The Internet is becoming our main source of memory instead of our own brains, a study has concluded.

In the age of Google, our minds are adapting so that we are experts at knowing where to find information even though we don’t recall what it is.

The researchers found that when we want to know something we use the Internet as an ‘external memory’ just as computers use an external hard drive.

Nowadays we are so reliant on our smart phones and laptops that we go into ‘withdrawal when we can’t find out something immediately’.

And such is our dependence that having our Internet connection severed is growing ‘more and more like losing a friend’.

Researchers from Harvard University, the University of Wisconsin-Madison and Columbia University in the US carried out four tests to check their theory.

They involved giving test participants a trivia quiz and then seeing whether they recognised computer-related words more quickly than other words.

The other tests involved seeing if people remembered 40 pieces information they would typically later have normally looked up.

The third and fourth parts of the study involved checking how well people remember where to look up information on-line and whether or not they remembered the location more than the actual data.

The results showed that when people don’t believe they will need information for a later test, they do not recall it at the same rate as when they do believe they will need it.

In fact, some of those in the study ‘actively did not make the effort to remember when they thought they could later look up the trivia statements they had read’, the paper says.

The other results showed that when continuous Internet access is expected, people are better at remembering where they can find it than the details.

一項(xiàng)研究得出結(jié)論稱(chēng)，網(wǎng)絡(luò)正取代人腦成為記憶的主要存儲(chǔ)庫(kù)。

我們的大腦正逐漸適應(yīng)谷歌時(shí)代，就算我們記不起某一信息，我們卻善于從網(wǎng)絡(luò)中找出這一信息。

研究人員發(fā)現(xiàn)，當(dāng)我們想知道某一事物時(shí)，我們就會(huì)將網(wǎng)絡(luò)作為一種“外存”，就像電腦使用外部硬盤(pán)驅(qū)動(dòng)器一樣。

如今我們是如此依賴于我們的智能手機(jī)和筆記本電腦，當(dāng)我們“無(wú)法立刻找出某一信息時(shí)，我們的生活甚至?xí)�停擺”。

我們也非常依賴于網(wǎng)絡(luò)，如果我們的網(wǎng)絡(luò)連接中斷了，我們會(huì)“越來(lái)越覺(jué)得像失去了一個(gè)朋友”。

來(lái)自美國(guó)哈佛大學(xué)、威斯康星大學(xué)麥迪遜分校和哥倫比亞大學(xué)的研究人員為了驗(yàn)證他們的理論，開(kāi)展了四項(xiàng)測(cè)試。

這些測(cè)試包括讓參與者做瑣碎記憶測(cè)試，看他們是否能更快識(shí)別和電腦相關(guān)的詞匯。

其他的測(cè)試包括觀察人們是否能記住40條他們一般稍后會(huì)查閱的信息。

研究的第三和第四部分包括查看人們是否能很好地記住查閱信息的網(wǎng)站，以及他們是否對(duì)網(wǎng)站比對(duì)信息本身記得更清楚。

結(jié)果顯示，當(dāng)人們認(rèn)為自己在稍后的測(cè)試中不需要該信息時(shí)，他們能回憶起來(lái)的信息比認(rèn)為自己稍后將需要該信息時(shí)要少。

該研究報(bào)告稱(chēng)，事實(shí)上，部分參與研究的人“沒(méi)有積極努力地去記住他們所看到的信息，因?yàn)樗麄冋J(rèn)為稍后可以查閱到這些瑣碎信息”。

其他研究結(jié)果顯示，當(dāng)人們期待可以持續(xù)地連接到互聯(lián)網(wǎng)時(shí)，人們更善于記住找到信息的地方而非信息的細(xì)節(jié)。
