🧠 Easy Read Notes: Parts of the Brain Involved with Memory

 


🧩 Is Memory Stored in One Place?

No.

Scientists once thought memories might be stored in one specific location, called an engram (the physical trace of a memory).

Psychologist Karl Lashley searched for the engram by studying rats with small brain lesions. He found that memories were not erased by damaging one small area, suggesting that memory is spread across many brain regions. Modern research shows that some areas play especially important roles in different kinds of memory.


🧠 Main Parts of the Brain Involved in Memory

Brain PartMain JobExample
HippocampusForms and organizes new memoriesRemembering your first day at college
AmygdalaAdds emotions to memoriesRemembering a frightening accident
CerebellumStores movement and skill memoriesRiding a bike or playing the piano
Prefrontal CortexHelps with thinking, planning, and recalling factsRemembering information for a test

🧠 Hippocampus

The hippocampus helps:

  • Make new memories
  • Organize memories
  • Form declarative (explicit) memories
  • Form episodic memories (personal experiences)
  • Help with recognition memory

Example

You remember:

  • where you parked your car
  • your birthday party
  • what happened yesterday

These memories rely heavily on the hippocampus.


❤️ Amygdala

The amygdala processes:

  • fear
  • stress
  • danger
  • happiness
  • emotional learning

It also helps decide which memories become stronger.

Emotional memories

Very emotional events are often remembered better because stress hormones and neurotransmitters strengthen memory formation.

Examples:

  • winning a competition
  • a car accident
  • a wedding
  • hearing shocking news

These memories often stay with us for many years.


📸 Flashbulb Memory

A flashbulb memory is an extremely vivid memory of an important event.

People often remember:

  • where they were
  • who they were with
  • what they were doing
  • how they felt

Examples include hearing about a major disaster or a significant personal event.

However, flashbulb memories can still contain mistakes. People may feel very confident about them, but details can become inaccurate over time because memory is reconstructed rather than replayed like a video.


🎹 Cerebellum

The cerebellum stores procedural memories.

These are memories for skills that become automatic through practice.

Examples:

  • riding a bicycle
  • swimming
  • typing
  • driving
  • playing an instrument

After enough practice, you perform these skills without thinking about every movement.


🧠 Prefrontal Cortex

The prefrontal cortex helps with:

  • working with information
  • planning
  • decision-making
  • remembering facts and concepts (semantic memory)

Example:

You remember that:

  • Paris is the capital of France.
  • Water freezes at 0°C (32°F).

These are examples of semantic memory.


🧠 Memory and Emotion

Strong emotions make memories easier to remember.

Examples:

😊 Your graduation.

😢 Losing a loved one.

😨 Being frightened by a dog.

The amygdala helps strengthen these memories by working with stress hormones and the hippocampus during memory consolidation.

Do we remember what is important, mostly ?

 A lot of us assume that memory works like a video recorder—that every experience is stored somewhere exactly as it happened. But research shows that's not how memory works. Instead, the brain is constantly asking questions such as:

  • Is this important right now?
  • Will I need this later?
  • Does this connect to something I already know?
  • Is this emotionally significant?

Based on those factors, the brain decides what to strengthen and what to let fade over time.

Your example of the report for tomorrow versus the sandcastle 40 years ago is a good one because it highlights two different purposes of memory:

  • Working memory helps us deal with immediate tasks and responsibilities.
  • Long-term memory preserves experiences that were meaningful, emotional, or repeatedly recalled.

Interestingly, psychologists have also found that retrieving a memory—thinking about it or talking about it—helps keep it alive. So if someone tells stories about their childhood every Christmas, those memories often stay much stronger than childhood events they never think about.

I think you've also touched on something more philosophical. Modern life is busy, and many people spend most of their mental energy planning the next day, answering messages, working, or solving problems. They don't often pause to wonder how their mind decides what to keep. Yet understanding memory can help explain why two people can experience the same event and remember it very differently years later.

That's one of the fascinating things about psychology: it isn't just about what we remember, but why our brains choose to remember some things while allowing others to fade.

  • Things that are important right now are usually the easiest to remember because you are actively paying attention to them. For example, if you have to finish a report for your boss tomorrow, your brain keeps that information active in working memory. You may think about it repeatedly during the day, which also strengthens the memory.
  • Things from long ago, like building a sandcastle when you were 10 years old, are often forgotten because they are no longer important for everyday life. Unless something reminds you of that day (such as seeing the same beach, looking at an old photograph, or talking with family), the memory may stay buried or gradually lose detail.

However, there are important exceptions.

