anxiety and memory loss.
In order to multitask, the brain us an area known as the prefrontal cortex(前额叶脑皮层). Brain ans of volunteers performing multiple tasks together show that as they shift from task to task, this front part of the brain actually takes a moment of rest between tasks. You may have experienced a prefrontal cortex“moment of rest” yourlf if you’ve ever dialed(拨电话) a phone number and suddenly forgotten who you called when the line is answered. W
hat probably occurred is that between the dialing and the answering, your mind shifted to another thought or task, and then took that“moment” to come back. Rearch has also shown that for many volunteers, job efficiency(效率) declines while multitasking, as compared to when they perform only one task at a time.
Multitasking is easiest when at least one of the tasks is habitual, or requires little thought. Most people don’t find it difficult to eat and read the newspaper at the same time. However, when two or more attention-requiring tasks are attempted at one time, people sometimes make mistakes.
We often don’t remember things as well when we’re trying to manage veral details at the same time. Without mental focus, we may not pay enough attention to new information coming in, so it never makes it into our memory stores. That is one of the main reasons we forget people’s names—even sometimes right after they have introduced themlves. Multitasking can also affect our relationships. If someone checks their e-mail while on the phone with a friend, they may come off as abnt-minded or disi

The Cost of Higher Education
Individuals (个人) should pay for their higher education.
A university education is of huge and direct benefit to the individual.Graduates earn more than non-graduates.Meanwhile,social mobility is ever more dependent on having a degree.However,only some people have it.So the individual,not the taxpayers,should pay for it.There are pressing calls on the resources (资源) of the government.Using taxpayers’ money to help a small number of people to earn high incomes in the future is not one of them.
Full government funding (资助) is not very good for universities.Ad薰衣草精油怎么用
am Smith worked in a Scottish university who teachers lived off student fees.He knew and looked down upon 18th-century Oxford,where the academics lived comfortably off the income received from the government.Guaranteed salaries,Smith argued,were the enemy of hard work,and when the academics were lazy and incompetent,the students were similarly lazy.
If students have to pay for their education,they not only work harder,but also demand more from their teachers.And their teachers have to keep them satisfied.If that means taking teaching riously,and giving less time to their own rearch interests,that is surely something to celebrate.
Many people believe that higher education should be free becau it is good for the economy (经济).Many graduates clearly do contribute to national wealth,but so do all the business that invest () and create jobs.If you believe that the government should pay for higher education becau graduates are economically productive,you should also believe that the government should pay part of business costs.Anyone promising to create jobs should receive a gift of capital from牙膏什么牌子最好
the government to invest.
Therefore,it is the individual,not the government,who should pay for their university education.
