We usually believe what our brain tells us, but there are some amazing facts which show that the brain tricks us. As a result, we think we can see something that is not actually there or we ignore（忽視）things that actually are there.

Scientists Daniel Simons and Christopher Chabris have researched this phenomenon（現(xiàn)象）, which they call “change blindness”. Their experiments show how we sometimes just do not see what is in front of our eyes because .

Here is one of their most famous experiments. In this experiment, the participants（參與者）were shown a video of two groups of people (one group in white T-shirts and one group in black T-shirts) who passed basketballs around in a hallway. Each group had three members. Simons and Chabris asked the participants to count how many times the white team passed the ball. While the two teams were passing their balls around, a person dressed up as a big bear walked through the group and stopped to look at the camera. Simons and Chabris found that about half of the research participants did not notice the big bear.

2.How many people did the experiment need in the video?

Have you seen Avatar（《阿凡達(dá)》）? It’s a popular 3D movie, and you may have to wear 3D glasses to see it. The 3D glasses make the images(圖像)from the movie look as if they were coming straight towards you.

More and more 3D movies are coming to theaters. Some say that 3D TV sets will come into our homes in the near future. 3D technology can make TV and movies are more exciting. However, people with eye problems may get headaches if they spend too much time watching 3D movies. Why?

When we look at an object(物體), each eye sees it at a different angle(角度). Our eyes send the two images to our brain(大腦), and the brain puts them together. 3D technology uses two film projectors(投影機). One projects a left-eye-image and the other projects a right-eye-image. 3D glasses allow us to see a different image in each eye. So, when we are watching a 3D movie, our brain can’t put together the images sent to our eyes. The brain needs to work harder at “reading” the images. That makes it easier for people with eye problems to get dizzy(頭暈的) or have headaches. A famous eye doctor said if your eyes can’t focus(聚焦) on the same object at once, you will have trouble watching 3D movies.
