Lifeless Objects Stare at You Everywhere. A New Study Explains Why They Won't Quit
When you see a face in a cloud, in the slots of a power point, or on the side of a house, there's a term for it: face pareidolia. This strange perception phenomenon makes lifeless, inanimate objects appear to have facial features – the basic shapes of two eyes and a mouth is often all it takes to imagine a face gazing back at you. ...
"This basic pattern of features that defines the human face is something that our brain is particularly attuned to, and is likely to be what draws our attention to pareidolia objects," says behavioural neuroscientist Colin Palmer from the University of New South Wales (UNSW) in Australia.
"But face perception isn't just about noticing the presence of a face. We also need to recognise who that person is, and read information from their face, like whether they are paying attention to us, and whether they are happy or upset." ...
That distinction – not just seeing a face, but reading social and emotional information from it – could tell us how deeply pareidolia objects are processed within our brain and visual systems. ...
In new research, Palmer and fellow UNSW psychologist Colin Clifford sought to investigate whether face pareidolia involves the activation of sensory mechanisms designed to register social information from human faces. ...
The results, the team suggests, mean that face pareidolia goes beyond being a purely cognitive or mnemonic effect, reflecting information processing in higher-level sensory mechanisms in the visual system, which are usually used to read emotional states on faces – such as whether someone is smiling and happy with us, downcast, or even furiously angry.
That ability to not just perceive face shapes but read facial emotions is extremely important, given what faces can reveal about those who wear them. ...
