A study conducted by the University of Toronto has found that exposure to fast-food logos can cause people to feel impatient and make them more likely to buy things. Subjects in the study were exposed to nearly imperceptible flashes of images (for 12 to 80 milliseconds) which included fast-food logos for some. The subjects were then asked to read about and choose between two different kinds of skin-care treatments, one of which was a three-in-one. Those who had the logos flashed before them read "significantly faster" and chose the more time-saving skin product. From the article: "The researchers concluded 'fast food, originally designed to save time, can have the unexpected consequence of inducing haste and impatience' and 'preference for time-saving products when there are potentially other important aspects upon which to choose a product.' So, basically, driving past a McDonald's on the highway has the potential to not only make you drive faster, it will make you more likely to buy two-for-one Pantene Pro-V Shampoo and Conditioner the next time you go to Duane Reade. One, it seems, is considerably less ominous than the other." I guess this explains why my nephews will chew on their seat belts and try to get out the windows just to be first into the McDonald's Playland.

The Digital Foundry blog took an in-depth look at how Sony is introducing 3D technology to PlayStation 3 games. They give a step-by-step description of how the system generates a 3D frame (or rather, a pair of frames), and the graphical hurdles that need be to overcome to ensure the games look good. The article also discusses some of the subtle effects 3D technology can have on gameplay: "'One interesting thing came through in the immersion aspect was that in the first-person camera view, it felt so much more like being there. Typically when most people play MotorStorm, something like 90 per cent play in the third-person view,' Benson explains. 'As soon as we put the 3D settings in place, the first-person view became a lot more popular, a lot more people were using that view. This could indicate that 3D could perhaps change the standards, if you like.' ... 'We found that in the first-person view the game is giving you all the sorts of cues that you're used to in normal driving: speed perception, the ability to judge distances, things like that. It's far easier to avoid track objects.' The insertion of true stereoscopic 3D into MotorStorm also brings about a new sense of appreciation of the scale and size of the game world and the objects within it."

If you ask fans of first-person shooters what feature they'd like to see in a new game, their answers — now and for the past 15 years — probably involve destructible environments. Game developers have tried to satisfy this demand with scripted events, breakable objects, and more crates than you can shake a rocket launcher at. However, Bodycount, an upcoming game from Codemasters Guildford, is aiming to deliver what gamers have wanted for so long: the ability to blast apart whatever you please. Quoting the Guardian's games blog from their hands-on with the game: "... it's not just about effect, it's about access. In Bodycount, you can blow chunks out of thinner interior walls, allowing you to burst through and catch enemies by surprise. You can also brilliantly modify cover objects – if you're hiding behind a crate and want to take out enemies without popping up from behind it, shoot a hole in it. Bingo, you've got a comparatively safe firing vantage. The difference between this and say, Red Faction or Bad Company, is that the destruction isn't limited to pre-set building sections. It's everywhere. This should, of course, grind the processor to a halt, but the team has come up with a simple compromise to facilitate its vision. 'The trick is that we're not running full physics on everything,' explains lead coder, Jon Creighton. ... This is tied in with one of the best cover systems I've ever seen. While in a crouching position (gained by holding the left trigger down), you can use the left analogue stick to subtly look and aim around your cover object, ducking and peeking to gain that perfect view of the war zone. It's natural, it's comfortable and it's adaptive, and it will surely consign the whole 'locking on' mechanic to the graveyard of cover system history."
