When a person tries to access a memory, their brains quickly examine everything stored in it to find the relevant information.
当一个人试图提取记忆时,他们的大脑会迅速检查其中存储的所有内容以找到相关信息。
But as we age, many of us have difficulty retrieving memories.
但随着年龄增长,我们许多人在回忆时会遇到困难。
In a review published in the Journal Trends in Cognitive Sciences on february 11th, researchers propose an explanation for why this might be happening.
在2月11日发表于《认知科学趋势》杂志(Trends in Cognitive Sciences)的一篇综述中,研究人员提出了一个解释,说明为什么会发生这种情况。
The brains of older adults allocate more space to accumulated knowledge and have more material to navigate when attempting to access memories.
老年人的大脑为累积的知识分配了更多空间,因此在尝试提取记忆时,需要筛选更多的材料。
While this wealth of prior knowledge can make memory retrieval challenging, the researchers say it has its upsides.
虽然这种丰富的先前知识可能使记忆提取变得困难,但研究人员表示它也有其优点。
This life experience can aid with creativity and decision making.
这种生活经验有助于创造力和决策。
Researchers Tarik Ammer, Jodana Win and Lynn Hasher looked at several behavioral and brain imaging studies,
研究人员塔里克·阿默(Tarik Ammer)、乔达娜·温(Jodana Win)和林恩·哈舍(Lynn Hasher)查阅了几项行为和脑成像研究,
which show that older adults have difficulties suppressing information that is no longer relevant,
这些研究表明:老年人难以抑制不再相关的信息,
and that when searching for a specific memory, they often retrieve other irrelevant memories along with it.
并且在搜索特定记忆时,他们经常同时提取出其他无关的记忆。
The studies also showed that when given a cognitive task, older adults rely more heavily on previous knowledge than younger adults do.
研究还表明,当面临认知任务时,老年人比年轻人更依赖先前的知识。
While the researchers focused primarily on the difficulties that these disorderly, crowded memories may pose,
虽然研究人员主要关注这些混乱、拥挤的记忆可能带来的困难,
they also highlight a few situations in which these same memory patterns may be useful.
但他们也强调了几种情况下,这些相同的记忆模式可能是有用的。
Evidence suggests that older adults show preserved and at times enhanced creativity as a function of enriched memories,The researchers write.
研究人员写道:“有证据表明,老年人凭借其丰富的记忆,其创造力得以保持,有时甚至有所提升。”
they further hypothesize that older adults may be well served by their prior knowledge when it comes to decision making, where they can pull on their accumulated wisdom.
他们进一步推测,在决策方面,老年人可能会因其先前的知识而受益,因为他们可以运用其积累的智慧。
