That people often experience trouble sleeping in a different bed in unfamiliar surrounding is a phenomenon known as the "first-night" effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.
Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was that benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university’s Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants’ brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球)of their brains did not sleep nearly as deeply as their right hemispheres did.
Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声)of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found. [br] What did researchers find puzzling about the first-night effect?
选项
A、To what extent it can trouble people.
B、What role it has played in evolution.
C、What circumstances may trigger it.
D、In what way it can be beneficial.
答案
D
解析
细节题。根据题干关键词puzzling、the first-night effect定位到第二段第二句The puzzle was that benefit would be gained from it when performance might be affected the following day(令他困惑的是,初夜效应可能会导致人们第二天没有好的表现,那它又能带来什么好处呢?)。故D项“产生什么好处”符合题意。A项“它给人带来麻烦”,B项“它在进化过程中扮演怎样的角色”和C项“怎样的环境会刺激它”均不是佐木博士感到困惑之处。
