잭슨 폴록(Jackson Pollock, 1912-1됐)은 미국의 추상표현주의(Abstract ExpresslOrusm) 를 대표하는 선구적 작가이다. 미국의 모더니즘 미술에서 2차원 평면성을 가장 먼저 캔버스에 도입한 그는 전통미술의 표현방법과 달리 물감을 뿌리거나 흘리는 기법으로 캔버스에 구체적 형상이나 이미지의 흔적을 말끔히 제거한 평면성을 드러내었다(데브 라 브리커 발켄 Debra Bricker Balken, 2006 13, 14) 미국의 평론가 클레멘트 그린버 그 (Clement Greenberg, 1991 29 33) 가 1960년에 주장한 회화의 평면성은 1947년 이 후 폴록의 드리핑 기법에 의해 표현됨으로써 그는 미국의 추상표현주의를 대표하는 작가로 인정을 받았다. 장 ？p 다발(Jean Luc Daval, 1988 99)은 폴록의 드리핑 회화가 1947년부터 1951년 사이에 그 절정을 이루는 가운데 미국 미술에 지대한 역할을 하였으며， 그의 활동은 모든 미국 미술을 추상표현주의로 귀결시켰다고 하였다.
Jackson Pollock's paintings were both praised and blamed at the same time from the many of art critics and art historian. Pollock was blamed in that he rejected the classic painting that is the realistic method technic in Art. But Clement Greenberg insists that Pollock's the one of the greatest artist of the modern art in the America. Greenberg said that it is because Pollock is to seek for the flatness of his works in the dripping painting not seeking to the three mention technic of the art works as in the classic artist's works. Pollock's dripping work is interpreted for the image of regressions with anxiety as defence machinism in the psychoanalysis. The reason why he appeared the image of the regression in his work is the anxiety with in his actual life. His anxiety is that he might be succeed in his life in the future as greatest artist. Pollock's dripping painting is appeared the image of regression for defence mechanism in psychoanalysis as conquering anxiety of life. He's regression image is represented with similar to the kid's scribble image. Firstly, Pollock's works is the same to representing the image in unconscious mind with kid's scribble. Secondly, his work's is similar to as in the placement pattern of kid's scribble. Pollock's all over painting is the same thing to the scribble with the image of shape full formed in the paper. Pollock's painting is illustrated differently for classic works in case of interpreting psychoanalysis. In this study of Pollock's work by psychoanalysis, it will give us meaning in that we have proposed new method of art work's evaluation and art critic for student.
