Hello fellow psych 3120 cog. psych peoples. I am taking the modes of =
learning and hope this is not too late to count for the first week; if =
it is I guess this is week 2 comments/questions/answers!
Anyway, I am impressed with the posts so far and here I'll add my two =
cents and quote some other posts, so this may be a long post, and =
unfortunately some of the quotes will look odd because of how I received =
them (with a lot of =3DA0's and just =3D signs.) Perhaps I'm going =
over-board but I really liked these posts and am compelled to comment on =
them.
"In class today Dr. Strayer defined perception as "the process of =
organizing
and interpreting sensory information to give it meaning". Do you =20
think there are more similarities or more differences between this =20
cognitive definition of perception and the way the word is used =20
colloquially? Consider for instance if you were to get in an argument =20
with someone. You might say, "My perception of the situation is that =20
you are at fault". How is use of the word similar to the cognitive =20
definition? How is it different?
-Ann"
MY COMMENT/ANSWER: I think there are more similarities than differences =
between the two uses of the word. The cognitive definition is probably =
not the answer you would receive if you were to ask someone what =
"perception" means; they might say something like "the way I see =
things." But even that hypothetical answer derives from the cognitive =
definition and supports it. The common use of the word transcends the =
cog. definition of the word; like it is a foregone conclusion. When =
using the word perception it is assumed that one has organized and =
interpreted sensory information, given it meaning (using the sensory =
information and memory), reached a conclusion and are in the act of =
expressing said perception. However this brings me to a question does =
the cog. science definition include an individuals past experiences and =
memory with the "process"? I almost assumed it did with the "...to give =
it meaning," portion. How can you give it meaning within context without =
prior experience and memory on any given perception, or at least a place =
to start? Is this question making sense? Does anyone have an answer for =
this? Perhaps I'm thinking too deep into this one little sentence...
The difference between this cognitive definition and the colloquially =
usage of the word is the cognitive definition refers to the processes =
used, which arguably can be generalized as being used by ALL people (and =
which is what cognitive scientists want to prove.) The colloquially use =
of the word is more individualized in the sense that it usually refers =
to a single person's perception of events, which differs from person to =
person, while ignoring the processes by which any particular event is =
perceived. Such as the example used by Ann.

MY COMMENT/ANSWER: I find this trick very interesting. From the lectures =
(I haven't read ch.3) it seemed to me that the visual system fills in =
color not arbitrarily but based on experience. I would think the =
prosecutor could retort by saying the eye-witness had actually looked =
directly at the car at some point, without realizing that he/she had, =
saw the color and subsequently when the vehicle left the scene and the =
witness saw it out of the corner of their eye whichever portion of the =
visual system V1-5 consequently filled in the correct color. Also from =
my sense & perception class I know that cones ARE present elsewhere =
within the retina besides the fovea, albeit very very small amounts of =
them, which decrease as one travels farther away from the fovea (as =
illustrated in one of the slides last Thursday, if you look on the graph =
the cone curve never reaches the bottom.)

