        In the present study, two different models of task complexity; namely, limited attentional capacity model and cognition hypothesis were examined. To this end, the manipulation of cognitive task complexity along +/- single task dimension on Iranian EFL learners’ production in terms of fluency was explored. Based on the results of the writing test of TOFEL (2004), 48 learners were selected as the participants of the study and were divided into two groups, simple task group (STG, n=24) and complex task group (CTG, n=24). The participants in the STG were given an eight-frame picture which had been arranged in the correct sequence before its administration (+ single task). The participants in the CTG were given all the eight frames which were not arranged in their correct order. These participants were required to order the frames in the right sequence first, before starting writing (- single task). Their output was encoded based on the measure of fluency. One independent sample t-tests was run. The results indicated that the participants significantly generated more words in the complex task. Based on the findings, it can be concluded that in the Iranian context, the predictions of limited attentional capacity model were more accurate. تفاصيل المقالة

        2 - Exploring the Role of Cognitive and Procedural Task Complexity in EFL Learners' Attention to L2 System and Form-focused Self-repairs

        In L2 development, the cognitive complexity of tasks plays a crucial role in task performance and language features produced. However, there have only been few studies addressing the impact of task complexity on EFL learners' attention to L2 system and form-focused self-repairs (FFS).This study explores the role of increasing cognitive task complexity in EFL learners' form-focused attention (FFA) to L2 system (i.e. grammar, lexis, and phonology) and FFS and the effect of increasing procedural task complexity on EFL learners' FFA to L2 system and FFS. The participants comprised one hundred EFL junior students of TEFL. The sample was chosen from the cohort of EFL students at Islamic Azad and state universities in Isfahan and Shahrekod. The participants performed under task conditions of−/+ casual reasoning and −/+ planning time. After each stage, each participant filled in a Likert-type scale to examine his/her attention to different aspects of L2 system .Finally, Wilcoxon Signed Rank Test was used to compare the learners’ instances of of self-repairs at un-increased and increased task complexity occasions. Repeated-Measures ANOVA was used to examine the data. Results showed an overall effect of task complexity on EFL learners' attention to L2 system and FFA behavior across task types. تفاصيل المقالة
