- Predatory aggression: attack on prey by a predator.
- Inter-male aggression: competition between males of the same species over access to females, dominance, status etc.
- Fear-induced aggression: aggression associated with attempts to flee from a threat.

[edit] Aggression against outsiders
The easiest aggression to explain is that of a group defending itself against a predator to prevent being eaten.
Either the strong will form a circle around the weak and defend them, thus using aggression and also endangering themselves, or the group will flee and the weak will be eaten.
[edit] Aggression against the own kind
One function of aggression is that the leader of a group is determined or the pecking order.
Another purpose of aggression is the gaining of an own territory. Initially that means scaring away the competition of the own kind. An effect of this is that the own kind will spread itself over the available space, each having its own territory. Once all territory has been used up, the aggression will, instead of scaring away, lead to competition or death to weaker parties.

[edit] Psychology
Aggression is one of the most important and most controversial kinds of motivation. Its use as a category in the psychology of motivation has often been criticised, because it is clear that it encompasses a vast range of phenomena, from modern war to squabbles between individuals. It is far from clear that these have anything in common other than the risk that someone gets hurt. There is a constant danger that concepts and explanations that are useful in the study of one kind of aggression will be misapplied in a different field. However, it remains one of the most important topics in many areas of psychology and other

[edit] Aggressive Behavior in Children
Definition: "Having a combative readiness, driving forceful energy or initiative, having or showing vigor, strength, or firmness" (Webster’s Dictionary, 1998).
What is Typically Expected of Children?
- Young children preparing to enter Kindergarten need to develop the socially important skill of being assertive. Examples of assertiveness include asking others for information, initiating conversation, or being able to respond to peer pressure.
- In contrast, some young children use aggressive behavior, such as hitting or biting, as a form of communication.
- Aggressive behavior can impede learning as a skill deficit, while assertive behavior can facilitate learning.
- By school age, children should learn more socially appropriate forms of communicating such as expressing themselves through verbal or written language; if they have not, this behavior may signify a disability or developmental delay
What Causes Aggressive Behavior in Children?
- Physical fear of others
- Family difficulties
- Learning, neurological, or conduct/behavior disorders
- Emotional trauma
- Exposure to violence on television, film or other media sources.
Summary of Best Practice Recommendations:(1) [American Academy of Pediatrics]; http://www.aap.org: 'Set firm, consistent limits to help children self monitor emotions and behavior; make sure all care takers agree to the same limits. Provide examples of effective and socially acceptable ways of managing anger; be careful not to reinforce aggression with aggressive forms of punishment. Also, model acceptable behavior as a caretaker by managing your own temper. Remember that occasional outbursts are normal. If aggressive behavior continues for more than a few weeks, consult a pediatrician or mental health professional.'
(2) [National Association of School Psychologists; http://nasponline.org] 'Overly aggressive behavior can signify a social skills deficit; direct instruction, modeling, and coaching can help children acquire the skill of assertion, which as a replacement behavior may help prevent aggressive behavior.'
