Are these pillars round or quadrate?
Move or not?
Count the black dots.

Why are people misled by their own eyes? Because the background or other lines confuse the eyes. Also, what we expect to see can change what we see. Actually it’s more the brain that is confused than the eyes.

How can you find out whether the two lines are of the same length? You can use a ruler to measure the two lines. Or you can use two pieces of paper to cover both ends of the two lines.

2. How do the deaf communicate with each other? They use body language or sign language.
However, even if we have good senses, they can still confuse us. Look at the following pictures and try to answer the questions.
1. Do you use one of your senses more than the others? Give an example. In the dark, the sense of hearing and the sense of touch become more sensitive because we can’t see anything. When we listen to our favorite music, we may close our eyes and just listen with our ears.
