Abstract
Although the concept of task and its role has been a matter of much controversy in the field of second language acquisition (SLA), there is a general agreement that in language learning, task complexity is required for the effectiveness of the final performance of tasks, (Robinson, 2011). This paper is an overview of the task based language teaching, task complexity, its definition and its importance in language education to gain more insights into this area and its effect on second language (L2) development. Robinson (2001, p. 29) defines task complexity as “the result of attentional, memory, reasoning, and other information processing demands imposed by the structure of the task on the language learner.” Our goal is to gain further insights into this area of second language acquisition (SLA) research by understanding how task complexity works and the effects it has on L2 acquisition.

Summary
The influence of task complexity on the final performance of tasks is regarded important. According to Robinson (2001b), “task complexity is the result of attentional, memory, and other information processing demands imposed by the structure of the task on the language learner “(p.29). Three issues are predicted by cognition hypothesis as the result of increasing the cognitive demands Based on this hypothesis learners will be pushed to achieve to a higher level of accuracy and complexity in L2 production that will result in greater level of communication .Second, interaction and attention to input will be increased. According to Wang (2008), Task-based language teaching (TBLT) is regarded as one of the most important methods in second language teaching He wants to discuss the influence of Planning on the task performance of learners. In conclusion the results of their study revealed that form-oriented activities like tasks in the laboratory can present a suitable pattern for promotion of interaction in language classrooms
