WGU D664 – The Science of Learning Objective Assessment |
2025/2026 Latest Verified Questions and Correct Answers | Updated
Edition | Graded A+
Introduction
The WGU D664 Science of Learning Exam evaluates how the brain processes, stores, and retrieves
information. It explores the relationship between neuroscience and learning, covering the cerebrum,
hippocampus, prefrontal cortex, brainstem, neuroplasticity, memory, and stress effects. Each question
includes a verified correct answer and a concise rationale to promote exam readiness and cognitive
mastery.
Answer Format
All correct answers are highlighted in bold and green, with rationales explaining key concepts and the
reasoning behind each choice.
1. How does cramming affect the cerebrum?
a) Supports strong memory formation
b) Overwhelms the cerebrum, impairing cognitive functions
c) Maximizes long-term retention
d) Improves mental organization
Rationale: Cramming floods the cerebrum with excessive information in a short time, exceeding
its processing capacity. This results in confusion, poor retention, and weak long-term memory
formation.
2. True or False:
Multitasking can reduce the brainstem’s ability to regulate basic physiological functions.
True
Rationale: When multitasking increases cognitive demand, it diverts brain resources away from
basic regulation functions in the brainstem, which can temporarily disrupt breathing and heart
rate patterns.
3. What effect can multitasking have on the cerebrum?
a) Strengthens memory consolidation
b) Overwhelms its limited capacity and impairs cognitive functions
, c) Increases creativity
d) Simplifies decision-making
Rationale: The cerebrum manages higher-order thinking, problem-solving, and attention.
Dividing attention between tasks reduces focus, learning efficiency, and information retention.
4. The primary function of the hippocampus is:
a) Regulating motor skills
b) Maintaining focus and forming memories
c) Managing stress responses
d) Controlling involuntary actions
Rationale: The hippocampus forms new memories and supports concentration and learning.
Damage to this region can result in difficulty storing and recalling information.
5. What does the “myth of normal” refer to from a science of learning perspective?
a) There is a single, universally optimal learning style or cognitive functioning
b) Everyone learns differently
c) Only abnormal brains have learning challenges
d) Cognitive abilities are always flexible
Rationale: The “myth of normal” is the false belief that there is one correct or ideal way to
learn. Neuroscience confirms that learning varies across individuals due to differences in brain
wiring and experiences.
6. Which brain region is most active during deep thinking and reasoning?
a) Cerebellum
b) Brainstem
c) Occipital lobe
d) Prefrontal cortex
Rationale: The prefrontal cortex controls critical thinking, problem-solving, and decision-making,
making it essential for complex learning and planning.
7. Chronic sleep deprivation primarily disrupts which brain function?
a) Vision processing
b) Memory consolidation and focus
c) Reflex response
d) Balance coordination
Rationale: Sleep supports hippocampal activity that solidifies learning and memory. Without
rest, neural connections weaken, reducing concentration and recall.
