Abstract
Infant temperament characteristics of activity level, task persistence and affect were measured in an eight-month longitudinal study of eight children. Discourse and pragmatic features of their mothers' speech, specifically total number of utterances and use of self-repetitions, directives and attention-getting devices, were also monitored. Pearson correlation analysis suggested complex interactions between maternal speech and infant temperament. In some cases a maternal speech pattern appears to maintain an infant temperament characteristic. In others, a child characteristic appears to maintain a maternal speech form. The results are used to argue that non-linguistic child behaviours may influence maternal speech and deserve further attention in investigations of the link between maternal speech and child-language development.
