Hi, today I'm going to talk about cognitive load theory or cognitive overload,
2
which is a new theory on learning about how the sort of intrinsic
3
or even extraneous difficulty of a learning task impacts our ability to learn, to remember, to retrieve information and so forth.
4
And I want to give you my perspective on this
5
because I think it's quite interesting and it kind of touches on something that I've talked about before.
6
In its essence, I feel that cognitive load theory is about how do you make the task easier, essentially.
7
And the way you make a learning task easier as it applies to languages is to activate prior knowledge.
8
In other words, if you can learn something that you kind of in a way already know, it's going to be easier to learn that.
9
And if it's easier, you're going to be happier and more satisfied with the learning process, and you'll probably stay with the task.
10
I've often said that language learning is a sort of a reiterative or an iterative process.
11
You learn it once, you forget, you go back again.
12
I've used the metaphor of my lawnmower, where if the grass of my lawn is very high, I will actually set the blaze a little higher, an inch or so higher,
13
so that my first pass through the grass will be easier, and then my second pass will also be easier, and I'll have the same grass,
14
but i'll have walked through the lawn twice with a little effort as opposed to pushing against
15
much more resistance another example i used is cross -country skiing
16
if it's snowing and you're going through tracks
17
that have already been made by a skier ahead of you even
18
if more snow has fallen on these tracks you're now gliding more easily it's more comfortable you're moving faster
19
and so you're also taking advantage of in a way prior work
20
or prior knowledge again i think a lot of these education experts have a tendency to overcomplicate things
21
so they talk about the effect of cognitive overload on your short -term memory
22
or working memory and retrieving and those are a lot of details
23
that i don't fully understand but i can use my brain without knowing these things
24
if i have a learning system and process
25
that works i don't need to know in great detail how
26
that all functions in my brain i don't need to know how my car works in order to drive my car.
27
So one of the things that I have found is that prior knowledge, in other words, my previous exposure to a language, however imperfectly I remember that,
28
however many gaps there are, it's all good.
29
So if I, for example, I'm listening to a podcast in Persian and there's lots there that I don't understand,
30
and I'm really only picking up certain chunks of words and phrases that I'm quite comfortable,
31
that almost naturally understand, but I can't tie them all together to really understand the whole podcast, that is still good exposure.
32
So that creates a sort of prior knowledge.
33
Then when I go to link and I start clicking on these words to see what they mean, then I already have that first pass through,
34
that first pass with a lawnmower that makes the second pass easier.
35
It still doesn't guarantee that the next time I listen to it, I'm going to understand it all.
36
It's all a gradual buildup through this iterative and reiterative and going back again process,
37
which I think is the way to reduce the cognitive burden.
38
Another sort of extraneous factor in cognitive overload is how enjoyable the task is.
39
So if I am listening to something that's too difficult, that's not enjoyable.
40
But on the other hand, if I'm listening to something that is of no interest to me, that's also not enjoyable.
41
So as I've said before, if I'm dealing with content that is intrinsically interesting to me
42
that lessens the extraneous burden of fighting to try to learn the language,
43
deliberately try to learn the language from content that's of no interest or a voice that I don't like or a screechy, scratchy audio recording.
44
In other words, everything that makes the task more enjoyable reduces the extraneous cognitive burden.
45
Now, along the same lines we all have different tastes in
46
what we like to do i'm not a fan of uh
47
sort of deliberate retrieval exercises drills flashcards you name it that's not to say
48
that people who like doing those things aren't going to benefit
49
from them it's a matter of what people enjoy doing
50
if you enjoy doing it then the extraneous sort of cognitive burden is is lessened
51
so in my own case i like listening and reading
52
and there is ample evidence that reading is in fact a form of retrieval exercise. In fact, it is retrieving words and phrases
53
or in the case of listening sounds from a meaningful context which according to some research is more effective than
54
trying to retrieve things in isolation.
55
So where I'm coming from in this discussion of cognitive load is
56
that it still comes down to the basic issue of trying to keep things simple and enjoyable.
57
How do we encourage the learner to stay on task?
58
How do we increase the likelihood that the learner will enjoy the process, the learning process?
59
And in that sense, the emphasis should be the perspective of the learner rather than how teachers
60
or educators can structure activities in the classroom or design textbooks or things of that nature, which introduce a level of complexity,
61
which may, in fact, not contribute to lessening the cognitive load.
62
Cognitive load will be lessened if the task is simpler, more straightforward, and more enjoyable.
63
So as a layman, That's my reaction to this whole issue of the cognitive burden.
64
Thank you for listening.

为什么学英语总觉得累?可能是认知负荷在作怪
很多人学英语时总抱怨“记不住”“学不进去”,其实未必是不够努力,而是没搞清“认知负荷”这个关键。视频里提到,学习任务的难易程度会直接影响记忆和吸收效率,而降低认知负荷的核心,就是让任务更简单、更有趣。这对英语口语练习尤其重要——毕竟,谁也不想对着枯燥的材料硬啃。
提升影子跟读效率的3个小技巧
影子跟读(shadowspeak)是练口语的好方法,但很多人练得痛苦又没效果。试试视频里的思路,或许能帮你减负:
- 激活已有知识:先听一遍材料,抓住自己熟悉的单词或短语,再开始跟读。就像除草前先把刀片调高,第一次先“轻松过一遍”,第二次再深入,负担会小很多。
- 选感兴趣的内容:如果材料是你喜欢的话题,哪怕难度稍高,也更容易坚持。毕竟,没人会拒绝边追喜欢的内容边学英语,这就是看视频学英语的优势。
- 避免机械重复:别死磕 flashcards 或 drills,试试在听读中自然回忆。比如读一段文章时,有意识地回想学过的表达,比孤立记忆更有效,还能降低认知负担。
其实,英语影子跟读的关键不是“快”或“准”,而是让自己在舒适的状态下持续输入。就像滑雪时沿着前人的轨迹,虽然可能会有新雪覆盖,但滑行会更轻松。降低认知负荷,才能让英语学习变成一件可持续的事。
视频中的语法
说话人最常用的结构,并附上视频中的原话:
| 结构 | 视频中的用法 |
|---|---|
| 现在完成时 have/has + 过去分词 — 过去发生但与现在仍有关联的事 | I've talked · I've often said · have walked |
| 被动语态 be + 过去分词 — 强调发生了什么,而不是谁做的 | been made · is lessened · will be lessened |
什么是跟读法?
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧,最初开发用于专业口译员的培训,并由多语言者Alexander Arguelles博士普及。这个方法简单而强大:您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同,跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性,语调,节奏,连读,听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
