Perceptual experts are distinguished by an extraordinary capacity to identify objects rapidly and accurately. There are several modalities of Perceptual Expertise: visual, auditory, tactil, among others.

In the present case we are before visual expertise. Although almost anyone possesses perceptual expertise to some extent, there are people who might have a stronger ability to find out what an upside down image of a symbol or an animal is about, while there are others with a great perceptual expertise to read upside down. Again, the present example says that after some practice Carol was able to read upside down, but, many of us could have this ability and are not aware of it.
