Freud introduced the idea that a part of the ego is unconscious. The ego is that
part of the id which has through perception being modified by the external
world. The id controls our basic biological needs and desires. The ego operates on rationality
and makes decisions on what to do or not to do. Whenever the id has a demand,

between the id and the super ego. The super ego censors and keeps repressed

` 2. Life and death instincts
Life instincts are sometimes referred to as sexual instincts. They are instincts that
deal with survival and reproduction. They are important for sustaining the life of
an individual as well as species. They also include such drives as thirst, hunger and
pain avoidance.
According to Freud, the goal of all life is death. He concluded that people hold an
unconscious will to die but the wish is largely tempered by the life instincts.
According to Freud, self-destructive behavior is an expression of the energy
created by the death instincts. When this energy is directed outward onto others,
it is expressed as aggression and violence.

Freud broke down periods of child development into stages called the
psychosexual stages. The stages are:
Oral 1-2 years
Anal 2-3 years
Phallic 3-5 years
Latency 6-12 years
Genital 13 years and above.
He believed that if one of these stages was not completed correctly, a child would
grow into an adult that was not well adjusted. He emphasized the importance of
the influence of early parent-child relationship on development. He believed that
the parents ability to manage the child??™s sexual and aggressive would have a large
effect on how the child behaved as an adult.

psychological strategies brought into play by the unconscious mind to
manipulate, deny and distort reality through processes such as
repression ,identification and rationalization. Defense mechanism are used when
someone is in a situation that causes anxiety.
5.Conscious and unconscious mind

but also normal behavior of the individual in social institutions. He argued that
dreaming had a key role in psychoanalytic theory. A dream is everybody??™s contact
with the unconscious.
