As part of our study of the brain's various functions, we're going to look at the topic of memory.

This is a fascinating topic, really.

Now, who remembers what they ate for lunch last Monday?

I remember having pizza.

That's memory at work.

A simple definition of memory is the ability to store, retain, and recall the information.

It sounds simple, but if you think about it, in many ways we are our memories.

When we think about who we are, we probably think about the events we've experienced, the people we've known, as well as the opinions and the feelings we have about a great many things.

All of this information is stored in a variety of brain systems that handle the different types of memory.

So first, let's look at three types of memory that have been identified by psychologists, Then I'll talk about how we can improve our memories.

The first type of memory is sensory memory.

Sensory memory is extremely short.

It generally lasts about 100 to 500 milliseconds.

As the name suggests, sensory memory concerns the initial moment that we perceive something with our senses.

For instance, consider tactile sensory memory.

If you touch a piece of silk, the memory of the smoothness of the silk will continue after you take your hand away.

That's sensory memory at work.

Now it's important for learning and remembering because using more senses means we've recorded the experience in more ways in our brain.

The next type of memory is working memory, which is extremely important in everyday life.

Working memory is a system where we temporarily hold and manipulate information.

You think of it as a temporary workspace in your mind.

For instance, if your friend tells you a phone number and you don't have a pen, you probably repeat the number several times in your mind so that you remember it.

In that case, you're using working memory.

Now it's absolutely crucial for performing common mental operations like adding numbers,

following directions, and understanding logical relationships between ideas.

Finally there's what's called long-term memory,

which is memory that's stored for as little as 30 seconds to as long as your entire lifetime.

Now psychologists believe that most long-term memories are information and experiences that were initially processed in working memory,

in meaningful and perhaps in emotional ways.

For instance, I clearly remember the first time I saw the Grand Canyon.

I was only 15 years old,

but the size just amazed and impressed me so much that even decades later it's still very clear in my mind.

Now there are two subtypes of long-term memory.

There's declarative memory and procedural memory.

Declarative memory is all of the facts and ideas and names that are consciously available to you.

All of your experiences and conscious memories fall into this category.

Procedural memory concerns your knowledge of moving your body.

Like when you ride a bicycle or you play a musical instrument.

Most of our procedural memories are implicit and unconscious.

Okay, now I'm going to test your memory memory with this question.

Does anyone remember what I said I'd talk about next?

How to improve your memory, right?

When we think about improving our memory, we're generally talking about improving our declarative memory, the one that stores the facts and the names and so on.

This type of memory can be improved if we use certain strategies.

So I want to talk about two types of memory strategies that are useful in school.

Cognitive strategies and affective strategies.

Now, cognitive strategies tell us how to approach tasks and which methods to use to complete them.

So basically, they're concerned with thinking in more effective ways.

Okay, let's take a quick look at one cognitive strategy, this one's called verbal elaboration.

A verbal elaboration occurs when we talk in a meaningful way about information that we are trying to remember.

And that means that as you study, you should think about and verbalize information critically.

You can use this strategy by agreeing or disagreeing with the information, or by comparing and contrasting the information to ideas you already know,

or by discussing relationships between ideas.

When we make meaningful relationships between what we already know and what we're trying to learn, we'll remember more and we'll remember it longer.

Now, for the other approach, affective strategies.

Affective strategies help us control our emotional responses so that we remember better.

What do emotions have to do with memories?

Well, emotions cause the release of brain chemicals that play a direct role in memory formation.

And part of the emotion system in the brain, called the limbic system, helps transfer information into long-term memory.

In other words, how you feel about something affects how well you remember it.

So, what affective strategies can you use to create positive emotional responses while studying?

First, study with one or two friends from class.

This can make any study session more interesting, more enjoyable.

Second, use interesting study tasks like taking turns, making short presentations on a topic that you're studying.

Or come up with questions to test each other on the information.

See, the point of trying the affective strategy is that it will increase not only your memory, but also your sense of fun and challenge and interest.

And you can do this for any subject.

Now, are there any questions?

本片段的口语练习目标

本视频有助于提升英语学习者在说明性话题表达中的流畅度，尤其是如何清晰阐述概念、分类及举例。通过模仿视频中对“记忆类型”和“记忆策略”的讲解结构，学习者能掌握逻辑分层表达的技巧，提升在学术或日常讨论中“有条理输出信息”的能力，为影子跟读（shadowspeak）练习提供实用素材。

实用短语库

“As the name suggests”——顾名思义
“For instance”——例如
“It's important for... because...”——这对……很重要，因为……
“You think of it as...”——你可以把它看作……
“Now, let's take a quick look at...”——现在，让我们快速了解一下……
“This type of... can be improved if we use...”——如果我们使用……，这类……可以得到提升

攻克口语弱点

视频中的讲解语速适中，句子结构清晰，非常适合用于英语影子跟读（shadow speak）练习。学习者可重点关注以下两点：
1. 长句断句节奏：模仿主讲人在阐述“工作记忆”“长时记忆”等概念时的停顿，如“Working memory is a system / where we temporarily hold and manipulate information”，通过影子跟读（shadowing）训练，提升口语中的自然断句能力。
2. 学术词汇发音：例如“sensory memory”（感觉记忆）、“declarative memory”（陈述性记忆）等术语的重音位置，可结合影子跟读网站（shadowing site）反复练习，确保发音准确。
建议每天抽取5分钟，使用视频进行影子跟读练习，坚持一周即可明显提升口语流畅度。

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	we've experienced · have been identified · we've recorded
被动语态 be + 过去分词 — 强调发生了什么，而不是谁做的	is stored · have been identified · can be improved

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。
