The effects of genres on the development of multifaceted linguistic complexity in Chinese learners of German: A longitudinal corpus analysis.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Genre-based research holds significant theoretical and practical importance in second language acquisition (SLA). While many L2 English writing studies have suggested argumentative writing was generally more challenging than narrative, whether this generalization applies to typologically different languages, such as German with its complex morphological and structural properties, requires further investigation. Specifically, genre effects on L2 writing development remain insufficiently understood for non-English languages, particularly regarding complexities beyond syntactic and lexical. This study examines how genre influences the development of morphological, lexical, syntactic, and cohesive complexity in elementary-intermediate Chinese learners of German over time. A longitudinal corpus of narrative and argumentative essays from 21 learners, who wrote both genres, was analyzed. The results show that genre effects were evident but not straightforward, with no genre consistently exhibiting greater complexity. Over time, learners predominantly exhibited nonlinear development patterns, suggesting the dynamic nature of SLA. Additionally, they exhibited decreasing lexical sophistication in both genres despite improvements in other complexity measures, indicating a "complexity trade-off" between linguistic subsystems. These findings contribute empirical evidence to the cross-linguistic comparisons in SLA research and suggest that curricula should incorporate diverse genres to develop multifaceted linguistic competence, with pedagogical approaches tailored to genre-specific complexity patterns and developmental trajectories.
