In the blink of an eye


In the blink of an eye
We like to say that fast things happen in the blink of an eye, and neuroscientists at MIT have found that our brains can process images that we see for as little as 13 milliseconds. A new study in Attention, Perception, and Psychophysics found the first evidence of such rapid processing, as scientists had previously thought the brain required 100 milliseconds to fully process an image. The researchers asked participants to identify a specific type of image (like "picnic" or "happy couple") from a series of six to 12 images that were displayed for 13 to 80 milliseconds. The researchers began to decrease the amount of time that the pictures were displayed until the subjects' guesses were no better than chance. Although they did make more mistakes as the display time dropped, the participants still did significantly better than simple guessing. The researchers couldn't measure processing below 13 milliseconds as that was the limit of the computer monitor. The researchers believe that the brain continues to process the image long after it disappears from sight. These results show that our brain's visual processing speed is about 10 times faster than we originally thought.

  1. You can be clever with this and implement subliminal messages even more discretely than before. Both an interesting and frightening thought

  2. Interesting...indeed, frightening.. ummm nope, none, zero..

  3. Long term indoctrination, manipulation. People are influenced without them knowing. Perhaps I'm thinking too much...

  4. Well dumb creatures are everywhere we didn't need a study to tell us how to manipulate them.

  5. I think intelligent people can also be manipulated, through techniques such as misdirection (magic tricks for instance)

  6. Ummm as far as I know EQ is much more important than IQ...but doesn't hurt to have a little bit of both ;)

  7. It is good to have a mix of both, I wouldn't necessarily say one is more important than another - it depends on the situation. Also important to be self-aware and know your limits (aim to exceed them)

  8. Actually EQ is much more important than IQ..and I'll stick to that.
    But agree with ..." important to be self-aware and know your limits (aim to exceed them)"
    On that note..time to get dressed and go to opera ;)

  9. I focus on RQ: rationality quotient.

  10. Emotions, properly understood, are like precompiled subroutines that can be triggered by reference and run 50-100 times faster than contemplatively induced responses. Thinking is like running under a code interpreter ... much slower than running a precompiled module, but with the facility to break and edit as you go. This is the power and danger of emotion: if the response is correct, then the order of magnitude extra quickness of response is incredibly valuable. But when emotions are stale and thereby off track (usually because the response was encoded under different circumstances that no longer apply, but the user has not updated the module to accord with new experiences in the meantime), they mislead. I realize that this is a bare sketch of the analogy and am not presenting it here as a whole model. But I have done so in the past and could dig up my prior analysis and perhaps improve it if anyone is interested.

  11. I'd say that EQ is a subset of characteristics which comprise parts of IQ. Both are important, but if one wants to "be content" and cultivate healthy relationships, I would say that a well-developed EQ is critical.

  12. Intelligence is our ability to sort the data we experience in life. Emotion is our priority system to the way we'll respond to it all. Knowing and expression.
     
    If we can't collect information, we won't have a high IQ. If we can't prioritize and therefore chose our reactions we won't have a high EQ. But knowing how to connect the data requires prioritization. And control of your priorities requires knowledge of them. Thus entwines intellegence and emotion.
     
    There are plenty of well adjusted people without a good education. There are plenty of mal-adjusted people with doctoral degrees.
    One isn't necessarily better than the other, but they are both needed. Intelligentce and emotional control are two strands of mental DNA, that when in tact provide you with a healthy lifestyle.
     
    I will concede that emotional control is more accessable and therefore can be seen as more valuable. Great societies can be made simply by people having all the right responses to one another. No need for everyone to be college graduates. But I suppose being able to control your emotions is an intelligence of itself. Knowledge of self. See! You really can't seperate the two!
     
    Like I said. Each are part of the same mental DNA double helix.
