| Abstract: | Relationships between environmental events and aggression are briefly reviewed. Response-independent pain is a fundamental antecedent environmental cause of attack. Aggression-contingent pain decrease causes further attack strengthening, while pain increase following aggression can decrease attack and foster escape and avoidance behavior. Recent experiments that have questioned the pain-aggression relation and proposed, in the alternative, a pain-defense relationship are discussed. It is argued that this contradiction results from observational difficulties in naturalistic settings, discordance between field and laboratory terminology, substitution of behavioral taxonomy in the place of functional analysis, incomplete understanding of previous findings, and an absence of essential experimental control observations. |
