1 次の英文を読み. 下記の設問に日本語で答えなさい。
Researchers from *IUC Berkeley have conducted an experiment and determined that sleep deprivation
makes it more difficult for people to accurately read facial expressions.
"The 18 young adults in the experiment viewed 70 facial expressions while fully rested and in the exhausted
state after being awake 24 hours. Researchers scanned participants' brains through functional Magnetic
Resonance Imaging (*fMRT) and measured their heart rates as they ooked at the images.
"The findings revealed that sleep-deprived brains could not distinguish between threatening and friendly faces.
"The heart rates of sleep-deprived study participants also did not respond in a normal manner to threatening or
friendly facial expressions. The sleep-deprived participants also interpreted more faces 一 even those with
friendly or neutral expressions 一 as threatening
The researchers note that this reduced abihity to recognize expressions could have serious consequences if the
sleep-deprived person does not notice a potential *3mugger or violent **predator approaching or 下 a child is sick
or in pain. In less serious situations it may make the sleep-deprived person more *'irritable 下they have trouble
telling colleagues or friends are being serious or joking.
Matthew Walker, a professor of psychology and neuroscience at UC Berkeley, says, "Tnsuffcient sleep removes
the rose tint to our emotional world, causing an overestimation of threat. This may explain why people who
report getting too ittle sleep are less social and more lonely"
Walker also says in a statement, “Recognizing the emotional expressions of someone else changes everything
about whether or not you decide to interact with them。 and in return。 whether they interact with you. These
fndings are especially worrying considering that two-thirds of people in the developed nations fail to get
sufcient sleep”
