Hotel Grand International – Seoul, South Korea

Here are some notes that I took on my tablet using MS ONENOTE.  That might explain that terrible appearance because these are all based on MS handwriting recognition.

International Symposium on Learning 2006 sponsored by KAST

1st speaker = Daeyeol Lee

Neural mechanism of reinforcement learning and decision making

* Monkey video

-sound of brain activity with different movements/decisions

* Matching pennies-studied via game theory (ie, Nash in beautiful mind)

-No behavior is random

-Animal must randomize choices, otherwise computer will play off of strategy. This is the reinforcement model

* Dors-lateral prefrontal cortex-association with learning behaviors

IX Essentially, it seems that fewer neurons fire after repeated trials

* Sondheim-seems a little like and” no duh” town Supp J conclusion

This could indicate that once connections are made, future decisions

require less of a load on the brain.

Conclusion – Seems like a “no duh” conclusion.

Overall, a great speaker. He really made the topic interesting and engaged the audience. Interesting research.

Amy Poremba -Learning and Memory in the Auditory System

Testing auditory signals and learning behaviors In rabbits.

* what is the brain doing during learning

-removed brain segments to isolate areas necessary for learning

if tone is accompanied by shock received in animal’s foot.

* Sensory modalities are used at the same time (auditory/verbal)

* environmental attributes can effect learning. I wish that this would

have been clarified better throughout the presentation.

panel discussion

Operant Conditioning (evident in previous speakers work)

-law of effect – the response is a function of its consequences.

-theory of mind. ability to build models and guess whet others are dtp thinking.

this into is the used to predict actions and counter-measures

can be taken.

-Moves from Operant Conditioning to more of a Cognitivist theory of a processing model.

-Operant Conditioning cannot explain the thought process in game theory

Would it make a difference if the experiments were done with 2 monkeys as opposed to I monkey Vs./ computer?

-Yes, but this will take awhile to do.

Can your research explain decision making? (improve. decisions-making)

Is there a universal learning process?

There are many Similarities in animal models.

She essentially stated the operant conditioning has a major place in learning.
