The Rorschach test, named after the renowned Swiss psychiatrist and neurologist Hermann Rorschach who developed it in 1921, consists of ten cards bearing symmetrical inkblots obtained by folding a sheet of paper in half. Five cards are in black and white, and five are in color. Participants observe these cards one by one and interpret them. This principle is frequently used in advertising, such as in a commercial where viewers must pay close attention to identify acts of violence against children depicted, with the aim of condemning them. It is possible to see only a simple inkblot, which amounts to ignoring the violence, or to grasp the hidden meaning of the blot and thus become aware of this violence. This capacity for interpretation is illustrated by World Vision.
