Psychology’ s so-called Big Five personality trait includes five basic kinds of personality factors. The first factor in the Big Five personality trait is the extraversion-introversion inclination. That is, the degree to be outgoing, easy to get along with, or friendly. We can also count out the number of friends to see whether a personality trait is extraversion or introversion. The second factor is the neuroticism inclination. If you say that someone is neurotic, you mean that they are always unreasonably frightened or worried about something that you consider unimportant. The third factor is the agreeableness inclination. If someone is agreeable, they are pleasant and try to please people. Sometimes if a person was too agreeable in personality trait, the biased reward system in brain is what to blame. The fourth factor is the conscientiousness inclination. Someone who is conscientious is very careful to do their work properly. A conscientious man or woman has the ability to know what is right and what is wrong, and they always try their best to do the things right. The fifth factor is the openness inclination. If you describe a person or their character as open, you mean they are honest and do not want or try to hide anything or to deceive anyone. If you describe a situation, attitude, or way of behaving as open, you mean it is not kept hidden or secret.
In summary, extraversion-introversion, neuroticism, agreeableness, conscientiousness and openness are factors of Big Five personality traits.
