The instrument used in the current study consists of two parts. Part one of the test is the background questionnaire eliciting personal information of the participants. The questions asked in this part represent the following variables: 1) gender, 2) faculty and major, and 3) years of studying English.

Since the participants in the current study were studying in the university level, studying English for at least 12 years was taken into account
