On the Complexity of Literary and Popular Fiction

Research findings in cognitive literary studies show that lifetime exposure to literary versus popular fiction has a differential association with social cognition processes such as psychological essentialism, attributional complexity, and, particularly, with Theory of Mind. Experimental findings further show that brief exposure to literary, but not popular fiction, boosts performance on Theory of Mind. These results are interpreted as stemming from the greater complexity of the characters and plots of literary fiction; a claim that is consistent with evidence that readers view literary fiction characters as more complex than popular fiction characters. Here we focus on style, and test whether said differential complexity finds a parallel in the language of these two types of fiction. Results of Natural Language Processing analyses on a corpus of literary and popular fiction texts confirm that literary fiction has greater lexical and syntax complexity than popular fiction.
