In psychology, as well as other social and behavioral sciences, aggression refers to behavior between members of the same species that is intended to cause humiliation, pain, or harm. Ferguson and Beaver (2009) defined aggressive behavior as "Behavior which is intended to increase the social dominance of the organism relative to the dominance position of other organisms" . Predatory or defensive behavior between members of different species is not normally considered "aggression." Aggression takes a variety of forms among humans and can be physical, mental, or verbal. Aggression exists on a continuum with what is commonly called assertiveness, although the terms are often used interchangeably among laypeople, e.g. an aggressive salesperson.
