When you are busy with schoolwork and making friends, do you envy (羡慕) babies?
Two-year-old babies care about how others see them. They eventry to manage their image (形象) when others are around them, according to scientists from Emory University in the US.
Scientists did tests on 144 babies from the ages of 14 to 24 months.When the babies pressed the buttons, the scientists gave them different feedback (反馈).When the babies pressed the first button, the scientists would act happy and praise the baby. But when the babies pressed the second button, the scientists would frown (皱眉) and pretend to be unhappy.
They found that when there were no adults around, children would press the second button more often.
Older children and adults tend to show the same kind of behavior. When others are watching, people tend to behave better. When no one is paying attention, they behave badly.
Previous (之前的) studies found that children start to care about what others think of them around the age of 4. In addition, 2-year-old children will change their behavior to get a more positive response, Botto said.
