The purpose is to review the trend in ''person-situation controversy''
, and to comment on recent literature and their implications. ''Person
-situation controversy'' is related to whether people do or do not hav
e consistent personality traits. Although the topic is not at all new,
it aroused a great deal of interest since the publication of Mischel'
s (1968) ''personality and assessment''. Here, we began with Mischel's
criticism against the trait approach, then, we discussed two opposite
viewpoints of situationism and interactionism. Situationism is the id
ea that situational variables influence more on the behavior of people
than personality traits, while interactionism is the idea that person
ality traits and situations interact with each other to influence beha
vior. Furthermore, this article focussed on three conceptual issues, s
uch as consistency, prediction, and meaning of traits. Finally, the re
consideration and evaluation of the two viewpoints were presented from
a viewpoint of personality psychology.
