The relations between personality and language use

The authors of this study provided basic descriptive data on the correlation between personality tests and Korean language use. Native Korean-speaking students (N = 80) at Pusan National University completed 2 personality tests, the Myers-Briggs Type Indicator (MBTI; I. B. Myers, M. H. McCaulley, N. L. Quenk, & A. L. Hammer, 1998) and the 5-Factor Inventory (O. P. John, E. M. Donahue, & R. L. Kentle, 1991). They completed a stream-of-consciousness essay, which the authors analyzed using the Korean version of Linguistic Inquiry and Word Count (KLIWC; C. H. Lee, J. Shim, & A. Yoon, 2005). Personality traits were significantly correlated with linguistic variables. Furthermore, the observed correlations between the two types of variables in Korean were consistent with the results of previous LIWC studies conducted in English. The authors discuss language use as a marker of personality.
