A&O – DEEP – PERCEPTION: VISION

ART & ORGANISM

DEEP ETHOLOGY

PERCEPTION 

VISION

 

The path from the outer world to its inner representation is the beginning of perception:  Sensation is transformed to  perception is transformed to conception with a complicated array of congenital and acquired influences at each stage.  And certainly, the sense organs themselves are never as complete as they seem in conscious awareness.   The balance between too much information and too little has evolved over countless generations.     

In A&O, the emphasis is on PERCEPTION and while all senses are involved in all experiences, in our species vision is of immense importance (even though in specific cases, individuals without vision can cope with the environments they encounter quite well, especially if the lack of sight occurs early in an individual’s development)

IT IS INTERESTING THAT THE ACTUAL FIELD OF CLEAR VISION IS A FRACTION OF WHAT YOUR EYE SEES.

“The fovea is employed for accurate vision in the direction where it is pointed. It comprises less than 1% of retinal size but takes up over 50% of the visual cortex in the brain.[12] The fovea sees only the central two degrees of the visual field, (approximately twice the width of your thumbnail at arm’s length).[13][14] If an object is large and thus covers a large angle, the eyes must constantly shift their gaze to subsequently bring different portions of the image into the fovea (as in reading). Foveal fixation is also considered as a overt form of attention which allows to focus sensory processing resources on the most relevant sources of information.[15][16][17][18] Also, foveated vision may allow speeding up learning of specific visual tasks by disregarding not relevant context and focusing on the relevant information only with lower dimensionality.[19][20] …Since the fovea does not have rods, it is not sensitive to dim lighting.
