He was widely noticed for his "drip technique" of pouring or splashing liquid household paint onto a horizontal surface, enabling him to view and paint his canvases from all angles.Pollock was introduced to the use of liquid paint in 1936 at an experimental workshop in New York City by the Mexican muralist David Alfaro Siqueiros. In the summer, he went to Dartmouth College to study Jose Clemente Orozco's 3,200 square foot mural, “The Epic of American Civilization.”[13] He later used paint pouring as one of several techniques on canvases of the early 1940s, such as Male and Female and Composition with Pouring I. After his move to Springs, New York, he began painting with his canvases laid out on the studio floor and he developed what was later called his "drip" techniqueFrom 1938 to 1942 Pollock worked for the WPA Federal Art Project. During this time Pollock was trying to deal with his established alcoholism; from 1938 through 1941 he underwent Jungian psychotherapy with Dr. Joseph L. Henderson and later with Dr. Violet Staub de Laszlo in 1941–42. Henderson engaged him through his art, encouraging Pollock to make drawings. Jungian concepts and archetypes were expressed in his paintings. Some historians have hypothesized that Pollock might have had bipolar disorder.
