Introduction to Sensation and Perception
Try this. Stop focusing on the computer screen and pay
attention to any of the other things that are happening right
now. Do you hear any noises that you hadn't heard before? Do
you hear birds singing, car sounds, airplanes, or the sound of
your breathing? There are stimuli around us all the time, and we
are always selecting, consciously or unconsciously, what to pay
attention to or what to prioritize for processing. However,
remember that we can only attend to stimuli that we have the
ability to process. We have to possess the proper body parts and
specially designed receptors to be able to receive the stimuli.
Not having the proper body parts is like trying to catch a fish
for dinner without a net or a hook and bait. Sensory processing
is like fishing for food—if we do not have appropriate tools, we
cannot catch a fish. As you probably know, each sensory
modality has specific hooks or receptors that enable us to detect
stimuli. For example, our eyes have photoreceptors, and our
ears have auditory receptors called hair cells. These receptors
are a key component because they transduce physical and
chemical stimuli, which means that they change the stimuli into
electrical currents so the brain can process the information. If
there is no problem with receiving and transducing a stimulus,
that stimulus (which is now represented by electrical impulses)
must be transmitted and processed throughout the brain. It is in
the brain, between primary sensory and higher-level processing,
that perception occurs. Recognition and categorization are part
of perception, and this is where the perspectives and views of
human beings significantly diverge. People significantly diverge
in their perceptual processes.

and volunteer groups, or non-governmental organizations);
· Response efforts (local, state, and federal governments; and
volunteer groups, or non-governmental organizations);
· Recovery efforts (local, state, and federal governments; and
volunteer groups, or non-governmental organizations);
· Communication for response efforts and to affected
populations; and

Sensation occurs at the beginning of a sensory system, and
perception involves interpretation and memory that surrounds
the brain (Goldstein & Brockmole, 2016). There are basically
seven steps to perceptual process: Stimulus in the environment,
light is reflected, receptor process, neural processing,
perception, recognition and then action (Goldstein &
Brockmole, 2016). Sensation activates our senses, and
perception follows sensation, and is the understanding of the
sensations (https://explorable.com>sensations-and-perception).
Perception always leads to action, and is constantly changing,
for example, if I constantly move my body and eye close to a
rose bush, then I will continue to have new images or
transformations (Goldstein & Brockmole, 2016). As long as one

3. has the ability to to touch, taste, or feel pain, sensation and
perception exists, although our perceptions are built from
sensations, but not all sensations result in perception, al though
they both work together, we don't receive stimuli that remain
relatively constant over prolonged periods of time, for example,
if I walked into a room and heard a clock ticking, after while,
after I start talking on my phone, I would no longer hear the
ticking of the clock, this is known as sensory adaption
(https://course.lumenlearning.com).
Perceptions helps us to understand our world, but it can also be
faulty, because it can allow to think things that are not true.
There are also things such as beliefs, values, prejudices,
culture, and life experiences, that affects perception, an there
are things such as attention and motivation, that affects
sensation (https://course.lumenlearning.com).

Perception is the process by which people become aware of
objects and events in the outer environment. Stimulation,
organization, interpretation-evaluation, memory, and recall are
the five stages of perception. People who researched perception
did so because they were curious about themselves and the
world, not because they were trying to solve a problem. (
Goldstein, E. B., & Brockmole, J.)(2016). (pg5)
The process begins with a stimulus in the environment, light is
reflected and focused, the Receptor process, Neural processing,
perception, recognition, action.

4. These seven processes, plus "knowledge" within a person's
brain, outline the major events that occur between the time a
person looks at a stimulus in the environment (in this case, a
tree) and perceives, acknowledges, and acts on it. (McCartney,
1970) (pg5)
· (Step 1). It is called distal because it is “distant”—out there
in the environment.
· (Step 2). The reflection of light from the tree introduces one
of the central principles of perception, the principle of
transformation, which states that stimuli and re- responses
created by stimuli are transformed, or changed, between the
distal stimulus and perception.
· (pg22-23)
· Step 3 of the perceptual process. Receptor processes include
transduction (the transformation of light energy into electrical
energy) and the shaping of perception by the properties of
visual pigments in the receptor’s outer segments. The result is
an electrical representation of the tree
· Step 4 of the perceptual process. Neural processing involves
interactions between the electrical signals traveling in networks
of neurons early in the system, in the retina; later, on the
pathway to the brain; and finally, within the brain.
(pg22-24)
· The person perceives the tree (Step 5) and recognizes it
· (Step 6). We can distinguish between perception, which is
conscious awareness of the tree, and recognition, which is
placing an object in a category, such as “tree,” that gives it
meaning, by considering the case of Dr. P., a patient described
by neurologist Oliver Sacks (1985).
· The final behavioral response is action (Step 7), which
involves motor activities. For example, the person might decide
to walk toward the tree, have a picnic under it, or climb it.
(Cengage, 2015), (pg. 21-24)
Sensation and perception are two distinct but closely connected
processes. Our sensory receptors provide us with information

5. about the physical world, and perception is the process through
which the brain picks, organizes, and interprets this
information. In other words, the physiological basis of
perception is the senses. Because each person's brain interprets
stimuli differently based on their learning, memory, emotions,
and expectations, perception of the same senses might change
from person to person. The chemical changes in the cells that
line the back of the eye are caused by the light that enters the
eye. The central nervous system receives messages from these
cells in the form of action potentials. The way sensory
information is organized, analyzed, and consciously experienced
is referred to as perception. Bottom-up and top-down processes
are both involved in perception. Perception begins when the
brain accepts incoming information. It does not always imply a
definite and obvious point where feeling finishes and perception
begins, nor does it imply that sensation and perception occur in
the same location for everyone. (Psychology Press, 2008) (pg.
8)
My question is how can perception affect people's behavior if
every individual perceives the situation differently?
