Talking to friends on WeChat, Wang Chenchen’s mood changes according to her friends’ replies. Long sentences are always heartwarming and happy emoticons indicate the other person’s good spirits. But one word replies like “OK”, “Oh” or “hehe” quickly kill the mood.
Over-reliance on online communication is causing division between people and social anxiety in this digital era. With social media bringing people closer together than ever before, a new set of online language norms also appears.
Connected or separated
Wang Chenchen, 20, an English major at the University of International Business and Economics says, “I tend to judge my friends by the quality and speed with which they comment on my updates on Weibo or WeChat.”
But to Chen Jie, 21, a biological engineering major at Huazhong University of Science and Technology, Wang’s evaluation system is problematic. “Everyone has their lifestyle and a certain way of using social media,” says Chen, who is always busy working in the laboratory and hardly has time for social media.
Ge Yan, a professor of communication at Shanghai Jiaotong University, says social media is causing fragmentation (碎片化) of communication. “People tend to judge their surroundings by the information available,” says Ge. “They also evaluate their friendships and others’ lifestyles based on fragmented pieces of information with which they construct a so-called reality.”
Need for emotion
According to Ge, such superficial communication helps encourage more interaction between people, but in terms of building solid interpersonal relationships it causes more harm than good. An online survey on Sina Weibo last month shows, “hehe” was the top conversation killer in 2013. “The words people hate all have one thing in common — a lack of emotion,” says Ge.
Zhang Wei, a professor of linguistics at Renmin University of China, thinks that such short expressions carry so little emotion that they separate people. Chatting online cannot convey the same emotions as communication in real life. This makes it difficult to understand the other person’s true intentions. “That’s why I always suggest talking face to face to resolve problems,” says Zhang. “Unfortunately the reality is that most people spend less time talking to each other in this way.”
Anxiety and insecurity
Zhang further explains that the reason why people’s mood is strongly affected by such unemotional words when communicating online is rooted in social anxiety. People feel insecure because of all kinds of pressures. It’s like a vicious circle — “Less time for face-to-face communication leads to more online communication, but online expressions of emotion are too changeable to provide the comfort needed,” says Zhang. “As a result, people become more anxious.”
