This study aimed at investigating the relative impact of comprehensible input and comprehensible output on the development of grammatical accuracy and syntactic complexity of Iranian EFL learners’ oral production. Participants were 60 female EFL learners selected from a whole population pool of 80 based on the standard test of IELTS. To investigate the research questions, the participants were ...

Drawing on Robinson’s cognition hypothesis, the study attempted to examine how task conditions influence EFL learners’ oral performance and whether learners’ individual differences in terms of tolerance of ambiguity and self-efficacy mediate the effects of such conditions. To this end, 62 Iranian intermediate EFL learners from private language institutes in Tehran performed four dyadic decision...

The present study investigated the effects of cognitive complexity of pedagogical tasks on the learners’ uptake of salient features in the input. For the purpose of data collection, three versions of a decision-making task (simple, mid, and complex) were employed. Three intact classes (each 20 language learners) were randomly assigned to three groups.  Each group transacted a version of a decis...
