Robots Learn to Lie and Deceive Each Other in Search for 'Food'

If you grew up with a few brothers and sisters, you know there are certain unspoken rules when it comes to food. You have to move fast without being noticed to get the last fish stick. According to a new study, it's not just humans who can learn these survival rules; robots can, too.

Technology Review reports that a team of scientists at Switzerland's Ecole Polytechnique Fédérale de Lausanne are soon to release a study on robots equipped with artificial neural networks and programmed to locate 'food.' When a robot neared the 'food,' it flashed a blue light so other robots could also find it. With limited space around the 'food,' the robots soon learned this wasn't the best idea. The researchers copied and combined the artificial neural networks of the most 'intelligent' robots, and made a few changes to the code to mimic biological mutations. As a result, the robots 'evolved' -- learning not to alert other each other to the food. After a few hundred (increasingly intelligent) 'generations,' the majority of robots didn't flash a light at all.

Embarrassing Online Photos: Not Going Away Anytime Soon

More Online Embarassment To Come Before Lessons are LearnedRemember the tale of Kevin Colvin? He was an intern who called in sick, only to be caught lying to his boss thanks to pictures of himself attending a party posted on his Facebook page. Colvin was famously called out by his boss, and then fired, leaving many shaking their heads and wondering how someone could do something so stupid. The answer, according to columnist Helen A. S. Popkin at least, is evolution -- or the lack thereof.

Popkin makes the case that we're simply not used to the ramifications of our online behaviors because it's all too new. We know instinctively, for example, to not go taunting grizzly bears or jumping from tall places, but sharing pictures of ourselves online is something new, exciting, and, as we're increasingly learning, equally dangerous. Unfortunately it's going to take a long time before you get that same queasy feeling in your stomach before posting that you might get before taking a leap from a high diving board, so until then keep reading and keep laughing -- you're learning something.

Surfing the Internet Alters Development of the Brain


New research from the University of California, Los Angeles (UCLA) shows that the Internet and technology is already changing the development of the human mind. Gary Small, the director of the Memory & Aging Research Center at the Semel Institute for Neuroscience & Human Behavior and the Center on Aging at UCLA (phew...), has found that activities such as text messaging and Internet searching improves a person's ability to filter information, perform complex reasoning, and make quick decisions.

Small warns, however, that these evolutionary advancements are coming at the expense of face-to-face social skills and he warns of the danger of Internet addiction. "The brain is very specialized in its circuitry, and if you repeat mental tasks over and over, it will strengthen certain neural circuits and ignore others," he says. He also told Reuters in an interview that those who are able to combine both the new technologically developed skills and traditional social abilities will be the most successful in years to come.
