This study aimed at investigating the relationship between two personality types, namely, extroversion vs. introversion, and two types of correction (self-correction and teacher correction) in an EFL writing context. Review of literature revealed that a few studies have been conducted on the efficacy of error correction techniques with regard to different personality traits of the language learners in an EFL context. Moreover, empirical studies that aim at determining the correlation between extroversion and language performance tend to yield inconsistent results. Therefore, an attempt was made in this study to investigate the relationship between self and teacher correction methods with the personality traits of Extraversion/Introversion among Iranian FL students. For this purpose, 48 medical students at Shiraz University of Medical Sciences, Shiraz, Iran, taking the academic writing course, participated in the study. In the beginning, the questionnaire devised by Marie G. Mclntyre (2010) was used to determine their personality types, i.e. extroversion and introversion. Then, the students were assigned into two classes. In one class, self-correction of the assignments was used and teacher correction was used in the other. Then, data were subjected to independent t-test as an indication of inferential statistics. The results showed that there was no statistically significant difference between the two personality types and the two types of correction.
