A dynamic interaction model of topic interest and written language fluency: an empirical study

Area of Science:

• Applied Linguistics
• Psycholinguistics
• Second Language Acquisition

Background:

• Understanding the dynamic interplay between affective factors and L2 writing proficiency is crucial.
• Dynamic Systems Theory (CDST) offers a framework for examining evolving relationships in language learning.

Purpose of the Study:

• To investigate the dynamic interaction between topic interest and written language fluency in first-year Chinese university students learning Spanish.
• To analyze the evolving relationship between topic interest and both lexical and syntactic fluency indicators over time.

Main Methods:

• Employed the moving correlation coefficient method to analyze the temporal dynamics of topic interest and fluency.
• Utilized a four-component analytical framework: regression smoothing, correlation distribution analysis, fluctuation curve examination, and change point detection.
• Analyzed 18 essays per participant to capture developmental trends.

Main Results:

• The influence of topic interest on L2 writing fluency is stage-dependent, exhibiting both positive and negative correlations.
• High topic interest does not always guarantee fluent writing; lexical and syntactic fluency subsystems show differential responses.
• Lexical fluency generally correlated positively with topic interest, whereas syntactic fluency showed negative correlations, indicating uneven resource allocation.

Conclusions:

• Affective factors like topic interest exert a nonlinear and multifaceted influence on L2 writing development.
• Pedagogical strategies should focus on enhancing student engagement with topics and balancing attention between lexical and syntactic aspects of writing.
• Findings contribute to CDST-based research in applied linguistics and psycholinguistics regarding L2 writing.
