Temperament as an indicator of language achievement

Language learning is a complex process that is controlled or influenced by a host of linguistic and non-linguistic factors. Some of these factors are the main concerns of psychologists rather than linguists. Ever since psychology began to develop in the 20th century, more and more individual characteristics were identified and defined. Eysenck’s introduction of a way to measure temperament interested (applied) linguists, and some of them tried to investigate the influence of temperament on language learning. The present study, too, set out to investigate the probable effects of temperament on EFL speaking achievement. 139 Iranian intermediate-proficiency university students took the U-test, an IELTS-based structured interview, and the Eysenck Personality Test. They then took a speaking course. Another structured interview was conducted at the end of the course as the post-test. The results of a Mixed between-within Subjects Analysis of Variance (SPANOVA) indicated that introverts were advantaged in speaking achievement. The sanguine participants in the study outperformed the choleric ones who in turn outperformed the melancholic participants. The weakest results belonged to the phlegmatic participant group.
