13、at we know that the two come together, but not that whether one causes the other. In the current study, Krizan and coauthor Garrett Hisler, an ISU doctoral student, deal with this question.Under the study, volunteers were divided into two groups. The control group followed their normal sleep routine

14、, while the experimental group cut two to four hours of sleep each night for two nights. On average, the control group got almost seven hours of sleep a night, while the experimental group got about four and a half hours each night.In order to measure anger, they had volunteers visit the lab before

15、and after the sleep manipulation (操纵). All the while, they were asked to listen to some unpleasant brown and white noise.

22、 to fear. Once a rider has been physically hurt, it will take him/her a while to rebuild confidence. The old idea promised that if you just got right back on again, everything would be fine. However, suppressing (抑制) fear seldom works. Besides, suppressing fear doesnt help to tell the rider to “just

23、 get over it”Fear is usually related to the riders skill level. The best way to overcome riding fears is to work on developing good riding skills.