MY COMMENT/ANSWER: Wow this is so cool!! Thank you so much for sharing =
the fruits of your research! Frankly speaking I won't EVER get LASIK =
surgery just because in my head it's a freakin laser beam aimed directly =
at my eye, and laser beams as we all know are very destructive; reason =
and knowledge sometimes just go right out the window. If this new =
technology works and they can make it permanent I'd so do it (I wear =
glasses.)=20
"First a class question:
When are the mode postings due? I hope this isn't late but it is the =
=3D
last day of the week. =3D20
=3D20
I am curious about retinal images. In chapter one, it states that "it =
=3D
doesn't matter whether the top of the world is represented in the top or =
=3D
bottom..." My curiousity stems from the ideat that if it doesn't matter =
=3D
then why does an image become upside down on the retina? And then how =
=3D
does it turn it right side up so that it what we preceive. Is this done =
=3D
by the retina or our brain? I am sure the answer will come about during =
=3D
the course.
=3D20
Shonda Buckland"
MY COMMENT/ANSWER: The image is upside down on the retina because of how =
light is reflected off of objects into the eye and onto our retina. =
Things below our eye reflect light upward toward our eye thus hitting =
the upper portion of the retina, vice-versa for things above our eye. =
And same for things to the sides and all the degrees in between. So =
basically it is upside on our retina because of physics. Also the image =
is turned right-side up by the brain (if I remember correctly)...I can't =
recall which module. But what if the world that we perceptually see IS =
actually upside down? Would it really matter as long as we can correctly =
maneuver within the environment? I think this is what the book was =
trying to get us to think about. Also the studies mentioned in class =
about the goggles that turn the world upside down.
"ok so i am not sure if this is how i am supposed to do this so i guess =
=3D
we will see if it works. lets just say i dont do too well with =3D
computers... Anyways i thought that all of the previous posts have been =
=3D
very interesting. also the lecture in class has really caught my =3D
interest. What really made me think was the color spectrum in which we =
=3D
are able to see different colors. I didnt know that animals saw =3D
different colors and wavelengths. the whole concept of vision is very =
=3D
intreaging and seems very compicated. Every since i was little i had a =
=3D
specific question about vision and my teachers never quite answered it =
=3D
for me. my question is: How do we know all humans see color the same? i =
=3D
realize that colors give off certain wavelengths and that we know the =
=3D
wavelengths for each color but how do we know that the color we actually =
=3D
see is the same. what if my pink is another persons blue? but for them =
=3D
they have been taught to call that color pink... this might be kind of =
=3D
confusing i guess... but i guess im just wondering if everyone sees the =
=3D
exact same colors or if everyone sees differently and calls them by what =
=3D
they are taught....i hope that makes sense..."
-not sure who posted this
MY COMMENT/ANSWER: I too have pondered this question, and it does make =
complete sense and is quite intriguing. Did you know that light actually =
has no intrinsic color, our brain (and those of other creatures) GIVE it =
color. Anyway, back to the question I personally believe that no two =
people see color in exactly the same way, but in reality it really =
doesn't matter nor is it provable. As we are taught color a person =
points to something and says this is red and what we see we label red, =
not what they are seeing. Perhaps red actually looks blue to me but =
because it consistently is the same color no matter the label, I =
correctly label it red every-time because it is the label I have learned =
to associate with the color I am seeing. I hope that makes sense.
Ok, well that was a lot. Sorry for such a long post. Thanks for reading =
=3D) !! I too find this stuff fascinating. On a related vein I noticed =
many of you expressed great interest in the visual system and how it =
works. For those I STRONGLY urge you to take Psych 3150 'Sensation & =
Perception' 2/3's if not more of this course is dedicated to the visual =
system, how it physically works (as in the eye, retina, neural pathways =
etc.) but goes much more in depth into the cognitive processes and =
strategies used by the brain to see what we see, and how what we see is =
not always a reflection of reality. I took it last spring with Dr. Sarah =
Creem-Regehr who I found to be an excellent professor. (She also needs =
RA's for those interested!)

While reading the chapter I learned an interesting theory. The theory
was developed by Biederman, stating that object recognition is done by
matching visual stimuli with 36 different shapes called geons. These
geons, shaped like bricks, cylinders, etc. can be combined to form
more complex shapes. The book was unclear in describing how Biederman
concluded that each geon was important to visual perception, however
an experiment was described to show the importance of geons generally.
Biederman took drawings of common objects and removed the
intersections between the different lines in the drawings. Even though
the pictures were altered, certain geon shapes were left in the
drawings. People recognized the objects 90 percent of the time when
the vertices were intact. When the vertices were removed they
recognized the shapes only 30 percent of the time. This showed how
important line intersections are in recognizing shapes and objects.
This is consistent with Biederman's theories. However, many objects
don't contain geon shapes, and the theory doesn't apply to these
specific objects. This was a very interesting theory, despite it's
inconsistencies.

X-rays use radiation. This is why when you go to the dentist they give you
that led vest to put over your chest. It's been know for a while that

The word pragnanz is a German term that basically means "good figure". The =
Gestalt law of pragnanz is sometimes referred to as the law of good figure =
or the law of simplicity. My understanding is that it describes how our per=
ceptual system tends to see objects in the simplest form possible. This is =
similar to the liklihood principle discussed in the book on p 73. For examp=
le=2C the slide shown in class with the overlapping circles could be a bunc=
h of separate and more complicated shapes=2C but it is more likely that the=
y are circles and a more simple form to look at=2C so we tend to perceive t=
hem that way. I don=3Bt know if that helps clarify but hopefully a bit.
This week=2C I found the importance of top-down processing and the ambiguou=
s figures shown in class very interesting. I had seen some before but most =
of them were new to me. Dr Strayer mentioned that if we saw one of the pic=
tures again in one or two years=2C w would be more likely to recognize the =
figures because we had been exposed to them before. This left me wonderin w=
hat role our memory plays into it. If we don't consciously remember seeing=
the picture before even if we had=2C would the prior experience still make=
it easier to recognize? Also=2C is there any reason that some people recog=
nize the ambiguous figure more easily than others=2C regardless of whether =
they had seen them before?

