Abstract—Combination factors of perceptual reasoning and
moral competency may contribute to the significant variance in
explaining the extraversion trait of personality. This paper
determines selected factors (i.e. perceptual reasoning and moral
competency) that potentially predict the extraversion. The
self-administered of Universiti Sains Malaysia Personality
Inventory (USMaP-i) and the Moral Competency Inventory
(MCI) were distributed to 33 undergraduate medical students
studying at Health Campus, Universiti Sains Malaysia. Upon
completion of the questionnaires, a quick simple intelligence
test i.e. Perceptual Reasoning Test from the Wechsler Adult
Intelligence Scale-Fourth edition, was performed. Moral
competency explained 13% of the variance of the extraversion.
Meanwhile, perceptual reasoning did not indicate any
significant prediction towards extraversion. The element of
morality is important to determine extraversion, rather than
intelligence. However, this finding should be accepted with
cautious due to the preliminary analysis and sample size
limitation
