Magic in Mind

How magicians control your mind. "Magic isn't just a bag of tricks - it's a finely-tuned technology for shaping what we see. Now researchers are extracting its lessons (PDF)." [Via BB and MH]

Wei Wu Wei

fcummins — Tue, 01 Jul 2008 12:58:42 -0800

Terence Gray was an English born aristocrat of an Irish family. He tried his hand at Egyptology, drama and theater, but gave it up to keep the family vineyards in the Monaco. He owned the winner of the 1957 Ascot Gold cup. He also became a mystic. Writing as Wei Wu Wei, he produced 8 little books between 1958 and 1974. They are articulate, witty, and above all informed by a vast knowledge of Zen, Taoist and Hindu intellectual tradition. Beholden to none, he makes increasing sense in a modern context. Many of his insights are very close to some current views within cognitive science and the philosophy of mind. But cognitive science has flirted with Buddhism before.

"Attention regulation and monitoring in meditation" (PDF). A recent article in Trends in Cognitive Sciences on the neuroscience of meditation, focusing on how meditation alters and sharpens the brain's attention systems. The research is being done at the Waisman Laboratory for Brain Imaging and Behavior (previously), who have also recently published research on the "Regulation of the neural circuitry of emotion by compassion meditation" (PDF), which describes how meditation can cultivate compassion by physically affecting brain regions that play a role in empathy. They shared this research with the Dalai Lama at the recent Seeds of Compassion forum.

Chick Sexing

"Over and over he scoops up a chick with his left hand, expels its droppings with a squeeze of his thumb, opens its vent with his fingers, peers through the magnifying lenses attached to his spectacles and determines its sex." It's a dirty job (YT). Sexing chicks early is important so that the cockerels can be separated and culled^ or fed to be broilers^. The obvious differences take weeks to develop, so when the vent sexing method was developed in Japan in the 1920s, professional chicken sexers became sought after. After years of training, they can sex a thousand day-old chicks an hour with 99% accuracy. In many cases the sexer cannot say why he made a particular decision. The method is learned mostly empirically and is not open to introspection, which has made it of considerable interest to philosophers and cognitive scientists. Vent sexing is in decline, however, owing to development of feather sexing (i.e. using breeds with differences in feather length or color). Would you like to learn to sex chicks? There are plenty of resources, such as A Guide to Sexing Chicks (1935). Better yet, The Specialist Chick Sexer is a modern treatment (there is an extract and another poultry essay available). You can sex all fowl, actually. Cognitive scientists, philosophers, and psychologists all like chicken sexing. Biederman (of geon^ fame) and Shiffrar showed (PDF) that novices can be trained to decent accuracy with explicit perceptual clues. There's a discussion of chicken sexing in the defunct PSYCHE-B cognitive science listserv (more useful archive here). Scroll down to see it, particularly Bruce Mangan's post. (There was an earlier post, and the main link is good if you can get access.)

Nicod Lectures

painquale — Mon, 29 Oct 2007 02:05:51 -0800

Since 1993, the Institut Jean Nicod has awarded the annual Jean Nicod Prize to a leading philosopher or cognitive scientist for his or her work in the interdisciplinary study of the mind. The recipient is expected to deliver a series of lectures. The lecture series of this past year's winner, philosopher Stephen Stich, is entitled "Moral Theory Meets Cognitive Science: How Cognitive Science Can Transform Traditional Debates", and is now available online in video form. Also available is the lecture series of the previous year's winner, evolutionary anthropologist Michael Tomasello: "Origins of Human Communication". The first Tomasello video is not of high quality, but the rest are fine. Other talks associated with the Institut Jean Nicod are here and here. The site hosting the Nicod lectures has a number of other interesting videos; the directory of lectures in English is here. (Lots of lectures on semiotics, it seems.)

Jeff Hawkins unleashes his brain: Numenta's new AI platform

grumblebee — Wed, 04 Apr 2007 13:35:42 -0800

Jeff Hawkins, co-founder of Palm and Handspring, has started a new company, called Numenta, to test his controversial theory of intelligence. Whether you find his theory plausible or not, his book, "On Intelligence" is fascinating. Numenta is attempting to build A.I.s using Hawkins' theory as a backbone. They've developed a software engine and a Python-based API, which they've made public (as free downloads), so that hackers can start playing. They've also released manuals, a whitepaper (pdf) and videos [1] [2]. (At about 30:18 into the first video, Hawkins demonstrates, with screenshots, the first app which uses his system.)
