Non-literal language most often permeates interesting and informative narratives. These are the non-perceptible, inferential aspects of a story, such as the explanation of events, the attribution of internal, particularly mental, states to the characters of the story, or the evaluation of events by the participants and/or the narrator. The main aim of this paper is to examine whether non-literal uses can be promoted in 7-year-old French-speaking children's narratives through the use of a short conversational intervention (SCI) which focuses the children's attention on the causes of events. The results show that, after the SCI, the expression of non-literal aspects, even higher-order ones, may make their appearance or significantly increase in children's stories. The reasons for the effectiveness of the SCI in the promotion of nonliteral uses of language and narrative skills in general, as well as the importance of using the SCI as an evaluative instrument, are discussed