>=3B While reading the chapter I learned an interesting=
theory. The theory
>=3B was developed by Biederman=2C stating that =
object recognition is done by
>=3B matching visual stimuli with 36 d=
ifferent shapes called geons. These
>=3B geons=2C shaped like bricks=
=2C cylinders=2C etc. can be combined to form
>=3B more complex shap=
es. The book was unclear in describing how Biederman
>=3B concluded =
that each geon was important to visual perception=2C however
>=3B an=
experiment was described to show the importance of geons generally.
&=
gt=3B Biederman took drawings of common objects and removed the
>=3B=
intersections between the different lines in the drawings. Even though >=3B the pictures were altered=2C certain geon shapes were left in the =
>=3B drawings. People recognized the objects 90 percent of the time =
when
>=3B the vertices were intact. When the vertices were removed t=
hey
>=3B recognized the shapes only 30 percent of the time. This sho=
wed how
>=3B important line intersections are in recognizing shapes =
and objects.
>=3B This is consistent with Biederman's theories. Howe=
ver=2C many objects
>=3B don't contain geon shapes=2C and the theory=
doesn't apply to these
>=3B specific objects. This was a very inter=
esting theory=2C despite it's
>=3B inconsistencies.

I, too, was very intrigued by the ambiguous figures that we viewed in
class. I know I have seen many of those pictures before and was
therefore able to see both the figures in each picture quickly. I
remember the first time(years ago) I viewed the old lady/young lady
picture and I could only see the old lady and once the young lady was
pointed out to me it took concentrate to switch my perception/view of
the picture from old lady to young lady and visa-versa. But now when I
view this same picture I can see both interchangeably quite easily. The
dalamation I had trouble viewing though. Even when Dr. Strayer pointed
it out, I could grasp where the body was but could not see the head or
tail ends. Once the one student raised his hand and pointed out that he
turned it around and then him and the girl next to him could view it, I
tried that technique and sure enough I could see the dalamation as clear
as ever! Why was this so? I also wonder why some people can see the
figures while others cannot not.? And lastly. Is there a difference
between how people perceive things based on which lady or picture they
view first. Like when I would see the old lady but not the young lady???

Subject: [Psych3120] week 2- law of pragnanz and ambiguous figures
=
The word pragnanz is a German term that basically means "good figure".
The Gestalt law of pragnanz is sometimes referred to as the law of good
figure or the law of simplicity. My understanding is that it describes
how our perceptual system tends to see objects in the simplest form
possible. This is similar to the liklihood principle discussed in the
book on p 73. For example, the slide shown in class with the overlapping
circles could be a bunch of separate and more complicated shapes, but it
is more likely that they are circles and a more simple form to look at,
so we tend to perceive them that way. I don;t know if that helps clarify
but hopefully a bit.
This week, I found the importance of top-down processing and the
ambiguous figures shown in class very interesting. I had seen some
before but most of them were new to me. Dr Strayer mentioned that if we
saw one of the pictures again in one or two years, w would be more
likely to recognize the figures because we had been exposed to them
before. This left me wonderin what role our memory plays into it. If we
don't consciously remember seeing the picture before even if we had,
would the prior experience still make it easier to recognize? Also, is
there any reason that some people recognize the ambiguous figure more
easily than others, regardless of whether they had seen them before?

I, too, was very intrigued by the
ambiguous figures that we viewed in class. I know I have seen many of those=
pictures before and was therefore able to see both the figures in each pict=
ure
quickly. I remember the first time(years ago) I viewed the old lady/young l=
ady
picture and I could only see the old lady and once the young lady was point=
ed
out to me it took concentrate to switch my perception/view of the picture f=
rom
old lady to young lady and visa-versa. But now when I view this same pictur=
e I
can see both interchangeably quite easily. The dalamation I had trouble vie=
wing
though. Even when Dr. Strayer pointed it out, I could grasp where the body =
was
but could not see the head or tail ends. Once the one student raised his ha=
nd
and pointed out that he turned it around and then him and the girl next to =
him
could view it, I tried that technique and sure enough I could see the
dalamation as clear as ever! Why was this so? I also wonder why some people=
can
see the figures while others cannot not.? And lastly. Is there a difference=
between how people perceive things based on which lady or picture they view=
first. Like when I would see the old lady but not the young lady???

Subject: [Psych3120] week 2-=
law
of pragnanz and ambiguous figures
The word pragnanz is a German=
term
that basically means "good figure". The Gestalt law of pragnanz i=
s
sometimes referred to as the law of good figure or the law of simplicity. M=
y
understanding is that it describes how our perceptual system tends to see
objects in the simplest form possible. This is similar to the liklihood
principle discussed in the book on p 73. For example, the slide shown in cl=
ass
with the overlapping circles could be a bunch of separate and more complica=
ted
shapes, but it is more likely that they are circles and a more simple form =
to
look at, so we tend to perceive them that way. I don;t know if that helps
clarify but hopefully a bit.
This week, I found the importance of top-down processing and the ambiguous
figures shown in class very interesting. I had seen some before but most of=
them were new to me. Dr Strayer mentioned that if we saw one of the
pictures again in one or two years, w would be more likely to recognize the=
figures because we had been exposed to them before. This left me wonderin w=
hat
role our memory plays into it. If we don't consciously remember seein=
g
the picture before even if we had, would the prior experience still make it=
easier to recognize? Also, is there any reason that some people recognize t=
he
ambiguous figure more easily than others, regardless of whether they had se=
en
them before?
