Different Structural Types of Formulaic Sequences and Oral Fluency: A Follow-up Study

Area of Science:

• Linguistics
• Second Language Acquisition
• Psycholinguistics

Background:

• Previous research on formulaic sequences (FSs) and oral fluency yields conflicting results.
• The processing advantages of FSs may be neutralized or weakened due to unexamined factors.
• Structural differences in FSs might explain their variable impact on oral fluency.

Purpose of the Study:

• To investigate why formulaic sequences (FSs) sometimes fail to enhance oral fluency.
• To examine the role of FS structural types (fixed vs. open-ended) in oral fluency.
• To provide theoretical and pedagogical insights into FS use for language learning.

Main Methods:

• Employed a mixed-methods approach combining quantitative and qualitative analyses.
• Analyzed 120 spoken narratives from language learners.
• Investigated the relationship between FS structural types and oral fluency metrics.

Main Results:

• Fixed FSs significantly impacted speakers' speed and breakdown fluency more than open-ended FSs.
• A higher proportion of fixed FSs correlated positively with speaking speed.
• The variety of open-ended FSs showed a negative correlation with repair fluency; reused or corrected open-ended FSs could impair fluency.

Conclusions:

• The structural type of formulaic sequences is crucial for their effect on oral fluency.
• Open-ended FSs do not consistently enhance speed or breakdown fluency.
• Pedagogical approaches should consider the structural characteristics of FSs to optimize their use in language instruction.
