This paper reports on a focused investigation into the immediate effects of oral narrative task repetition by two adult EFL learners of intermediate and high proficiency. Two participants performed a narrative speaking task after watching a cartoon video clip and repeated their performance three times, followed by a retrospective report in an interview. The results showed that repetition of narrative tasks increased fluency and accuracy, while complexity was the least sensitive to the practice effect. At the same time, it was found that the learners had generally correct self-perception of their performances, which was the interaction of enhanced repeated performance, fatigue, and their proficiency levels.
