Net stimulates the brain: Study

A study presented this month at the Society for Neuroscience found that Internet training "could potentially enhance brain function and cognition in older adults," ScienceDaily.com reports. Researchers at University California, Los Angeles, worked with two groups of "neurologically normal volunteers between the ages of 55 and 78." Everything else being pretty equal, one group was made up of regular Internet users, the other had very little online experience. The latter group "performed Web searches while undergoing functional magnetic resonance imaging (fMRI) scans, which recorded the subtle brain-circuitry changes experienced during this activity." After training and just seven days of an hour a day of Web research over a period of two weeks, the newly Net-savvy group "were able to trigger key centers in the brain that control decision-making and complex reasoning," displaying "brain activation patterns very similar to those seen in the group of savvy Internet users." Here's a host of coverage.

Bing: Microsoft's new search engine

It's not just a search engine, it's "a decision engine," Microsoft says. So it's not trying to replace Google, just offer a different kind of service, one requiring fewer clicks, in some cases. "For example, if you type in the name of a city you get local weather, hotel prices and other information without having to click anywhere," reports ConnectSafely.org co-director Larry Magid in the San Jose Mercury News. "Bing is not only visually more attractive, it's also more informative," he adds. In "Bing it on," USATODAY reports that "you can also search for images and video, with a 'smart video preview' that lets you peek at 30-second clips (hula dancing, Don Ho) by scrolling over the video. You can play the video from the Bing results page, no matter where on the Web it is coming from."

To try it, just go to Bing.com. For filtered search, click on "Extras" in the extreme upper-right-hand corner, then on "Preferences." "SafeSearch" is at the top of that page. "Moderate" filtering seems to be the default. After you've chosen "Strict," "Moderate," or "Off," be sure to click on "Safe Settings" over on the right (and if this is on your child's computer, you'll probably need an accompanying rule that no one changes the setting without permission). You may want to extend the setting and rule to all search engines and household computers, but if kids (or their friends) aren't compliant, you may need a backup plan (which sometimes means turning on filtering at the operating-system level or installing filtering software).

THIS JUST IN!: After I wrote the above about SafeSearch, Larry Magid, my ConnectSafely co-director tested it with Bing's video search, and parents probably won't be pleased by what he found: In video search, but with SafeSearch filtering set to "Strict," he typed a word sure to turn up porn in the search box. "I was first warned that it 'may return explicit adult content' and told that 'to view these videos, turn off SafeSearch.' One click later, SafeSearch was off, and I was looking a page of naughty thumbnails. And, as advertised, hovering the mouse over a thumbnail started the video and audio. Even when playing in a small thumbnail, it was unmistakably hard core porn," Larry writes in CNET.

Finding bog snorkelers in MySpace

Well, this isn't just about finding bog snorkelers (for the great unwashed, I'll get to what it is in a moment). It's about how easily journalists and other users of search engines (maybe parents too) can find people in any social-networking site. The article in Journalism.co.uk shows how easily reporters can search social sites for case studies and background info and how easily that can turn up the most specific details about people's lives. Within 10 minutes the writer -who'd set out to "find private information" about someone under 16, including where s/he could be found - "was able to find the mobile number of a 15-year-old girl in South London, the address where a 17-year-old waitress is employed in Kent," etc. The article shows how to do advance searches, for example for "pro-ana" sites (supporting anorexia) or bog snorkelers, preferably in a general search engine such as Google, not in the social site itself: "If you are doing research on the fury caused by pro-anorexia sites on the web then you will find only a handful of 'pro-ana' ... references using Bebo's search tool. But more than 170 Bebo pages can be found in Google using this search string: site:.bebo.com inurl:profile inurl:bebo 'pro-ana'." For "bog snorkeling," 120 results in MySpace were turned up with this string: site:myspace.com inurl:myspace inurl:fuseaction "bog snorkelling". As for what bog snorkeling is, it's a competitive sport - sometimes combined with running and mountain biking in a new kind of triathlon - see this page in Wikipedia for more.

We're all becoming Net-trained info-gatherers

Apparently we're all becoming the rapid-fire, uncritical information hunter-gatherers we had thought only our children were. Yes, they're the digital natives but, according to a new study out of the UK, the Internet is "training" all of us to approach information this way, which may mean we all have to work extra hard now to think more critically and analytically. A just-released longitudinal study from University College London found that, "although young people demonstrate an apparent ease and familiarity with computers, they rely heavily on search engines, view rather than read and do not possess the critical and analytical skills to assess the information that they find on the Web," its press release. Titled "Information Behaviour of the Researcher of the Future," the study also found that the research behaviors "commonly associated with younger users – impatience in search and navigation and zero tolerance for any delay in satisfying their information needs – are now becoming the norm for all age groups." A longitudinal study tracks its subject over a period of time, and this was a "virtual longitudinal study" - see p. 6 of its pdf version for an explanation. This one was commissioned by the British Library and the Joint Information Systems Committee to get a handle on "the changing needs of researchers and other users." Thanks to tech educator Anne Bubnic in for pointing this study out.

Half of us search for ourselves...

…or someone else in Web search engines, according to the latest study by the Pew Internet & American Life Project. The exact figures are 47% searching for ourselves, up from 22% in 2002, and 53% searching for others. The findings "reflect how people are sharing more and more of their lives on the Internet, as well as how Web 2.0 sites such as YouTube, Flickr, Facebook and MySpace are encouraging users to post their home videos, photographs and personal profiles online, including data ranging from their favorite movies to their cell phone number," the San Francisco Chronicle reports. In other findings, some 36% of us have searched for someone we've lost touch with and 9% have "dug up information on someone they were dating." In its coverage, the Associated Press reports that teens are "more likely than adults to restrict who can see their profiles … contrary to conventional wisdom." In other findings, some 36% of us have searched for someone we've lost touch with and 9% have "dug up information on someone they were dating," according to the Chronicle. Note that 60% of us are not worried about how much information about us is online, sixty-one percent "have not felt compelled to limit it," and 38% use privacy controls. The Pew/Internet study - "Digital Footprints: Online identity management and search in the age of transparency" - is here.
