People, who have high IQ scores, are not just more intelligent than others but also process sensory information differently, according to a research.
The findings of the research show that their brains are more selective when it comes to perceiving objects in motion and are likely to suppress larger and less relevant background motion.
Duje Tadin of the University of Rochester said that it is not that people with high IQ are simply better at visual perception, instead, he claimed that their visual perception is more discriminating.
He said that these people excel at seeing small, moving objects but struggle in perceiving large, background-like motions.
The discovery was made by asking people to watch videos showing moving bars on a computer screen.
Their task was to state whether the bars were moving to the left or to the right. The researchers measured how long the video had to run before the individual could correctly perceive the motion.

The results show that individuals with high IQ can pick up on the movement of small objects faster than low-IQ individuals can, which wasn't unexpected but the surprise came when tests with larger objects showed just the opposite: individuals with high IQ were slower to see what was right there in front of them.
The study has been published in the Cell Press journal Current Biology.
