For this homework I would like you to go to the urls below and participate in the cow eye dissection.

You can watch the dissection or you can do your own for more class credit if you like. If you film your own dissection and post it you will get more class credit.

Watch: http://www.exploratorium.edu/learning_studio/cow_eye/step01.html

You can do your own using any eyeball you want - fish, cow, etc...

Do: http://www.exploratorium.edu/learning_studio/cow_eye/doit.html

I would the like you to post a narrative type comment in the following format: 1) briefly discuss how your text book presents the relevant information about the eye (use facts and paraphrase the material), 2) do the web activity, 3) post in a narrative format your experience with the activity, and 4) Discuss how well the web site kept its facts and figures correct in relation to the material in your text book.

(Basically I want you to spend equal time in your text book and in the web. I would like you to use the terminology they are using in the book to teach you about the eye in your post. The sort of fact check the site to make sure it is consistent with your text - I am sure they are, but you will need to discuss this. This will take some time, so be prepared to spend it on this homework).

You can turn this in before Friday - if you are going to use a real eye I'll give you more time.

Let me know if you have any questions,

--Dr. M

Most people (even many who work on the brain) assume that what you see is pretty much what your eye sees and reports to your brain. In fact, your brain adds very substantially to the report it gets from your eye, so that a lot of what you see is actually "made up" by the brain.

Biomotion Lab

We are working on several aspects of visual perception and cognition. Our major interest is focussed on questions concerning the biology and psychology of social recognition. That is:

• . detection of animate agents
• . conspecific recognition
• . gender recognition
• . individual recognition
• . recognition of an agent's actions
• . recognition of emotions, personality traits and intentionality
• . face recognition

Interactive Demonstration -

http://www.biomotionlab.ca/Demos/BMLwalker.html

A collection of tutorials and demonstrations related to perception by Dr. Krantz on areas such as visual information in art, size constancy, Foutier analysis, receptive fields, aftereffects, Gestalt laws of perceptual organization, motion and depth.

Go to the site and then look at the two long lines.

Which one is longer? Try moving the two lines on top of each other. Try swapping the end pieces around.

Have a look at this site and gain a better appreciation of eyes. Consider doing your own dissection. Contact your local butcher and see if they have any extras laying around.

A collection of interactive demonstrations. Go through and enjoy the site. Which exhibits did you like the best? Which exhibits relate most to what we have been currently studying in the course?

The Dutch physiologist, Franciscus Cornelis Donders, was the first person to conceive of a way to measure "thinking time", and did so in studies performed in the middle part of the 1860's.

We'll start with a simple brain (or a simple computer) which consists of four simple elements connected as shown to the left. The bottom two ovals we'll call "input" units and the filled circle we'll call an "output" unit. They are actually all we really need (for present purposes), but things will work a little better if we have a fourth "bias" element, the circle with the B in it.

Interactive Demonstration:

The interactive display below can be used to acquire the ability to see Hofstadter's Road Sign in at least four different ways. Controls to the left allow one to bias one's perception by adding apparent barriers and arrows. Controls to the right allow one to vary the color of the dots at various locations in ways that may help one see different patterns.
