Memory Strategies and Cognitive Techniques in Learning

Bower et al. — Self-Organized vs. Unorganized Words

Participants remembered many more words when they organized the list themselves.

Bower et al. — Hierarchical Organization

Words arranged in a hierarchy/tree structure were recalled far better than random lists.

How Organization Helps

Reduces memory load, creates meaningful connections, provides retrieval cues.

Memory Span

Amount of information a person can hold briefly in working memory.

Average Adult Memory Span

About 7 ± 2 items (modern estimates closer to 4 chunks).

Chunking and Memory Span

Chunking groups small items into larger meaningful units.

Rajan's Exceptional Memory for Pi

Rajan memorized huge numbers of digits by turning digits into meaningful chunks/stories.

Chase & Ericsson — Practice with Chunking

Participant SF improved digit span from ~7 to over 80 digits using practice and chunking.

How Chunking Helps

Makes information meaningful, reduces number of separate units to remember.

Two Imagery Mnemonics with Organization

Method of loci, Pegword system.

Organization in Imagery Mnemonics

Organized mental structure helps retrieval sequence and cueing.

Outlining — Activities

Identify main ideas, organize relationships, prioritize information.

Four Thinking Processes in Outlining

Selecting, organizing, connecting, synthesizing.

Research on Outlining

Effective when students actively generate outlines themselves.

Massed vs. Spaced Study

Massed = cramming in one session. Spaced = spread across time.

Hall's Spacing Study

Spaced repetitions improved retention over massed practice.

Dempster's Findings

Spacing effect is one of the most reliable memory findings.

Spacing Effect

Learning is stronger when study sessions are separated in time.

Kornell's Study on Different Spacing

Moderate spacing produced best long-term retention.

Within- vs. Between-Session Spacing

Within: breaks inside one session. Between: separate study days.

Lag Effect vs. Spacing Effect

Spacing effect = spacing helps. Lag effect = longer gaps can help more (up to a point).

Utility (Dunlosky et al., 2013)

Combination of effectiveness + practicality for learning strategies.

Utility Rating for Spacing

High utility.

Kornell on Cramming

Cramming can help short-term tests but hurts long-term retention.

Reasons to Avoid Cramming

Faster forgetting, poor transfer, more fatigue/stress, illusion of mastery.

Grouping vs. Interleaving

Grouping = same topic together. Interleaving = mix different topics/problems.

Learner Beliefs vs. Results

Students prefer grouping. Interleaving usually produces better learning.

Rohrer & Taylor — Math Problems

Interleaved practice improved later test performance dramatically.

How Taylor & Rohrer Controlled for Spacing

Total time and spacing held constant; only order differed.

When Interleaving Helps Most

When students must discriminate between problem types.

In-Class Testing Exercise

Retrieval practice improved later memory more than rereading.

Wheeler & Roediger

Testing some material improved retention of both tested and related material.

Controlling Exposure in Testing Studies

Study time/exposure matched across conditions.

Carpenter & DeLosh

Testing still outperformed restudying even with equal exposure.

Testing Effect

Retrieving information strengthens memory more than rereading.

Rowland Review

Majority of studies show strong testing benefits.

Two Uses of Tests

Assessment and learning enhancement.

Karpicke & Roediger

Repeated retrieval beat repeated studying.

Roediger & Karpicke — Passages

Restudying helped immediate tests. Testing helped delayed tests.

Testing in Real Classrooms

Frequent quizzes improve exam performance.

Testing and Inference Questions

Testing can improve deeper understanding and inference.

Testing and Non-Tested Information

Retrieval can spread benefits to related knowledge.

Learner Beliefs

Students often underestimate testing benefits.

Direct vs. Indirect Benefits

Direct = stronger memory. Indirect = better metacognition and study guidance.

5 Ways to Apply Testing Effect

Practice quizzes, flashcards, self-testing, free recall summaries, teaching others.

Highest Utility Methods

Practice testing, distributed practice (spacing).

Combining Testing + Spacing

One of the strongest learning combinations.

Cues

Encoding = getting info into memory. Retrieval = accessing stored info.

Cue Dependency of Memory

Recall depends heavily on available retrieval cues.

Tulving & Pearlstone

Cued recall greatly exceeded free recall.

Mantyla Study

Self-generated cues worked best.

Thieman Results

Same cue at study and test produced best recall.

Fisher & Craik

Best memory occurred when encoding and retrieval matched.

"Learning Does Not Occur in Isolation"

Context becomes linked with memories.

Godden & Baddeley — Underwater Study

Best recall when learning/testing contexts matched.

Goodwin et al. — Alcohol

Recall improved when intoxication state matched.

Eich & Metcalf — Mood

Mood-congruent states improved recall.

Contextual Cue Literature

Effects exist but are usually modest in real life.

Saufley et al. — Matching Classrooms

Same classroom gave slight benefit.

Why Exact Same Classroom Isn't Necessary

Most classroom cues are not unique enough.

Unique Cues

Distinctive personal cues aid retrieval best.

Non-Unique vs. Unique Cues

Weak: classrooms, general environments.

Weak Cues

Classrooms, general environments.

Strong Cues

Emotions, personal associations, self-generated cues.

Insight

Sudden realization of a solution.

Creativity as Insight

Creativity often involves novel connections leading to insight.

Two Common Beliefs About Creativity

Creativity is magical. Creative people are fundamentally different.

Why Those Beliefs Are Wrong

Historical discoveries usually involved extensive knowledge/work.

Kepler's Discovery

Resulted from ordinary reasoning processes.

Nothing Special View

Creativity uses normal cognitive processes.

Role of Knowledge in Insight

Deep knowledge supports creative solutions.

Two Causes of Insight Problems

Mental set, functional fixedness.

Solving by Analogy

Applying a known solution to a new problem.

Transfer by Analogy

Transfer by analogy is poor unless similarities are noticed.

Primary Cause of Transfer Failure

Failure to notice deep similarities.

Two Methods to Improve Transfer

Compare multiple examples, explicitly explain underlying principles.

Mental Set

Tendency to stick with familiar strategies.

Functional Fixedness

Seeing objects only in typical ways.

Three Key Elements for Insight

Knowledge, flexibility, recognition of patterns.

Collaborative Learning

Learning with others through shared discussion and retrieval.

Four Benefits of Group Study

Exposure to new perspectives, retrieval practice, error correction, motivation/accountability.

Memory is Malleable

Memories can be altered after encoding.

Misinformation Effect

Post-event info changes memory.

Four Ways to Reduce Memory Errors

Verify sources, test individually first, use notes, encourage correction/discussion.

Highlighting and Doodling

Highlighting alone produced weak learning.

When Highlighting Helps

Useful if selective and combined with active strategies.

Two Ways Drawing Helps

Deeper processing, multiple memory codes (visual + verbal).

Five Effects of Sleep Deprivation

Worse attention, poor memory, slower reaction time, mood problems, reduced decision-making.

Short-Term Diet Suggestions

Stay hydrated, eat balanced meals, avoid excessive sugar crashes, don't skip meals.
