The impacts of task characteristics on second language (L2) writing require further exploration. This study examined the effects of increasing task complexity on L2 argumentative writing. Upper-intermediate L2 learners performed two writing tasks with varying degrees of complexity in relation to the number of elements and the degree of reasoning.…

Investigating the effects of task design and implementation features on second language (L2) production is necessary, as the findings can provide potential insights into pedagogical and assessment task design and sequencing as well as into the nature of L2 learners' attentional resources. To this end, this study probed into the effects of task…
