Mooney Face Test

The Mooney Face Test was developed by Craig Mooney and his results published in 1957 as “Age in the development of closure ability in children.” In the test, participants are shown low-information two-tone pictures of faces, and are asked to identify features and distinguish between real and "false" faces. Since facial recognition occurs mainly in the right hemisphere of the brain, it is a test of right-brain functionality and a concept he called "perceptual closure," or the ability to form coherent mental pictures with very little visual information.
