Influenced by the discoveries of electromagnetism and the gravitational field in the 19th century, Gestalt Psychology assumed that in human perception there was a “visual field”. It claimed that human’s understanding of any visual figure, its form or profile, came from the organization of our cognitive system; they were not collections of individual parts. When we see a rose, we see its form and color, and together with what we have learned or experienced about roses previously, our feelings about it become a “field”.
