Declarative And Procedural Memory Are Two Types Of What? | Now

They’re two types of long-term memory: one stores facts and events you can name, the other stores skills your body can run on autopilot.

If you’ve recalled a friend’s birthday, you leaned on declarative memory. If you’ve typed a familiar password without staring at the keys, you leaned on procedural memory. Those two moments feel different because the brain handles them with different long-term memory systems.

What Long-Term Memory Means In Daily Life

Long-term memory is storage that can last from hours to decades. It isn’t one single “folder.” It’s a set of storage methods built for different jobs. One method is tuned for information you can put into words. Another is tuned for routines you can perform smoothly.

A fast self-check works well here. If you can state the information as a fact or a story, you’re in the declarative lane. If you can do the action well while your attention is elsewhere, you’re in the procedural lane.

Declarative And Procedural Memory Types In Long-Term Memory Basics

Declarative memory (often called explicit memory) stores information you can consciously bring to mind and state. Procedural memory stores learned skills and habits that show up through action, often with little conscious effort.

This two-part split shows up in many clinical and neuroscience references. A StatPearls overview hosted in the National Library of Medicine’s Bookshelf describes long-term memory as dividing into declarative and procedural categories. NCBI Bookshelf overview of long-term memory types uses the same framing you’ll see in many textbooks.

What Fits Under Declarative Memory

Declarative memory is usually described in two subtypes:

• Episodic memory: Events tied to a place and time.
• Semantic memory: Facts and meanings.

When you study a chapter, memorize a date, or recall what you did last weekend, you’re working in this system. You can test it with recall and recognition tasks: retelling a story, listing items, naming objects, or choosing the correct answer from options.

What Fits Under Procedural Memory

Procedural memory is the “how-to” side of long-term memory. It’s behind routines that improve through repetition, like tying shoes, shifting gears on a bike, playing a familiar chord, or touch-typing common letter patterns.

When a skill becomes procedural, it can feel automatic. You can still pay attention to it, yet you don’t have to narrate each micro-step for it to run.

Why The Labels Matter

The two systems can separate in real life. Some people struggle to form new memories they can talk about and still keep long-practiced skills. Other people have the opposite pattern when movement-related learning is disrupted. That separation is one reason clinicians and researchers keep using these categories.

Declarative And Procedural Memory Are Two Types Of What?

They’re two types of long-term memory. Declarative memory holds facts and events you can consciously recall. Procedural memory holds skills and habits you show through action. Cleveland Clinic’s explainer describes declarative (explicit) and nondeclarative (implicit) long-term memory types. Cleveland Clinic’s long-term memory types page is an easy reference point.

If you want a textbook-style definition, Britannica’s long-term memory entry describes declarative memory for facts and events and nondeclarative (procedural) memory for skills and routines.

How The Brain Tends To Support Each Type

Memories aren’t stored in one single spot. Different networks do different jobs. A common summary looks like this: declarative memory relies heavily on the hippocampus and nearby medial temporal lobe structures, especially during early learning. Procedural memory relies more on circuits that tune repeated action and habits, including basal ganglia networks. Stanford Medicine’s summary chapter on basal ganglia-related memory disorders notes a common split: nondeclarative memory depends a lot on basal ganglia circuits, while declarative memory relies more on the hippocampus and medial temporal lobe structures. Stanford Medicine summary on basal ganglia and memory systems lays out that division in plain terms.

These systems communicate. Real learning often uses both. When you learn a new recipe, you may memorize the steps (declarative), then develop timing and hand-feel through repetition (procedural).

Declarative Memory Often Feels Like “Pulling It Up”

When you try to remember a name or a detail from a story, you may feel a brief search, then the answer clicks. Declarative learning tends to benefit from attention during the first exposure, then repeated recall later.

Procedural Memory Often Feels Like “Just Doing It”

With practice, skills shift from effortful to smooth. The early phase can feel clumsy. The later phase is more stable, faster, and easier to run while your mind is busy with something else.

Fast Ways To Spot Which Type You’re Using

• Say it test: If you can state it as a fact or describe the event, that’s declarative memory.
• Do it test: If you can perform it smoothly, that’s procedural memory.
• Teach it test: If you can do it but can’t explain every step, procedural memory can still be strong.

Over-explaining a well-learned skill can even make you worse at it. That’s because you pull attention back into conscious control instead of letting the routine run.

