The document summarizes key aspects of Sigmund Freud's theory of personality and structure of the mind. According to Freud, personality develops from interactions between the id, ego, and superego. The id is unconscious and pleasure-seeking, the ego is conscious and rational, and the superego develops later and concerns morality. Freud also described three levels of consciousness - conscious, preconscious, and unconscious - with most contents being in the unconscious.

1. Functions of brain
• Attention and concentration
• Self-mointoring
• Organization
• Speaking(expressive language)
• Motor planning and initiation
• Awareness of abilities and limitations
• Personality
• Mental flexibility
• Inhibition of behaviour

2. STRUCTURE OF MIND
• According to Freud’s personality theory(1923)
Our personality develops from the interactions
among what he proposed as the three
fundamental structures of the human mind: the
id,ego and superego.

3. STRUCTURE OF MIND
The ID, Ego and Superego
The ID = Unconscious.Pleasure oriented and selfish.Driven by
‘pleasure principle’. Insatiable instincts present from birth.
The Ego = Conscious.Rational,driven by the ‘reality
principle’.Balancesv conflicting demands of the Id and
Superego.
The Superego = Last part of personality to develop.Develops
through socialization.Concerned with morality,right and
wrong.

4. LEVEL OF MIND
Freud divided human conciousness into three
levels of awareness:
 The conscious
 Preconscious
 Unconscious

5. CONSCIOUS
immediate Awareness
Communicates to the outside world and the inner self
through speech,pictures,writing,
physical movement, and thought
Only level of mental life that are directly availble to us
This is seen as the tip of the iceberg.For example, you
may be feeling thirsty at this moment and decide to get a
drink

6. PRECONSCIOUS
• Accesible memories
• It exists just below conscious.The preconscious
Contains thoughts and feelings that a person is not
currently aware of,but which can easily be
brought to conscious.
• If you were asked what you watched last night or
what you had for breakfast in the morning, you
would be pulling that information out of your
preconciousness.

7. UNCONSCIOUS
• It is a resevoir of feelings,thoughts,urges and
memories that outside of our conscious
awareness.
• Most of the contents of the unconscious are
unacceptable or unpleasant, such as feelings
of pain, anxiety or conflict.

8. ALTERED STATE OF CONCIOUSNESS
Altered or abnormal levels of conciousness describe states in which a person either has
decreased cognitive function or cannot be easily aroused.
Confusion=Confusion describes disorientation that makes it difficult to reason,to
provide a medical history, or to paticipate in the medical examination.Causes
include sleep deprivation,fever,medications,alochol intoxication etc.
Delirium=Delirium is a term used to describe an actual confusional state.It is
characterized by impaired cognition.
Lethargy and Somnolence=describe severe drowsiness,listlessness, and apathy
accompanied by reduced alertness.
Stupor=is a level of impaired consciousness in which a person only minimally
responds to vigorous stimulation,such as pinching the toe or shining a light in the
eyes.
Dementia=is used to describe a group of symptoms affecting memory, thinking and
social abilities severely enough to interfere with your daily life.
Coma= is a state of unresponsiveness,even to stimuli.
