Chapter 5 Self-Assessment Quiz
Cognitive Load: Why Your Brain Has RAM, Not Just a Hard Drive
Instructions: Take this quiz without looking back at the chapter. The goal is to discover what you actually retained versus what you merely recognize. After completing the quiz, check your answers using the key at the end. Notice which questions were easy, which were hard, and how your confidence compared to your performance — that's metacognitive calibration in action.

6. According to the chapter, when Diane Park explains a multi-step math problem to her son Kenji in a single unbroken stream of speech, she is primarily adding:
a) Intrinsic load — the math itself is too hard b) Germane load — Kenji is building schemas c) Extraneous load — the delivery method exceeds his working memory capacity d) Modality load — she should be writing instead of speaking
7. Chunking helps learning because:
a) It increases the raw capacity of working memory b) It groups individual items into larger meaningful units, each counting as a single item in working memory c) It eliminates the need for working memory entirely d) It converts short-term memory into long-term memory
8. In the chess expertise study by Simon and Chase, chess masters performed no better than beginners when:
a) They were given only five seconds to study the board b) The pieces were arranged randomly rather than in a real game position c) They played against a computer d) They were distracted by background noise
9. The expertise reversal effect is the finding that:
a) Experts learn more slowly than beginners in all conditions b) Beginners should always solve problems on their own rather than study worked examples c) Instructional techniques effective for beginners become ineffective or counterproductive for advanced learners d) Expertise makes learners resistant to all forms of instruction
10. A professor who reads PowerPoint slides aloud, word for word, while students read the same text on the screen is creating:
a) The split-attention effect b) The modality effect c) The redundancy effect d) Germane load
Section 2: True or False
Mark each statement as True or False. If false, briefly explain why.
11. Intrinsic load depends only on the material itself and is not affected by the learner's prior knowledge.
12. The modality effect suggests that presenting complementary information across visual and auditory channels reduces cognitive load compared to presenting everything through a single channel.
13. A schema is an isolated piece of information stored in working memory that helps with memorization.
14. Automation means that practiced skills no longer require conscious working memory resources, freeing up capacity for other processing.
15. The redundancy effect and spaced repetition are the same thing — both involve presenting the same information multiple times.
Section 3: Short Answer
Answer in 2-4 sentences. The effort of generating answers from memory is itself a learning strategy.
16. Explain the "cup" analogy for cognitive load. What are the three faucets, and what happens when the cup overflows?
17. Why did Mia Chen struggle with the chain rule in her calculus textbook? Distinguish between the contribution of intrinsic load and extraneous load to her difficulty.
18. How does schema formation change the way experts experience complex material compared to novices? Use a specific example from the chapter or create your own.
19. Describe two specific actions you can take to reduce extraneous cognitive load in your study materials.
20. Why should your study strategy change as you progress from beginner to intermediate to advanced in a subject? What should beginners use that experts should avoid, and why?
Answer Key
1. b) 3-5 items. Miller's original 1956 estimate was 7±2 for short-term memory, but Cowan's (2001) research revised the estimate for actively manipulated information downward to approximately 3-5 items.
2. b) John Sweller in the 1980s. Sweller was an Australian cognitive psychologist who developed cognitive load theory based on observations about problem-solving and worked examples.
3. c) Intrinsic load. It's determined by the element interactivity of the material and the learner's prior knowledge. You can manage it (by sequencing or building prerequisites), but you can't reduce it without changing the material itself.
4. b) The split-attention effect. When related information is physically separated, learners must mentally integrate it, consuming working memory resources that could be used for learning.
5. c) The cognitive effort devoted to building schemas and integrating new knowledge. Germane load is the "good" kind of cognitive effort — the kind that produces actual learning.
6. c) Extraneous load. The math problem itself (intrinsic load) is manageable when broken into steps, but Diane's rapid-fire delivery of nine cognitive operations in a single stream overwhelms Kenji's four-item working memory capacity. The overload comes from the presentation method, not the content.
