Personismus is a way of thinking in personality psychology, which traces back to properties of the acting person stable patterns (so-called internal attribution). While many personal characteristics akin to the laity-psychology for example says someone is leader/follower, friendly/unfriendly, smart/stupid, neat/messy, musical/unmusikalisch, etc., the empirical finding is rather ambiguous. The scientific proof of such human qualities is extremely difficult. Conley (1984) presented time and again various personality tests to a group of test subjects over a period of 40 years and found a high stability of intelligence, a medium-sized stability of extraversion and neuroticism, while volatile settings such as self-esteem and life satisfaction. A theory of absolute Personismus would assume the complete independence of the behavior of its situational context, therefore the relative Personismus influences of the environment. This is the classic model of personality psychology.
“Other models are about different situations across consistent” behavior on properties of the situation back (Situationism “, so the radical Behaviourism), or on the interaction of people and situation properties (sog. Interactionism “).” Introversion and extroversion are two poles of a personal property. The terms used in the differential psychology, to characterize the interaction with the environment. Extremes are rare here; the scale is continuous. Using personality tests, it is possible to determine the individual position of the subjects on the Extraversion/Introversion scale.

The big five and the five factor model (FFM) is a model of personality psychology, which postulates five main dimensions of personality.
… This was the opinion that personality characteristics will be reflected in the language. On the basis of lists with over 18,000 words, five very stable, independent and largely stable to cultural factors, the big five, were found by factor analysis. On the basis of this model Costa and Robert R. McCrae developed Paul t. with the NEO five factors inventory (NEO-FFI) today an international personality test for adolescents and adults.
