The document discusses concepts and definitions of personality from various theorists. It defines personality as a unique set of relatively stable traits and characteristics that determine one's adjustment to the environment. Personality is influenced by personal, environmental, biological, psychological, and social factors. Major theories discussed include trait theory, Jung's theory of extraversion vs introversion, Allport's trait theory involving cardinal and central traits, and the Big Five approach.

2. Concepts
 The word personality comes from the Latin root
persona, meaning "mask." According to this root,
personality is the impression we make on others; the
mask we present to the world.
 Personality is defined as "a unique set of traits and
characteristics, relatively stable over time.“ The
definition further suggests that personality does not
change from day to day. Over the short-term, our
personalities are relatively set or stable. However,
definition does not suggest that personality is
somehow rigid, unchangeable, and cast in concrete.
Definition recognizes that, over a longer term,
personality may change.

3. Definitions
 J.B. Watson (1930) : “ Personality is the sum of
activities that can be discovered by actual
observations over a long enough period of time to
give reliable information.”
 M. Prince (1929): Personality is the sum total of all
biological innate dispositions, impulses,
tendencies, appetites, and instincts of the
individual and the dispositions and tendencies
acquired by experience.”

4.  After analyzing 49 definitions by eminent
persons, Allport (1948) defined “Personality is the
dynamic organization within the individual of
those psychophysical systems that determine his
unique adjustment to his environment.”

5. Characteristics
 Personality is an internal process that guides behaviour.
 Gordon Allport (1961) makes the point that personality is
psychophysical, which means both physical and
psychological.
 Biological and genetic phenomena do have an impact on
personality.
 Child (1968) makes the point that personality is stable – or
at least relatively stable.
 Child (1968) includes consistency (within an individual)
and difference (between individuals) in his definition,
 Allport (1961) refers to characteristic patterns of behavior
within an individual.

6. Nature of Personality

 Helps in adjusting the individual with the
environment

12. Jung Theory
 Extraversion - *Extraversion* is the tendency to
look to the outside world, especially people, for
one's pleasures. Extraverts are usually outgoing
and they enjoy social activities, but they are
uncomfortable when they are alone.
 Introversion - *Introversion* refers to a tendency
to prefer the world inside oneself. The more
obvious aspects of introversion are shyness, a
distaste for social functions, and a love of privacy.

13. Trait theory
 Allport Theory
 Cattell 16 PF theory

14. Allport theory
 He identified 17953 terms to define personality.
 After careful analysis he found 4541 term to define an
individual

15. Allport Trait theory
 Personality: A Psychological Interpretation (1937)
 Allport defined Trait as “ a generalized and
focalized neuropsychsic system with the capacity
to render many stimuli functionally equivalent,
and to initiate and guide consistent forms of
adoptive and expressive behavior (Allport, 1937).

16. Classification of traits (Allport)
 Cardinal traits : the traits ruling the personality of the
individual e.g sense of humour
 Central traits : easily detected traits that all people
have a certain number. E.g. shyness, timidity, honesty
 Secondary traits : Less important, style of walking, etc

17. Cattell 16 PF
 171 basic traits
 Common traits it is found widely distributed in
general population . E.g Honesty, cooperation
 Unique traits : these traits are possessed by particular
persons e.g emotional stability
 Surface Traits : easily recognized e.g Curisioty,
 Source traits : it determines the behavior

19. Super traits ( Type –cum-trait)
