College Night Owls Have Lower Grades
College students who are morning people tend to get better grades than those who are nightowls(晚睡的人), according to ,University of North Texas researchers.
They had 824 undergraduate(大学本科生的)students complete a health survey that included questions about sleep habits and daytime functioning, and found that students who are morning people had higher grade point averages (GPAs) than those who are night people.
"The finding that college students who are evening types have lower GPAs is a very important finding, sure to make its way into undergraduate psychology texts in the near future, along with the research showing that memory is improved by sleep," study co-author Daniel J. Taylor said in a prepared statement.
"Further, these results suggest that it might be possible to improve academic performance by using chronotherapy(时间疗法) to help students retrain their biological clock to become more morning types, "Taylor said.
The research was expected to be presented Monday at SLEEP, the annual meeting of the Associated Professional(专业的) Sleep Societies, in Baltimore.
In other findings expected to be heard at the meeting, University of Colorado researchers found a significant association between insomnia (失眠)and a decline in college students&39; academic performance.
The study included 64 psychology, nursing and medical students, average age 27.4 years, who were divided into two groups--low GPAs and high GPAs.
Among those with low GPAs,69.7 percent had trouble falling asleep,53.1 percent experienced leg kicks or twitches (痉挛)at night,65.6 percent reported waking at night and having trouble falling back to sleep, and 72.7 percent had difficulty concentrating during the day.
"In college students, the complaint of difficulty concentrating during the day continues to have a considerable impact on their ability to succeed in the classroom," study author Dr. James F．Pagel said in a prepared statement. "This study showed that disordered sleep has significant harmful effects on a student&39;s academic performance, including GPAs."
In the first study， students who stay up late__________. 查看材料
1 Architecture is to building as literature is to the printed word. The best buildings are often so well constructed that they outlast their original use. They then survive not only as beautiful objects, but as documents of the history of cultures. These achievements are never wholly the work of individuals. Architecture is a social art.
2 The renaissance brought about an entirely new age, not only in philosophy and literature but in the visual arts as well. In architecture, the principles and styles of ancient Greece and Rome were brought back to life and reinterpreted. They remain dominant until the 20th century.
3 Many kinds of stone are used as building materials. Stone and marble were chosen for important monuments because they are not burnable and can be expected to endure. Stone architecture was often blended with stone sculpture. The use of stone has declined, however, because a number of other materials are more adaptable to industrial use.
4 The complexity of modem life calls for a variety of buildings, More people live in mass housing and go, to work in large office buildings; they spend their income in large shopping centers, send their children to many different kinds of schools, and when they are sick they go to specialized hospitals and clinics. All these different types of buildings accumulated experiences needed by their designers.
5 By the middle of the 20th century, modem architecture, which was influenced by new technology and mass production, was dealing with increasingly complex social needs. Important characteristics of modem architectural works are expanses of glass and the use of reinforced concrete. Advances in elevator technology, air conditioning, and electric lighting have all had important effects.
