摘要：No concept raises more hackles in second language acquisition circles than consciousness. The role of consciousness in second language acquisition is currently being heatedly debated and should be particularly considered if we are to make progress in understanding how this acquisition takes place. The researchers review the previous empirical studies on the important role of consciousness in second language acquisition (SLA) through stating the views of different authors, philosophers, scholars. Then, the role of consciousness in terms of concepts such as attention, awareness, intentionality, and control comes up for review. These concepts provide growing support for the view that the role of consciousness is vital for second language learning. Finally, it is concluded that conscious awareness of language is necessary if learner wants to use it appropriately. This notion has gained wide support from research findings which state that conscious learning seems to contribute to successful second language acquisition.
