Personality
Personality is one of the most important topics in psychology because it helps explain why people
think, feel, and behave differently from one another. Every individual has a unique personality that
influences daily behavior, relationships, decision-making, communication, and emotional
responses. Personality develops through a combination of biological factors, learning, social
experiences, and environmental influences.
Psychologists study personality to understand individual differences and patterns of behavior.
Various theories have been developed to explain how personality forms and changes over time. In
this chapter, students will learn about the meaning and characteristics of personality, Freud’s theory
of personality, defense mechanisms, behavioral theory, observational learning, and reinforcement
theory. These concepts help explain how human behavior is shaped by unconscious processes,
learning, and social experiences.
Definition of personality
Personality refers to the unique and relatively stable pattern of thoughts, feelings, and behaviors
that distinguish one individual from another.
Personality influences how people think, behave, react, and interact with others. It develops
through experiences, learning, environment, and social interaction. Personality also explains why
individuals behave differently in similar situations. Some people are confident and sociable, while
others are shy and reserved.
Examples
(a) One student actively answers questions in class, while another student remains silent even
when they know the answer.
(b) In a workplace meeting, one employee confidently presents ideas, while another employee
avoids speaking in front of the group.
Key aspects/characteristics of personality

Personality is unique because every individual is different.

It is relatively stable because personality usually remains consistent over time.

Personality also influences emotions, behavior, communication, and relationships.

Experiences may change some behaviors; major personality traits often remain stable.
Examples
(a) A helpful student regularly assists classmates with assignments, while another student prefers
working alone.
(b) A customer service worker with a friendly personality communicates warmly with customers,
while another worker may appear serious and reserved.
Freud’s Theory of Personality
Freud’s Theory of Personality explains that personality is influenced by unconscious desires,
conflicts, and psychological processes.
Sigmund Freud believed that much human behavior is influenced by unconscious thoughts and
inner conflicts. According to Freud, personality develops through interactions among different
parts of the mind. These parts influence thoughts, emotions, and actions in daily life.
Freud divided personality into three parts:
1. Id
2. Ego
3. Superego
Examples
(a) A student wants to use a mobile phone during class but also knows the teacher may punish
them.
(b) An employee wants to leave work early for personal enjoyment but understands workplace
responsibilities and rules.
(1) Id: The id is the instinctive or natural, and pleasure-seeking part of personality.
The id operates according to the pleasure principle. It seeks immediate satisfaction of desires
and needs without considering rules, morality, or consequences. The id is present from birth
and includes basic drives such as hunger, pleasure, and comfort.
Examples
(a) A student suddenly starts talking loudly during class because they want attention immediately.
(b) An employee spends all their salary immediately on shopping without thinking about future
expenses or savings.
(2) Ego: The ego is the rational and realistic part of personality.
The ego operates according to the reality principle. It balances the desires of the id with social
rules and practical reality. The ego helps individuals make sensible decisions and behave
appropriately.
Examples
(a) A student wants to play games but decides to complete homework first.
(b) A business manager carefully plans company spending instead of making impulsive financial
decisions.
(3) Superego: The superego is the moral and ethical part of personality.
The superego represents social values, morals, and conscience. It guides individuals to behave
correctly and creates feelings of guilt or pride depending on behavior. The superego helps people
distinguish right from wrong.
Examples
(a) A student returns a lost pen to a classmate because they believe stealing is wrong.
(b) An accountant refuses to manipulate financial records because it would be unethical and
dishonest.
Defense Mechanisms of personality
Defense mechanisms are unconscious psychological strategies used to reduce anxiety and
emotional stress.
Freud believed that the ego uses defense mechanisms to protect individuals from emotional
conflict and stress. Defense mechanisms help people cope with difficult emotions and situations.
Although they may reduce anxiety temporarily, excessive use may distort reality.
Some common defense mechanisms are:
1. Repression
2. Projection
3. Rationalization
4. Sublimation
Examples
(a) A student gives excuses after performing poorly in an examination.
(b) An employee blames workplace stress instead of admitting personal mistakes.
1. Repression
Repression is the unconscious blocking of painful memories or thoughts.
In repression, the mind pushes unpleasant memories or experiences out of conscious awareness
to reduce emotional pain and anxiety.
Examples
(a) A student forgets an embarrassing classroom incident after feeling emotionally upset.
(b) A worker avoids remembering a stressful workplace conflict after changing jobs.
2. Projection
Projection is attributing one’s own unwanted feelings or thoughts to others.
People deny their own negative emotions and instead believe that others possess those feelings.
Projection reduces personal anxiety by shifting uncomfortable emotions onto others.
Examples
(a) A student who dislikes group work accuses classmates of being uncooperative.
(b) A dishonest employee constantly suspects coworkers of dishonesty.
3. Rationalization
Rationalization is giving logical or socially acceptable excuses for mistakes or failures.
People use rationalization to protect self-esteem and avoid accepting responsibility for failures or
weaknesses.
Examples
(a) A student who fails an exam says the questions were too difficult.
(b) A salesperson who misses a sales target blames the market situation instead of poor preparation.
4. Sublimation
Sublimation (shifting) is changing unacceptable impulses into socially acceptable activities.
Sublimation redirects negative emotions into productive and positive behavior. It is considered
a healthy defense mechanism.
Examples
(a) A person with aggressive energy becomes successful in competitive athletics or military
training.
Behavioral Theory of Personality
Behavioral theory explains personality as a result of learning and environmental experiences.
Behaviorists believe personality develops through reinforcement, punishment, conditioning,
and observation. Behaviors that are rewarded tend to continue, while punished behaviors
decrease. Personality is shaped mainly by experiences and environment.
Behavioral theory mainly includes:
1. Observational Learning
2. Reinforcement Theory
Examples
(a) A student praised for punctuality becomes more disciplined.
(b) Employees rewarded for teamwork become more cooperative at work.
1. Observational Learning
Observational learning is learning behavior by observing and imitating others.
Albert Bandura explained that people learn behaviors by watching parents, teachers, friends,
leaders, and role models. Behaviors that receive rewards are more likely to be copied.
Examples
(a) Students learn respectful behavior by observing teachers.
(b) New employees imitate professional communication styles of experienced managers.
2. Reinforcement Theory
Reinforcement theory explains how rewards and punishments shape behavior and personality.
Behavior is influenced by its consequences. Positive outcomes strengthen behavior, while negative
consequences reduce unwanted behavior. Repeated reinforcement shapes personality traits over
time.
Reinforcement theory mainly includes:
i. Positive Reinforcement
ii. Punishment
Examples
(a) Teachers reward students for completing assignments on time.
(b) Companies give bonuses to employees for excellent performance.
i. Positive Reinforcement
Positive reinforcement involves giving rewards to increase desired behavior.
When people receive rewards after a behavior, they are more likely to repeat that behavior. Positive
reinforcement encourages positive personality traits such as responsibility, confidence, and
cooperation.
Examples
(a) A student receives praise for active class participation and continues participating.
(b) Employees receiving promotions for hard work become more motivated and productive.
ii. Punishment
Punishment involves giving unpleasant consequences to reduce unwanted behavior.
Punishment discourages negative behavior by introducing unpleasant consequences. Although
punishment may reduce undesirable actions, excessive punishment may create fear, anxiety, or low
self-esteem.
Examples
(a) A student receives detention for repeatedly disturbing the class.
(b) An employee receives a warning letter for violating company rules.
