This study explored the interplay between complexity and accuracy in L2 speech, focusing on the
impact of cognitive load. It investigated how extrinsic and intrinsic cognitive load influenced L2
speech complexity and accuracy. Using three distinct oral tasks with varied complexity, 36
intermediate-to-advanced Japanese learners were tested. Results suggested that under increased
cognitive load, learners strived to maintain syntactic complexity, potentially at the expense of
content words complexity. Interestingly, under high intrinsic cognitive load, there was an
unexpected rise in content words, hinting at different strategies based on cognitive load type.
While extrinsic load allowed retention of function word complexity, intrinsic load saw a decline.
The present study suggests that as cognitive load increased, Japanese learners appeared to
prioritize syntactic complexity. However, their ability to maintain function words complexity
varied based on the type of cognitive load, with increased ability under extrinsic load and reduced
capacity under high intrinsic conditions.
