Sensory, Short-term & Long-term Memory FI.I.B.K14

Why This Matters

When you explain a new concept or maneuver, the words hit your student's senses, get held for a few seconds, and then, if you've done it right, get filed away for good. That's three different memory systems doing three different jobs. Understanding each one is how you teach so the material reaches the last stage and stays.

The Three-Stage System

Memory works like a computer: input, processing, storage, retrieval. Information moves through three stages, and most of it gets dropped along the way.

Sensory → Short-Term → Long-Term

The instructor's job is getting the stuff that matters all the way to the end.

Sensory Memory

Every sight, sound, and sensation hits sensory memory first. It holds everything for a split second, scans for what matters, and discards the rest within seconds.

• The filter is the student's own sense of what's important (not yours)

• Dramatic or multi-sensory input is more likely to survive the cut (a fire alarm cuts through anything)

• What survives gets passed to short-term memory; this hand-off process is called precoding

The CFI takeaway: If your student's sensory filter doesn't flag something as important, it's gone before learning even starts. Make it matter, and make it vivid.

Short-Term Memory

STM is the control tower - coordinating everything coming in and going out. But it's sharply limited:

• ~30 seconds of retention

• ~7 chunks of capacity

• Takes 5–10 seconds to code information - and if you interrupt that coding, it's lost

Two things move information through STM instead of losing it: rehearsal (repetition) and chunking (sorting into systematic groups). And the real key is recoding: relating new information to what the student already knows. That's where actual learning begins.

The CFI takeaway: Don't fire-hose. Seven chunks, thirty seconds. Feed information in small groups, give it time to code, and don't interrupt the student mid-process.

Long-Term Memory

This is permanent, unlimited storage - but information only gets here two ways:

• Significance: It mattered (no pilot forgets their first solo)

• Repetition: It was rehearsed enough to stick

LTM is organized into schemas, or mental frameworks that connect related knowledge. And critically, LTM is a reconstruction, not a recording - it's rebuilt on recall, subject to bias and error. That's why two pilots describe the same event differently.

The CFI takeaway: Activate the schema before you build on it. A two-minute review of the last lesson "switches on" the framework, so the new material has somewhere to attach. Meaningful beats rote every time.

What This Looks Like

You're teaching steep turns in the brief.

• Sensory: You demonstrate with a model and your hands, talk through it, use images, and have the student feel the control inputs. Multi-sensory - it clears the filter.

• Short-term: You don't dump all twelve steps at once. You group them - entry, sight picture, recovery - three chunks, not twelve. You pause and let each one code.

• Recoding: You tie it to something they already own: "It's a level turn with more bank and back pressure. You already know level turns." The new attaches to the known.

• Long-term: Next lesson, you open with a 60-second review to fire up the schema before flying. The framework's already warm when the new material arrives.
