Kids can improve their brainpower by cooking，gardening and cleaning around the house，according to a new research. Some scientists studied 207 children aged 5 to 13 who are from Britain.They found the daily household tasks are connected with better planning，good executive（執(zhí)行的）ability and remembering instructions. The results show 86 percent of kids clean up their dirty clothes after playing，but only 59 percent make their own bed and only 26 percent sort（分類）dirty clothes. Older children are more possible to do chores than younger ones and girls do more chores than boys.Putting the dishes into the dishwasher（洗碗機(jī)）is a job for 55 percent of children. "Parents may be able to use age-and-ability-proper chores to push the development of executive abilities，"Ms.Tepper said. "Children who often cook a family meal or take care of the garden may be more possible to do well in other things - like schoolwork or problem-solving，"Ms.Tepper said. "That's because cooking for others is connected to better working memory and the ability to thin before acting，" she added.
