Abnormal psychology is the study of patterns of behaviour that deviate from the accepted norms of society, but abnormal psychology doesn’t study all deviations. Only those that can be classed as mental disorders.

Basically, we learn violence by observing others.

In short, addiction works in the following way:

You do something that causes your brain to feel dopamine and other neurotransmitters and hormones.
These make you feel amazing.
Then you continue to do the behaviour, so your brain continues to release these neurochemicals.
But over time your brain builds up a tolerance to these neurochemicals.
Meaning that you need to do the behaviour more to get the same effect.