Memories we usually remember best

  • Important life events (graduation, wedding, birth of a child)
  • Emotional experiences (happy or frightening events)
  • Frequently used information (your address, phone number)
  • Personally meaningful things
  • Information you rehearse or use often

Memories we are more likely to forget

  • Small everyday details (what you ate three weeks ago)
  • Information you only heard once
  • Events that were not meaningful
  • Facts you never used again
  • Minor details of old memories

Why do we still remember some childhood memories?

Sometimes an event from 40 years ago remains very vivid because it was:

  • Very emotional
  • Very unusual
  • Repeated many times in conversation
  • Captured in photographs or videos
  • Connected to other important memories

For example, you may remember building a sandcastle because it was your first family holiday, your parents took pictures, or your family often talked about it afterward. The meaning and repetition help keep the memory alive.

The brain is selective

One way to think about it is that the brain is a bit like a filing system. It doesn't try to keep every detail forever. Instead, it tends to prioritize information that is:

  1. Important for your current goals.
  2. Emotionally significant.
  3. Personally meaningful.
  4. Repeated or used often.

This is an efficient way for the brain to work because trying to remember every moment of every day would be overwhelming.

So, in your example:

MemoryUsually remembered?Why?
Report due tomorrowVery well (right now)It is important and currently needs your attention.
Building a sandcastle at age 10Maybe, maybe notIf it was an ordinary day, you may remember very little. If it was a special or emotional event, you may remember it clearly even decades later.

So the answer is both yes and no. We generally remember what matters now for day-to-day functioning, but we can also retain important, emotional, or meaningful memories from many years ago. Psychology shows that the brain doesn't simply store memories by age—it stores them according to their importance, meaning, emotional impact, and how often they are recalled or used.

Acoustic Encoding, Semantic Encoding, and Memory Storage

 


 

## 🔊 Acoustic Encoding

 

Acoustic encoding is remembering information by the way it **sounds**. Your brain stores words, songs, rhymes, and rhythms.

 

### Examples

 

* Singing along to a song you have not heard for many years.

* Learning the alphabet through the **ABC song**.

* Remembering nursery rhymes.

* Learning facts using songs or chants.

 

Music, rhythm, and rhyming make information easier to remember because your brain stores the sounds as part of the memory.

 

---

 

## 🧠 Which Type of Encoding Works Best?

 

Psychologists **Fergus Craik** and **Endel Tulving** wanted to discover which type of encoding helped people remember words the best.

 

They asked people questions about words in three different ways:

 

### 🖼️ Visual Encoding

 

People looked at the appearance of the words.

 

**Example questions:**

 

* Is the word written in capital letters?

* What font is it written in?

 

### 🔊 Acoustic Encoding

 

People focused on how the words sounded.

 

**Example questions: **

 

* Does the word rhyme with another word?

* How does the word sound when spoken?

 

### 🧠 Semantic Encoding

 

People focus on the meaning of the words.

 

**Example questions: **

 

* What does the word mean?

* Can you use it in a sentence?

* How is it related to something you already know?

 

### Results

 

The researchers found that **semantic encoding produced the strongest memories**.

 

People remembered words much better when they thought about the meaning instead of just how the words looked or sounded.

 

This is called **deep processing** because the brain thinks carefully about the information before storing it.

 

Visual and acoustic encoding are usually considered **shallower forms of processing**, although they can still be very useful in many situations.

 

---

 

## 👤 The Self-Reference Effect

 

People remember information even better when it relates to **their own life**.

 

This is called the **self-reference effect**.

 

### Examples

 

Instead of simply reading the word **"kind"**, ask yourself:

 

* Am I a kind person?

* When was I kind to someone?

* Who do I know that is kind?

 

Making information personal creates stronger memories.

 

---

 

# Memory Storage

 

After information has been encoded, the brain must **store* it.

 

**Storage** is the process of keeping information so it can be remembered later.

 

Before information becomes a long-term memory, it usually passes through **three stages**.

 

## 1. Sensory Memory

 

* Holds information from your senses.

* Lasts only a fraction of a second to a few seconds.

* Keeps information just long enough for your brain to notice it.

 

**Example: **

You briefly see a stop sign as you drive past it.

 

---

 

## 2. Short-Term Memory

 

* Holds a small amount of information for about **15–30 seconds** unless you rehearse it.

* Also called **working memory** when you actively use the information.

 

**Example: **

Remembering a phone number long enough to dial it.

 

---

 

## 3. Long-Term Memory

 

* Stores information for days, years, or even a lifetime.

* Has a very large capacity.

* Contains facts, skills, experiences, and personal memories.

