研究：选择性记忆代表智商更高 偶尔健忘有益健康
<p>上周刚见过的人，这周又不记得叫什么名字了。总爱忘事儿让人烦恼，然而最新研究表明，健忘可能是优点。大脑选择性的记忆能让你做出更明智的决策，也体现出你的高智商。</p><p><span word="You">You</span> <span word="can">can</span> <span word="relax">relax</span> <span word="if">if</span> <span word="remembering">remembering</span> <span word="everything">everything</span> <span word="is">is</span> <span word="not">not</span> <span word="your">your</span> <span word="strong">strong</span> <span word="suit">suit</span>. <span word="Recent">Recent</span> <span word="research">research</span> <span word="makes">makes</span> <span word="the">the</span> <span word="case">case</span> <span word="that">that</span> <span word="being">being</span> <span word="forgetful">forgetful</span> <span word="can">can</span> <span word="be">be</span> <span word="a">a</span> <span word="strength">strength</span> — <span word="in">in</span> <span word="fact">fact</span>, <span word="selective">selective</span> <span word="memory">memory</span> <span word="can">can</span> <span word="even">even</span> <span word="be">be</span> <span word="a">a</span> <span word="sign">sign</span> <span word="of">of</span> <span word="stronger">stronger</span> <span word="intelligence">intelligence</span>.</p><p>如果事事牢记不是你的强项，你可以放心了。最新研究表明，健忘可能是个优点。事实上，选择性记忆甚至可能表明智商更高。</p><p><span word="Traditional">Traditional</span> <span word="research">research</span> <span word="on">on</span> <span word="memory">memory</span> <span word="has">has</span> <span word="focused">focused</span> <span word="on">on</span> <span word="the">the</span> <span word="advantages">advantages</span> <span word="of">of</span> <span word="remembering">remembering</span> <span word="everything">everything</span>. <span word="But">But</span> <span word="looking">looking</span> <span word="through">through</span> <span word="years">years</span> <span word="of">of</span> <span word="recent">recent</span> <span word="memory">memory</span> <span word="data">data</span>, <span word="researchers">researchers</span> <span word="Paul">Paul</span> <span word="Frankland">Frankland</span> <span word="and">and</span> <span word="Blake">Blake</span> <span word="Richards">Richards</span> <span word="of">of</span> <span word="the">the</span> <span word="University">University</span> <span word="of">of</span> <span word="Toronto">Toronto</span> <span word="found">found</span> <span word="that">that</span> <span word="the">the</span> <span word="neurobiology">neurobiology</span> <span word="of">of</span> <span word="forgetting">forgetting</span> <span word="can">can</span> <span word="be">be</span> <span word="just">just</span> <span word="as">as</span> <span word="important">important</span> <span word="to">to</span> <span word="our">our</span> <span word="decision">decision</span>-<span word="making">making</span> <span word="as">as</span> <span word="what">what</span> <span word="our">our</span> <span word="minds">minds</span> <span word="choose">choose</span> <span word="to">to</span> <span word="remember">remember</span>.</p><p>传统上有关记忆的研究一直专注于牢记不忘的优势。但是，通过最近几年统计的记忆数据，加拿大多伦多大学的研究人员保罗•弗兰克兰和布莱克•理查兹发现，就决策而言，与遗忘有关的神经生物学同大脑选择牢记不忘同等重要。</p><p>“<span word="The">The</span> <span word="goal">goal</span> <span word="of">of</span> <span word="memory">memory</span> <span word="is">is</span> <span word="not">not</span> <span word="the">the</span> <span word="transmission">transmission</span> <span word="of">of</span> <span word="information">information</span> <span word="through">through</span> <span word="time">time</span>, <span word="per">per</span> <span word="se">se</span>. <span word="Rather">Rather</span>, <span word="the">the</span> <span word="goal">goal</span> <span word="of">of</span> <span word="memory">memory</span> <span word="is">is</span> <span word="to">to</span> <span word="optimize">optimize</span> <span word="decision">decision</span>-<span word="making">making</span>. <span word="As">As</span> <span word="such">such</span>, <span word="transience">transience</span> <span word="is">is</span> <span word="as">as</span> <span word="important">important</span> <span word="as">as</span> <span word="persistence">persistence</span> <span word="in">in</span> <span word="mnemonic">mnemonic</span> <span word="systems">systems</span>,” <span word="their">their</span> <span word="study">study</span> <span word="in">in</span> <span word="Neuron">Neuron</span> <span word="states">states</span>.</p>
