Last week, Nintendo became the latest consumer electronics maker to warn that kids shouldn’t use their three-dimensional image-based gaming devices because they may have a negative impact on development of the human visual system.
The warning came just a month before the company’s much anticipated release of the 3DS, which is just such a device that features a 3.5-inch screen which can create 3-D images without the need for special glasses. The 3DS is Nintendo’s most anticipated new product since it released the iconic Wii gaming device in 2006.
Sony’s PlayStation3, a similar product that requires glasses to create the 3-D effect, already carries a similar warning, as do 3-D TV sets made by Sony, Samsung, and Panasonic.
Nintendo’s warning applies to kids that are six years old or younger. The Japanese company advised parents to block access to the game machine’s 3-D mode for these kids, while adding that it was okay for them to use the 3DS in 2-D mode. Read more »

Flashbacks are vivid, recurring, intrusive, and unwanted mental images of a past traumatic experience. They are a sine qua non of post-traumatic stress disorder (PTSD). Although drugs and cognitive behavioral interventions are available to treat PTSD, clinicians would prefer to utilize some sort of early intervention to prevent flashbacks from developing in the first place.
Well, researchers at Oxford University appear to have found one. Remarkably, all it takes is playing Tetris. Yes, Tetris!
The team responsible for the discovery was led by Emily Holmes. The writeup appears in the November issue of PLoS ONE. Holmes and colleagues had reasoned that the human brain has a limited capacity to process memories, and that memory consolidation following a traumatic experience is typically complete within six hours after the event. Holmes’ team also knew that playing Tetris involved the same kind of mental processing as that involved with flashback formation. So they figured if they had people play Tetris during that six-hour window after the traumatic event, it might interfere with memory consolidation of the traumatic experience. That, in turn, would reduce or eliminate the flashbacks. The idea worked like a charm. Read more »
