Abstract
Narrative production draws upon linguistic, cognitive and pragmatic skills, and is subject to substantial individual differences. This study aimed to characterise the development of narrative production in late childhood and to assess whether children’s cumulative experience of reading fiction is associated with individual differences in narrative language skills. One-hundred-and-twenty-five 9- to 12-year-old children told a story from a wordless picture book, and their narratives were coded for syntactic, semantic and discourse-pragmatic features. The grammatical complexity and propositional content of children’s narratives increased with age between 9 and 12 years, while narrative cohesion, coherence and use of mental state terms were stable across the age range. Measures of fiction reading experience were positively correlated with several indices of narrative production quality and predicted unique variance in narrative macrostructure after controlling for individual differences in vocabulary knowledge, word reading accuracy and theory of mind. These findings are discussed in terms of the continued importance of ‘book language’ as part of the language input beyond early childhood.
Introduction
The ability to construct narratives, both fictional and factual, is a key aspect of oral language competence. Across cultures stories are told to construct, share and make sense of human experience; narrative language is fundamental both to social interaction and academic achievement, particularly literacy outcomes (Britton & Pellegrini, 1990; Suggate et al., 2018). The development of narrative production skills in early childhood has been extensively studied from an emergent literacy perspective (e.g. Gardner-Neblett & Iruka, 2015) and in relation to language pathology (e.g. Pearce et al., 2010). Less work has focused on narrative production in late childhood and adolescence, a period of steady development of pragmatic language and social cognition (Nippold, 2000). The current study examines linguistic, semantic and pragmatic features of picture-book elicited oral narratives produced by 9- to 12-year-old children. Since children within this age range vary widely in how much they read for pleasure (Nippold et al., 2005), we also assess whether children with more cumulative experience of reading narrative fiction show advantages in narrative competence.
Story construction entails the integration of multiple sources of knowledge into a hierarchical conceptual structure at the discourse level; this complex representation can be conceived as the ‘message’ which, according to standard models of language production, activates grammatical and phonological encoding subsystems to produce a spoken output (e.g. Bock & Levelt, 1994). The types of knowledge that may be activated in the formulation of a conceptual representation of narratives include background knowledge about the world (e.g. cause-and-effect relations, event schemas, protagonists’ goal-oriented behaviours) and knowledge of narrative conventions (e.g. ‘story grammar’; Mandler & Johnson, 1977). The conceptual message comprises features of intended meaning and is assumed to influence the language produced at the sentence level (e.g. through processes of lexical selection and function assignment; Bock & Levelt, 1994) and across sentences (e.g. use of linguistic cohesion devices; Karmiloff-Smith, 1985). Empirical studies suggest that adolescents and young adults produce more syntactically complex language when retelling a narrative in comparison to during a general conversation (Nippold et al., 2014, 2017). One possible explanation for this finding is that stories often contain abstract concepts, which stimulate the use of lower frequency words and more complex syntax. The study of narrative production thus affords a unique window on complex language in action.
Narrative quality has been measured along dimensions relating to aspects of the observed linguistic output (microstructure) and inferred conceptual representation of the story (macrostructure) (Heilmann et al., 2010; Norbury & Bishop, 2003). Measures of linguistic cohesion, structural coherence and references to characters’ mental states correlate with untrained judges’ ratings of narratives, suggesting that these discourse-level features are important indicators of story quality above and beyond the language output at the word or sentence level (Schneider & Winship, 2002). Developmental studies show that the foundations for these discourse-level competences are largely in place by middle childhood, with a clear shift in the length and sophistication of narratives produced between the ages of 5 and 9 years (Berman, 1988; Nicolopoulou & Richner, 2007). In a large study of narratives elicited from children and adults using the wordless picture book
Foundational language skills at the word and sentence level are a necessary prerequisite for narrative production; the quality of children’s narratives has been linked with performance on standardised measures of vocabulary and grammatical knowledge in monolingual, bilingual and clinical samples (Manolitsi & Botting, 2011; Sénéchal et al., 2008; Uccelli & Páez, 2007). Narrative competence is also closely related to literacy skills; longitudinal evidence indicates that the association between oral narrative and reading skills increases in strength during the first three years of reading instruction at school (Reese et al., 2010). Narrative competence may also depend on individual differences in social cognition. A well-developed story integrates the ‘landscape of action’ (events within the framework of the plot) with the ‘landscape of consciousness’ (protagonists’ motivations underpinning these events), such that the explicit plot is given meaning by the inner worlds of the characters (Bruner, 1986). In a study with preschoolers, the extent to which children were able to integrate mental state information with action in a story retelling task was positively related to performance on standard false belief tasks (Riggio & Cassidy, 2009). Theory of mind skills may therefore be an additional source of variation in the comprehension and production of narrative, beyond language and literacy measures (Dore et al., 2018).
