Art of Perception
The concept of perception for humans
has proven to be a very important topic. A whole branch of
psychology started from this concept. It was noted by earlier
psychologists that everyone's view of reality was fundamentally unique to
them. It was proposed that objects had no inherent meaning in and of
themselves, but the viewer of that object who attached a meaning to the
object. This act of attaching meaning to a given stimulus in our own
particular way, is what is known as perception to psychologists. It
is this uniqueness that inspired a third branch of psychology called
phenomenology. That is to say that there is really no way for any of
us to truly experience what another person is experiencing. We can
only have a representation of what their experience is based on our
interpretation of what we see and have seen in our lives.
One of the most profound beliefs
centers on how information is processed by people. In
phenomenological approaches there is a supposition of a figure-ground
cognitive activity. That is to say that given the bombardment of
sensory input that hits us during all of our waking moments, there is a
"figure" that emerges to focus our attention on. For example, as you
are reading this sentence, you are probably not even aware of ambient
sounds, fans, air conditioners, heaters, clocks, etc., of your house,
office, or computer lab until I just mentioned them to you.
Hopefully, my words are the figure and the all the rest fades to (back)
"ground." There is also the phenomena of "closure" playing a
uniquely human role as well. We have sense-making machines between
our ears. Our brains actually work as probability wizards in that
given incomplete information on virtually all occasions, we have a large
degree of certainty about our conclusions. Our brains fill in the
missing parts of information in order to make sense of the world. It
is the only way we could live efficiently.

Bottom/Up:
-
This style of Processing is often also referred to
as "Feature Analysis." A bottom/up person is one who naturally
begins to notice details within a situation or problem before
anything is processed. They see all of the bricks first and
then realize that there is a wall there. For this person there
is a great value put on the collecting of and accurate storing of
all the details. They might only feel that they truly know a
topic when they have achieved a great degree of mastery of the
details. Now, knowing something about the "big picture" is
very difficult for these people. They tend to have a very hard
time with drawing conclusions as to what might be generally
happening in a situation. In other words, they might be able
to tell you the names of everyone at a party but not know who is
involved with whom.
-
These kinds of students want details from you.
They rather expect you to be the expert that they have been longing
for their entire academic careers. They can be rather
challenging to you in that you may ask them for the theme of a
story, or a conclusion to a lab, or a theory at play and a bottom/up
student will tell you all of the details in their head, but not
answer your more interpretive question.
-
Top/Down:
-
This processing style is the exact opposite of bottom/up
sometimes referred to as "Pattern Recognition." These people have
a natural proclivity toward seeing the "big picture" while details
simply get by them. They will walk into a party and immediately
get a feel for who is involved with whom. This top/down
type of person won't see the need to delve into the details. For
them it becomes a question of "What's the point? I get right now!"
Details are a waste of time. So for these types of processors the
pattern (big picture) is virtually instantaneous while the details are
very challenging.
-
The teacher might ask them a thematic/interpretive type
of question and they will have a good answer. But then you ask
them for supporting details and they are very likely to just roll their
eyes, shrug, tell you something like, "whatever." These students
want to talk about the larger issues in the subject area. They
want you to make them think about further implications.
