Psychology is the academic discipline concerned with the inner life (knowing, feeling and striving) and the behavior of people. It generally does this by following the scientific method, but in some cases it makes use of symbolic interpretation and critical analysis, following the example of other social sciences.
The goal of psychology is to acquire knowledge about the behavior of humans, both in their everyday environment and under special circumstances. With the emergence of the behavioral movement, the object of psychology was reduced to the outwardly observable and measurable behavior of animals humans, because the inner life would not be objectively registered by scientific observation, but only subjectively by introspection and understanding. This limitation has been reversed, among other things by the 'cognitive revolution' in psychology, by the great social importance of psychotherapy and by the connotations that the word 'psychology' evokes in everyday language use.
