Why do we remember certain moments vividly while others disappear instantly? Why does a childhood scent trigger a flood of memories, but a colleague’s name stays on the tip of the tongue? Human memory is a complex system, blending biology, emotion, and cognition.

In How Does Human Memory Work? by Léwis Verdun, the Five Minutes collection delivers a clear and rapid guide to the brain’s mechanisms. This article explores a related topic: how can we improve our memory by understanding how it works?

The Key Stages of Memory: From Encoding to Retrieval

Memory works in several phases:

Encoding
This is when information enters the brain. For encoding to succeed, attention is essential. The brain filters data based on novelty, repetition, and emotional significance.

Storage
Memories are stored in various brain areas. The hippocampus is central to long-term memory, while the amygdala intensifies emotional memories.

Consolidation
Memories move from short-term to long-term storage, often during sleep.

Retrieval
Recalling a memory reactivates it. However, each recall can alter the memory slightly—a process called "reconsolidation."

Why Do We Forget? Active Forgetting and the Google Effect

Forgetting isn’t a flaw—it’s crucial for avoiding cognitive overload. We forget to make room for relevant information.

Digital technology has changed how we remember. The Google Effect describes the tendency to forget facts easily accessible online. This affects memory but also teaches us to focus on finding information rather than storing it.

Emotions: Memory Accelerators

Emotional experiences embed more deeply into memory. The amygdala intensifies storage when emotions are involved.

That’s why you may clearly remember your first love or a traumatic event, but forget where you parked your car last week.

Practical Strategies to Boost Memory

Understanding how memory works allows you to use effective techniques to enhance learning:

Spaced repetition
Review information at increasing intervals rather than cramming.

Mnemonic devices
Acronyms, visualization, and associations help store information long-term.

Healthy lifestyle
Sleep, exercise, and nutrition are crucial for memory performance.

Focus and attention
Learning without distractions improves encoding and recall.

Balancing Biological Memory and Digital Tools

Technology can help or hinder memory. To use it wisely:

  • Use flashcards or spaced repetition apps.

  • Write by hand to engage deeper cognitive processes.

  • Practice mindfulness to train attention.
