阅读 A ( B2P49 ) Have you ever seen something cute (可爱), like a baby dog or a baby rabbit , and just wanted to hug it to pieces ? I'm pre tt y sure you have . When you think about it , t hat urge is kind of peculiar , maybe even a little dangerous . However it turns out the "I want to hug you and squeeze you to death" urge you might feel when you set something cute is totally normal . A study done at Yale University recently explored this phenomenon and the Findings were published in Psychological Science . The experiment studied what happened when people were presented with "cute stimuli (刺激). The study found that people who have e xtremely positive reactions to cute babies also "displayed stronger aggressive expressions" . I know that sounds kind of strange , but what they're saying is that people who were really into the babies wanted to press their cheeks or maybe squeeze their slightly fat legs‘ Totally normal . Keep in mind that we're talking about an innocent little squeeze , not an urge to actually do any harm . But why does it happen ? Oriana Aragon , a scientist , says it's common for some people who experience a strong emotion to immediately express their feelings in a way that seems to be opposite to what they're feeling . Like crying when you're happy or laughing when you're sad . The same thing is going on when you want to squeeze that baby rabbit . It serves an actual biological function . According to the study , it helps reestablish your e mo t ional equilibrium . In other words , it keeps your emotions (情感) balanced . Also , if you're taking care of a baby or baby animal , your squeezing urge actually helps you be a be tt er caretaker . Aragon says , "Because they may help people to regain control over their strong emotions , these expressions help the caretaker to care for an animal or baby appropriately .
