors of child development. In addition, the forms and functions of maternal utterances from 18 to 36 mo explained 45% of the variance in the children’s score on the Stanford-Binet. » (p. 173)