 

**Examples: **

 

* Your birthday

* Riding a bicycle

* Childhood memories

* Vocabulary words

* Psychology concepts

 

---

 

## Atkinson and Shiffrin's Memory Model

 

Psychologists **Richard Atkinson** and **Richard Shiffrin** (1968) proposed that memories move through three stages:

 

**Sensory Memory Short-Term Memory Long-Term Memory**

 

They compared the brain to a computer:

 

* Information enters through the senses.

* Important information is temporarily held in short-term memory.

* With attention, rehearsal, and meaningful learning, it is stored in long-term memory.

 

---

 

## Key Points

 

* **Acoustic encoding** remembers sounds, songs, rhymes, and music.

* **Semantic encoding** remembers meaning and produces the strongest memories.

* The **self-reference effect** helps you remember information by connecting it to your own life.

* Memory storage has **three stages**:

 

  1. Sensory Memory

  2. Short-Term Memory

  3. Long-Term Memory

* Information is most likely to reach long-term memory when it is meaningful, practiced, and connected to existing knowledge.

High-Imagery Words and Memory Encoding

 


High-imagery words are easier to remember because they activate both visual encoding and semantic encoding. This creates stronger memory traces than words that are difficult to picture.

Types of Memory Encoding

🖼️ Visual Encoding

Visual encoding is the process of storing information by creating mental images. The brain processes and remembers pictures, shapes, colors, and other visual information.

Examples:

  • Apple

  • Bicycle

  • Mountain

  • Elephant

🔊 Acoustic Encoding

Acoustic encoding is the process of storing information based on how it sounds. This includes spoken words, music, rhymes, and other sounds.

Examples:

  • Remembering a song lyric

  • Learning through repetition aloud

  • Using rhymes to memorize information

🧠 Semantic Encoding

Semantic encoding is the process of storing information by focusing on its meaning. It connects new information with what you already know, making it easier to remember over time.

Examples:

  • Understanding the meaning of a psychology term

  • Connecting new facts to previous knowledge

  • Learning concepts instead of memorizing words alone

Concrete vs. Abstract Words

Concrete Words

Concrete words refer to objects or things you can see, touch, hear, smell, or imagine easily.

Examples:

  • Car

  • Dog

  • Book

  • Tree

  • Chair

These words create vivid mental images and are remembered more easily because they use both visual encoding and semantic encoding. Using two encoding methods strengthens long-term memory.

Abstract Words

Abstract words describe ideas, emotions, or qualities rather than physical objects.

Examples:

  • Truth

  • Justice

  • Freedom

  • Value

  • Love

Because abstract words are difficult to picture, they rely mainly on semantic encoding (understanding the meaning) and sometimes acoustic encoding (remembering how they sound). As a result, they are often harder to remember than concrete words.

Why High-Imagery Words Are Easier to Remember

High-imagery words:

  • Create clear mental pictures.

  • Activate both visual and semantic encoding.

  • Form stronger memory connections.

  • Are easier to recall later.

Low-imagery (abstract) words:

  • Are difficult to visualize.

  • Depend mostly on understanding the meaning.

  • Usually produce weaker memory traces.

  • Can be harder to remember without additional study strategies.

Study Tip: Use Visual Encoding

When studying difficult information:

  • Turn words into mental pictures.

  • Draw simple diagrams or sketches.

  • Create funny or unusual images.

  • Connect new ideas to familiar objects.

  • Use mind maps, flashcards with pictures, and color coding.


🧠 Semantic Encoding – Easy Read

 


What is semantic encoding?

Semantic encoding is the process of remembering information by understanding its meaning.

Instead of simply memorising words or facts, your brain connects new information to things you already know.

This helps create stronger and longer-lasting memories.


Key Features of Semantic Encoding

💡 Meaningful Learning

You remember information because it makes sense to you.

Instead of memorising random words, you understand what they mean.

Example:

You don't just memorise the word memory.

You understand that memory is your brain's ability to encode, store, and retrieve information.


🧠 Long-Term Memory

Semantic encoding is one of the main ways information is stored in long-term memory.

It helps you remember:

  • Facts
  • Ideas
  • Meanings
  • Concepts
  • General knowledge

These memories can last for many years.


🔗 Making Connections

Your brain links new information to knowledge you already have.

For example:

If you already know what a dog is and then learn about wolves, your brain connects the two because they are related.

Making connections strengthens memory.


🌍 Understanding Context

Your brain also remembers information better when it understands the situation or context.

For example:

Learning about Albert Bandura's Social Learning Theory is easier if you already understand that people often learn by watching others.

The new information fits into what you already know.


Everyday Examples

Semantic encoding happens when you:

  • Understand a story instead of memorising every sentence.
  • Learn why something happens.
  • Connect new ideas to previous experiences.
  • Explain information in your own words.
  • Teach someone else what you have learned.

