據(jù)國(guó)外媒體4月21日?qǐng)?bào)道，最新一項(xiàng)研究表明,，電腦益智游戲并不能令我們思維敏捷,，提高智力水平。
英國(guó)劍橋大學(xué)研究人員表示,，盡管通過(guò)不斷練習(xí),，我們更善于處理復(fù)雜的電腦游戲，但沒(méi)有證據(jù)證明這在日常生活中會(huì)有作用,。專家表示,，身體健康的中年人只要多吃沙拉、經(jīng)常散步以及多跳交際舞,，這種生活方式對(duì)提高他們的智力水平大有裨益,。
妮可·基德曼、帕特里克·斯圖爾特等名人對(duì)益智游戲的支持令其成為一個(gè)價(jià)值數(shù)百萬(wàn)英鎊的產(chǎn)業(yè),，不過(guò),，對(duì)益智游戲效果的一系列研究卻帶來(lái)與之相矛盾的結(jié)果。針對(duì)外界有關(guān)算術(shù),、記憶力和邏輯推理方面的簡(jiǎn)單智力測(cè)驗(yàn)有助人們思維敏捷,，甚至有助預(yù)防老年癡呆癥的說(shuō)法，劍橋大學(xué)的研究人員尋求獲得一個(gè)明確的答案,。
他們與英國(guó)廣播公司(BBC)“理論大爆炸”節(jié)目組合作,，讓超過(guò)1.1萬(wàn)名年齡在18歲至60歲之間的健康男女志愿者完成一系列高敏感度的記憶力測(cè)驗(yàn)。按照研究設(shè)置,，一些志愿者玩許多益智游戲,，每天十分鐘，每周三次。其他志愿者則要解決一系列常識(shí)性問(wèn)題,，并要求他們上網(wǎng)查找答案,。6周以后，所有志愿者再次完成最初的記憶力測(cè)驗(yàn),。測(cè)驗(yàn)結(jié)果表明,，那些上網(wǎng)查找答案的志愿者的成績(jī)即便不突出，但與玩益智游戲志愿者的成績(jī)也一樣,。研究結(jié)果刊登在最新一期的《自然》雜志上,。(生物谷Bioon.com)

‘Brain training’, or the goal of improved cognitive function through the regular use of computerized tests, is a multimillion-pound industry1, yet in our view scientific evidence to support its efficacy is lacking. Modest effects have been reported in some studies of older individuals2, 3 and preschool children4, and video-game players outperform non-players on some tests of visual attention5. However, the widely held belief that commercially available computerized brain-training programs improve general cognitive function in the wider population in our opinion lacks empirical support. The central question is not whether performance on cognitive tests can be improved by training, but rather, whether those benefits transfer to other untrained tasks or lead to any general improvement in the level of cognitive functioning. Here we report the results of a six-week online study in which 11,430 participants trained several times each week on cognitive tasks designed to improve reasoning, memory, planning, visuospatial skills and attention. Although improvements were observed in every one of the cognitive tasks that were trained, no evidence was found for transfer effects to untrained tasks, even when those tasks were cognitively closely related.
