What is the Meaning of: Personality | Concept and Definition of: Personality

Personality is a psychological construct that covers all of the characteristics of a person. The American Gordon Allport defined personality as being the dynamic organization of the psychophysical systems determining a way of thinking and acting. This organization is unique in each person in its process of adaptation to the environment.

However, experts have established several types of definitions for the concept of personality. This is the reason why appear additive definitions, which are built on the basis of the sum of a set of characteristics; the inclusive, which underline the character organized and structured this addition; the hierarchical, which recognize the integrated structure of the elements forming the personality, but which state the balance of elements over others; and definitions of adaptation to the environment, leaving as an integration of the elements, but who believe that the Organization depends on the environment where the individual lives.
Studies on the personality contain two major themes: the interpersonal functioning (intrapsychic, unobservable directly) and individual differences (the features that make that a certain person is different from another).
Is of German origin English psychologist Hans Eysenck proposed a model of personality which is structured on three dimensions: psychotisme, extroversion and nevrotisme. Because of the initials, this type of study is known as the model PEN.
