In psychology , a greeble (plural: greebles ) is a three-dimensional appearing object, usually carefully designed using computer graphics , which serves as a visual stimulus in cognitive psychological research into object and face perception .

First use

The first greebles were designed at Yale University by Scott Yu under the supervision of Michael J. Tarr and Isabel Gauthier. Isabel Gauthier used it in her dissertation , and its description was first published in 1997 in the journal Vision Research . The name Greebles comes from the psychologist Robert Abelson.

Cognitive psychology

A greeble , for example, represents a face-like object with limited features: less recognizable facial attributes, but in a common basic arrangement. To put it more simply: A greeble somehow looks like a face, but in no way represents a real face. This makes it difficult to assign the greeble on the basis of the presence of a single property, and it is precisely this fact that the test subjects are supposed to do in cognitive psychology experiments bring to perceive all the characteristics of a greebles in relation to each other and to use them for a possible group assignment. Greebles are thus - like real faces - perceived configurally , i. H. not only perception of the individual components, but perception of the totality of all components and their arrangement to one another.

Greebles can be designed for special test arrangements. Yu's originals (symmetrical and asymmetrical) are available from Michael Tarr's website.