Few studies have examined the relation between experiential factors and the development of narrative skills. However, there is reason to expect that children who frequently read fictional texts may produce narratives characterised by more sophisticated linguistic, semantic and/or pragmatic characteristics. ‘Book language’ is an important part of the linguistic input from infancy onwards, as young children experience stories through shared reading interactions and later may read complex texts independently. Book language is differentiated from spoken communicative language input in that it contains greater diversity of word types and more complex sentence structures (Montag et al., 2015; Montag & MacDonald, 2015). Children’s storybooks also contain frequent references to characters’ mental states (Dyer et al., 2000). Book reading provides a rich opportunity for learning, because knowledge about the world, including people’s behaviour and motivations, is conveyed through decontextualised language (Seidenberg & MacDonald, 2018).
There is substantial evidence to suggest that individuals with more experience of text have better language skills and that this association grows stronger through development, likely reflecting a reciprocal causal relation (Cain & Oakhill, 2011; Mol & Bus, 2011). A body of experimental work indicates that children and adults can learn phonological, orthographic and semantic information about new words through incidental exposure during reading (Henderson et al., 2015; Horst et al., 2011). Reading experience has also been linked with sentence-level language production; for example, Montag and MacDonald (2015) reported that 8- and 12-year-old children and adults with more cumulative text exposure produced more low frequency sentence structures (passive relative clauses) in a picture-description task. In a large, longitudinal Finnish sample, children’s recreational reading in the early years of primary education was predicted by their reading skills; by secondary school, more frequent reading for pleasure was an independent longitudinal predictor of reading comprehension, and this effect was specific to book reading over reading of other materials (Torppa et al., 2020). By late childhood, therefore, reading for pleasure may have a specific role in facilitating the development of advanced language skills.
A smaller amount of research has focused on the association between reading experience and social cognition. In a study with 4- to 6-year-old children, Mar et al. (2010) reported that exposure to narrative via storybooks and films predicted variation in theory of mind performance after controlling for vocabulary. Cross-sectional correlational designs cannot establish causality; however, one potential explanation for this link early in development is that shared storybook reading provides a context in which parents often direct children’s attention towards characters’ mental states and alternative perspectives (Ziv et al., 2013). Indeed, longitudinal studies show that parents’ references to cognitive states during interactions with their young children, both in shared storybook reading and other interactional contexts, predict children’s later theory of mind understanding (Adrián et al., 2007; Ensor et al., 2014). When children achieve a sufficient level of reading fluency, experience of reading fiction independently may afford a simulation of the social world, in which they practise reasoning about mental states to explain and predict characters’ actions (Oatley, 2016).
It is therefore plausible that any association between children’s cumulative experience of reading fiction books and their narrative production skills may be explained by vocabulary, reading skills and/or theory of mind. Studies that have directly related reading experience to narrative skills have yielded mixed results. Shared reading experience showed no correlation with the linguistic complexity, cohesion or coherence of 4-year-old children’s oral narratives (Sénéchal et al., 2008). However, a child-report measure of reading for pleasure was a unique predictor of structural coherence and adherence to conventions in written narratives produced by Grade 4 children (Sénéchal et al., 2018). It may be that cumulative experience of fictional plots over a period of years enhances the quality of representations of story elements such as common plot devices and characters’ mental states only by later childhood. Another possible explanation for inconsistent findings is the different measures of shared or independent reading experience used across studies, which include parent-report and child self-report questionnaires, diary records, and author/title recognition checklists completed by parents and/or children. In a study with Chinese preschoolers, Zhang et al. (2018) reported a three-factor structure to a range of measures tapping children’s exposure to books: parent-report measures of shared reading frequency, measures tapping the accessibility of books in the home, and children’s own knowledge of book titles. While all three factors predicted a small amount of unique variance in vocabulary breadth, only children’s knowledge of book titles uniquely predicted vocabulary depth. Triangulating data from different measures, and including instruments completed by children rather than parents, is therefore indicated for studies seeking to investigate children’s cumulative reading experience over time.
