This study investigates linguistic coordination in fictional dialogue, examining whether the phenomenon typically observed in natural conversation also appears in imagined exchanges created by authors. We analyse dialogues from ten English novels by Jane Austen and E. M. Forster using the Project Dialogism Novel Corpus (PDNC) to measure linguistic convergence across nine function word categories from the Linguistic Inquiry and Word Count (LIWC) lexicon, complemented by network based measures that capture how linguistic adaptation shapes interactions among characters. The results provide evidence of convergence in both authors, confirming that linguistic coordination extends to literary dialogue. The network analysis supports these findings, revealing that alignment is generally reciprocal, unevenly distributed but widespread, and often crosses social and narrative boundaries. Taken together, these results suggest that linguistic coordination in fiction does not depend on deliberate stylistic planning, but reflects underlying cognitive mechanisms involved in language processing and social interaction.

The present article investigates semantic change in psychology-related concepts, in scientific and social media texts comparatively. We assess patterns of change over 15 years (2010-2025) and compare word usage in a corpus of Psychology journals abstracts and Reddit comments, testing whether specialized communities on social media align with psychology experts. We analyze semantic breadth, semantic displacement and neighbours similarity evolutions, and in addition include in our experiments contextual embeddings alongside static Word2Vec embeddings. Our results reveal diverse patterns of semantic change across the examined concepts and confirm that many terms are used differently on social media compared to specialized literature. Furthermore, Reddit communities focused on psychology discussions occupy an intermediate position, adopting a more objective stance than general-domain threads while remaining distinct from specialized literature.
