WGU D664 Objective Assessment –
Learners and Learning Science (2026)
About This Exam Bundle
This comprehensive review contains 220+ exam-
style questions designed to prepare candidates for
the WGU D664 Learners and Learning Science
Objective Assessment. The material covers brain
structures, learning theories, memory processes,
developmental stages, and evidence-based
instructional strategies .
Primary OA Coverage Areas:
- Brain Structure & Function (Neuroscience)
- Memory & Information Processing (Encoding,
Storage, Retrieval)
- Metacognition & Executive Function
1
,- Learning Theories (Behaviorism, Cognitivism,
Constructivism, Humanism)
- Cognitive Development (Piaget, Vygotsky,
Erikson)
- Instructional Strategies (Spacing, Interleaving,
Retrieval Practice, Scaffolding)
- Motivation & Engagement (Self-Determination
Theory)
- Learning Myths & Neurodiversity
- Assessment & Feedback
SECTION A: BRAIN STRUCTURE &
FUNCTION (NEUROSCIENCE)
(Questions 1-25)
2
,1. Which brain region is primarily responsible for
automatic functions such as heartbeat and breathing?
- A) Prefrontal Cortex
- B) Limbic System
- C) Brain Stem
- D) Cerebellum
Answer: C) Brain Stem
Rationale: The brain stem connects the brain to the
spinal cord and oversees vital automatic functions,
including heart rate regulation, breathing, blood flow
management, and reflexes like sneezing and
swallowing. Unlike higher brain regions involved in
cognition or emotion, the brain stem controls these
essential life-sustaining processes unconsciously .
3
, 2. Which brain structure is considered the emotional
control center, deeply involved in feelings of
happiness, fear, and sadness?
- A) Cerebellum
- B) Prefrontal Cortex
- C) Limbic System
- D) Brain Stem
Answer: C) Limbic System
Rationale: The limbic system, located deep within
the brain, plays a critical role in managing emotions
and emotional memory. It helps regulate feelings
such as happiness, fear, and sadness, influencing
behavior and motivation .
3. What is the main function of the prefrontal cortex
in cognitive processing?
