Visual Processing

Blind Spot

Where the optic nerve exits the eye

Lens Accommodation

The way the lens curves to focus on objects at different distances

Trichromatic Theory of Color

According to this theory any color we see is some form of combination of these primary color of Blue, Red, and Green 

Opponent- Process Theory 

This suggest that the visual system processes color in opposing pairs blue- yellow, and black-white. When one color cell is activated, another is inhibits. When these cells are exhaust themselves this creates after images. 

Conea

It is responsible for fine detail and color, focused mostly in the center of the retina in an area referred to as the fovea.

Rods

They are mainly responsible for peripheral vision and are more sensitive to light, giving us better vision in low-light situations.

How do Rods and cones send Neurochemical signals

Through bipolar and ganglion cells to the thalamus via optic nerve 

Light/Dark Adaptation

Is when our pupils change size to adapt to dark and bright environments

Feature Receptors

They are located in the occidental love relay information on shape,edges,angles,etc

Perceptual Constancy

Feature receptors allow to maintain recognition of things from different angles and colors

Parallel Processing

The processing of all these factors( speed, distance,texture, color, etc)

Nearsightedness

Too much curvature of the cornea and/or leans focuses an image in front of the retina so nearby objects are seen more clearly than distant objects

Farsightedness 

Too little curvature of the cornea and/or leans focuses the image behind the retina so distant objects are seen more clearly than nearby objects 

Astigmatism

an irregularity in the shape of the cornea and/or the leans:distorts and blurs the image at the retina.

Synthesia

When your Brian routes sensory information through multiple unrelated sense,causing you to experience more than one sense simultaneously. Ex tasting words or linking colors to numbers and letters

Relative Clarity 

Object further back appear blurrier 

Relative Size

Objects further back appear smaller

Texture Gradient

Objects further back appear smoother

Linear perspective

Parallel lines appear to converge in the distance

Interposition 

Objects that overlap create the appearance of some being further away 

Retinal Disparity

Slight difference in the images received by the two eyes due to their slightly different position on the fave 

Convergence

The way that eyes move inward to focus on closer objects

Figure-Ground

Tendency to perceive objects( the figure) as district from their surrounding (the ground)

Closure

Tendency to fill in gaps to perceive a complete objects

Proximity

When objects are close together we perceive them as groups

similarity

When objects appear like we perceive them in groups
