,WGU C180 ENHANCED STUDY GUIDE INSTRUCTIONS & PRACTICE QUESTIONS
How to Use This Guide
This comprehensive review contains 130 practice questions covering key concepts from the
WGU C180 Enhanced Study Guide. Each question includes four answer choices, a clearly
marked correct answer, and a detailed rationale explaining the psychological concept.
Category: Psychology — Comprehensive Enhanced Review
1 What do psychologists study? Select the answer that best describes the full scope.
A Only mental illness and treatment
B Only the brain and nervous system
C Biological foundations, mental life, change, self and others, potential and
dysfunction
D Only observable behavior
Why C is correct: Psychologists study biological foundations (brain, hormones, DNA),
mental life (thought processes), change (development across lifespan), self and others
(social interaction), and potential/dysfunction (normal vs. abnormal behavior).
A — This is a narrow view limited to clinical psychology.
B — This is the focus of neuroscience.
D — Behaviorism is one approach, not the entire field.
,2 The scientific method in psychological research includes which steps in the correct
order?
A Form Hypothesis → Conduct Research → Analyze Data → Interpret Data → Publish
Results
B Conduct Research → Form Hypothesis → Analyze Data → Publish Results → Interpret
Data
C Analyze Data → Form Hypothesis → Conduct Research → Interpret Data → Publish
Results
D Publish Results → Form Hypothesis → Conduct Research → Analyze Data → Interpret
Data
Why A is correct: The scientific method follows the order: form a hypothesis, conduct
research, analyze data, interpret data, and publish results. It requires procedures to be free
of personal bias and verifiable.
B — Hypothesis must come before research.
C — Hypothesis must come first.
D — This is the reverse order.
3 A hypothesis is best defined as:
A A statement guessing the relationship among certain parts of a theory
B A confirmed fact
C The result of an experiment
D A research question
Why A is correct: A hypothesis is a statement that guesses the relationship among certain
parts of a theory. It is a specific and falsifiable prediction that can be tested through
research.
B — A hypothesis is not a confirmed fact.
C — Results are findings, not hypotheses.
D — A research question is broader.
, 4 An operational definition is:
A A precise statement of how a conceptual variable is turned into a measured variable
B A dictionary definition of a concept
C The outcome of an experiment
D A research question
Why A is correct: An operational definition is a precise statement of how a conceptual
variable is turned into a measured variable. For example, depression (conceptual) could be
defined as the number of appointments made with a psychotherapist (measured).
B — A dictionary definition is not operationalized.
C — This is not the definition.
D — A research question is broader.
5 Why are ethical guidelines needed within psychological research?
A To prevent physical and/or emotional harm to participants
B To ensure researchers get the results they want
C To save money on research costs
D To make research easier to conduct
Why A is correct: Ethical guidelines are needed to prevent physical and emotional harm to
participants. Requirements include free choice in participating, allowing questions, and the
ability to quit at any point.
B — Ethics protect participants, not researcher outcomes.
C — Ethics are not about cost savings.
D — Ethics may make research more complex.
