perceptual processing Quotes

I think seeing happens partly through the eyes, but not entirely.

The organ of perception acts more readily than judgment.

Eighty percent of the information we receive comes through our eyes. And if you compare light energy to musical scales, it would only be one octave that the naked eye can see, which is right in the middle.

Memory demands an image.

Cognitive neuroscience is entering an exciting era in which new technologies and ideas are making it possible to study the neural basis of cognition, perception, memory and emotion at the level of networks of interacting neurons, the level at which we believe many of the important operations of the brain take place.

When a sound can replace an image, cut the image or neutralize it. The ear goes more towards the within, the eye towards the outer.

The eye and brain are not like a fax machine, nor are there little people looking at the images coming in.

The eye obeys exactly the action of the mind.

The less the mind understands and the more things it perceives, the greater its power of feigning is; and the more things it understands, the more that power is diminished.

We do not hear what we hear..., only what we remember.

I'm repledging myself to human-scale values. As a fiction writer, the best data comes through the senses and is then processed through many revisions. We have to learn to be intelligent assessors of the data coming in to us and what it's doing to our mental process.

If the eyes are open and there is light, seeing occurs; the stimulus is but a condition of the fulfillment of the proper function of the organ, not an outside interruption. To some extent, then, all direction or control is a guiding of activity to its own end; it is an assistance in doing fully what some organ is already tending to do.

The gist of the matter is this: Every impression that comes in from without, be it a sentence which we hear, an object of vision, or an effluvium which assails our nose, no sooner enters our consciousness than it is drafted off in some determinate direction or other, making connection with the other materials already there, and finally producing what we call our reaction. The particular connections it strikes into are determined by our past experiences and the 'associations' of the present sort of impression with them.

It is so wonderful to our neurologists that a man can see without his eyes, that it does not occur to them that is just as wonderful that he should see with them; and that is ever the difference between the wise and the unwise: the latter wonders at what is unusual, the wise man wonders at the usual.

Obviously, the faster we process information, the more rich and complex our models or glosses - our reality-tunnels - will become.

Pictures, propagated by motion along the fibers of the optic nerves in the brain, are the cause of vision.

Every act of perception has an emotional coloring.

The eye transmits its own image through the air to all the objects which face it, and also receives them on its own surface, whence the "sensus communis" takes them and considers them.

So how, children, does the brain, which lives without a spark of light, build for us a world full of light?

He began to search among the infinite series of impressions which time had laid down, leaf upon leaf, fold upon fold softly, incessantly upon his brain; among scents, sounds; voices, harsh, hollow, sweet; and lights passing, and brooms tapping; and the wash and hush of the sea.

Sometimes you cannot help what you hear, you cannot help what you see.

I think you have to use your eyes as well as your emotion, and one without the other just doesn't work

As for the clarity of the 48 frames, I've heard people say that it looks odd, it's too demanding, there's too much information, you don't know where to look.

In the traditionally taught view of perception, data from the sensorium pours into the brain, works its way up the sensory hierarchy, and makes itself seen, heard, smelled, tasted, felt - "perceived." But a closer examination of the data suggests this is incorrect. The brain is properly thought of as a mostly closed system that runs on its own internally generated activity.
