词汇理解
Loneliness hurts. It is psychologically【C1】________and so physically unhealthy that being lonely increases the likelihood of an earlier death by 26 percent. But the feeling may serve a purpose. Scientists【C2】________that it hurts so much because, like hunger and thirst, loneliness acts as a【C3】________alarm bell. The ache of it drives us to seek out social connection just as hunger pangs urge us to eat. The idea is【C4】________satisfying, yet it has long proved difficult to test in humans.
On March 26, researchers at the Massachusetts Institute of Technology posted a preliminary report on bioRxiv. It was the first study in humans to show that both loneliness and hunger【C5】________signals deep in a part of the brain that governs very basic impulses for reward and motivation. The findings point to one telling conclusion: our need to connect is apparently as fundamental as our need to eat.
The extraordinary scientific timing of the paper\’s release—just as tens of millions of people were suddenly starved for contact in the special period of 2020—was far from intentional. When they began the work three years ago, neuroscientists Livia Tomova and Rebecca Saxe and their colleagues wanted to demonstrate how loneliness operates in the brain. They were【C6】________by similar research in animals and by the pioneering loneliness studies.
The paper, which has not yet been peer-reviewed, describes a【C7】________ designed experiment using functional magnetic resonance imaging (fMRI) to compare brain responses to loneliness and hunger. After a baseline brain scan, 40 adult participants【C8】________two 10-hour sessions: one in which they were【C9】________of food and another where they were denied social contact. The sessions served as control conditions for each other. \\
