Looking for articles that answer your questions on sensation and perception? This one should do it!
I will discuss some other factors that affect sensation and perception
in the next few posts.

Perception is a part of the cognitive process that helps us
make sense of our environment so that we can make decisions in our own, unique
ways through the inputs we select and prioritise; how we organise the selected
inputs and our personal interpretations of the information we gather from the
way we have arranged the inputs we have selected.
Human perception, thus, is the subjective or personal result
of sensation. It is the dynamic "knowing" about the direct sensation
"in your mind." Perception is subjective because it occurs within you.
It is dynamic because can change from moment to moment and situation to
situation. Depending on the moment, the mood and other factors, you may
perceive the same sensations differently at various instances.
To explain the perceptual process in more detail, let me
take a personal example:
As I stand and deliver a lecture to my class, your
consciousness makes you aware of sitting there listening to me, the external
other. As I speak, you hear the sensation of sound, feel the discomfort of your
chair, smell the cold air blowing from the air-conditioner mixed with other
people smells, see me standing, a colleague sleeping, another texting, the LCD PowerPoint
display, the cloudless blue sky, workers on the terrace next door and so on...
These sensations are available to the entire class but its
individual members "perceive" different things. One student chooses
to select a whispered comment from his friend over my words; another
concentrates on the pain the chair causes her back instead of my lecture; a
third compares the colour of my sari with the blue sky while you listen closely
to what I'm trying to get across.
Each student will have a different perception of the class
depending on her selection of sensations to prioritise, the way she organises
the sensations she selects and the interpretations she derives from the
structures she has created in her mind.
Sensation is automatic. If my visual and aural mechanism
works, I cannot NOT see or hear. So as I stand in class, I can see and hear and
feel and smell all that is available within the range of my sensory abilities.
At the end of my lecture, though, if you asked me what I saw, I would only be
able to identify those things that I actually "looked" at--i.e.,
those objects I chose to select and
organise and interpret in my mind. Therefore, my perception of the class and
yours would be very different because you and I would probably be selecting
different objects to "look at" depending on our individual
filters--our own personalities, our interests, our knowledge-set, our previous
experiences, our moods, emotions, attitudes etc.
A policeman friend once told me that one of his worst
nightmares was to investigate a public incident of which there were many
different witnesses because witness accounts of the same event are sure to
differ wildly and even contradict each other because of individual perceptions
(which each witness would be sure was 100% correct!)
It should be obvious to you now that perception is not--and
cannot ever be--reality and that just as Gerbner's General Model shows, the
real event E ceases to exist once it has been perceived and become E1.
The degree of similarity or distance of E1 to E (or the perceived
event to the real event) depends on certain factors. Gerbner suggests
selection, context and availability as factors controlling the perceptual
dimension.
