Here is some material provided by Janet Peasant that relates to the link between cognition and emotion.

Modulation of visual processing by attention and emotion windows on causal interactions between human brain regions

And some follow-up material provided by Bob Patterson.

QUEST Discussion Topics and Weekly News

Mar 26th, 2010

1.) Embodied Intelligence – Our first topic will center on a news article that we came across this week, titled Mind over matter? How your body does your thinking’ from NewScientist.  The article talks about the strong link between thoughts and actions, an issue that we have talked about in great detail in the QUEST group.  If you are planning to attend or phone-in to the meeting tomorrow give the article a read (you can follow the link above or see a short summary in the news articles below for this week) and come prepared to discuss.

2.) ‘Can computers help overcome limitations in human decision making?’ – recent article by Maule.  This is an area we have been concentrating on in our QUEST group and have taken the position that to ‘integrate’ humans and machines there needs to be ‘alignable’ representations by both the computer and the human.  To design representations for a computer that a human can align to requires an understanding of human decision making/thinking.  This article reviews some of the literature, we also have a ppt for this material as well.

Unanswered query from last week

The goal: Try to find this study through any means possible.

The study involves an analysis of what sort of nutritional regimen results in the biggest and best pigs.  The researchers split the pigs into three groups, with three different sources of nutrition for each group.  The first group of pigs was fed the standard pig grub (cornmeal, oats, etc).  The second group of pigs was fed the output (read: excrement) from the first group.  Finally, the third group of pigs was fed the output of the second group.  They allowed this setup to run for awhile, and when they collected their results, they got some surprising results.  The second group of pigs had grown to be the largest of the three, and the first and third groups were comparable in size. 

Dr. Kabrisky believes that the study was conducted at a school of agriculture somewhere in the breadbasket part of the country (area bounded by Minnesota, Nebraska, Ohio, and Georgia).  Pushed farther he believes that it may have originated from the Iowa Institute of Science and Agriculture or maybe from the University of Illinois.  He thinks that it has been in his memory for at least 40 years, maybe longer.

Anyone interested in trying to track down the study, please try to keep track of the search path that you followed or any search terms that you used successfully. We look forward to another successful result from our social search experiment!

QUEST Discussion Topics and Weekly News
Mar 12th, 2010
1.) Can a computer feel?  This is the same as saying can a computer ever generate qualia?  The dominant topic for QUEST this week is the discussion on Types of qualia in humans.  We have a ppt on the topic and have generated summary information slides also.  Our goal is to examine from our list of types of qualia the behavioral and phenomenal characteristics for them leading to a set of engineering characteristics for representing them in QUEST solutions.  Such solutions are our only hope for solving the wicked problems we face in fighting adaptable foes (like insurgents, cancer, cyber warriors). 
2.) This is an article from Physics Today that was brought to our attention by Dr. George Vogel.  His comments on the article and why we in the QUEST group might be interested in the material…
As far as my comments on the article, all of the music illusions were the result of our brain (Libet soup) unconsciously interpreting what we are hearing based upon our experience.  I thought it interesting that Helmholtz ( back in the 1890s) was thinking along the same lines as we are.  (See middle of the highlighted box by his picture.)  The last two paragraphs in the article are consistent with our findings in the Friday meetings. 

Anyone interested in reading the full article can follow this link to purchase it. We also have some summary slides for anyone interested.

As far as my comments on the article, all of the music illusions were the result of our brain (Libet soup) unconsciously interpreting what we are hearing based upon our experience.  I thought it interesting that Helmholtz ( back in the 1890s) was thinking along the same lines as we are.  (See middle of the highlighted box by his picture.)  The last two

Anyone interested in reading the full article can follow this link to purchase it. I will also post some summary slides that we put together.

Growl distinction

http://www.newscientist.com/video?bcpid=25196461001&bclid=1904732932&bctid=70820588001

The link above takes you to a video from New Scientist examining a dog’s interpretation of recorded growls as it approaches a food source.  Interesting to see the different reactions.

Comment from Capt Amerika: really interesting example of ‘alignment’ – even
without the multiple sensor inputs of the threatening visual input the
auditory signal has resolution of several types of qualia – tentative
growl, scared growl, and finally dominant protection growl associated
with protection of food

Other topics for this week’s QUEST meeting

2.)  Janet Peasant forwarded us the link to a very interesting site on the topic of neuroethics.  We have assembled a brief powerpoint presentation of the material for anyone interested, or you can feel free to go to the site yourself and explore the material.

http://neuroethics.upenn.edu/index.php/penn-neuroethics-briefing/overview-of-neuroethics

3.)  We recently came across an interesting article from this month’s issue of the IEEE med and biology magazine.  The title is ‘Consciousness Platform; The Greatest Mystery of All Time’, written by Sid Deutsch.  We cannot post the original article, but we do encourage interested parties to look it up and give it a read.  We will probably start a discussion on the material in this week’s QUEST meeting, so anyone who cannot access the original article please let me know and we will ship you our notes on it.(Associated ppt for anyone interested)

4.)    Types of qualia discussion (Associated ppt for anyone interested)

5.)    Storage of qualia – gists and links. (Associated ppt for anyone interested)

6.)    Another area of interest to us, we have talked in the past about the usefulness of being able to group/cluster social media outlets based on more than just keyword comparison.  This group is doing some really interesting work in that field regarding blog organization and modeling interactions.

A general site listing the group’s project description can be found here.  Also you can follow the links below to download some of the selected pdfs that we have been reviewing.
