John: Hello everybody! Here are three memory tests. They will test how well you remember images, numbers and words.

Test 1: Visual memory test

Wendy: For the first test, look at the image for 10 seconds.

Now, cover the first image. Fill in the same pattern in the second image. 

Now look at the first picture. Did you do it right?

John: Visual memory is the ability to remember pictures, shapes, and so on.

Visual memory affects the way we learn as a lot of information we take in is visual in nature. We can improve visual memory through practice and visual games.

John: Test 2: Number memory test

For the second test, Wendy will say two sets of numbers. When she finishes, repeat the numbers after her. Here’s the first set.

Wendy: Nine-seven-five-four-seven.

John: Write the numbers down now. Next, the second set.

Wendy: Four-three-one-eight-six-two-six-two.

John: Now write it down. Wendy will read the numbers again. Listen and check your answers.

Wendy: Nine-seven-five-four-seven. Four-three-one-eight-six-two-six-two.

John: How many numbers did you get right? Most people can remember about six or seven numbers for a short time. Putting the numbers into smaller groups is a good way to remember them.

John: Test 3: Word memory test

Here’s the third test. Wendy will read out two lists of words. When she finishes, repeat the words after her. Here’s list A.

Wendy: Sit, day, pen, cow, six.

John: Now write the words down. Here’s list B.

Wendy: Man, cat, fat, hat, sat. 

John: Now write those words down. Which list was easier to remember? Yes, list A is easier. Scientists think that list B is harder because the words in list B sound similar.

答案：2 They test how well we can remember images, numbers and words.