Given the limited research on narrative production in later childhood, the first aim of the current study was to explore the development of narrative production between the ages of 9 and 12 years; we expected that narratives produced by older children would be more linguistically complex, semantically rich, cohesive and coherent than those of younger children (Berman, 2008; Berman & Slobin, 1994). The second aim of the study was to examine the association between children’s cumulative experience of fictional texts and their narrative production skills. The association between book exposure and narrative skills has primarily been investigated in early childhood; by late childhood, children vary widely in the extent to which they engage in reading independently (Nippold et al., 2005). We asked (a) which aspects of narrative production are related to children’s cumulative experience of reading fictional texts, and (b) whether associations between fiction reading experience and narrative production skills are explained by individual differences in vocabulary knowledge, reading skills and theory of mind.
Method
Participants
Data were collected during the first phase of a longitudinal study of children’s reading experience and developing language, literacy and socio-cognitive skills. Ethical approval for the study was obtained from York St John University Ethics Committee. One-hundred-and-twenty-six children aged between 9 and 12 years were recruited to the broader study via local schools and advertisements placed in family magazines and websites. One child did not wish to complete the narrative task; therefore, data were available for 125 children (51.2% girls) with a mean age of 10 years 7 months. The large majority of participating children were white British (

Measures and procedures
Narrative production task and coding procedures
Narratives were elicited from children using the wordless picture book
First, children were shown each illustration in turn by the tester and asked to study each one for a few seconds. Next, testers asked children to tell the story in as much detail as possible, turning the pages in their own time. Narratives were audio-recorded and transcribed verbatim. For the purpose of analysis, direct repetitions, reformulations and comments that did not relate directly to the story were removed. Transcripts were segmented into communication units (C-units), defined as an independent clause and its modifiers (Loban, 1976).
The narrative transcripts were coded for seven variables tapping the complexity of language produced, semantic and discourse-pragmatic characteristics. A second rater coded 30% of the sample and inter-rater reliability was assessed by computing intraclass correlations. All variables showed very good inter-rater reliability (see Table 2 for intraclass correlation coefficients).

MLU was calculated as the mean number of words per C-unit.
b. Proportion of complex C-units
Each C-unit was coded as simple or complex (Norbury et al., 2014). A complex C-unit was defined as any utterance containing a main clause and at least one dependent clause, and therefore included relative clauses (
c. Propositional content

d. Linguistic cohesion
An adapted version of Cain’s (2003) procedure for coding inter-clausal connectives was used as an indicator of narrative cohesion. Connectives were coded for whether they expressed a dependent relation between two propositions, including temporal relations (e.g.
e. Structural coherence
The coherence scale used with the same picture book in Reilly et al.’s (2004) study was adapted to capture variation in the extent to which narratives were structured around the story’s central theme. Points were awarded for explicit references to the initiating event (2 possible points), searching theme (7 points) and outcome of each search episode including resolution (7 points), giving a maximum possible score of 16 (see online Appendix for full coding scheme).
f. Mental state references
The number of explicit references to characters’ mental states in each narrative was tallied. Mental state references could include cognitive states (e.g.
g. False belief episode
The ‘Deer Scene’ coding scheme reported by Manhardt and Rescorla (2002) was used to rate children’s reporting of false belief. In this scene, conveyed in two illustrations, the boy grabs onto what look like branches of a tree. However, the branches are revealed to be the antlers of a stag, which lifts the boy onto its head and runs away. Children’s descriptions of this episode were rated on a 4-point scale differentiating the extent to which the boy’s false belief was explicitly described (see Appendix).
Experience of reading fiction
Children’s experience of reading fiction was measured using three instruments:
a. Book recognition test (BRT)
This measure was developed as an indirect test of fiction book exposure that could be completed by children without the need to read text (Zhang et al., 2018). Twenty key illustrations from fiction books aimed at readers between 9 and 12 years old were compiled. Titles were selected by extracting the most commonly occurring books from several children’s bestseller lists and a list of the most frequently borrowed books aimed at the target age bracket provided by a local library. The final list contained both classic titles (e.g.
b. Author recognition test (ART)
Names of 24 authors of fiction aimed at 9- to 12-year-old readers (e.g.
c. Self-reported fiction reading habits
Two items from a child-report Reading Habits Questionnaire were included: (i) children were asked to rate how often they read fiction texts on a 5-point Likert scale ranging from 0 (never) to 4 (almost every day); (ii) children were asked to rate how much they enjoy reading for fun on a 5-point Likert scale range from 0 (I don’t enjoy reading at all) to 4 (I enjoy reading very much).
