Introduction
This comprehensive test bank is designed to prepare students for the WGU
C180 Foundations of Psychology Objective Assessment. It covers all eight
core competencies, including research methods, neurobiology,
developmental milestones, social cognition, learning theories, intelligence
and memory, emotion and personality, and psychological disorders. The
questions range from foundational knowledge to applied scenarios,
ensuring a thorough review of key concepts. Each question includes a
verified correct answer and a detailed rationale to reinforce
understanding. This resource is ideal for self-assessment and exam
preparation, helping students identify strengths and areas for
improvement before taking the OA.
,Section One: Questions 1–200
1. Psychology is formally defined as the scientific study of:
A. The brain and its physical structures.
B. Behavior and mental processes.
C. Unconscious drives and conflicts.
D. Social interactions and group dynamics.
B
RATIONALE: Psychology is the scientific study of behavior
(observable actions) and mental processes (internal experiences such
as thoughts, emotions, and perceptions). While the brain, unconscious
drives, and social interactions are all areas of study within psychology,
the most comprehensive and formal definition encompasses both
behavior and mental processes.
2. Which of the following research methods is best suited for
determining cause-and-effect relationships?
A. Naturalistic observation.
B. Correlational study.
C. Experimental design.
D. Case study.
C
RATIONALE: Only an experimental design, with its manipulation of
an independent variable and control of extraneous variables, can
establish cause-and-effect relationships. Correlational studies identify
relationships but not causation, while naturalistic observation and case
studies are descriptive methods that do not manipulate variables.
3. The neuron's resting potential is primarily maintained by:
A. The sodium-potassium pump.
B. The release of neurotransmitters.
,C. The action potential.
D. The myelin sheath.
A
RATIONALE: The sodium-potassium pump actively transports sodium
ions out of the neuron and potassium ions into the neuron, maintaining
the negative resting potential. Neurotransmitters are released during
synaptic transmission, the action potential is a brief electrical charge,
and the myelin sheath insulates the axon to speed transmission.
4. According to Piaget, a child in the preoperational stage is most likely
to struggle with which concept?
A. Object permanence.
B. Conservation.
C. Abstract reasoning.
D. Hypothetical thinking.
B
RATIONALE: The preoperational stage (ages 2–7) is characterized by
egocentrism and a lack of conservation—the understanding that quantity
remains the same despite changes in shape or appearance. Object
permanence is achieved in the sensorimotor stage, while abstract and
hypothetical reasoning develop in the formal operational stage.
5. In classical conditioning, the unconditioned stimulus (US) is a stimulus
that:
A. Naturally and automatically triggers a response.
B. Is originally neutral but becomes associated with a conditioned
stimulus.
C. Is learned through reinforcement.
D. Requires repeated pairings to produce a response.
A
, RATIONALE: The unconditioned stimulus (US) is one that naturally
and automatically triggers an unconditioned response (UR) without any
prior learning. An example is food (US) causing salivation (UR). The
neutral stimulus becomes a conditioned stimulus (CS) only after pairing
with the US.
6. Which part of the brain is most critical for forming new explicit
memories?
A. Amygdala.
B. Cerebellum.
C. Hippocampus.
D. Hypothalamus.
C
RATIONALE: The hippocampus plays a vital role in the consolidation
of explicit (declarative) memories—facts and events. The amygdala is
involved in emotional memories, the cerebellum in implicit/procedural
memories, and the hypothalamus in regulating basic drives like hunger
and thirst.
7. A researcher wants to study the relationship between hours of sleep
and academic performance. Which research method would be most
appropriate?
A. Experiment.
B. Correlational study.
C. Naturalistic observation.
D. Case study.
B
RATIONALE: A correlational study is appropriate for examining the
relationship between two variables without manipulating them. An
experiment would require manipulating sleep hours, which may be
unethical or impractical. Naturalistic observation and case studies would
not provide quantitative data on the relationship.
