the affective domain (the students` feelings towards speaking using it) and the cognitive domain (the student` knowledge regarding the cognitive nature of the main components of the English language). And in an attempt to view how the research in second language acquisition deal with these two different variables, the researcher found that the focus of research in second language acquisition (SLA) has traditionally been on issues such as language pedagogy (Grammar Translation method, Audio-lingual, etc.), contents of pedagogical instruction, and ways to improve them. Consequently, the implications of researches in this field remained restricted to the learning and teaching of the language itself; that is to say, to the cognitive domain with little attention being paid to the affective variables learners bring with them into language classroom. It was only in late twentieth century, in the 1970s, that the SLA researchers began to study the significant role played by personally and motivational variables in second language acquisition (Shams, 2006).
