certain limitations that can affect our perception of the world. Here are some common
limitations:
1) Sensory Range
Our senses are limited in terms of the range of stimuli they can detect. Each of our
senses, such as vision, hearing, taste, touch, and smell, is specialized to detect certain
types of stimuli within a specific range.
Our senses evolved to detect stimuli that are relevant to our survival and everyday
experiences. While they are incredibly useful, it’s important to remember that there are
many stimuli in the world that fall outside the range of our sensory perception.
(1) Vision
Human vision refers to the sense of sight that allows individuals to perceive and
interpret the surrounding visual environment. It is considered one of the most important
senses, as it provides a significant amount of information about the world around us.
Our ability to see enables us to perceive the shape, color, size, and movement of
objects. It allows us to navigate our environment, recognize faces, read, and interpret
visual symbols and signs. Vision also plays a crucial role in providing spatial awareness
and depth perception, which are essential for judging distances and interacting with
our surroundings. Furthermore, vision is closely linked to cognitive processes, such as
memory, attention, and problem-solving. We learn and understand a significant portion
of our surroundings through visual input.
The process of human vision involves the interaction between the eyes and the
brain. Here’s a simplified step-by-step overview:
a. Light enters the eyes through the cornea, a clear protective layer covering the
front of the eye.
b. The light then passes through the pupil, the adjustable opening in the center of
the iris, which controls the amount of light entering the eye.
c. The light further converges through the lens, which adjusts its shape to focus the
light onto the retina at the back of the eye.
d. The retina contains specialized cells called photoreceptors (rods and cones) that
detect the light and convert it into electrical signals.
e. These electrical signals are transmitted through the optic nerve, a bundle of nerve
fibers, to the brain.
f. In the brain’s visual cortex, these electrical signals are processed and interpreted,
resulting in the perception of visual images, colors, shapes, and depth.
Some research shows that 20% of what is available to be seen is lost or distorted
