WGU D186 Learning Science and Knowledge Retention (D186) 2026
1. Which process involves moving information from temporary working memory
into long-term memory storage?
A. Decoding
B. Encoding
C. Pruning
D. Interference
Answer: B
Rationale: Encoding is the crucial step of converting sensory input into a form that can be
stored in long-term memory.
2. According to the Ebbinghaus Forgetting Curve, when does the most rapid
decline in memory retention occur?
A. One week after learning
B. Immediately after learning
C. One month after learning
D. During the sleep cycle
Answer: B
Rationale: The forgetting curve shows that memory loss is steepest within the first 24
hours of acquiring new information.
3. What is ‘Retrieval Practice’ primarily focused on?
A. Actively pulling information from memory
B. Highlighting key terms in a guide
C. Reading a textbook multiple times
D. Listening to lectures passively
Answer: A
,Rationale: Retrieval practice involves the active recall of information, which strengthens
neural pathways and enhances long-term retention.
4. Which concept describes the cognitive capacity limit of working memory?
A. Miller’s Law (7±2)
B. The Law of Effect
C. The Protégé Effect
D. Neuroplasticity
Answer: A
Rationale: George Miller’s research suggested that the average human working memory
can hold approximately seven plus or minus two pieces of information.
5. In Cognitive Load Theory, what is ‘Extraneous Load’?
A. The inherent difficulty of the subject material
B. Distractions or poorly designed instructions
C. The effort used to create permanent schemas
D. The emotional state of the learner
Answer: B
Rationale: Extraneous load refers to mental effort that does not contribute to learning,
often caused by poor instructional design.
6. What is the ‘Testing Effect’?
A. The anxiety students feel before an exam
B. The curve representing how many questions students miss
C. The tendency to forget information after an exam is over
D. The phenomenon where taking a test improves memory more than studying
Answer: D
Rationale: The Testing Effect shows that the act of being tested on material strengthens
long-term retention more effectively than re-reading.
, 7. Which technique involves alternating between different topics or types of
problems within a single study session?
A. Interleaving
B. Chunking
C. Blocking
D. Massed Practice
Answer: A
Rationale: Interleaving is the practice of mixing different topics, which forces the brain to
distinguish between concepts more effectively.
8. What does ‘Metacognition’ mean?
A. Learning through movement
B. Thinking about thinking
C. Socially mediated learning
D. Subconscious memorization
Answer: B
Rationale: Metacognition is the awareness and understanding of one’s own thought
processes and learning strategies.
9. Which term refers to the brain’s ability to reorganize itself by forming new
neural connections?
A. Fixed Mindset
B. Neuroplasticity
C. Cognitive Dissonance
D. Synaptic Pruning
Answer: B
Rationale: Neuroplasticity allows the brain to adapt and change physically in response to
new experiences and learning.
