Résumé:
The current research seeks to investigate the impact of extraversion/introversion personality
dimension on EFL learners’ test performance. This study aims at displaying the importance of
the personality type of EFL students (particularly extraversion/introversion) during the testing
process. Equally, it endeavors to find out which type is more successful in relation to test
performance; the extrovert or the introvert, while primarily suggesting the supremacy of
introverts. In an attempt to verify the former hypothesis, 101 first year Master students at the
department of English, University of 8 Mai 1945 - Guelma, were subject to an
extraversion/introversion test to uncover their psychological tendencies. Next, a corpus analysis
of exam marks of those previously personality identified students was conducted in order to
count the overall average of extroverts and introverts, separately, for the sake of comparison.
Also, a questionnaire was administered to 19 EFL teachers at the same department; so that to
explore their perceptions towards the subject under study. Unexpectedly, the analysis of both
research tools revealed that extroverts achieve higher grades than introverts. In respect to those
findings, this research significantly contributes to the existing body of knowledge and offers a
bunch of recommendations for future research.
