PSYC 111: Complete Exam Study Guide (100 Q&A)
Part 1: Introduction to Psychological Science
1. What is psychology?
A: Psychology is the scientific study of behavior and mental processes. It employs the scientific
method to understand how organisms think, feel, and behave.
2. What is the primary difference between a psychiatrist and a psychologist?
A: A psychiatrist is a medical doctor (M.D.) who can prescribe medication and primarily treats
mental disorders from a biomedical perspective. A psychologist typically holds a Ph.D. or Psy.D.
and focuses on psychotherapy, assessment, and research.
3. Who is considered the founder of structuralism, and what was its primary method?
A: Wilhelm Wundt is considered the founder. Structuralism aimed to understand the structure
of the mind by breaking down conscious experience into its basic components (sensations,
feelings, images) primarily through introspection.
4. William James is associated with which early school of thought, and what was its focus?
A: William James is associated with functionalism. This school focused on the purpose and
function of consciousness and behavior—how they help us adapt to our environment.
5. What is the fundamental assumption of the psychodynamic perspective, and who founded
it?
A: Founded by Sigmund Freud, the psychodynamic perspective assumes that behavior and
mental processes are shaped by unconscious conflicts, often rooted in childhood experiences.
6. What does the "ABC" of research methods stand for in psychology?
A: Affect (emotion), Behavior (observable actions), and Cognition (thoughts). A complete study
often measures all three.
, 7. What is the key difference between a correlational study and an experiment?
A: A correlational study examines the relationship between two variables but cannot determine
cause-and-effect. An experiment manipulates an independent variable to observe its effect on a
dependent variable, allowing for causal inferences.
8. In an experiment, what is the difference between the independent variable (IV) and the
dependent variable (DV)?
A: The Independent Variable (IV) is the variable that the researcher manipulates or changes.
The Dependent Variable (DV) is the variable that is measured; it is the outcome that depends
on the manipulation of the IV.
9. Why is random assignment critical in experimental design?
A: Random assignment ensures that each participant has an equal chance of being assigned to
any group in the experiment. This minimizes pre-existing differences between groups, making it
more likely that any differences in the DV are caused by the IV.
10. What is the purpose of an Institutional Review Board (IRB)?
A: The IRB reviews research proposals to ensure that the ethical rights and well-being of
participants are protected, including informed consent, confidentiality, and protection from
harm.
Part 2: Biological Bases of Behavior
11. What is a neuron?
A: A neuron is a nerve cell and the basic building block of the nervous system, specialized for
communication.
12. What is the function of the myelin sheath?
A: The myelin sheath is a fatty tissue layer that insulates the axon of some neurons. It speeds up
the transmission of neural impulses.
13. Describe the "all-or-none" principle of neural firing.
A: This principle states that a neuron will either fire an action potential at full strength or not at
all. There is no partial firing.
14. What are neurotransmitters, and what is the role of serotonin?
A: Neurotransmitters are chemical messengers that cross the synaptic gap between neurons to
bind to receptor sites on the receiving neuron. Serotonin is involved in mood regulation, sleep,
and appetite.