7. b) It groups individual items into larger meaningful units, each counting as a single item in working memory. The raw capacity of working memory doesn't change — but each "slot" can hold a more information-rich chunk.
8. b) The pieces were arranged randomly rather than in a real game position. Masters' advantage comes from recognizing meaningful patterns (schemas) built from game experience. Random arrangements don't match any schema, so the masters' expertise provides no advantage.
9. c) Instructional techniques effective for beginners become ineffective or counterproductive for advanced learners. Specifically, detailed guidance and worked examples add extraneous load for experts who already have the relevant schemas.
10. c) The redundancy effect. Identical information presented in two formats simultaneously forces the learner to process both and verify they match — this adds extraneous load without adding learning value.
11. False. Intrinsic load depends on both the material's complexity AND the learner's prior knowledge. The same material has lower intrinsic load for someone who already has relevant schemas, because schemas compress multiple elements into single working memory items.
12. True. This is the modality effect — visual and auditory channels have separate processing capacities, so spreading complementary information across both effectively increases total processing capacity.
13. False. A schema is an organized mental framework stored in long-term memory that structures knowledge about a topic. It functions as a single unit in working memory, allowing complex information to be processed efficiently — the opposite of an isolated piece of information.
14. True. Automation is the process by which practiced skills become so fluent that they operate below conscious awareness, freeing working memory capacity for higher-level processing.
15. False. They are completely different. The redundancy effect involves simultaneous presentation of identical information in multiple formats within a single learning moment (which adds extraneous load). Spaced repetition involves reviewing the same material across different study sessions spread over time (which strengthens memory traces). One is harmful; the other is one of the most effective learning strategies known.
16. The cup represents working memory capacity — it holds a fixed amount. The three faucets are intrinsic load (complexity of the material), extraneous load (poor design and presentation), and germane load (the effort of building schemas and understanding). When the cup overflows — when total load exceeds capacity — germane load is the first to be sacrificed, meaning the learner works hard but builds no understanding.
17. Mia's struggle had two sources. The intrinsic load was genuinely high — the chain rule involves multiple interacting elements (function composition, derivatives, algebraic manipulation). But the extraneous load made it worse: the textbook split the diagram, the algebra, and the explanatory text across separate pages, forcing Mia to hold information from one page while flipping to another. The extraneous load consumed working memory that should have been available for building understanding of the chain rule itself.
18. Experts have schemas that compress complex information into single working memory items. For example, a chess master sees a board configuration as a single meaningful pattern (one chunk), while a beginner sees individual pieces on individual squares (many items). Both have the same working memory capacity, but the expert's schemas allow her to process the same board position using far fewer working memory slots, leaving capacity for strategic thinking.
19. Any two of: (1) Integrate physically separated information — place diagrams next to their explanations instead of on different pages. (2) Eliminate decorative or irrelevant elements that consume attention without contributing to understanding. (3) Avoid processing identical information in two formats simultaneously (e.g., don't read text that says exactly what a diagram already shows). (4) Use multimedia that combines visual and auditory channels (modality effect) rather than purely text-based materials. (5) Ensure instructions are clear so cognitive resources aren't spent decoding what to do.
20. Beginners should use worked examples and heavily scaffolded materials because they lack schemas — detailed guidance reduces extraneous and intrinsic load, freeing capacity for schema building. Experts should avoid these same materials because the expertise reversal effect means detailed guidance becomes redundant — the expert already has the schemas, so processing unnecessary explanations adds extraneous load. Experts learn more effectively from independent practice and less scaffolded challenges that strengthen and extend existing schemas.
Metacognitive Reflection
After checking your answers, take a moment to reflect:
- How many answers did you get right?
- Were there questions where you felt confident but were wrong? (That's an illusion of competence — a concept from Chapter 1.)
- Were there questions where you felt uncertain but were right? (That's the desirable difficulty of retrieval practice at work.)
- Which type of cognitive load gave you the most trouble to define and distinguish? Return to that section of the chapter for a focused re-read.
