Caputo suggests that the dramatic effects might be caused by a combination of basic visual distortions affecting the face-specific interpretation system.
The visual system starts to adapt after we receive the same information over time (this is why you can experience visual changes by staring at anything for a long time) but we also have a system that interprets faces very easily.
This is why we can ‘see’ faces in clouds, trees, or even from just two dots and a line. The brain is always ‘looking for faces’ and it is likely that we have a specialised face detection system to allow us to recognise individuals whose faces actually only differ a small amount in statistical terms from other people’s.
