Consecutive Vision
Consecutive vision was used during the Renaissance. Consecutive vision is where the entire painting has the same degree of focal clarity.This means that anywhere you look in the picture, the same amount of detail will be shown, even in the background.
Simultaneous/Biocular vision
Simultaneous vision is where one point is in focus, and it goes out of focus over 360 degrees. The further away from the point of focus, the more out of focus it gets. Simultaneous vision mimics the way people look at the world, with two eyes focused on the one point, and the rest kind of blurring out.
Monocular Vision
Monocular Vision is where everything on the same plane is in focus. Monocular vision was inspird by the invention of photography, and mimics the way a camera views the world.
Gestalt Vision
In Gestalt vision the unimportant things are rendered, rather than the important things. An example of Gestalt vision would, if you were rendering a window, be to draw the straight lines and leave out the corners, or draw the corners and leave out the straight lines (as seen in this example). By only drawing the unimportant things, you are actually drawing attention to what is not there, leaving the mind to fill in the blanks.
Cone (foveal/photopic) vision
These terms refer to our daylight vision where we look through the centre of our eyes and see colour. The name comes from the cones in our eyes that we use to see colour. This would look like a 'normal' colour painting
Rod (peripheral/scotopic) vision
Scotopic vision is the monochromatic vision of the eye in dim light. Since cone cells are nonfunctional in low light, scotopic vision is produced exclusively through rod cells so therefore there is no colour perception.
Hagen Haltern, A Chair in Peripheral Vision
Mesopic vision
Mesopic vision occurs in intermediate lighting conditions … and is effectively a combination of scotopic and photopicvision. This however gives inaccurate visual acuity and colour discrimination.

Penti Mento
Penti Mento is where traces from a previous working can be seen in a painting. These traces should not be from an entirely different painting that the artist has painted over, but be the outlines of a different pose or underdrawing. The word derives from an italian word meaning repent.
"The term has sometimes been used in a modern sense to describe the appearance of the sides of buildings with painted advertising. Often they are painted over with newer ads and the paint wears away to reveal the older layers."

Gestalt - Laws of Organisation
Proximity—elements tend to be grouped together according to their nearness
Similarity—items similar in some respect tend to be grouped together
Closure—items are grouped together if they tend to complete some entity
Simplicity—items will be organized into simple figures according to symmetry, regularity, and smoothness.

Scanning
Scanning also takes time into account in the picture. Generally, scanning is multiple images forming a cohesive whole that show the passage of time.