Language and cognitive measures
Children’s
After a full explanation of the purpose of the study and an opportunity for parents and children to ask questions of the researchers, children provided verbal assent and parents/carers written consent for children’s participation. Children took part in a single testing session with a trained research assistant; testing took place in the university laboratory, family home or school, according to parental preference and lasted approximately one hour. At the end of the testing session, children were given a gift voucher as a token reward for participation.
Results
The development of narrative production skills during late childhood
Descriptive statistics for the seven measures of narrative production are presented in Table 3, alongside tests of difference comparing the narrative performance of 9- to 10-year-olds with 11- to 12-year-olds. Older children’s narratives were more grammatically complex (as measured by MLU and proportion of complex C-units) and contained more propositional content than those of younger children; these age differences remained significant when vocabulary, word reading and theory of mind were controlled. Age effects were not observed in narrative cohesion, coherence, use of mental state terms or false belief narration. It is notable that only 20% of the sample explicitly mentioned the boy’s false belief during the Deer Scene (level 4 of Manhardt & Rescorla’s coding scheme; see Appendix).

The narrative measures were generally moderately to strongly inter-correlated (Table 4), although the measures of coherence and false belief narration were less robustly associated with the other variables. Correlations remained highly comparable in strength when children’s age was partialled out, indicating that associations were not explained by maturation.

To reduce the narrative production data for further analyses, standardised narrative variables were subjected to factor analysis. Because it was expected that factors would be correlated, since all measures were derived from the same storytelling episode, principal components analysis with oblimin extraction was utilised. The resulting model yielded a two-factor solution explaining 63% of the variance (Kaiser–Meyer–Olkin = .76; Bartlett’s χ2(21) = 351.51,

To test whether experience of reading fiction predicts variance in children’s narrative production skills two hierarchical regression models were assessed, differing in the dependent variable (narrative microstructure or macrostructure). At the first step in both models, child age and maternal education were entered as control variables. At the second step, three cognitive-linguistic predictor variables were entered into the models (receptive vocabulary, word reading and theory of mind). Finally, at the third step the composite score of children’s fiction reading experience was entered. The regression models are summarised in Table 7.

Discussion
In this study, we aimed to characterise individual differences in the quality of oral narratives produced by typically developing 9- to 12-year-old children along a number of dimensions relating to linguistic, semantic and pragmatic features. Our second aim was to establish whether children who read more fictional texts for pleasure produce more sophisticated narratives and, if so, whether this relation can be explained by individual differences in vocabulary knowledge, reading ability and/or theory of mind.
We predicted that linguistic, semantic and discourse features of narratives would increase in complexity between the ages of 9 and 12 years. In partial support of this hypothesis, the linguistic quality of narratives showed development within this age range, with older children producing a higher proportion of grammatically complex utterances than younger children. Older children also extracted more of the propositional content of the story from the picture book illustrations and thus produced semantically richer narratives. However, the discourse-level narrative characteristics observed in the current study (linguistic cohesion, structural coherence and use of mental state terms) did not increase in sophistication within the age range studied. Previous research has demonstrated that later language development is marked by gradual increase in the use of more complex syntactic structures, such as embedded relative clauses and past perfect marking (Colletta et al., 2010; Nippold, 2004). However, when narrating a cartoon, the inclusion of narrative clauses (i.e. recounting an observed event) peaked in 10-year-old children and declined in adults; conversely, explanatory and interpretative clauses increased somewhat between 6 and 10 years, but were used most frequently by adults (Colletta et al., 2010). Taken together with previous studies, the current findings suggest that the use of syntactically complex language and inclusion of narrative detail gradually increases through late childhood. In contrast, discourse-level or evaluative features are less subject to age-related change in this developmental period. However, the developmental window investigated in the current study is relatively small; it may be that discourse-level features depend on social cognition, which shows rapid development through adolescence (Sun & Nippold, 2012).
