Lexical and phraseological differences between second language written and spoken opinion responses.

Area of Science:

• Linguistics
• Second Language Acquisition
• Corpus Linguistics

Background:

• Understanding modality effects on second language (L2) production is crucial for effective pedagogy.
• Lexical and phraseological complexity are key indicators of L2 proficiency.
• Previous research has explored modality differences, but a detailed analysis of misclassified responses is lacking.

Purpose of the Study:

• To investigate lexical and phraseological complexity differences between L2 written and spoken opinion responses.
• To analyze characteristics of misclassified responses, including learner vocabulary knowledge and rater judgments.
• To explore modality-based variations in L2 linguistic output.

Main Methods:

• Classification analysis of L2 written and spoken opinion responses.
• Examination of lexical and phraseological features.
• Correlation analysis with L2 vocabulary knowledge and rater assessments.

Main Results:

• L2 written responses exhibited significantly higher lexical and phraseological complexity compared to spoken responses.
• Reduced complexity in L2 writing (spoken-to-written boundary) correlated with lower vocabulary knowledge and negative rater judgments.
• Increased complexity in L2 speech (written-to-spoken boundary) was deemed acceptable by raters.

Conclusions:

• Modality significantly impacts lexical and phraseological complexity in L2 opinion generation.
• Learner vocabulary knowledge influences the ability to maintain complexity across modalities.
• Rater perception of L2 use is sensitive to complexity shifts between written and spoken output.
• Promoting modality-insensitive complexity is vital for L2 learners' effective communication.
