This study investigated mothers' notions of appropriate speech to 40 children aged 1; 6 to 3; 6. Spontaneous maternal action-directives were analysed in terms of the explicitness with which they expressed syntactic and lexical clues to action-directive intentions. Cross-sectional and longitudinal changes, and progressions within maternal repetition sequences, indicated that the children perceived as most limited in inferential skills elicited the most restricted input. Most of the action-directives they heard could be interpreted non-inferentially, because syntactic and lexical clues to intentions were explicitly expressed. External supports were removed gradually in response to the mother's perception of her child's increasing ability to draw extra-linguistic inferences. Several theoretical models of non-literal speech-act comprehension are supported. It is argued that the differences in language use reflect the mother's notions of the speech a listener is likely to understand.
