In psychology, the Trait Theory is used by psychologists to understand and analyse the characteristic features of human personality,
Personality traits can be defined as the characteristics or features which are expressed by different individuals.
The personality traits are usually different for different persons and so they are unique for a particular person.
These traits are influenced by both hereditary and environmental factors.
The hereditary influence is derived from the parents and the environmental influence is derived when the individual adapts himself to survive in the environment he is exposed to.
