Face in a cloud by Neil Usher - This image serves as an example of pattern recognition enhancement.

Pattern recognition enhancement is an increase in a person's ability and tendency to recognise patterns (usually faces) within vague stimuli.

This innate ability which human beings possess in everyday life is referred to by the scientific literature as pareidolia and is a well documented phenomenon.[1][2][3] Common examples of this include spotting faces in everyday objects, such as the front of a car, or seeing different objects in clouds.[4]

During this effect, pareidolia can be significantly more pronounced than it would usually be during a sober state.[5] For example, remarkably detailed images may appear embedded in scenery, everyday objects may look like faces, and clouds may appear as fantastical objects, all without any visual alterations taking place. Once an image has been perceived within an object or landscape, the mind may further exaggerate this recognition through the hallucinatory effect known as transformations, which goes beyond pareidolia and becomes a standard visual hallucination.

Pattern recognition enhancement is often accompanied by other coinciding effects such as acuity enhancement and colour enhancement.[6][7] It is most commonly induced under the influence of mild dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline.
