What is the smartest age?
0
7295
2294
哪个年龄的人最聪明?
00:09
Perhaps a day of friendly competition will lead us to the answer.
1
9589
4171
也许参加一天的友谊竞赛 会带给我答案。
00:14
Tomorrow’s the annual Brain Clash—
2
14802
2962
明天是一年一度的头脑争霸赛——
00:17
ten teams of two competing in a decathlon of mental challenges,
3
17764
3795
十个两人一组的团队 将在由智力挑战、
00:21
trivia competitions, and puzzles.
4
21559
2461
知识问答和谜题组成的 十项全能竞赛中角逐。
00:24
I’ve been training all year.
5
24020
1376
我为此准备了一年,
00:25
I’ll need to pick the smartest, most capable teammate.
6
25396
3337
需要选择最聪明、 最有能力的队友,
00:29
I’ve narrowed down the roster.
7
29192
1501
并列出几个可能的人选。
00:31
First we have Gabriela.
8
31069
2168
首先,是加芙列拉,
00:33
She may only be 8, but don’t underestimate her!
9
33237
3045
只有八岁,但别低估了她!
00:36
She’s fluent in two languages and is the ultimate outside-the-box thinker.
10
36282
4213
她能流利地说两种语言, 而且还是一个极具创造力的人。
00:41
Then there’s Ama.
11
41120
1085
其次,是埃玛,
00:42
She can recite 100 digits of pi, designs satellites for a living,
12
42205
4212
她能背诵圆周率前 100 位, 以设计卫星为生,
00:46
and bakes a perfect soufflé.
13
46417
2378
并擅长烘烤完美的蛋奶酥。
00:49
Or I could go with Mr. Taylor.
14
49462
1877
或者我可以选择泰勒先生,
00:51
He’s the best chess player in the neighborhood,
15
51339
2210
他是邻里中最好的棋手,
00:53
not to mention he’s competed in over 20 Brain Clashes
16
53549
3128
更不用说他还参加过 二十多届头脑争霸赛,
00:56
and is a five-time champion!
17
56677
2086
而且五次夺冠!
00:59
I’m not sure who to pick! Who’s the smartest?
18
59472
3378
我不确定选谁! 谁才是最聪明的?
01:05
Which of these teammates should Amir choose for tomorrow's contest and why?
19
65186
4129
阿米尔应该在明天的比赛中 选谁做队友、为何选这个人呢?
01:09
Of course, it depends.
20
69732
1627
当然,这视情况而定。
01:11
While intelligence is often associated with things like IQ tests,
21
71359
4004
虽然智力通常会和 IQ 测试挂钩,
01:15
these assessments fail to capture the scope and depth
22
75363
2878
但这些测试通常会忽略
01:18
of a person’s varied abilities.
23
78241
1918
一个人各种能力的范围以及深度。
01:20
So instead, we’ll break down the idea of “smart” into categories
24
80409
4630
因此,我们将把“聪明”的概念分为
01:25
like creativity, memory, and learning
25
85039
2628
创造力,记忆力和学习能力等类别,
01:27
and explore when the brain’s best at each of them.
26
87667
2627
并探索大脑什么时候 最擅长其中的每一项。
01:30
Let's start at the very beginning.
27
90461
1669
让我们从头开始,
01:32
In the first few years of life,
28
92130
1543
在生命中头几年,
01:33
your brain undergoes incredible rapid growth, called synaptogenesis,
29
93673
4129
你的大脑迅速成长,称为突触发生,
01:37
where more than 1 million new neural connections are formed every second.
30
97802
3879
每秒形成超过100 万个 新的神经连接。
01:42
As the brain develops, it goes through a pruning process.
31
102431
3045
随着大脑发育,它会经历修整过程,
01:45
Based on your experience and environment,
32
105852
2127
基于你的经历和所处环境,
01:47
used connections are strengthened and unused connections are removed.
33
107979
4796
使用的连接将得到加强, 未使用的连接将被删除。
01:53
Frequently used neuronal pathways are myelinated,
34
113276
3003
经常使用的神经通路有髓鞘,
01:56
wrapped in a layer of insulation, allowing information to travel faster.
35
116279
4671
包裹在一层绝缘层中, 使信息传播更快,
02:01
This creates a more efficient, fine-tuned brain.
36
121242
2920
这创造了一个更高效、精良的大脑。
02:04
But this brain remodeling happens within and between brain regions
37
124829
3670
但这种大脑重塑在不同的时间 发生在脑区内部和之间,
02:08
at different times,
38
128499
1293
使不同的技能
02:09
allowing different skills to flourish at different ages.
39
129792
2795
在不同的年龄段得到发展。
02:13
For example, in childhood, brain regions involved in language learning
40
133296
3920
比如说,在孩童时期, 大脑参与语言学习的部分
02:17
develop quickly,
41
137216
1210
发育特别迅速,
02:18
which is why many children can learn and master multiple languages.
