Document Summary
We naturally tend to group similar things together. Preference for faces is innate: there was an experiment in which two stimuli were presented: one had the same shape and features of a face and one was the same thing upside down. Babies preferred the one that resembled a face. Own race effect: difficulty recognizing people from other races. When people are given instructions to focus on only the top of the face they have a very difficult time shows that we process entire faces automatically and use that to make our judgment. This is not something that we can easily turn on and off. The inversion effect: when we flip the face, we can recognize it but it"s harder to focus on detail. Easier to turn off the illusion when it"s upside down. We see this illusion because our visual system is used to seeing faces pointed out not in.
