While many studies have investigated the effect of task complexity on L2 writing, little has been reported on the effects of intended task complexity manipulations on task-generated cognitive demands in L2 writing. This study, therefore, was designed to examine the relative effects of task complexity and cognitive demands on students' L2 writing.…

This study explored the effects of increasing the number of elements and the degree of reasoning on second language (L2) writing and also examined the relationship between writing motivational beliefs and anxiety and L2 writing in simple versus complex tasks. Sixty upper-intermediate L2 learners were invited to write simple and complex…

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…

Based on Robinson's (2001a,b, 2003) Cognition Hypothesis and Skehan's (1998) Limited Attentional Capacity Model, this study explored the effects of task complexity on the fluency and lexical complexity of 108 EFL students' argumentative writing. Task complexity was manipulated using three factors: (1) availability of planning time; (2) provision…

Little is known about the effects of various planning and revising conditions on composition quality in experimental or TESOL education research. This study examined the effects of planning conditions (planning, prolonged planning, free writing, and control), subplanning conditions (task-given, task-content-given, and…
