6 . A study found that adolescents with early parental set bedtimes were significantly less likely to suffer from depression, suggesting that early bedtimes could have a protective effect by lengthening sleep.
Results show that adolescents with parental set bedtimes of midnight or later were 24% more likely to suffer from depression than adolescents with parental set bedtimes of 10 pm or earlier. Adolescents who reported that they usually sleep for five or fewer hours per night were more likely to suffer from acute muscle pains, dizziness, nausea and headaches than those who reported getting eight hours of nightly sleep. Participants who reported that they “usually get enough sleep” were less irritable than those who didn't.①
James E. Gangwisch, assistant professor at Columbia University Medical Center, said that the results strengthen the argument that short sleep duration could play a role in the study of depression causes. “Our results are consistent with the theory that inadequate sleep is a risk factor for depression, working with other risk and protective factors through multiple possible causal pathways to the development of this mood disorder,” said Gangwisch, “Adequate quality sleep could therefore be a preventative measure against depression.”②
From the data collected, it was found that some participants suffered from memory loss and hallucinations.③These were associated with later parental set bedtime, shorter sleep duration, and self-perception of not getting enough sleep.
The average adolescent—reported sleep duration was
The authors of the study reported that there are a number of potential methods by which constant partial sleep deprivation could contribute to depression. Lack of sleep may produce moodiness that hinders the ability to cope with daily stresses, damage relationships with peers and adults, and affect judgment, concentration and impulse control. They also suggested that behavioral interventions that involve educating adolescents and their parents about healthier sleep practices and helping them modify sleep habits could serve as the main preventative measures against depression.

7 . Have you ever wondered how the trainers at Sea World get the 19,000-pound whale to jump 22 feet out of water and perform tricks? They get that whale to go over a rope farther out of the water than most of us can imagine.
So how do the trainers at Sea World do it? The first thing they do is reinforce(强化) the behavior that they want repeated --- in this case, to get the whale to go over the rope.
Positive reinforcement is the key of that simple principle that produces such splendid results. And as the whale begins to go over the rope more often than under, the trainers begin to raise the rope. It must be raised slowly enough so that the whale doesn’t starve.
So we need to set up the circumstances so that people can’t fail. Over-celebrate, under-criticize…and know how far to raise the rope.
A.This is a great challenge |
B.And the whale stays right where it is |
C.If we figure out a way to motivate the whale |
D.They start with the rope below the surface of the water |
E.If we under-criticize, punish and discipline less than expected |
F.Whales are taught that their negative behavior won’t be acknowledged |
G.The simple lesson to be learned from the whale trainers is to over-celebrate |
