THE THREE
CONFLICTING
ELEMENTS OF
PERSONALITY
Add a Footer 43

Instincts
ID
44
2
+
2
+
ID
•Operates pleasure principles
•It consists of all the inherited (i.e., biological)
components of personality present at birth,
including the sex (life) instinct and the
aggressive (death) instinct.
•Personality of the newborn child is all id
Add a Footer
45
2
+
2
+
ID
•The idea that every wishful impulse should be
satisfied immediately, regardless of the
consequences.
• When the id achieves its demands, we
experience pleasure when it is denied we
experience ‘unpleasure’ or tension.
Add a Footer
46
2
+
2
+
ID
•The id engages in primary process thinking,
which is primitive, illogical, irrational, and
fantasy oriented.
•This form of process thinking has no
comprehension of objective reality, and is selfish
and wishful in nature.

Reality
EGO

2
+
2
+
EGO
•Operates reality principles
•Working out realistic ways of satisfying the id’s
demands, often compromising or postponing
satisfaction to avoid negative consequences of
society.
Add a Footer
49
2
+
2
+
EGO
• The ego considers social realities and norms, etiquette
and rules in deciding how to behave.
• If the ego fails in its attempt to use the reality principle,
and anxiety is experienced, unconscious defense
mechanisms are employed, to help ward off unpleasant
feelings (i.e., anxiety) or make good things feel better
for the individual.
Add a Footer
50
2
+
2

EGO
•Freud made the analogy of the id being a horse
while the ego is the rider. The ego is 'like a man
on horseback, who has to hold in check the
superior strength of the horse.‘
(Freud, 1923, p.15)

Morality
SUPEREGO

SUPEREGO
• The superego incorporates the values and
morals of society which are learned from
one's parents and others. It develops
around the age of 3 – 5 during the phallic
stage of psychosexual development.
Add a Footer
53
2
+
2
+
SUPEREGO
•It also has the function of persuading the
ego to turn to moralistic goals rather than
simply realistic ones and to strive for
perfection.
• The superego consists of two systems: The
conscience and the ideal self.
Add a Footer
54
2
+
2
+
SUPEREGO
•The conscience can punish the ego through causing
feelings of guilt. For example, if the ego gives in to
the id's demands, the superego may make the
person feel bad through guilt.
•The ideal self (or ego-ideal) is an imaginary
picture of how you ought to be, and represents
career aspirations, how to treat other people, and
how to behave as a member of society.

WHY DID IT BECOME
A PART OF SCIENCE?
•Science hardliners found out
that its concepts were
philosophical and supernatural
Add a Footer

2
+
2

•Many believed that Freud’s theory had
no scientific basis as no empirical or
experimental data could support it.
•Despite criticisms, he still continued to
work on refining his theory and how it
can be of great help in treating mental
disorders thus it becomes a science

CONCLUSION
These theories have brought
changes to the perspectives and
perceptions of the scientific
community and the public is the
evidence of science and
technology’s link to humanity.
