The Deep Mind of Demis Hassabis - "The big thing is what we call transfer learning. You've mastered one domain of things, how do you abstract that into something that's almost like a library of knowledge that you can now usefully apply in a new domain? That's the key to general knowledge. At the moment, we are good at processing perceptual information and then picking an action based on that. But when it goes to the next level, the concept level, nobody has been able to do that." (previously: 1,2) [more inside]
Smells can be very hard to identify and name, unless you are given some prompting - or you speak Jahai, the language of an indigenous group in the Malay peninsula.
False memories of fabricated political events [ABSTRACT]. In the largest false memory study to date, 5,269 participants were asked about their memories for three true and one of five fabricated political events. Each fabricated event was accompanied by a photographic image purportedly depicting that event. Approximately half the participants falsely remembered that the false event happened, with 27% remembering that they saw the events happen on the news. Political orientation appeared to influence the formation of false memories, with conservatives more likely to falsely remember seeing Barack Obama shaking hands with the president of Iran, and liberals more likely to remember George W. Bush vacationing with a baseball celebrity during the Hurricane Katrina disaster. A follow-up study supported the explanation that events are more easily implanted in memory when they are congruent with a person's preexisting attitudes and evaluations, in part because attitude-congruent false events promote feelings of recognition and familiarity, which in turn interfere with source attributions.

"Piloting London’s distinctive black cabs (taxis to everyone else) is no easy feat. To earn the privilege, drivers have to pass an intense intellectual ordeal, known charmingly as The Knowledge. Ever since 1865, they’ve had to memorise the location of every street within six miles of Charing Cross – all 25,000 of the capital’s arteries, veins and capillaries. They also need to know the locations of 20,000 landmarks – museums, police stations, theatres, clubs, and more – and 320 routes that connect everything up." Acquiring The Knowledge changes the brains of those who acquire it.
Mapping Memory. "Turn the human brain upside down and all around to see how memories are saved (or lost)." National Geographic has a great interactive 3D map of the brain as part of an excellent feature on memory. [more inside]
Ginkgo supplements don’t help...Um...................um...... A new study suggests ginkgo supplements do nothing to quickly improve memory in healthy people, a finding that goes against years of well-publicized claims that helped turn the supplements into a multimillion-dollar industry.
