As mentioned in the previous tutorial, Human Perception, illusions can be caused by mental disorders or misreading of the sensory data obtained from the external environment. For now, we will look at the latter.
One of the most famous of these is the Doppler Effect, where a noise situated close to you has a higher pitch of sound to that of a sound further away. This is the case if you should and get an echo, your voice will always sound deeper in the echo when it is not. This is effectively an illusion.
As mentioned previously, the study of illusions in sufferers of a mental disorder provides a key to a deeper understanding of what is going on in their minds. This is also the case of a healthy brain, where the study of illusions can work out the parameters at which it compensates for its own lack of ability.
It is worth noting that the trial and error the sensory organs function have, they are as just as foolproof as any other conscious human thought. The chances of your brain not being able to guess the spatial distance of a fuzzy moving object are the same lack in the ability that people have in typing an error-free document
In this sense, illusions are studying the perceptions and sensory data obtained from situations where human error prevents us from seeing the real deal.
Another interesting fact is that the retina is read by the brain every 0.1 seconds, meaning that you are not actually seeing anything in the present, but something that just happened a fraction of a second ago.
