Unit 2 · 2.4
Encoding Memories
Unit 2 is 15–25% of the multiple-choice section. Encoding items punish the story that highlighting, 2× playback, and ‘I looked at it’ are the same as getting information in. · about 5 minutes with the essay beats.
You do not remember what happened. You remember what you encoded — and what later got in the way.
Read the scene first. The term will wait. When it lands, you will be able to use it on a stranger’s story — that is the exam, and that is also why this subject is interesting.
A scene you already lived
Do not hunt the term yet. Let this sit. The exam will hand you a stranger’s version of the same night.
You highlight an entire biology page until it glows. It feels like work. A sibling asks what the page actually said, and you can name the color of the highlighter better than the cycle. Then you try explaining the cycle in ordinary sentences, as if teaching. The second move hurts more and sticks more. Highlighting can be looking. Explaining is encoding with meaning. Playing a lecture at 2× while gaming is not a secret third encoding system. It is divided attention wearing a productivity costume. The exam wants the study move that is actually an encoding move — and it wants you to spot a design that tests encoding rather than retrieval.
What the paper actually asks
These are the scoring targets. If you can do them on a new story, you are ready — flashcards can wait.
- Apply levels of processing, chunking, and mnemonic strategy to a study plan.
- Separate automatic from effortful encoding.
- Spot a design that tests encoding, not retrieval.
The mechanism
Once you can walk this, you will start seeing it at dinner, in a group chat, in your own delay. That is the fun of this course.
Automatic encoding: some information lands with little intention — the gist of a conversation, where you sat, the time of day. Effortful encoding: you work to get it in — a formula, a list of terms, a route you will need tomorrow. Intention is not magic. The quality of the work matters.
Levels of processing: shallow encoding stays with surface features (the font, whether a word is in capitals, the highlighter color). Deep encoding ties the item to meaning, examples, and what you already know. Deep is not a moral word; it is a processing word. Chunking packs bits into meaningful units so a limited workspace can hold more. Spacing (distributed practice) beats a single massed cram for durable encoding. Testing yourself while you study is an encoding/study move, not a punishment — generating the item builds a better trace than restudying the glowing page. Mnemonics (peg words, palaces, acronyms) are deliberate encoding devices. Dual coding: pairing verbal material with an image can help; it is an idea with limits, not a promise that every doodle is science and not a claim you have two separate brains.
A design that tests encoding varies how material is gotten in (deep vs shallow instructions, chunked vs raw, spaced vs massed, tested vs restudied) and then uses the same retrieval test. A design that tests retrieval varies cues, context, or test type (recall vs recognition) after encoding was the same. If the stem changes the test and keeps study identical, you are probably on 2.6’s turf. If it changes how they studied and keeps the test identical, you are on this page.
Automatic
no deliberate effort
Effortful
attention and work
Shallow
looks / sound
Deep
meaning, links, self
Chunking
group to hold more
Spacing / testing
encode by retrieving later
Words worth owning
A definition is a tool. The confusable is the distractor. Learn both and the clever wrong answer stops working.
Automatic encoding
Getting information in with little deliberate effort — often gist, place, or sequence you did not try to memorize.
Confusable. Effortful encoding is the work you do on purpose. Automatic is not ‘better,’ just less intentional.
Effortful encoding
Deliberate work to get information into memory — rehearsal with meaning, organization, practice.
Confusable. Not the same as highlighting. Effort that stays shallow can still fail.
Levels of processing
Shallower encoding of surface features vs deeper encoding of meaning; deeper processing tends to support later memory.
Confusable. Not a moral ranking of students. Not automatic vs effortful (you can effortfully stay shallow).
Chunking
Grouping bits into meaningful units so a limited workspace can handle more.
Confusable. Not spacing (when you study). Not a mnemonic story unless the chunk itself is the device.
Spacing (distributed practice)
Spreading study over time rather than massing it in one block; tends to support more durable encoding.
Confusable. The testing effect is about retrieving as a study move, not about the calendar. Both can be used together.
Testing effect (as a study move)
Trying to produce the material during study — self-testing — tends to encode it more strongly than restudying.
Confusable. A later exam is a retrieval test (2.6). Using a quiz while studying is an encoding/study strategy on this page.
Mnemonic
A deliberate encoding device — acronym, peg, palace, story — that organizes to-be-remembered material.
Confusable. Not automatic encoding. Not dual coding unless an image is actually paired with the words.
Dual coding
The idea that pairing verbal material with imagery can strengthen encoding. A useful idea with limits, not a doodle guarantee.
Confusable. Not two memory stores (that is 2.5). Not proof of left-brain/right-brain study styles.
A study you can actually use
Classic or labeled hypothetical. Either way: what was done, what was found, what it cannot claim.
