Task variation is an integrative method aiming at the importance of learner-to-learner interactions in a wide range of learning contexts and fostering authentic use of language and meaningful communication. This study investigated the impact of task variation on the accuracy and complexity of Iranian EFL learners’ oral speech. In so doing, 80 intermediate EFL learners, majoring English at the I...

This study examined the effects of cognitive task complexity increase on the complexity, accuracy, and fluency (CAF) as well as the temporal distribution of the cognitive and metacognitive processes involved in computer-mediated L2 written production. To this end, the study employed a between-subjects experimental design with 85 EFL learners from a language learning institute in Iran. Participa...

Task  repetition  is  now  considered  as  an  important  task-based  implementation  variable  which can affect complexity, accuracy, and fluency of L2 speech. However, in order to move towards theorizing  the  role  of  task  repetition  in  second  language  acquisition,  it  is  necessary  that individual variables be taken into account. The present study aimed to investigate the way task r...

The present paper aims to study the effect of skill complexity during different delays on bidirectional transfer on bidirectional transfer of tracking task in different stages (pretest, acquisition phase, immediate transfer, one-day delayed transfer, two-day delayed transfer, and seven-day delayed transfer). Three variables including handedness, time lagges, and skill complexity were studied. T...

research on pre-task planning has revealed that planned conditions have produced more fluent and complex language than unplanned conditions. to date, most of these studies have investigated the effects of individual planning on language production while collaborative planning has received scant attention. to determine the effects of pre-task planning on second language written production, the p...

The shift of emphasis away from written to oral skills has stimulated an incipient concern in second language research to investigate ways of helping second and foreign language learners achieve higher degrees of oral proficiency. Priority solely taken over accuracy, complexity, or fluency of speech might be justifiable with regard to the context in which learning takes place.  Accuracy and com...

background considering the cognitive and linguistic complexity of discourse production, it is expected that individuals with traumatic brain injury (tbi) should face difficulties in this task. therefore, clinical examination of discourse has become a useful tool for studying and assessment of communication skills of people suffering from tbi. among different genres of discourse, persuasive disc...

This study aimed to investigate the impact of task sequencing, along +/- reasoning demands dimension, on writing task performance in terms of accuracy.  The study was motivated by Robinson’s Cognition Hypothesis (CH) as well as previous studies investigating the relationships between task complexity and second language production. The participants of the study were 90 intermediate students at t...
