Main premises standing behind the science of psychology are an explanation and differentiation between a normal and abnormal behaviour. The way how a society perceived and described the abnormal behaviour has been evaluating throughout the years. Although, these days, two of the most popular models deserve a particular attention. The first one called the biological approach, believes that the abnormal behaviour has its source in a physical difficulties. Second one, the behaviourist approach assumes that the abnormal behaviour depends on the environmental influence.

The major aim of the biological approach is that, if there is an existence of any physical abnormality, then there is also a possibility of restoring that abnormality by using some kind of a biological treatment.
The focus of this model is based on a combination of the key areas, such as biochemistry, neuroanatomy, microorganisms and genetics.
From the biochemical point of view, abnormality is caused by unbalanced neurotransmitters in the nervous system, e.g. low levels of serotonin have been linked with depression.
Another key area, neuroanatomy, focuses on the functioning of the damaged structure of the brain when abnormal changes occur in person’s behaviour.
Next factor, infection, caused by some bacteria and viruses, has been also linked to disturbances in people’s behaviour.
Also, genetics have been linked to some abnormalities amongst human behaviour, e.g. a person has a 10% chance of developing the…
