Mooney Face Test

The Mooney Face Test was developed by Craig M. 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. It is a test of a concept he called "perceptual closure": the ability to form coherent mental pictures with very little visual information.

A study conducted with 370 participants identified an association between performance on the Mooney Face Test and a polymorphism in the RAPGEF5 gene.
