The psychology in the art

The art is a source of expression very extensively that changed very much with step of the decades, in the last years it changed and caused one of the biggest breaks in the history of the art, since there wanted to part with his ancient characteristics provinientes of last centuries, this is considered to be the beginning of a new age inside the art.

The history of the contemporary art is divided in three different stages, taking the Second World war as a point of reference in majority since it was the event that indicated his thoughts to all the individuals who were living united in the course of the 20th century, modifying this way, and consequently generating new instruments of work

According to my opinion they are the most important artists of last years who went in the highest step to this new age in the art:

Ai Weiwei
Jeff Koons ​
Gabino Amaya Cacho
Yayoi Kusama
Damien Hirst

Do they think that the art is important in the psychological development of the persons?
