Agression
Agression is a kind of behavior that causes a lot of nuisance to others. This is probably the reason why it is studied thoroughly.There are several theories about the causes for agression:
1. Frustration
This theory, which has a lot of followers nowadays, makes a link between agression and frustration. When a human being notices that his way to a goal is blocked, agression arises. Here, agression arises because the person is frustrated.
2. Circumstances
Certain circumstances can be a reason for agression, like threat, fear, stress, tension etc..
3. Biological circumstances
Some years ago reserachers found out that there was also an biological factor in agression. People who already showed agressive behavior in their youth als showed agressive behavior later. This has something to do with the brain.
