There are two main types of Aggression:

Instrumental Aggression and Arousal Aggression

Instrumental Aggression

  • Used to intimidate in situations of crime, such as Robbery and Mugging.
  • Does not require the aggressor to be angry.
  • Therefore they may retain rationality and conscious control of their behaviour.
  • In these situations any factors for High Arousal  may not apply.

 

Arousal Aggression

  • This a behavior which is affected by a state of heightened emotion, principally Fear or Anger, and is part of the body’s biochemical response.
  • This may inhibit the person’s use of the appropriate physical and verbal skills.
  • Arousal Aggression will often result in an escalation in violence.
  • Most forms of Aggression do not just happen “out of the blue”, the slightest gesture or action could turn a threatening situation in to an act of violence.
  • Such gestures/actions are known as “Aggression Triggers”.
