This study examined the relationship of linguistic complexity, captured using a set of lexical richness, syntactic complexity, and discoursal complexity indices, to second language (L2) learners' perception of text difficulty, captured using L2 raters' comparative judgment on text comprehensibility and reading speed. Testing materials were 180…

Frequency is often the only variable considered when researchers or teachers develop vocabulary materials for second language (L2) learners. However, researchers have also found that many other variables affect vocabulary acquisition. In this study, we explored the relationship between L2 vocabulary acquisition and a variety of lexical…

This study investigated the effects of task complexity on child learners' second language (L2) gains, the relationship between aptitude and L2 development, and the extent to which task complexity influences this relationship when recasts are provided. Sixty child EFL learners were assigned to two experimental groups. During the treatment, one…

Addresses the question of whether there are different characteristics and language performance conditions (involving assumed different levels of cognitive demand) associated with different levels of fluency, complexity, or accuracy in test candidate responses. Participants were pre-university students taking English courses. (Author/VWL)

To estimate reading difficulty of items on a sentence repetition task, a study had 50 adult English as a second language (ESL) students repeat each of 26 sentences immediately after two presentations. High-difficulty items were derivationally more complex than low-difficulty items, and the most difficult items involved the processing of…
