You’ve almost certainly seen the dancing gorilla video which demonstrates the theory of change blindness—a phenomenon which means we don’t see changes we’re not expecting. Now, an updated experiment shows that the same may be true of radiologists analyzing CT images. More »
It’s generally not a good thing to be biased. Sure, you can have your opinions, you can even cling to them strongly, but if they start actually altering your perception of reality, things can get messy. Lucky for you, hard-to-read fonts are here to the rescue, and might be able to save you from opinionated ranting. More »
The interesting thing about research into video games is that depending on which side you listen to, video games either turn players into insanely violent criminals or video games can make you a better person. One of the latest bits of research performed using a video game comes from Boston Children’s Hospital.
In the study, researchers used traditional treatments with children ranging from age 9 to 17 that had anger control issues. The traditional treatment involved cognitive-behavioral therapy, relaxation techniques, and social skills. One group of 19 children only received the standard treatments.
A second group of 18 children received the same standard treatments and played a video game called Rage Control for the last 15 minutes of their session. The video game, which sounds rather like Space Invaders, required the children to keep their heart rate under a preset limit or lose the ability to destroy enemy spaceships. The researchers found that the group who played the video game were significantly better at keeping their heart rates down and showed clinically-significant decreases in anger scores on standardized tests.
The study appears in the October 2012 issue of Adolescent Psychiatry.
MIT’s Nexi robot has been teaching us about social interaction for years, and has even done a stint with the US Navy. Its latest role, however, involved studying those moments when society falls apart. Northeastern University researchers made Nexi the key ingredient of an experiment where subjects were asked to play a Prisoner’s Dilemma-style game immediately after a conversation, whether it was with a human or a machine. Nexi showed that humans are better judges of trustworthiness after they see the telltale body language of dishonesty — crossed arms, leaning back and other cues — even when those expressions come from a collection of metal and plastic. The study suggests not just that humans are tuned to watch for subtle hints of sketchy behavior, but that future humanoid robots could foster trust by using the right gestures. We’ll look forward to the friendlier machine assistants that result… and keep in mind the room for deception when the robots invariably plot to take over the world.

Technology pervades our lives. But while many writers argue that such a phenomenon should see us rebel and take time away from our gadgets to experience some notional “real life”, Nathan Jurgenson has other ideas. Instead, as he sees it, there is no offline any more. More »