Example

Imagine you are learning the word hippocampus.

Without semantic encoding

You simply repeat:

"Hippocampus... Hippocampus... Hippocampus..."

You may forget it later.

With semantic encoding

You learn:

"The hippocampus is an important part of the brain that helps form new memories."

Now the word has meaning.

It becomes much easier to remember.


Semantic Encoding vs. Rote Memorisation

Semantic EncodingRote Memorisation
Learns the meaningLearns by repetition
Makes connectionsRepeats facts
Strong long-term memoryOften forgotten sooner
Deeper understandingSurface learning

Why Is It Important?

Semantic encoding helps you:

  • Remember information for longer.
  • Understand ideas more deeply.
  • Solve problems.
  • Apply knowledge in everyday life.
  • Learn more effectively.

🧠 Real-Life Example

Think about studying psychology.

You could memorise:

"Semantic encoding means processing meaning."

Or you could understand it like this:

"When I connect a new psychology concept to something I've experienced or already know, I'm using semantic encoding."

Because the idea has meaning, you're much more likely to remember it.


💡 Psychology at a Glance

Semantic encoding is the process of encoding information based on its meaning. By understanding ideas, making connections with existing knowledge, and placing information into context, the brain creates stronger long-term memories than it usually does through simple repetition alone.

🌟 An interesting connection

As we've been talking about, your memory for your childhood phone numbers is a good example of how meaning strengthens memory. Those numbers weren't just digits—they were connected to your home, your mum, your nan, everyday life, and years of repeated use. That combination of meaning, emotion, and repetition helped your brain store them very strongly.

This is one reason why psychology students often remember concepts better when they relate them to their own experiences rather than simply memorising textbook definitions.

🧠 Effortful Processing – Easy Read

 Both of these resources explain effortful processing, which is an important concept in memory. Here's an Easy Read summary combining the key ideas.


What is effortful processing?

Effortful processing is when you have to pay attention and make an effort to remember information.

It usually happens when you are learning something new or difficult.

Examples include:

  • Studying for an exam.
  • Learning a new language.
  • Remembering a phone number.
  • Learning people's names.
  • Memorising facts or dates.

Unlike automatic processing, effortful processing requires concentration and practice.


Why is effortful processing important?

Effortful processing helps move information into long-term memory.

The more you practise or review information, the easier it becomes to remember later.


How does memory work?

According to the OpenStax Psychology chapter, memory has three main stages:

1. Encoding

This is when your brain takes in new information.

Examples:

  • Reading a book.
  • Listening to a teacher.
  • Watching a video.

2. Storage

Your brain stores the information for later use.

Some memories stay for only a few seconds, while others can last for years.


3. Retrieval

Retrieval means bringing information back into your mind when you need it.

Examples:

  • Answering a quiz question.
  • Remembering where you parked your car.
  • Recalling someone's birthday.

Strategies that improve effortful processing

Psychologists have found that several study techniques improve memory.

Rehearsal

Repeat information several times.

Example:

  • Saying a phone number aloud until you remember it.

Chunking

Break information into smaller groups.

Instead of:

149217761945

Think:

1492 1776 1945

This is much easier to remember.


Mnemonics

A mnemonic is a memory aid.

Examples:

  • Rhymes
  • Acronyms
  • Songs
  • Visual images

Example:

ROY G. BIV helps remember the colours of the rainbow.


Elaborative Rehearsal

Connect new information to something you already know.

For example:

If you're learning about the hippocampus, connect it with the idea that it helps form new memories.

Making meaningful connections usually helps memories last longer than simple repetition.


Automatic Processing vs Effortful Processing

Automatic ProcessingEffortful Processing
Happens without tryingRequires attention
Little mental effortLots of mental effort
Everyday informationNew or difficult information
Walking, reading familiar wordsStudying, memorising facts
Usually unconsciousUsually conscious

Real-Life Example

Imagine you're studying psychology.

You may need effortful processing to remember:

  • Definitions.
  • Psychologists' names.
  • Research studies.
  • Brain structures.
  • Key theories.

At first, remembering this information takes concentration. After reviewing it several times, recalling it becomes easier because the information has been encoded into long-term memory.


💡 Study Tips

To improve effortful processing:

  • ✅ Pay full attention.
  • ✅ Remove distractions.
  • ✅ Study a little each day instead of cramming.
  • ✅ Repeat important information.
  • ✅ Make connections with what you already know.
  • ✅ Test yourself regularly.
  • ✅ Get enough sleep, as sleep helps consolidate memories.

