Personality: Personality also refers to the pattern of thoughts, feelings, social adjustments, and behaviors consistently exhibited over time that strongly influences one's expectations, self-perceptions, values, and attitudes.

JUNG Classification of Personality

• His personality theory is known as an analytic theory or analytical psychology.
• Carl Jung suggested that all human beings share certain unconscious ideas because we are all human and were created from similar evolutionary circumstances and common ancestors.
• The unconscious that we all share is called the collective unconscious.
• Each individual has his own self-actualization. Jung expressed libido in a very comprehensive way, he equated libido as life energy.
• In light of libido, Jung proposed two types of personalities— extroverts and introverts.
• The persons in whom life energy (libido) flows inward are known as introvert while, persons whom the life energy flows outward are termed as an extrovert.
• In other words, the extraversion orients a person toward the external world while the introversion drives a person toward the inner, subjective world.
• According to Jung introvert and extrovert function under four aspects-sensations, feelings, thinking, and intuition.

FREUD:

• The first modern theory of personality was developed by Sigmund Freud (1923) that is known as the psychoanalytic or psychodynamic theory of personality. 
• According to Freud our most behavior is caused by thoughts, ideas, and wishes that are created in a person‘s brain.
• These are not easily accessible by the conscious part of the mind but the unconscious mind.
• According to him, the mind could be divided into three abstract categories- the id, the ego, and the superego.

ALLPORT:

• Gordon Allport (1897-1967) was the first personality theorist who adapted the trait approach of personality theory.
• The trait theory approach is one of the most important and largest fields of personality psychology.
• According to this theory, personality is a composition of broad traits.
• Allport (1929) defined ―A trait is a tendency to a reaction which when measured with reliability demonstrates the independence of other variables.

MUNN:

• Personality may be defined as the most characteristics, integration of an individual’s, structure, attitudes, capacities, abilities, and aptitudes
