article imageStudy: This test of 'Motion Quotient' predicts your IQ (Video)

This video administers a simple test which researchers at the University of Rochester say they have devised to predict IQ. Watch video clips of black and white bars moving across the screen and try to determine which direction the bars are moving.
Images of different sizes were presented on the screen and the researchers measured the time it took for participants to register the direction in which the bars moved. According to the researchers, because the brain is able to filter out background movement most people find it difficult to see movement in the larger images.
Melnick and his colleagues, in a paper titled: "A Strong Interactive Link between Sensory Discrimination and Intelligence," published in the journal Current Biology, found that people with higher IQs were the worst at seeing movement in the large images, that is, they performed best at filtering out distracting sensory signals. They found that the simple visual test was a very good predictor of the performance of participants in standardize intelligence or IQ tests.
Generally, people with higher IQs are quicker at processing sensory stimuli. However, the researchers argued that processing speed alone could be a poor match for information processing demands on the brain system.
They pointed out that because the brain handles massive amounts of information its efficiency is fundamentally constrained by ability to suppress irrelevant information.
The test above was designed to demonstrate that performance in simple visual discrimination tests that reflect processing speed as well as perceptual suppression strongly correlates with IQ. High-IQ individuals are quick at perceiving small moving objects but exhibit significant impairments in perceiving motion as stimulus size increases.
The study thus links intelligence with low-level sensory perception of large moving patterns that are ecologically less relevant.
What this means is that if you could visually capture the movement of the bars in the larger images you are probably of relatively low IQ, but if you couldn't you are probably of high IQ.
So take the test and tell us what you see, honestly.
