Examining reading fluency in a foreign language: Effects of text segmentation on L2 readers

Grouping words into meaningful chunks is a fundamental process for fluent reading. The present study is an attempt to understand the relationship between chunking and second language (L2) reading fluency. The effects of text segmentation on comprehension, rate, and regression in L2 reading were investigated using a self-paced reading task in a moving-window condition. The participants were intermediate and advanced level Japanese EFL learners. The difficulty of chunking a text negatively affected comprehension and smoothness for the intermediate learners, while the advanced learners were able to overcome chunking difficulty. In this study, although the negative effects of chunking difficulty were observed, the positive effects of assisting chunking were not clearly detected, which was interpreted as suggesting that the relationship between chunking and reading needs to be considered in light of the complex interplay between text difficulty and different aspects of reading.
