Example of a Mooney face, inverted (left) and right-side-up. The Mooney Face Test, developed by Craig M. Mooney, was first introduced in his 1957 article “Age in the development of closure ability in children.” [1] Participants in the test are shown series of black and white distorted photographs, presented in such a way that would require them to perform closure.

All images used were high quality, with the subject standing face on and looking straight at the camera lens, which was positioned at head height. There are two versions of the test, one short version comprising 40 "same-or-different" 2AFC decisions and another longer version with 164 decisions. These tests, complete with normative data, are ...
Any human face can be considered to be a combination of these standard faces. For example, one's face might be composed of the average face plus 10% from eigenface 1, 55% from eigenface 2, and even −3% from eigenface 3. Remarkably, it does not take many eigenfaces combined together to achieve a fair approximation of most faces.
The meta analysis by McKelvie (1995) indicated that internal consistency and test-retest reliability of the VVIQ were acceptable and minimally acceptable respectively, while alternate form reliability was unacceptable. McKelvie (1995) reported only a weak correlation (r =.137) between VVIQ imagery ability and memory performance.
