a review towards input processing theory: dynamic system view

Input is a significant factor in second language acquisition (sla), and without it, the output or the production is not meaningful that is without the input of some sort, the learner cannot communicate effectively. input processing model is proposed by vanpatten, and he explained his model with two main principles. while it is believed that input processing theory is not a very comprehensive model to explain all of the aspects of language acquisition, it can provide a better understanding of acquiring any language in any context. the principles, misunderstandings, claims, and implications are provided. afterward, input processing is viewed from a dynamic system lens, and further details are discussed in the current review paper.
