Being forgetful might actually mean you’re smarter
    2018-04-09  08:53    Shenzhen Daily

You can relax if remembering everything is not your strong suit. Recent research makes the case that being forgetful can be a strength — in fact, selective memory can even be a sign of stronger intelligence.

Traditional research on memory has focused on the advantages of remembering everything. But looking through years of recent memory data, researchers Paul Frankland and Blake Richards of the University of Toronto found that the neurobiology of forgetting can be just as important to our decision-making as what our minds choose to remember.

“The goal of memory is not the transmission of information through time, per se. Rather, the goal of memory is to optimize decision-making. As such, transience is as important as persistence in mnemonic systems,” their study in Neuron states.

Making intelligent decisions does not mean you need to have all the information at hand. It just means you need to hold onto the most valuable information. And that means clearing up space in your memory palace for the most up-to-date information on clients and situations. Our brains do this by generating new neurons in our hippocampus, which have the power to overwrite existing memories that are influencing our decision-making.

“If you’re trying to navigate the world and your brain is constantly bringing up multiple conflicting memories, that makes it harder for you to make an informed decision,” Richards told Science Daily.

If you want to increase the number of new neurons in our brain’s learning region, try exercising. Moderate aerobic exercise like jogging, power walking, and swimming have been found to increase the number of neurons making important connections in our brains.

When we forget the names of certain clients and details about old jobs, our brain is making a choice that these details do not matter. Although too much forgetfulness can be a cause for concern, the occasional lost detail can be a sign of a perfectly healthy memory system. The researchers found that our brains facilitate decision-making by stopping us from focusing too much on minor past details.

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。

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。

他们发表在《神经元》期刊上的研究论文指出:“记忆的目的本质上不是随着时间流逝传递信息。相反,记忆的目的是优化决策。因此,记忆系统的短暂性与持久性一样重要。”

理性决策并不意味着你需要随时掌握所有信息,它仅仅意味着你需要紧紧抓住最有价值的信息。这意味着要在记忆宫殿中为最新的客户和情景信息清理出空间。大脑通过产生新的海马体神经元完成清理,海马体能够改写影响人们决策的现有记忆。

理查兹告诉《每日科学》的记者:“如果你试图应对复杂情况,而你的大脑不停地记起多种互相矛盾的记忆,那会让你难以做出明智的决策。”

如果你想增加大脑学习区域的新神经元数量,可以尝试锻炼。研究发现,诸如慢跑、健步行走和游泳这类适度的有氧锻炼可以增加大脑内部重要连接区域的神经元数量。

如果人们忘记了某些客户的姓名和原先岗位的细节,那是大脑在进行选择,认为这些细节无关紧要。虽然严重健忘可能令人担忧,但是偶尔忘记枝节小事可能表明记忆系统非常健康。研究人员发现人们的大脑通过阻止人过多关注以往的细枝末节来加强决策能力。
