like the Man in the Moon or the Moon rabbit. The concept of pareidolia may extend to include hidden messages in recorded music played in reverse or at higher- or lower-than-normal speeds, and hearing voices (mainly indistinct) or music in random noise, such as that produced by air conditioners or fans. Scientists have taught computers to use visual clues to "see" faces and other images.


Etymology

The word derives from the Greek words ''

Karl Ludwig Kahlbaum Karl Ludwig Kahlbaum (28 December 1828 – 15 April 1899) was a German psychiatrist. Life and career In 1855 he received his medical doctorate at Berlin, and subsequently worked as a physician at the mental asylum in Wehlau. For a period he wa ...
—for example in his 1866 paper "" ("On Delusion of the Senses"). When Kahlbaum's paper was reviewed the following year (1867) in ''The Journal of Mental Science'', Volume 13, was translated into English as "pareidolia", and noted to be synonymous with the terms "...changing hallucination, partial hallucination, ndperception of secondary images."


Explanations

Pareidolia can cause people to interpret random images, or patterns of light and shadow, as faces. A 2009 magnetoencephalography study found that objects perceived as faces evoke an early (165 ms) activation of the
fusiform face area The fusiform face area (FFA, meaning spindle-shaped face area) is a part of the human visual system (while also activated in people blind from birth) that is specialized for facial recognition. It is located in the inferior temporal cortex ( ...
at a time and location similar to that evoked by faces, whereas other common objects do not evoke such activation. This activation is similar to a slightly faster time (130 ms) that is seen for images of real faces. The authors suggest that face perception evoked by face-like objects is a relatively early process, and not a late cognitive reinterpretation phenomenon. A
functional magnetic resonance imaging Functional magnetic resonance imaging or functional MRI (fMRI) measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area o ...
(fMRI) study in 2011 similarly showed that repeated presentation of novel visual shapes that were interpreted as meaningful led to decreased fMRI responses for real objects. These results indicate that the interpretation of ambiguous stimuli depends upon processes similar to those elicited by known objects. These studies help to explain why people generally identify a few lines and a circle as a "face" so quickly and without hesitation. Cognitive processes are activated by the "face-like" object which alerts the observer to both the emotional state and

of the subject, even before the conscious mind begins to process or even receive the information. A "stick figure face", despite its simplicity, can convey mood information, and be drawn to indicate emotions such as happiness or anger. This robust and subtle capability is hypothesized to be the result of eons of

favoring people most able to quickly identify the mental state, for example, of threatening people, thus providing the individual an opportunity to flee or attack pre-emptively. This ability, though highly specialized for the processing and recognition of ''human'' emotions, also functions to determine the demeanor of wildlife.


Examples


Mimetoliths

A mimetolithic pattern is a pattern created by rocks that may come to mimic recognizable forms through the random processes of formation, weathering and erosion. A well-known example is the Face on Mars, a rock formation on Mars that resembled a human face in certain satellite photos. Most mimetoliths are much larger than the subjects they resemble, such as a cliff profile which looks like a human face. Picture jaspers exhibit combinations of patterns such as banding from flow or depositional patterns (from water or wind), or dendritic or color variations, resulting in what appear to be miniature scenes on a cut section, which is then used for jewelry.

Mars canals

A notable example of pareidolia occurred in 1877, when observers using telescopes to view the surface of Mars thought that they saw faint straight lines, which were then interpreted by some as canals (see Martian canals). It was theorized that the canals were possibly created by sentient beings. This created a sensation. In the next few years better photographic techniques and stronger telescopes were developed and applied, which resulted in new images in which the faint lines disappeared, and the canal theory was debunked as an example of pareidolia.

Art

Renaissance artists often used pareidolia in paintings and drawings:
Andrea Mantegna Andrea Mantegna (, , ; September 13, 1506) was an Italian painter, a student of Roman archeology, and son-in-law of Jacopo Bellini. Like other artists of the time, Mantegna experimented with perspective, e.g. by lowering the horizon in orde ...

wrote of pareidolia as a device for painters, writing: In twentieth century art ''Salem'', a 1908 painting by Sidney Curnow Vosper, gained notoriety due to a rumour that it contained a hidden face, that of the devil. This led many commentators to visualize a demonic face depicted in the shawl of the main figure, despite the artist's denial that any faces had deliberately been painted into the shawl. Surrealist artists such as

Medical education, radiology images

, has written that pareidolia is used to teach medical trainees to assess for spinal fractures and spinal malignancies (cancers). When viewing spinal radiographs, normal bony anatomic structures resemble the face of an owl. (The spinal pedicles resemble an owl's eyes and the spinous process resembles an owl's beak.) But when cancer erodes the bony spinal pedicle, the radiographic appearance changes such that now that eye of the owl seems missing or closed, which is called the "winking owl sign". Another common pattern is a "Scottie dog sign" on a spinal X-ray. In 2021, Foye again published in the medical literature on this topic, in a medical journal article called "Baby Yoda: Pareidolia and Patternicity in Sacral MRI and CT Scans". Here, he introduced a novel way of visualizing the

software, which falsely detects and then exaggerates features such as eyes and faces in any image. The features can be further exaggerated by creating a feedback loop where the output is used as the input for the network. The adjacent image was created by iterating the loop 50 times. Additionally the output can be modified such as slightly zooming in to create an animation of the images perspective flying though the surrealistic imagery.

in popular music, in which a listener claims a message has been recorded backward onto a track meant to be played forward, have also been described as auditory pareidolia. In 1995, the psychologist Diana Deutsch invented an algorithm for producing phantom words and phrases with the sounds coming from two stereo loudspeakers, one to the listener's left and the other to his right, producing a phase offset in time between the speakers. After listening for a while, phantom words and phrases suddenly emerge, and these often appear to reflect what is on the listener's mind.