42
138426
3754
这也就是为什么很多孩子 能够学会并掌握多种语言。
02:22
Yet the prefrontal cortex,
43
142305
1585
然而,前额叶皮层,
02:23
a brain region responsible for cognitive control and inhibition,
44
143890
3712
大脑负责认知控制和抑制的一个部分
02:27
is slower to develop.
45
147602
1710
发育缓慢,
02:29
As a result, some young children may struggle with strategic games,
46
149395
3545
因此,许多小孩可能 不擅长策略性游戏,
02:32
such as chess or checkers,
47
152940
1543
比如下象棋或跳棋,
02:34
which require constant concentration, planning, and abstract thought.
48
154483
4171
这需要持续的专注力、 计划和抽象思维。
02:38
At the same time, children tend to be more flexible, exploration-based learners.
49
158821
4713
同时,孩子们倾向于自由、 探索性的学习,
02:43
They often use more creative approaches when finding solutions to riddles
50
163743
3962
他们用更富想象力的方法解谜题,
02:47
and are, on average, less afraid to make mistakes.
51
167705
3045
而且大部分很少怕犯错。
02:51
But adults have their own unique set of abilities.
52
171125
2961
但成年人有他们独特的能力,
02:54
Adults benefit from a well-developed prefrontal cortex,
53
174462
3587
成年人得益于发达的前额叶皮层,
02:58
allowing them to better execute skills that require learning, focus, and memory,
54
178049
4254
让他们能够更好地去执行 需要学习、专注和记忆的技能,
03:02
making them quick and efficient puzzle solvers or crossword masters.
55
182303
3879
他们能够更快且高效地 解决谜题或完成填字游戏。
03:06
Late in adulthood, these same skills may decline
56
186641
2877
成年后期,随着大脑的 记忆中心海马体的萎缩,
03:09
as the brain’s memory center, known as the hippocampus, shrinks.
57
189518
3754
这些技能可能会下降。
03:13
But there’s a reason for the phrase “older and wiser.”
58
193397
3254
但我们常说 “越老越智慧” 是有据可循的,
03:16
After a lifetime of learning,
59
196943
1960
历经一生的学习,
03:18
older adults have more knowledge to recall and utilize,
60
198903
3128
年长者有更多知识可以回顾并使用,
03:22
making them excellent trivia partners.
61
202031
2544
使他们在知识问答中更具优势。
03:24
Other factors that Amir should consider are his own strengths.
62
204909
3545
阿米尔应该考虑的其他因素 包括他自己的优势,
03:28
As an adolescent, the prefrontal cortical regions of your brain are more developed
63
208454
4296
作为青少年,大脑前额叶皮质区域
03:32
than in childhood.
64
212750
1210
比儿时更加发达,
03:33
This allows you to better navigate logic and math puzzles.
65
213960
3962
这也使得你能更具逻辑、 更擅长解决数学谜题。
03:37
Simultaneously, deep inside the brain,
66
217922
2336
同时,在大脑深处,
03:40
regions that are important in motivation and reward are developing even faster,
67
220258
4546
对激励和奖励起重要 作用的区域迅速发育,
03:44
driving teenagers like Amir to be curious and adventurous learners.
68
224804
4212
促使像阿米尔这样的青少年 成为好奇、富有冒险精神的学习者。
03:49
In many ways, you can think of the teenager as a jack-of-all-trades,
69
229809
3962
在很多方面,你可以认为 青少年是一个多面手,
03:53
with brains wired to seek out new experiences and learn quickly.
70
233771
3879
他们的大脑敢于寻求 新的体验并迅速学习。
03:57
You’re at a dynamic stage,
71
237733
2044
你正处于一个动态的阶段,
03:59
where the choices you make and the skills you focus on
72
239777
3253
你所做的选择和你所关注的技能
04:03
can actually guide the development of your brain.
73
243030
3170
实际上可以指导你大脑的发展。
04:06
So, what’s the smartest age?
74
246784
2169
那么,哪个年龄段的人最聪明呢?
04:09
There’s no single answer.
75
249203
2169
没有唯一的答案。
04:11
It’s 8, 16, 25, 65, and everything in between;
76
251580
4505
可以是 8 岁、16 岁、25 岁、 65 岁, 以及中间的任意年龄;
04:16
our brains have adapted to prioritize different skills at various ages
77
256502
4087
我们大脑在人生不同阶段 关注发展不同的技能,
04:20
to meet that stage of life’s challenges and demands.
78
260589
3337
以应对生活中相应的挑战和需求。
04:24
So no matter who Amir picks, having an age-diverse team is a good strategy.
79
264468
5005
所以不管阿米尔选择谁, 拥有一个跨年龄段的团队才是好策略。