Mistakes That Make Learning Feel Harder Than It Is

Treating A Skill Like A Reading Assignment

Reading about a skill can make you feel ready. Performance often says otherwise. Skills need repetitions that match the real action, plus feedback that keeps form honest.

Treating Facts Like A Drill-Only Routine

Repeating a fact without meaning can create a fragile memory. Facts stick better when you connect them to what you already know, then practice pulling them back from memory after a short gap.

Using Practice That Never Gets Checked

If you repeat mistakes, you teach your brain the mistakes. Feedback can come from a coach, a timer, a metronome, a checklist, or a quick video clip. The tool matters less than the honest signal: “That rep was clean” or “That rep drifted.”

Comparison Table: Declarative Vs Procedural Memory

Aspect	Declarative Memory	Procedural Memory
What it stores	Facts and events you can state	Skills, habits, routines shown through action
Access style	Conscious recall is common	Often runs with little conscious effort
Typical subtypes	Episodic and semantic	Skill learning and habits
Learning driver	Meaning, attention, repeated recall	Repetition, feedback, gradual refinement
Practice that helps	Self-testing, explaining, spaced review	Clean reps, chunk drills, speed ramps
Everyday sign	You can tell someone what happened	You can do it while chatting
Brain network often linked	Hippocampus and medial temporal lobe networks	Basal ganglia-linked habit/skill circuits
What failure looks like	“I learned it, but it won’t come back”	“I get it, but I can’t execute it”

Study Moves That Build Declarative Memory

Use Active Recall In Short Sets

Read a small section, close it, and write what you remember. Then check and correct. This trains retrieval, not just exposure.

Space Your Repeats

Spacing means you revisit the same material after a gap. A gap makes recall harder, and that effort strengthens the memory. A basic schedule can be: same day, two days later, one week later, then two weeks later.

Link New Facts To Familiar Hooks

If you connect a new fact to something you already know, you add extra paths back to it later. A hook can be a prior lesson, a real-life scene, or a simple association that feels sticky.

Match Your Practice To Your Test

If you need to answer in writing, practice writing. If you need to speak, practice saying the answer out loud. Cue-matching makes retrieval smoother when it counts.

Practice Moves That Build Procedural Memory

Start Slow Enough To Stay Clean

Slow reps teach your brain the version you want. Sloppy reps teach the sloppy version. Pick a pace that lets you stay accurate, then raise speed in small steps.

Use Chunk Drills, Then Stitch Back Together

Find the part that causes most errors, drill it, then reconnect it to the full routine. This keeps practice tight and stops you from repeating the easy parts while the hard part stays weak.

Keep Sessions Short And Frequent

Many skills respond well to shorter sessions that happen more often. You stay fresher, form stays cleaner, and you get more “start-up” practice, which is a real part of performance.

Add Mild Pressure Once The Form Holds

When the routine feels stable, add a timer, a new setting, or a slightly harder level. That checks whether the skill holds when attention is split.

Second Table: Pick The Right Method For Your Goal

Your Goal	Memory Type Lean	Try This
Remember names and dates	Declarative	Self-quiz, then revisit after a gap
Learn a keyboard shortcut	Procedural	20 slow correct reps, then speed up
Study for definitions	Declarative	Write the definition from memory, then check
Improve a sports shot	Procedural	Short sets with rest + feedback each set
Learn a speech	Mixed	Outline from memory, then rehearse aloud
Cook a new dish	Mixed	Memorize steps, then repeat until timing is steady
Play a song cleanly	Procedural	Metronome slow, then raise tempo weekly

How The Two Types Work Together

Declarative memory can set the rules and the plan. Procedural memory can carry out that plan quickly once the routine is trained.

Think about learning to drive. Early on, you recall rules: mirrors, signals, right-of-way. After months, shifting and mirror checks become automatic. You still use declarative memory for new routes or new traffic rules, while procedural memory runs the steady motions.

When Memory Changes Need Medical Help

Sudden confusion, dramatic changes, or memory issues paired with weakness, severe headache, or speech trouble are urgent warning signs. Seek emergency care.

For slower changes, a clinician can review sleep, stress load, medications, and medical causes.

Practical Takeaways

• Declarative and procedural memory are two types of long-term memory.
• Declarative memory stores facts and events you can state. Procedural memory stores skills you show through action.
• Facts improve with spaced recall and self-testing. Skills improve with clean repetition plus feedback.
• Most learning uses both systems, so match your method to what you’re trying to learn.
