That we are sensitive to those things that our ancestors would have been prepared for danger that could be dangerous. it also occurs if the person has little or no experience of the situation that they are in.

Observation

A child watches her older brother's behaviour when he finds a spider in the bath.

Reinforcement

When the little girl copies her brothers actions, she is consoled by her mother.

These theories can determine why people would get a phobia without coming into direct contact with the feared object or situation.

Psychoanalytic theory and phobias

id

This contains the sexual and agressive energies that we are born with, these instincts are buried in our unconscious. this desire needs to be satisfied immediatly

ego

starts developing around 3 years old, we begin to realise that we cannot have all of our needs satisfied, but still tries to get it. The role of the ego is to control the urgent demands of the id and the restraints of the superego.

superego

develops around the age of 6, is the moral part of our personality, lives in our unconscious

Psychoanalytic ego relating to phobias

Repression

Is where we force the memories of distress or conflict into our unconscious, where they remain unresolved. for example, the fear of agraphobia (fear of open spaces) may be because the child was left alone as a child. this distress has been repressed.

Displacement

Is where we transfer our negative feelings (such as aggression, jealousy or fear) onto something that will not harm us. for example: a psychoanalytic explanation for xenophobia could be that the individual hated his father so, because he was unable to express this feeling to the father, the fear was displaced to foreigners. the individual feels as if he can express his feelings to foreigners more than he can to his father

Projection

In which unacceptabe feelings are attributed to someone else, ^^ might project his feelings onto foreigners and now sees them as people who are fearful and harmful.

Evaluation of Psycholanalytic theory of phobias

Freud's theory can explain the powerful emotions that people experience with a phobia. This theory can also explain why people can be phobic of objects or situations without direct experience of it.

However, because the conflicts are in the unconscious, it means that it is not possible to be sure that these are the causes of phobias.

It also fails to exlplain why other people who may have been left alone as a child or who hatd there father's have no phobias.