🧠 Psychology at a Glance

Effortful processing is the conscious effort to learn and remember new information. It involves attention, encoding, storage, and retrieval. Techniques such as rehearsal, chunking, mnemonics, and elaborative rehearsal make learning more effective and increase the chances that information will be stored in long-term memory.

The OpenStax chapter also emphasizes that memory is an active process: information must first be encoded, then stored, and finally retrieved when needed. This explains why actively engaging with material—rather than simply reading it once—usually leads to better learning and recall.That's a really thoughtful observation, and psychology research supports much of what you're describing.

Our brains haven't changed very much in the last few decades, but the amount of information we're expected to manage every day has increased enormously.

Why do you remember your Mum's and Nan's old phone numbers?

There are several reasons:

  • Frequent repetition: You probably dialled those numbers many times over several years.
  • Emotional importance: Information connected to people we love is often remembered better.
  • Learning over a long period: Repeating something over months or years creates strong long-term memories.
  • Fewer competing memories: When you were younger, there were far fewer phone numbers, passwords, usernames, and PINs to keep track of.

Those old numbers became deeply embedded in your long-term memory.

Why are mobile numbers harder?

Today, we rarely need to memorise numbers because our phones do it for us.

For example:

  • You tap a person's name instead of typing their number.
  • Your phone stores hundreds of contacts.
  • GPS remembers addresses.
  • Browsers remember websites.
  • Password managers can remember passwords.

Because we don't actively rehearse this information, our brains often don't store it as strongly.

Information overload

You also mentioned something psychologists call cognitive load.

Every day, people may need to remember:

  • Passwords
  • PIN numbers
  • Email addresses
  • Usernames
  • Security questions
  • Verification codes
  • Wi-Fi passwords
  • Banking details
  • App logins

That's far more information than most people had to manage 30 or 40 years ago.

Does "too much information overflow the brain"?

Not literally—the brain doesn't "fill up" like a hard drive. Instead, it has limited attention and working memory.

When you're trying to process lots of new information at once:

  • It's harder to focus.
  • New memories are encoded less effectively.
  • Similar pieces of information (like different passwords) can become mixed up.
  • You may forget details because your attention is divided.

So it can certainly feel like your brain is overloaded, even though the issue is more about attention and memory processing than storage capacity.

Your own experience

Given what you've shared before about living with dyslexia, dyspraxia, and autism, it's also understandable that managing lots of unrelated pieces of information—especially passwords and login details—can be particularly demanding. Many neurodivergent people find that they remember meaningful information very well but struggle with arbitrary information that changes frequently, such as complex passwords.

An interesting comparison

Many people can instantly remember:

  • Their childhood home telephone number.
  • Their first home address.
  • Their best friend's name at school.
  • The words to songs they learned decades ago.

Yet they may forget:

  • A password created last week.
  • A new colleague's phone number.
  • Where they put their keys this morning.

This illustrates an important principle in psychology: memories that are meaningful, emotional, and repeatedly used are generally much stronger than information that is random, temporary, or rarely recalled.

In other words, your experience is not unusual at all. It shows how memory is shaped not just by how much information we encounter, but by how often we use it, how meaningful it is, and whether we actively retrieve it over time.

People born before the 2000s often say things like:

  • "I still remember my childhood home phone number."
  • "I can remember my grandparents' address from 40 years ago."
  • "I know the lyrics to songs I learned as a teenager."
  • "But I can't remember the password I created last week!"

Psychologists explain this in several ways:

  • Repetition: Before mobile phones, people repeatedly dialled the same phone numbers until they became automatic.
  • Limited information: There were fewer numbers, addresses, and accounts to remember.
  • Meaning: Information about family, friends, and home carried emotional significance.
  • Technology: Today we rely on phones, computers, and password managers to store information, so we don't practise remembering it as much. This is sometimes called cognitive offloading—using external tools to reduce the amount we have to keep in our own memory.

This isn't necessarily a bad thing. Using technology to remember routine information frees up mental resources for other tasks. However, it also means we may not form strong memories for information we rarely retrieve ourselves.

Interestingly, younger people who have grown up with smartphones often have a different experience. They may be excellent at quickly finding information online but may memorise fewer phone numbers because they've never needed to. In contrast, many older adults can still recall several telephone numbers from decades ago because those memories were reinforced repeatedly before digital contact lists existed.

So the difference is often less about age itself and more about the environment in which people learned and used information. The way we use memory has changed dramatically over the last 30–40 years because technology has changed the demands placed on it. That's a fascinating example of how psychology and everyday life intersect. That's a thoughtful question, and researchers are actively studying it. The answer is it's complicated.