Classic (classroom-common) · 1970s (classroom-common)
Levels-of-processing classroom demonstration (Craik-style)
- What was done
- Classroom-common account: people judge words in different ways — surface (typeface, capitals) versus meaning (does it fit a sentence, is it pleasant) — and are later tested, often by surprise, on the same words.
- Finding
- Meaning judgments tend to produce better later memory than surface judgments. How you encode, not only that you ‘saw’ the word, matters.
- Limit — what it cannot claim
- A word list is not a chemistry course. Later critiques exist; treat this as a teaching demonstration of processing depth, not a law that every deep task always wins. Do not invent a percentage or a journal issue.
- How AAQ would probe it
- Method: experiment (orienting task as IV). DV: later memory test held constant — that is how you know you tested encoding. Limit: words, that sample, surprise test.
Labeled hypothetical
Hypothetical highlighting vs explaining, same later test (original practice source, not a published paper)
Original practice source, not a published paper.
- What was done
- A teacher randomly assigns 36 students to spend 15 minutes on the same page either highlighting as they wish or writing an explanation a younger sibling could use. The next day everyone takes the same blank-definition test.
- Finding
- If the explanation group produces more accurate definitions, a fair claim is that the encoding activity differed — not that highlighting ‘destroys memory,’ and not that the test measured a different retrieval cue for each group (the test was the same).
- Limit — what it cannot claim
- Labeled hypothetical. Fifteen minutes, one page, one class. Highlighting might include some meaning for some students; the IV is messy unless the teacher operationalizes ‘highlight only’ vs ‘explain without looking.’ Do not cite this as a real paper.
- How AAQ would probe it
- This is an encoding design: study activity varies, test is held constant. Method: experiment. IV: highlight vs explain. DV: blank-definition score. Contrast: a retrieval design would have given everyone the same study and then varied cues or test type.
Someone’s Tuesday
If it only lives in the textbook, it will not survive a novel stem. This is the idea wearing ordinary clothes.
A long ID number is hopeless as ten digits and easy as a date plus a bus route: chunking. Vocabulary you only ever saw in yellow ink dies on a blank line: shallow encoding that felt like studying. A mnemonic for the cranial-nerve list is effortful and a bit silly and often works. Drawing the water cycle while naming it is dual coding as an idea, not a personality type. Gaming through a 2× lecture leaves you with jokes from the game: divided attention, not a hack. Automatic: you did not try to memorize who sat where, and you still can. Effortful: the formula did not land until you generated it twice.
Where clever students go wrong
The trap is usually a neighboring term that almost fits. Name it so it stops feeling smart.
‘Highlighting is studying’ — only if the highlighter is doing meaning work, which it often is not. ‘I encode by playing a lecture at 2× while gaming’ is divided attention, not an encoding system. Dual coding is not left-brain/right-brain study advice. A surprise quiz in class is still a retrieval test if the stem is about cues at test; it is an encoding/study move if the stem is about how they learned before a later, same test. Read which variable moved.
A stem, then the move
Watch me work one. Then you will do four without looking back.
Scenario
Two classes get the same 20 terms. Class A highlights the glossary. Class B spends the same minutes making a question for each term and answering it from memory. Friday, both write definitions on a blank sheet. Which process is the study designed to test, and which encoding claim is fairest?
Walkthrough
Study method varies; the Friday test is the same. That is an encoding design, not a retrieval-cue design. Class B is using testing as a study move and deeper processing (generating meaning). Class A may be staying shallow. Do not conclude that highlighting is never useful; conclude that in this design, generating beat restudying-by-color if B scores higher. Do not call this automatic encoding — both groups intended to learn.
The move
Encoding is what the design tests (same retrieval test, different study). Fairest claim: effortful, deeper, generative study vs shallow looking — not a verdict on highlighters as objects.

A living experiment, not a vibe
Do this on your actual Tuesday. The paper will later hand you a stranger’s version of the same five minutes.
Pick four terms. For two, only underline. For two, explain each to an empty chair or a sibling in one spoken sentence, then write the sentence from memory. No shame contest — log which pair you can still say.
Prove it
Four items. No looking back.
One at a time. After each submit I will show the key, why it is right, and why the others felt clever.

Encoding design vs retrieval design
Say the move in your own mouth. If you can write it, you own it — rereading is not the same thing.
Original practice source, not a published paper. Study 1: students are randomly assigned to highlight or to explain the same page, then all take the same blank-definition test. Study 2: all students explain the page, then half are tested in the same room and half in a different hall. Identify the research method of Study 1. Then state which study is built to test encoding and which is built to test retrieval, and name one variable as Study 1 uses it.
Move: Hold the test, vary study → encoding. Hold study, vary test context → retrieval (2.6). Method of Study 1: experiment. IV: highlight vs explain.
