This chapter defines terms and discusses the consequences of these definitions. There are three sections, one each for aggression, anger, and hostility. These three terms refer to three different aspects of behavior: instrumental response, emotional reaction, and attitude. Aggression is an instrumental response that administers punishment; anger is an emotional reaction with prominent autonomic and skeletal-facial components; hostility is a negative attitude, with attitude defined in terms of implicit verbal responses. Although these three aspects of behavior often cluster together, it is necessary for expositional purposes to treat them separately. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
