Question

9. Explain, in detail, the process of vision.

Answer 1

9-The process of vision begins as lights  passes through cornea and lens, the two combined produce a  image of the visual stimuli on the retina. The eye resembes a camera, since the image on retina is reversed: The information located in the retina  composed of electrical signals travels through the optic nerve to differents paths in the brain, in a tremendous speed we experience sight.

10- Proximity: The principle of proximity states objects that are close to one another appear to form a group. The eye tends to interpret them as a group if they are close.

Similarity- The principle of similarity refers to, all else being equal, the human perception lends itself to seeing stimuli that physically resemble each other as part of the same object. We tend to see a distinction between adjacent and objects that are overlapping based on a given visual texture and resemblance.  

Continuity: When there is an intersection between two or more objects, Human mind has a  tendency to perceive objects as a single continuos object.

Clousure: This refers to the mind’s tendency to see complete figures or forms even if a picture is incomplete, even when there are some missing lines.
