Section 1: Foundations of Learning Science
Learning Theories, Research Methods, & Neuroscience of Learning | Q1-Q20
This section tests foundational knowledge of behaviorism, cognitivism, constructivism, social cognitive theory,
research methodologies, and the neuroscience of learning.
Q1: A third-grade teacher rewards students with tokens every time they raise their hand before
speaking, then allows them to exchange tokens for small prizes on Friday. Which learning theory best
explains why this practice increases hand-raising behavior?
A. Operant conditioning, because the tokens function as secondary reinforcers that strengthen
the preceding behavior. [CORRECT]
B. Classical conditioning, because the tokens elicit an involuntary hand-raising response.
C. Social learning theory, because students imitate peers who receive tokens.
D. Constructivism, because students actively construct an understanding of classroom norms.
Correct Answer: A
Rationale: Operant conditioning (Skinner) explains how consequences shape voluntary behavior. Tokens are
secondary reinforcers paired with primary rewards, and receiving a token after hand-raising positively
reinforces that behavior. Classical conditioning (option B) pairs stimuli to elicit involuntary responses, not
voluntary ones. Social learning theory (option C, Bandura) emphasizes observational learning and imitation,
not direct reinforcement. Constructivism (option D) focuses on knowledge construction, not behavioral
conditioning. WGU D664 verification: this is the canonical Skinner operant conditioning application.
Q2: A high school science teacher wants students to understand that light travels in waves by having
them design experiments, gather data, and revise their explanations over several lessons. This
instructional approach most directly reflects which theoretical perspective?
A. Behaviorism, because students are reinforced for correct hypotheses.
B. Cognitivism, because the teacher emphasizes internal mental representations.
C. Constructivism, because students actively build understanding through experience and
reflection. [CORRECT]
D. Social cognitive theory, because students learn by observing scientists.
Correct Answer: C
Rationale: Constructivism (Piaget, Vygotsky, Bruner) holds that learners actively construct knowledge
through experience, reflection, and revision. Having students design experiments and revise explanations is a
hallmark of constructivist pedagogy. Behaviorism (option A) reduces learning to observable behavior change,
not conceptual revision. Cognitivism (option B) addresses internal representations but does not emphasize
learner-driven inquiry. Social cognitive theory (option D) emphasizes observation and modeling, not personal
experimentation. WGU D664 verification: inquiry-based science exemplifies constructivism.
Q3: Which statement correctly distinguishes Bandura's social cognitive theory from earlier
behaviorist views?
A. Bandura argued that learning requires direct reinforcement of the learner's own behavior.

,WGU D664 | Learner and Learning Science | Objective Assessment Prep 2026/2027 Edition - 192 Questions
B. Bandura introduced the concepts of observational learning, modeling, and self-efficacy as
central to learning. [CORRECT]
C. Bandura rejected the role of cognitive processes such as attention and retention.
D. Bandura claimed that behavior is determined solely by environmental stimuli.
Correct Answer: B
Rationale: Bandura's social cognitive theory added observational learning, modeling, and self-efficacy to the
learning picture, demonstrating that humans can learn without direct reinforcement. The Bobo doll studies
showed children imitate modeled aggression. Option A is behaviorist, not Bandura. Option C is false;
Bandura explicitly included attention, retention, reproduction, and motivation. Option D describes radical
behaviorism, which Bandura rejected by adding personal and behavioral factors to the reciprocal triad. WGU
D664 verification: Bandura's triadic reciprocal causation is a required concept.
Q4: A researcher randomly assigns 80 fifth-graders to either a retrieval-practice condition or a
re-reading condition, then compares their performance on a delayed post-test. This design is best
described as:
A. Correlational, because the researcher compares two groups.
B. Quasi-experimental, because the participants are children.
C. A true experiment, because participants were randomly assigned to conditions. [CORRECT]
D. A case study, because the researcher focuses on a single classroom phenomenon.
Correct Answer: C
Rationale: True experiments require random assignment to conditions, manipulation of an independent
variable, and comparison of outcomes. Random assignment controls for confounds and supports causal
inference. Quasi-experimental (option B) is used when random assignment is not possible, such as intact
classrooms. Correlational (option A) does not involve manipulation or random assignment. Case study
(option D) is an in-depth examination of a single instance, not a group comparison. WGU D664 verification:
random assignment is the defining feature of a true experiment.
Q5: A school district wants to evaluate a new reading program but cannot randomly assign students
because classrooms are already formed. Researchers compare two existing classrooms, one using the
new program and one using the standard curriculum. This is best described as:
A. A true experiment, because two groups are being compared.
B. A quasi-experiment, because intact groups are used rather than random assignment.
[CORRECT]
C. A correlational study, because the researcher examines relationships.
D. A longitudinal study, because the program lasts all year.
Correct Answer: B
Rationale: Quasi-experimental designs use pre-existing groups when random assignment is impractical.
They allow causal inferences but with more threats to internal validity (e.g., selection bias). True experiments
(option A) require random assignment. Correlational studies (option C) measure relationships without
intervention. Longitudinal designs (option D) track change over time and may be experimental or not. WGU
D664 verification: intact-group comparisons are textbook quasi-experiments.

Q6: Researchers find that students who report more hours of independent reading per week also have
higher vocabulary scores. The most accurate interpretation is:
A. Independent reading causes higher vocabulary scores.
B. Higher vocabulary scores cause more independent reading.
C. The two variables are correlated, but causation cannot be inferred. [CORRECT]
D. There is no meaningful relationship between the variables.
Correct Answer: C
Rationale: Correlation does not imply causation. A third variable (e.g., parental education, motivation, prior
language exposure) could account for both. Without manipulating reading time and randomly assigning
students, cause and effect cannot be established. Options A and B assert unsupported causal directions.
Option D contradicts the described positive correlation. WGU D664 verification: interpreting correlations is a
foundational research-literacy skill.
Q7: Which finding best illustrates neuroplasticity in adult learners?
A. Adults show no change in brain structure after learning a new skill.
B. London taxi drivers show enlarged posterior hippocampi after extensive navigation training.
[CORRECT]
C. Brain development stops at age 18, so adults cannot learn new languages.
D. Neural pathways are fixed after early childhood.
Correct Answer: B
Rationale: Neuroplasticity refers to the brain's ability to reorganize itself by forming new neural connections
throughout life. Maguire et al.'s taxi driver study demonstrated structural hippocampal enlargement tied to
spatial learning. Options A, C, and D reflect outdated beliefs that the adult brain is fixed. WGU D664
verification: Maguire's taxi driver study is a canonical neuroplasticity example and adult learning is supported
by ongoing myelination and synaptic change.
Q8: Myelination is best described as:
A. The pruning of unused synapses during early childhood.
B. The formation of a fatty sheath around axons that increases the speed of neural impulses.
[CORRECT]
C. The process by which neurons generate action potentials.
D. The death of neurons that occurs naturally with aging.
Correct Answer: B
Rationale: Myelination is the wrapping of axons in a myelin sheath produced by oligodendrocytes (CNS) or
Schwann cells (PNS), which insulates the axon and enables saltatory conduction, dramatically increasing
signal speed. Synaptic pruning (option A) is a different process. Action potentials (option C) are electrical
signals, not myelination. Apoptosis (option D) is programmed cell death. WGU D664 verification:
myelination continues into the twenties and supports higher-order cognition.
Q9: A first-grade teacher uses mnemonic pictures to help students remember letter-sound
correspondences (for example, an apple for 'a'). Which learning theory does this most directly reflect?
