QUEST Weekly Meeting, September 11th

Topics for QUEST 11 Sept, 2009:
1.)  The major discussion will concern a recent document sent by Dr. Tsou on Color and qualia.  Brian will try to explain to us the material.
2.)  I would like to discuss points associated with my proposed next think piece: ‘What Turing meant to Say – and the implication to trusted computing’.
3.)  There was also an issue of Scientific American on the Mind that had a series of articles of interest – below are some of the points that we might discuss:

QUEST blog informational comments on Scientific American Mind issue 2009:
1.)  Article on botox impact on feelings:  botox recipients and others suggests that our emotions are reinforced—perhaps even driven—by their corresponding facial expressions… we’ve seen this idea before that low level body actions (possibly impacting emotions)… feel emotions isn’t just restricted to our brain—there are parts of our bodies that help and reinforce the feelings we’re having,” … they are wrong here – As we said earlier – those parts of our body are not autonomous – they are driven by our nervous system – just because we don’t have ‘awareness’ of the process doesn’t mean that it isn’t in the brain – it is in what we have called the Libet system .
2.)  Article on memory maintenance critical brain functions change as we age – hippocampus plays a less critical role – activity in the hippocampus steadily declined as subjects remembered events that were up to 12 years old
3.)  Poof forgotten memories – interesting article on the ‘non-saccade’ exposure of visual data doesn’t slowly degrade but immediately disappears … such memories actually stay sharp until they are suddenly lost
4.)  Smiling predicts successful marriage potential – pictures of young children can predict whether they will later in life have a successful marriage – also done for college kids … weakest smilers in college photographs, one in four ended up divorcing, compared with one in 20 of the widest smilers
5.)  Speed dating data on women more choosy flips when the women are the rotating person and the men sit and get visited.
6.)  Interesting article on different theories of solving the correspondence problem – aligning the two disparate images from our eyes – Helmholtz, Julesz and Ramachandran… found that in some circumstances form perception preceded stereo, showing the flexibility of the brain’s visual centers…in this case, form perception occurred prior to stereo…
7.)  Do fish experience pain? – New research, however, suggests that they may…“fearful, avoidance behavior.”
8.)  Article on when does consciousness arise:  suggest fetus is in state of sleep …, article by christof Koch… I wager that the fetus experiences nothing in utero; that it feels the way we do when we are in a deep, dreamless sleep
9.)  Hearing in a complicated environment – tapering response, a much simpler mechanism than the earlier theory
10.) Series of articles on pain
1.)  Myths about UAVs – four myths are covered: The Air Force still trains more pilots for manned airplanes than it trains UAV controllers.; For every UAV in the air on a mission, there are three others in inventory; UAVs aren’t unmanned—they’re remotely controlled.; Reapers and Predators are more useful for snooping on enemies than killing them.
2.)  Using the Netflix approach to ‘blacklist’; new blacklisting method is mainly theoretical… predictive blacklisting method proposed by University of California-Irvine researchers employs a combination of factors to improve blacklisting, such as trends in the times of attacks, geographical locations and IP address blocks, and any “connections” between the attacker and the victim, such as if an attacker had hit a victim’s network before.
3.)  Article from ny times on patient handoffs – exactly a problem we had discussed this summer at TecEdge