While all seven measures of narrative quality were inter-correlated, principal components analysis indicated a two-factor structure to the data. The first factor was defined by mean length of utterance, syntactic complexity, linguistic cohesion and references to characters’ mental states, and is interpreted to reflect the microstructure of the narratives. Cohesive devices signal narrative structure by establishing links between sentences and clauses. However, the effective use of inter-clausal connectives to maintain narrative cohesion depends on syntactic skills, since inter-clausal connectives are used to combine clauses into more complex sentence structures. The measure of cohesion employed in the current study was more strongly related to indices of the quality of linguistic output (e.g. MLU) than to measures of discourse-level narrative quality (e.g. coherence). Similarly, use of mental state terms during narrative production is often conceptualised as an evaluative device (e.g. Bamberg & Damrad-Frye, 1991) reflecting the conceptual representation of the story. In the current study, the use of mental state terms was more closely related to indices of observed linguistic quality than inferred conceptual representation: children who used more mental state terms also produced more syntactically complex and cohesive narratives. Mental state terms typically consist of adjectives (
A second factor was defined by propositional content, structural coherence and false belief narration and is interpreted to reflect narrative macrostructure. In order to score highly in these measures, children need to construct a rich mental model of the story from the sequence of illustrations and judge which information should be included in the spoken output for the listener to make sense of the story. Of all the propositions indicated by the illustrations of
The second aim of the study was to assess whether children who have more experience of reading fictional texts produce more sophisticated narratives. Both a composite score indexing fiction reading experience and individual recognition checklist and self-report measures were positively correlated with most individual indices of narrative quality. However, fiction reading experience was a unique predictor of the macrostructure, but not microstructure, of children’s narratives, once linguistic and cognitive predictors were controlled. In line with previous studies (e.g. Cain & Oakhill, 2011; Cunningham & Stanovich, 1997), our measure of reading experience showed robust correlations with standardised measures of children’s vocabulary and word reading ability. Congruent with a smaller literature on the relation between reading habits and theory of mind (e.g. Mar et al., 2010), children who had more experience of reading fiction also scored more highly on the Strange Stories test. However, the association between children’s fiction reading experience and the macrostructure of their spoken narratives was not explained by vocabulary, word reading or theory of mind. Reading fiction provides a context for children to learn about propositional concepts typical to narratives (e.g. characters’ behaviours underpinned by false beliefs). Children with more exposure to fictional texts may therefore have access to richer conceptual representations to underpin story construction, whether in spoken form as in the current study or written form (Sénéchal et al., 2018).
The link between narrative language and literacy development has been widely documented in the literature (Dickinson & McCabe, 2001; Suggate et al., 2018). Storytelling recruits children’s syntactic, semantic and pragmatic language skills, as well as knowledge of narrative conventions and background knowledge. There is evidence of the impact of literacy experiences on the emergence of these narrative skills early in development (e.g. Lever & Sénéchal, 2011). Our findings suggest that substantial individual differences in narrative production persist into late childhood and remain linked to literacy experience. While strong causal interpretation of these cross-sectional data is unwarranted, the fact that the association between fiction reading experience and narrative production was not explained by individual differences in children’s vocabulary, reading and theory of mind skills is consistent with the hypothesis that exposure to book language has a role in supporting discourse-level comprehension and production once children have achieved fluent reading (Sénéchal et al., 2018; Torppa et al., 2020). There is evidence to suggest that reading for pleasure tends to decline between late childhood and adolescence, in part displaced by other leisure activities (Nippold et al., 2005; Sullivan & Brown, 2015). Given the importance of book reading for language, literacy and broader educational attainment, fostering children’s motivation to read independently through the transition to secondary school and beyond is of concern to teachers, parents and speech and language therapists working with older children. Factors identified as important in promoting reading for pleasure in young people include access to resources, choice of reading material and positive relationships with teachers, although the evidence base for interventions targeting reading for pleasure is currently limited (Department for Education, 2012).
The amount of variance in narrative microstructure and macrostructure explained by the variables included in this study was small (12–15%), suggesting that other factors influence the production of narratives in this age group. For example, the ability to produce extended decontextualised narratives depends on sentence-level and discourse-level language skills; the standardised measure of receptive vocabulary in this study captured only word-level knowledge. Previous research indicates that children’s narrative skills may also be supported by higher-level cognitive factors including executive function (Friend & Bates, 2014), metacognition (Lepola et al., 2020) and imagination (Trionfi & Reese, 2009).
This study has several limitations. First, structural coherence was not robustly related to other narrative production measures and loaded weakly onto a ‘narrative macrostructure’ factor. This may be explained by the fact that the story structure of
This study explored individual differences in narrative production from a wordless picture book in a sample of 9- to 12-year-old children. Age effects were observed in the linguistic complexity and propositional content of children’s narratives, but not in narrative cohesion, coherence or use of mental state words, during late childhood. The macrostructure, but not microstructure, of children’s narratives was predicted by cumulative experience of reading fictional texts. The role of input and experiential factors in the development of high-level language skills such as narrative production would be clarified by longitudinal studies.
