Crossing eyes

I've been practising that for the past few days LOL

Hi, Mushroom

Cool! So, what do you see when you move one eye and leave the other still? A blur of what both eyes are seeing, or mainly an image from whichever eye is dominant? If the second, is your dominant eye on the same side as your dominant hand? This is interesting.

Can ya beat this?

Why? why do you wish to master something like that, it's disgusting

0_equals_true: I've read that about 2/3rd of people are right-eyed, about 1/3rd left-eyed and a small minority ambiocular. But that's interesting... do they regain their dominance after their meditating is done?

Other researchers found evidence that meditation can increase attention skills and the ability to stabilize the mind. “Our results support the claim that training in meditation can have a real and measurable effect on an individual’s conscious state,” says Olivia Carter, PhD, of Harvard University. “Although the current study provides no direct evidence that meditation will help alleviate the symptoms of depression or stress, the findings are consistent with reports that experienced meditators are able to control and direct the focus of their attention towards a positive and calm state, in a manner that may help reduce symptoms of stress and depression.”

In the study, Carter and her colleagues examined 76 Tibetan Buddhist monks who had attained meditative training ranging from 5 to 54 years. She examined the ability of meditation to alter their conscious perception using a measure called perceptual rivalry—a visual illusion that is one of the most commonly used tools in scientific studies of consciousness. Perceptual rivalry refers to oscillations in visual perception that can occur during sustained viewing of ambiguous visual stimuli. One famous example involves an image that can be perceived as either two faces or a vase. When this image is viewed the observer’s conscious experience will generally switch between the two “competing” interpretations of the image. Only one of the two images will be consciously perceived at any given moment, while the non-dominant image will be totally suppressed from consciousness. After a few seconds, the relative dominance of the two images will then switch. The neural events underlying perceptual rivalry are not well understood, but are thought to involve mechanisms within the brain that regulate attention and conscious awareness.

The monks perceptual experience of visual rivalry was tested during two types of meditation: a “compassion”-oriented meditation, described as a contemplation of suffering within the world combined with an emanation of loving kindness, and “one-point” meditation, described as the maintained focus of attention on a single object or thought that leads to a stability and clarity of mind. “We found that increases in the durations of perceptual dominance were experienced by monks practicing one-point meditation, but not compassion meditation,” says Carter.

In a different test of perceptual rivalry called motion induced blindness, in this case prior to any meditation, the duration of stable perception experienced by monks averaged 4.1 seconds, compared to 2.6 seconds for meditation-naïve control participants. “Remarkably, when instructed to actively maintain the duration of perceptual stability, one of the monks who studied mediation for many years could maintain a constant visual perception during this test for 723 seconds,” says Carter. “The findings suggest that processes particularly associated with one-point meditation, perhaps involving intense attentional focus and the ability to stabilize the mind, contribute to the prolonged rivalry dominance experienced by the monks.”

Daniel: I'd have to insert petrifying potion into my eye first.
