Video: US scientists unveil new IQ measure: take the test The study, published in the Current Biology journal, claims that people with a higher IQ are better at filtering out distractions, allowing them to focus on the task in hand. Dr Tadin said their was no real average score because the ability to perceive the movement depends on the lighting conditions in the room and the resolution of the screen, but you could test yourself in relation to a colleague who was using the same computer because the conditions would be the same. How to take the test: First extend your hand with your thumb point upwards. Close one eye and adjust your distance from the screen so your thumb roughly covers the small grey square in the video. Then you will see films of bars moving either towards the left or towards the right. The number before film indicates the number of frames in the film. How many frames does it take you to see clearly the direction of the motion bars for the small bars? And how many frames does it take you to see clearly the direction of the motion bars for the large bars? And In case you were wondering: Each of the animations alternates in the direction of the lines. At two frames the lines were moving right, at three frames the lines were moving left and so on through to twenty frames when they were moving left. How early did you spot the direction of the lines? Now pass on to a friend.
