Your brain sees things you don't

    A doctoral candidate in the UA's Department of Psychology in the College of Science, Sanguinetti showed study participants a series of black silhouettes, some of which contained meaningful, real-world objects hidden in the white spaces on the outsides. Saguinetti worked with his adviser Mary Peterson, a professor of psychology and director of the UA's Cognitive Science Program, and with John Allen, a UA Distinguished Professor of psychology, cognitive science and neuroscience, to monitor subjects' brainwaves with an electroencephalogram, or EEG, while they viewed the objects.

    "We were asking the question of whether the brain was processing the meaning of the objects that are on the outside of these silhouettes," Sanguinetti said. "The specific question was, 'Does the brain process those hidden shapes to the level of meaning, even when the subject doesn't consciously see them?"

    The answer, Sanguinetti's data indicates, is yes.

    Study participants' brainwaves indicated that even if a person never consciously recognized the shapes on the outside of the image, their brains still processed those shapes to the level of understanding their meaning.

    "There's a brain signature for meaningful processing," Sanguinetti said. A peak in the averaged brainwaves called N400 indicates that the brain has recognized an object and associated it with a particular meaning.

    "It happens about 400 milliseconds after the image is shown, less than a half a second," said Peterson. "As one looks at brainwaves, they're undulating above a baseline axis and below that axis. The negative ones below the axis are called N and positive ones above the axis are called P, so N400 means it's a negative waveform that happens approximately 400 milliseconds after the image is shown."

    The right side of the brain processes in 3-D, while the left brain processes in 2-D. One would expect the right brain, which is less conscious in most people, to look at the entire 3-D picture and not just the part we normally associate (2-D cause and effect) with the "lettering". The 3-D processing is much faster and more comprehensive. When modern human consciousness evolved about 6-10K, it did so by slowing down the speed of the processing via migration into the left brain. Now we could stop to smell the roses. The pre humans before 6-10 K years ago were more 3-D and therefore were optimized into the simplicity of instinct; too fast to differentiate as easy.

    wellwisher, why do you make up stuff like this ass pass it off as fact?

    It's good to have ideas about how things might be... but things you make up are obviously probably not true, and it is wrong to present unverified ideas as truth.
