Models of personality structure

In the present chapter, models of personality structure are discussed. With the term “personality structure” we refer to the organization of the various features of personality as based in theory or in empirical findings. By adding the term “models,” the structure quality seems a bit tautological because a model is usually recognized by its typical form or its organization. Most of the ambiguity in the expression “models of personality structure,” is, however, in the term “model” (from the Latin modulus, diminutive of measure or standard), as the term has accrued a variety of functions which can appear at different levels of abstraction.
