Target behaviour is termed as the behavior which is being identified to change the behaviour which is prescribed.
The behaviour can be identified by topography or by function.

1. Agressive- the act of anger which is unplanned tends to hurt something or someone.
2. Assertive.
3. Passive.
4. Passive-aggressive.
