shy of his 70th birthday. Allport's trait theory Allport contributed to the trait theory of personality, and is known as a "trait" psychologist. He did not believe that people can be classified according to a small number of trait dimensions, maintaining that each person is unique and distinguished by peculiar traits. In one of Allport's own articles, Concepts of Trait and Personality (1927), Allport states that traits are "habits possessed of social significance" and become very predictable, traits are a unit of personality. Allport states that the personality of a person is the single most unique thing about a person. One of his early projects was to go through the dictionary and locate every term that he thought could describe a person. From this, he developed a list of 4500 trait-like words. He organized these words into three levels of traits. This is similar to Goldberg's fundamental lexical hypothesis, or the hypothesis that humans develop widely used, generic terms for individual differences in their daily interactions over time. Allport's three-level hierarchy of traits are: 1. Cardinal trait - These traits are rare but is the trait that dominates and shape a person's behavior. These are the ruling passions/obsessions, such as a need for money, fame, etc. 2. Central trait - These traits are general characteristics found in some degree in every person. These are the basic building blocks that shape most of our behavior although they are not as overwhelming as cardinal traits. They influence but do not determine behavior. An example of a central trait would be honesty. 3. Secondary trait - These traits are the bottom tier of the hierarchy and are not as apparent as central traits. Secondary traits are characteristics seen only in certain circumstances (such as particular likes or dislikes that a very close friend may know). They must be included to provide a complete picture of human complexity. The Development of the Proprium 1.

Sense of self-identity (second year) Though understanding whom they are by having a significance in their name has. This can then give them a sense of how they are and what that can mean socially. 3.
