Twenty years ago, Wozniak realized that computers could easily calculate the moment of forgetting if he could discover the right algorithm. SuperMemo is the result of his research. It predicts the future state of a person’s memory and schedules information reviews at the optimal time. The effect is striking. Users can seal huge quantities of vocabulary into their brains. But for Wozniak, 46, helping people learn a foreign language fast is just the tiniest part of his goal. As we plan the days, weeks, even years of our lives, he would have us rely not merely on our traditional sources of self-knowledge — introspection, intuition, and conscious thought — but also on something new: predictions about ourselves encoded in machines.
Given the chance to observe our behaviors, computers can run simulations, modeling different versions of our path through the world. By tuning these models for top performance, computers will give us rules to live by. They will be able to tell us when to wake, sleep, learn, and exercise; they will cue us to remember what we’ve read, help us track whom we’ve met, and remind us of our goals. Computers, in Wozniak’s scheme, will increase our intellectual capacity and enhance our rational self-control.
A tiny chemical “brain” has been invented by Scientists at the National Institute for Materials Science in Tsukuba, Japan. With a size of two nanometers, the molecular device is capable of controlling eight of the microscopic nanobot machines simultaneously.
The size of the U.S. market for brain stimulation products — which can range from games such as Nintendo Co Ltd’s Brain Age to programs backed by research showing they can improve memory or other cognitive functions — more than doubled between 2005 and 2007 to $225 million, according to a new report by the consulting group SharpBrains.
Daniel Terdiman of CNET writes about the new Emotiv “headset that seems a little like the one from the James Cameron-written 1995 film, Strange Days, complete with a set of sensors that are built to read your brain waves.
The software then is designed to interpret those brain waves in such a way as to allow users to manipulate objects onscreen with nothing but their mind.
Migatti, PARC’s artificial intelligence software for mobile devices, could soon be data-mining your life:
(R)esearchers at Palo Alto Research Center (PARC)… have developed software that turns a phone into a thoughtful personal assistant, one that helps people find fun things to do. The software, called Magitti, uses a combination of cues–including the time of day, a person’s location, her past behaviors, and even her text messages–to infer her interests. It then shows a helpful list of suggestions, including concerts, movies, bookstores, and restaurants [via Technology Review]
This summer, neuroscientist Ian Robertson polled 3,000 people and found that the younger ones were less able than their elders to recall standard personal info. When Robertson asked his subjects to tell them a relative’s birth date, 87 percent of respondents over age 50 could recite it, while less than 40 percent of those under 30 could do so. And when he asked them their own phone number, fully one-third of the youngsters drew a blank. They had to whip out their handsets to look it up. [via Wired]
A mind is a terrible thing. Whether because of the brain’s internal structure or the way social and cultural pressures cause our minds to develop and function, in the end the result is the same: minds that are not only easily deceived and frequently deceptive in their own right, but when caught out, refuse to accept and address their errors. If you have a mind — or even half a mind — you might be best off losing it entirely. Barring that, though, there are a few things you should know about the enemy in your head. Before it hurts someone.
Some recent developments in the area of human-computer interface promise control of software [including game avatars, soundtracks, and more] via thoughts and emotional responses rather than keyboards or joysticks.
Emotiv Systems, an electronic-game company from San Francisco, wants people to play with the power of the mind. Starting tomorrow, video-game makers will be able to buy Emotiv’s electro-encephalograph (EEG) caps and software developer’s tool kits so that they can build games that use the electrical signals from a player’s brain to control the on-screen action… S.M.A.R.T. BrainGames, a company based in San Marcos, CA, sells games and EEG caps designed to treat people with attention deficit/hyperactivity disorder. [via Technology Review]
10. Sit up straight, and close your mouth: Good posture affects our state of mind, and helps us to think more clearly. Wanna prove it to yourself? Try solving some math in your head while slouching, looking at the floor and letting your mouth hang open. Then do the mental math while sitting up straight, keeping your mouth closed and looking forward or slightly upwards. You’ll get the point.
14. Make connections: To grow longer dendrites, do something new. Try learning a new language or developing a skill such as drawing, and you’ll see instant changes in how you think.
20. Graze: To give your brain a steady supply of energy and minerals, eat little and often. Eating large meals shunts blood to your digestive tract, away from your brain.
25. Make friends: Preferably ones with large amounts of frizzy grey hair. Recent research showed that hanging out with boffins can boost your IQ by up to 10 percent.
“The Department of Defense’s “Augmented Cognition” video is supposed to represent a plausible scenario for a human-computer interface that uses EEG and other technologies to figure out what to feed to operators, allowing teams to do fast analysis of giant amounts of data.” [via boingboing]
