It is time for a new update on Cognitive Science! Last time I already gave a short introduction on the subject I would like to talk about in this blog, namely: Visual Perception.
First question that comes to mind (hopefully) is without doubt: What is Visual Perception?
Well, in short, visual perception is the ability to perceive information and image with elements of light via the human eye.
The eye is a very complicated visual system in the human body, as can be seen in the picture below.
When the human eye perceives an image in the eyeball, it is reflected on the cornea of the eye. Then, the image moves through the pupil, where the lens project the image on the retina. After the image is shown on the retina, the information is transmitted via the optical nerve to the brain. This all happens in the blink of an eye (how appropriate, this expression!)
With the visual possibilities of humans, it is possible to test all kinds of little tricks for the eye. There are number of optical illusions where the eye (and therefore the brain) perceives an image differently than it really is. This is because the people perceive components as wholes or groups and then the brain makes his own conclusion to what it sees. In the image I showed you last time was a nice lady walking with the view of the village on the background, but I'll bet a number of you readers only saw an enormous face in the image!
Next blog I will continue talking about the magificent world of Cognitive Science. For now, I have only one thing to see:
Don't let your eyes trick you!
