An individual’s personality gets shaped by a wide variety of factors, which often act in conjunction. Some of the factors shaping personality of an individual are as follows :
Heredity
Heredity implies all those characteristics that an individual inherits from his parents. Heredity affects the physical and mental makeup of a person.
Endocrine glands
Endocrine glands such as the pituitary, thyroid, pancreas, adrenals gonads, etc. play an important role in shaping personality of an individual. Over secretion or the under secretion of hormones produced by various glands may adversely affect the personality of an individual.
Family
Family is one of the most important factors influencing personality of an individual. The elements related to family such as structure of family, socio-economic status of family, emotional, academic and cultural environment in family, interactions between family members, child rearing practices followed by parents, etc. have significant effects on personality of an individual.
Peer group
Peers are a pervasive aspect of our social life. Peers surround us in our everyday lives from early childhood until old age. Members of the same classroom, workplace or sports club, etc. constitute peer group. The peer group may influence personality in a positive as well as negative manner.
School
The school plays an important role in the personality development of students. The elements related to school like the teaching learning process, academic activities and co curricular facilities provided by school, teachers’ rapport with students, school discipline and policies etc. have a significant impact on the personality of students.
Mass media
Internet and other forms of mass media are now deeply integrated in almost everyone’s daily lives. Mass media is a source of entertainment, informal education, socialization, etc. to many of us.
Culture
Cultural factors also play an important role in shaping the personality of an individual. Every culture has its own set of values, beliefs, norms, etc. influencing thoughts, feelings and behavior patterns of an individual.
Carl Jung, a Swiss Psychiatrist classified people on the basis of mental characteristics into introverts and extroverts as follows
1. Introverts : Introvert individuals tend to look within themselves for stimulation. Mostly they are shy and reserved. They prefer to work alone and avoid social contacts.
2. Extroverts : Extrovert individuals are aroused by external stimulation. They are social, outgoing, mix easily with others and prefer jobs that bring them in contact with others.
Allport’s theory of personality is one of theories based on the trait perspective to study personality.
A trait is a relatively enduring and consistent way of thinking, feeling and acting. That means the trait is consistently found in an individual over a period of time.
1. Cardinal Trait : It is a single trait that dominates an individual’s entire personality. The person becomes known specifically for this trait. It dominates and shapes a person’s behavior for their whole life.
2. Central Traits : These traits are general characteristics that form the basic foundation of a personality of an individual. Around 5 to 10 traits that best describe an individual’s personality are called central traits. Central traits are the building blocks of our personality.
3.Secondary Traits : These traits appear only in specific situations and hence are narrow in effect. Such traits play a very minor role in determining the personality of an individual because such traits are situational.
