Abstract
Narrative ability is an important life-skill and mature narrators do not only provide information about actions and events when telling a story but also include the motivations, emotions and beliefs experienced by protagonists. It is rare for young children to spontaneously explain the beliefs of story characters but the reasons are unclear. In the current study, frog story data from 143 Swedish children aged 4–6 showed that children’s level of explicitness in conveying a fictional false belief was associated with referential narrative ability and use of mental vocabulary, but not to the ability to formulate embedded propositions. Socioeconomic status predicted level of explicitness, whereas no associations were found to age, sex or being multilingual. Future work should examine narrative practices in preschool and in the home more closely, enabling improved support to provide children with equal opportunities.
