Ophthalmologists Told About The New Features Of The Human Eye.
Simply imagining scenes such as a cloudless date or a night sky can cause your pupils to mutation size, a new study finds. Pupils automatically dilate (get bigger) or catch (get smaller) in response to the amount of light entering the eye. This study shows that visualizing overcast or bright scenes affects people's pupils as if they were actually seeing the images.

In one experiment, participants looked at a partition with triangles of different levels of brightness. When later asked to for granted those triangles, the participants' pupils varied in size according to each triangle's brightness. When they imagined brighter triangles, their pupils were smaller, and when they imagined darker triangles, their pupils were larger.

A New Technique For Reducing Cravings For Junk Food

A New Technique For Reducing Cravings For Junk Food.
Researchers crack that they may have hit on a unheard of trick for weight loss: To eat less of a certain food, they suggest you imagine yourself gobbling it up beforehand. Repeatedly imagining the consumption of a food reduces one's proclivity for it at that moment, said lead researcher Carey Morewedge, an assistant professor of social and arbitration sciences at Carnegie Mellon University in Pittsburgh. "Most people think that imagining a viands increases their desire for it and whets their appetite. Our findings show that it is not so simple," she said.

Thinking of a food - how it tastes, smells or looks - does extend our appetite. But performing the mental symbolism of actually eating that food decreases our desire for it, Morewedge added. For the study, published in the Dec 10, 2010 promulgation of Science, Morewedge's team conducted five experiments. In one, 51 individuals were asked to ponder doing 33 repetitive actions, one at a time.

A restrain group imagined putting 33 coins into a washing machine. Another band imagined putting 30 quarters into the washer and eating three M&Ms. A third aggregation imagined feeding three quarters into the washer and eating 30 M&Ms. The individuals were then invited to break bread freely from a bowl of M&Ms.

Those who had imagined eating 30 candies in fact ate fewer candies than the others, the researchers found. To be steadfast the results were related to imagination, the researchers then mixed up the experiment by changing the number of coins and M&Ms. Again, those who imagined eating the most candies ate the fewest.
