Piggy-Blackfoot test

The pig black foot test (also called SF test) is a projective test method for psychodiagnosis of the child, developed by Louis Corman. The test is similar to the TAT (themed apperception test) or the Columbus test and was first published in 1961. The German version was published in 1977. The blackfoot test consists of a test card with 18 picture cards.

First the child is shown the opening picture. It is asked: "Who is that?" You can see a boar (corresponds to the father), a sow (corresponds to the mother), two white pigs (siblings) and the hero of the test, piggy blackfoot (SF). SF experiences many adventures on the farm. The children can choose their favorite images and tell a story. The test can also be used in adults. It is said to be a story for children to tell the adults.

The narrated story is recorded and the subjects are asked to sort their favorite images in order. Then the most unpopular images have to be sorted. Lastly, identification is requested. So, "Who do you want to be on the picture?"

On each image of the test, conflict situations are presented, and potentially defensive mechanisms are of great interest.

Reliability and validity of projective procedures are often inadequate. Nevertheless, these "free" test methods, carefully interpreted, allow an insight into unconscious mind processes. Single-level Edit source text
