Time perception is not one of our greatest skills.
Perception Principles
Perception is active, not passive. We attack you incoming data as it arrives. We don’t wait. We use rules to help us process things more quickly. Perception -principles are primarily simple, fast, and efficient rules. They include sorting like items together and scariest things first. Simple rules are combined into complex ways of locating objects, identifying friends and avoiding enemies.
Visual Disorders
Vision is a complicated system. There are a lot of components and processes. Sometimes things go wrong. Here are some of the major examples of visual disorders. Some can be corrected but many can’t. Once vision is gone there is little that can be done.
Nystagmus is a disorder which impairs vision by causing involuntary eye movements. The eyes move rapidly back and forth. Some believe it is an autofocus feature gone wrong. The eyes are searching for focus. Many current models blame the connection between the eyes and the semicircular canals of the inner ear. When looking at a distant object, you can turn your head but maintain your gaze. To accomplish this tasks, signals are exchanged between the eyes and the semicircular canals. When the connection works well, you can maintain a fixed gaze and turn your head without getting dizzy. When something is wrong with the signaling from the semicircular canals, the eyes shift rapidly. In humans, nystagmus is congenital in albinos, can develop in infancy from disease, or comes on in adulthood as a result of drug or alcohol addiction.
Human Eye
The human eye is a wonder. It transducers light into patterns of neural activity.Then we use those neural signals to help us move around and understand our environment.
Color Vision
The earliest theories of vision were egocentric. They thought rays came out of the eyes, reflected off an object (or captured it) and returned it the eye. The images were conveyed to the soul. Thought was believed to be the manipulation of images. There was no imageless thought.
Light & Eyes
What Is Light
Light and eyes go together. They are in that category of useful mysteries. It is not alone. We use the warmth of the campfire without knowing much about thermodynamics . We drink water without knowing much about hydration. And for many of us, we dress ourselves in clothes without knowing much about style.
