People often use the words "expression", "expressional person", meaning, first of all, the emotional personality expressing emotions is bright or extraordinary. However this term is used not only in psychology and sociology, but also in conflictology, art criticism, chemistry.
The word "expression" comes from Latin ex-pressio — "expression, squeezing, forcing". The Greek analog of the term — a drastik, meaning vigorous activity, respectively, a parallel concept – dynamics. The expression is an external expression, first of all, of feelings and experiences. It can be tears, exclamations, shouts, dejectedness or apathy. In many respects this cultural concept, expression forms at the different people differ and, respectively, the relation to its manifestation differs. So, tears – almost universal sign of a grief and grief, but a form of this reaction – when and as it is long possible to cry - define standards of culture. On expressivity, psychologists claim, also the sociocultural environment of formation of the personality significantly influences. Though biologists prove that the expression at the person is genetically determined, it strongly depends on process of the learning directed by social norms.
Artists expressionists learned "to catch" external expression of emotions. They understood an expression as esthetic property of a subject, its artistry and fullness thoughts and feelings of the author. If the viewer managed to see these feelings, then the work on the truth in expressive way. However, such works are not deprived also external expressiveness, bright paints, the memorable images, accurate lines. Images of the Hellenistic sculpture, the work by artists of Mannerism, the Western European Gothic style are expressional. Expressionists call P. Bruegel Starschi, I. Bosch, El Greco and Feofan Grek. It is obvious that such currents as cubism, actually expressionism, hi-tech and the Japanese minimalism are expressionistic.
