Ever wonder why overhearing a cellphone conversation is so annoying? American researchers think they have found the answer. Whether it is the office, on a train or in a car, only half of the conversation is overheard which draws more attention and concentration than when overhearing two people talking, according to scientists at Cornell University. "We have less control to move away our attention from half a conversation (or halfalogue) than when listening to a dialogue," said Lauren Emberson, a co-author of the study that will be published in the journal Psychological Science. "Since halfalogues really are more distracting and you can't tune them out, this could explain why people are irritated," she said in an interview. Last year Americans spent 2.3 trillion minutes chatting on cellphones, according to the US wireless trade association CTIA -- a ninefold increase since 2000. Worldwide, there are about 4.6 billion cellphone subscribers, according to the International Telecommunications Union, a U.N. agency. The number is equal to about two-thirds of the world's population, leaving few corners of the globe where public spaces are free of mobile-tethered babblers. China has the most cellphone users with 634 million, followed by India with 545 million and the United States with 270 million, figures from the U.S. Central Intelligence Agency (CIA) show. Emberson said people try to make sense of snippets of conversation and predict what speakers will say next. "When you hear half of a conversation, you get less information and you can't predict as well," she said. "It requires more attention." The findings by Emberson and her co-author Michael Goldstein are based on research involving 41 college students who did concentration exercises, like tracking moving dots, while hearing one or both parties during a cellphone conversation.

知道為什么聽(tīng)別人打手機(jī)如此心煩嗎？美國(guó)研究人員稱他們找到了答案。 康奈爾大學(xué)的科研人員稱，無(wú)論在辦公室、火車還是汽車上，只聽(tīng)到一半的手機(jī)談話比聽(tīng)兩個(gè)人的完整對(duì)話更耗費(fèi)注意力和精力。 將在《心理科學(xué)》雜志上發(fā)表的研究報(bào)告的撰寫(xiě)者之一勞倫?艾伯森說(shuō)：“相對(duì)于傾聽(tīng)一段完整的談話，只聽(tīng)到一半的談話讓我們更難以轉(zhuǎn)移注意力。” 她在采訪中說(shuō)：“‘一半的談話’的確更易讓人分神，而你又不能不聽(tīng)，這可以解釋為什么聽(tīng)別人打手機(jī)會(huì)心煩。” 據(jù)美國(guó)無(wú)線貿(mào)易組織電信工業(yè)協(xié)會(huì)的數(shù)據(jù)顯示，去年美國(guó)人打手機(jī)聊天的時(shí)間達(dá)2.3萬(wàn)億分鐘，比2000年增加了九倍。 據(jù)聯(lián)合國(guó)國(guó)際電信同盟的數(shù)據(jù)顯示，目前全世界約有46億手機(jī)用戶，占全球總?cè)丝诘娜种謾C(jī)用戶幾乎遍布世界的每個(gè)角落。 美國(guó)中央情報(bào)局的數(shù)據(jù)顯示，中國(guó)的手機(jī)用戶最多，達(dá)6.34億，其次是印度，為5.45億，美國(guó)位居第三，為2.7億。 艾伯森說(shuō)，在聽(tīng)別人打手機(jī)時(shí)，人們總想弄清說(shuō)話人所說(shuō)的只言片語(yǔ)的意思，并預(yù)測(cè)說(shuō)話人接下來(lái)會(huì)說(shuō)什么。 她說(shuō)：“當(dāng)你只聽(tīng)到一半的談話時(shí)，你得到的信息較少，也不好去預(yù)測(cè)，所以需要更多的注意力。” 艾伯森和研究報(bào)告的共同撰寫(xiě)人邁克爾?戈德斯坦讓41名大學(xué)生做了一項(xiàng)注意力練習(xí)，比如讓他們?cè)诼?tīng)一個(gè)人或兩人在進(jìn)行手機(jī)談話時(shí)追蹤移動(dòng)的小圓點(diǎn)。他們的研究發(fā)現(xiàn)基于這項(xiàng)測(cè)試。 相關(guān)閱讀 聯(lián)合國(guó)禁止其工作人員開(kāi)車時(shí)打手機(jī) 英國(guó)新首相有新規(guī) 禁止開(kāi)會(huì)打手機(jī) 聯(lián)合國(guó)報(bào)告：印度廁所不如手機(jī)普及 日本：十大不當(dāng)乘車行為 大聲說(shuō)話居首 調(diào)查：美國(guó)人有哪些手機(jī)禮節(jié)？ 手機(jī)依賴癥全球蔓延 離開(kāi)手機(jī)無(wú)法生活 （中國(guó)日?qǐng)?bào)網(wǎng)英語(yǔ)點(diǎn)津 陳丹妮 編輯蔡姍姍） |
