1 .<-NARRATOR:-> Now listen to part of a lecture in a psychology class.
1 .<-MALE PROFESSOR:-> I have a three-year-old daughter, and last month I decided to help her learn how to wash her hands by herself.
1 .Now, we usually think of washing our hands as one action,
2 .but when you think about it, you can break hand washing down into a series of simpler steps:
3 .step 1, you turn on the water; step 2, you get your hands wet;
4 .step 3, you add some soap; step 4, you rinse your hands, and step 5: you turn off the water.
1 .So I broke it down into these steps, and then I helped my daughter learn them, one step at a time;
2 .I didn’t present them all at once because that would have been too complicated.
1 .First I showed her step 1, turning on the water.
2 .That’s all we practiced for the next few days.
1 .Then, when she started turning on the water by herself, I added step 2, getting her hands wet.
2 .And for the next few days she practiced steps 1and 2,
3 .turning on the water and getting her hands wet, until she could do both steps on her own.
1 .Then we added step 3, putting on the soap, and she practiced steps 1, 2, and 3 for a while.
2 .Then we added step 4, rinsing her hands, and eventually, step 5, turning off the water.
1 .She practiced all five steps in sequence for a few days until she could wash her hands all by herself.
