Subject: [Psych3120] Prototypes
Message-ID: <25066113.1196470241508.JavaMail.root@elwamui-royal.atl.sa.earthlink.net>
The lecture on prototypes the other day was really interesting. The dog example was perfect for this, since dogs come in so many shapes and sizes, yet people, in general, are able to tell when something is a dog, even if they have never seen that species before. The same thing applies to telephones. There are so many different types of telephones, yet people are usually able to immediately identify a telephone as being a telephone. We really use prototypes in so much in perceiving things, like with staplers, speakers, printers, computers, cell phones (sorry, I'm sitting in an office right now and just looking around me, applying thoughts on prototypes to different objects in the room). We even use prototypes in discerning people, that is, in discerning ethnicity of different people. Different prototypical features of different racial groups generally lead to stereotypes, so I won't go into any specific features. In fact, prototypes, when applied to race, are generally called stereotypes. But we do use prototypical features to know where someone comes from. I also think these prototypes become more general when applied to groups other than our own. In my Social Psychology class we talked about how people can more easily discern differences amongst people of their own race than amongst people of another. For example, an American Indian would have more trouble seeing difference amongst European Americans than a European American would. I think this is because we tend to believe people outside of our own race are more of their prototype than they really are because we try to fit them into that prototype.
I'm also wondering something about prototypes. Are prototypes, as discussed in class, only applicable to visual representation? Or are they applicable to other senses? Do we form prototypes for hearing and tasting? It seems like we do, though I'm not sure if they would follow the same neural processes and thus be defined as the same thing by these processes. But if we can form prototypes of the senses, can we form prototypes of other, more complex forms of representation? Can we form prototypes of cultures? For example, are the stereotypes of different cultures, such as Americans enjoying violence but shying away from sex, is that a prototype also? Hhmmm.

Last week I was traveling early to work and noticed that the almost-full moon was just "setting" low on the western horizon. It was a burning red, and in spite of the fact that we learned about the entire phenomenon and how it works in Illusions and constancies a couple of months ago in the first unit, it still seemed that the moon was many times larger as it sunk there on the horizon. The point is, that even when one learns the science behind a phenomenon, it is still sometimes hard to "see" things differently than they appear. So, the moon still looked huge that morning to me, even though I tried to look through the illusion.

Recently I did several tasks we studied or did in class and I found my self using strategies depend on the tasks.
While I was doing a card game, concentration, I told what I need from the choices of color, number of card, and shape.
In another game, I had a hard time recalling the words group if I just tied to remenber as it appeared in order
compared to the one I tiried to make some semantic connections in order to remnber.
It was interesting to find what I was doing was one I just studied and I was doing problem solving at the same time.

If anyone gets a chance, grab a copy of National
Geographic magazine from November 2007. There is a
huge article on Memory, and on research of memory. The
article covers much of what we have been learning in
class, including info on H.M., but also covers two
other, current cases. One is in memory loss such as
H.M, in other words, hippocampal destruction, and no
new memories formed, but due to illness. And the other
case is a woman with a memory 'like a rolodex'. It
also goes into the history of memory, and the cultural
importance over time. For instance, before the age of
computers, memory for learning was much more vital
than it is today.
Here is a great quote that involves the neural
networks we are learning about now:
"What is a memory? The best that neuroscientists can
do for the moment is this: A memory is a stored
pattern of connections between neurons in the brain.
There are about a hundred billion of those neurons,
each of which can make perhaps 5,000 to 10,000
synaptic connections with other neurons, which makes a
total of about five hundred trillion to a thousand
trillion synapses in the average adult brain. By
comparison, there are only about 32 trillion bytes of
information in the entire Library of Congress's print
collection. Every sensation we remember, every thought
we think, alters the connections within that vast
network. Synapses are strengthened or weakened or
formed anew. Our physical substance changes. Indeed,
it is always changing, every moment, even as we
sleep."
(Joshua Foer, "Remember This", National Geographic,
November 2007, p.36)

as the ratio of information gained from information received so that a pers=

that a person's ability to do this is basically a problem solving ability.=
In any of these problem solving exercises, it requires you to make some i=

the classic problem solving experiments that required this, like the candle=

I was surprised we will loose a brain weight as we get older. I had been thinking the reason why if we get older we can't memorize well, is just a reaction time. however, we will loose 25% of brain when we become a 70. at the same time, I've heard if someone who uses fingers to do something even we get old, such as playing pianon, violin, or playing Video game also, they won't loose their ability than someone who doesn't. So, I guess we can try to keep our brain by using fingers.
