A couple of studies on perception. First,there's now wisual data to back up the idea that everything looks kind of gray when you feel blue.
Researchers are examing how the * responds to the different white and black contrast situations. They did the tests on healthy subjects on patients with depression. Turns out that depressed people have much lower * response- even if they are on *. And the worse the depression, the worse the performance of the *. In fact, the * reaction alone was a good diagnostic of depression. So the world really can look blea. to somebody who is depressed.
The research is in the journal Biological Psychatry. Study 2 looked at test subject impressions of the honestry of simple factural statements made by other people. The researchers found that the listeners were less likely to believe speakers with foreign accent. And the heavier the accent, the less believable they were perceived to be.
The work appears the Journal of * Social Psychology. So, our own accent preferences could affect how much when we hear from reports, * , job applicants. Others whose accent differs from our own. **

You'd think an animal that hops, would know how to land. But for a kind of frog, that's not the case.
Imagine trying to catch a frog. You reach and they jump, only to land gracefully on their feet a few feet away. It was thought that all frogs move this way. They'd push off their backlegs and then once in flight R the limbs forward. Then, they landed forelimbs first. But researchers compared frogs of the family L, which still S an ancient physiology, to more modern frog species.
Unlike their more graceful cousins, the primitive frogs kept their blacklegs straight out after they jumped. So they don't land on their feet. Instead, they do an ungainly belly flop and struggle to get to their feet and jump again. The finding is in the journal N.
The scientists say that the backleg push-off must involve first, with the ability to E and land softly evolving later. Although the bad landers are still around, their more controlled relatives appear to be better at making longer trips, * for food and, most importantly, avoiding other animals that have an interest in frog legs for dinner.
Have you ever bought a new electronic device or tried a new activity , and then dropped it because you were sure you couldn't possibly master it? Well, don't give up so quickly.
Researchers performed 6 experiments that involved subjects trying out new tasks, including drawing an image from looking at its reflextion in a mirror and learning to type on a new kind of keyboard. The participants were first asked how long it would take them to learn the task. They tended to be overconfident and thought they'd do better on the first try than they actually did.
Then after trying, they were asked * they become good at it. But this time, they were p and thought it takes them longer to learn than it actually did. The study is in Journal of Consumer Research.
The findings are relevant, because many new consumer goods are quickly T aside. It could be because peopole intially think that their fancy new MP3 player would be easy then after their try, they are sure they never be able to master it. So you will be able to ski or use that Ipad later than you expected but sooner than you think.
