The study deals with the application of the specificity principle in t
he conceptions of aggression. In many conceptions, the tension between
unitary and specifying approaches to the aggression is evident. The r
elation between the principle of specificity and integration is explor
ed. The author follows these tendencies in the conception based on the
hypothesis of frustration-aggression, in the arousal theory of aggres
sion, in the conception of moral disengagement, and in social-cognitiv
e theories.
