The impact of input, input repetition, and task repetition on L2 lexical use and fluency in speaking

The present study investigates the impact of meaningful input on L2 learners’ vocabulary use and their fluency in oral performance (immediate repeat tasks), as well whether effects are mediated by prior knowledge working memory. Ninety university students learning English a foreign language were randomly assigned to one three groups: (N = 29), repetition 32), no-input (i.e., baseline group) 29). group watched videos performing an immediate task, whereas same not only before but also after task. performed tasks without watching videos. groups repeated task two days. Results did show significant effect repetition, input, lexical fluency. However, complexity speech can be predicted receptive memory capacity some extent.
